Abstract: This report describes and illustrates egg types seen among species of three families of Macrolepidoptera-Liparidae, Lasiocampidae and Lacosomidae. For reports on eggs of other families of the Macrolepidoptera see the following publications by the author in The Florida Entomologist: Geometridae (1962); Amatidae, Arctiidae, and Notodontidae (1963); Noctuidae (1964); and Sphingidae, Saturniidae and Citheroniidae (1965). The number of species among the Liparidae, Lasiocampidae, and Lacosomidae is moderate to small when compared with the Noctuidae and Geometridae. McDunnough (1938) records 28 species for the Liparidae, 31 species for the Lasiocampidae, and 3 for the Lacosomidae. Except for the Lacosomidae the females of most species deposit their eggs in irregular or more or less uniform clusters. The eggs of these families were found in the field or obtained from females captured at light traps or at light lures and confined in paper or polyethylene bags. They were handled in the same manner as reported in previous papers by the author in The Florida Entomologist.

Abstract: Spencei (1963) described Ophliioinyia caa)ma rae from specimens, rear-ed by F. D. Bennett, infesting leaves of La'ntana camlar a L. in Trinidad, B.W.I., July, 1962. Spencer stated that the leaf mine pattern of Ophioi.nyia caC II}re is a narrow channel riunning primarily along the midrib, with offshoots along the lateral veins, and that pupation takes place within the leafmine channel. The three leaves in Fig. 1 illustrate the variatiorns in the form of the leaf mines.

Abstract: The almost simultaneous discovery in Guatemala and Cuba of the remarkable damselfly described herein is a very interesting coincidence. In July 1962 one of us (TD) found this species in fair abundance at Tikal, in the Peten district of Guatemala; in August the other (PA) found it near Guane in the Pinar del Rio province of Cuba, about 500 miles from the Guatemalan locality. Unfortunately it is not known when this species might first have occurred at Tikal; although the new insect was not found during a biological survey from January to May of 1956 (Kormondy 1959), the Odonata were collected by non-specialists, and Donnelly has been able in less than thirteen days during the summers of 1962, 1963, 1964, and 1965 to more than triple their list of species. The new species could well have been overlooked by these collectors. Four male specimens taken in two states of Mexico during the summer of 1965 by Dennis Paulson suggest that this species might be quite widespread. It is difficult to understand why this insect has been so long overlooked. During our preliminary separate analyses of this new species, we were each initially under the impression that it belonged to the genus Enallagmm. However, Donnelly had been engaged in studies in this genus and found that the penis of the new species was radically different from any New World member of the genus, and indeed was distinctive enough to warrant the establishment of a new genus. Erection of this new genus, however, has not helped to untangle the rather complicated skein of inter-generic relationships among the Neotropical damselflies of the AcanthcagrionEnallagma group. Examination of a number of species in this group during this study has revealed relationships between species hitherto thought not to be closely related and important differences between species thought to be closely related. The development of this problem is beyond the scope of the present paper, however, and only relationships between the new genus and other genera can be discussed.

Abstract: The word "Nabac" is a trademark of the Nationwide Chemical Corporation. It is used to designate formulations of hexachlorophene [2,2'methylene-bis (3,4,6 trichlorophenol)] that are intended for agricultural use. Nabac(? was first tested against citrus rust mite, Phyllocoptruta oleivora (Ashm.) in a routine trial of new materials conducted during July and August of 1963. Since then, Nabac has been tested in a dozen other field trials. The results of these experiments are summarized here.

Abstract: Insect light traps have been operated at the Archbold Biological Station, Highlands County, Florida for seven winters from 1959 to and including 1965. Generally the traps were operated every night. This was especially true of 1960 and 1965. In all cases the traps were run at least 85%G of the nights. Fifty-three species of Scarabaeidae have been taken in these light traps. Forty-seven were listed by Frost (1964). Only nine species can be considered common: Dyscinetus morator Fabricius, Phyllophagat elizoria Saylor, P. glaberrima Blanchard, P. prununculina Burmeister, Cyclocephala parallela Casey, Diplotaxis bidentata Leconte, Anomala nigropicta Casey, Se}rica errans Blatchley, and Bothlynus neglectus Leconte. Species of Aphodius and Ataenius were very common, but it was impossible to identify them at the time they were collected. Dyscinetus morator (Fab.)2 was a conspicuous visitor to the traps during all seven years but especially so during 1962. This species is somewhat common in the eastern United States from Connecticut to Florida and Texas, but apparently is more common in the southern states. Little is known concerning the life history of this species. It is freely attracted to light and has been found beneath debris, in muck about the margins of streams and lakes, in compost, and near pig pens. It should be noted that a large compost pile and chicken yards were adjacent to the area where the traps were operated and may account for the abundance of these beetles during certain years. Table 1 illustrates the relative abundance of Dyscinetus morator during seven winters. Records are given only for the months of January, February, March, and April. Although traps were operated during November and December of 1958 and 1959, relatively few beetles were taken during these months. In November 1958, 126 specimens were taken, 70 of these on 9 November. The same year 226 specimens were taken during December, 178 of these on 9 and 10 December when the average night temperatures were relatively high, 64 and 65 F. In November 1959, only 15 specimens were taken, and in December the same year only 16 specimens were taken. Counts were not made during April of 1959, 1960, and 1961. It is evident that there is great yearly variation in the activity of these beetles. Fig. 1 shows the abundance of Dyscinetus morator during the winter of 1962. The traps were operated every night from 6 Jan. to 25 Feb., with the exception of 12-13 Jan. From 25 Feb. to 21 March they were discontinued because of the abundance of these beetles, which made it almost impossible to obtain other specimens in good condition. The re-

Abstract: Infestations of house flies, Musca domestica L., are a continual problem around poultry establishments where caged laying hens are maintained. The customary undisturbed (for several months) accumulation of droppings beneath the cages provides an excellent breeding medium for house fly larvae. The result is a fly population that tends to intensify during the warm months. The high level of resistance adult house flies have developed toward organochlorine and organophosphorous compounds (Wilson and LeBrecque 1960) has caused a need for more effective materials. Wilson and LaBrecque (1960) met with some success in tests with several compounds as larvicides against natural populations of house flies. The results given in this paper are a continuation of that work. Twenty-one compounds were tested as larvicides against natural populations of house flies breeding in manure under caged poultry in the Gainesville, Florida area. The chemicals were applied as emulsions or as suspensions of wettable powders at the rate of 200 mg active ingredient/ft2. All applications were made with a 3-gallon compression sprayer; 2 gallons of the liquid spray were used for each 800 ft2 of breeding area. Larval density was determined by collecting a large spoonful of manure from each of ten locations where the heaviest infestations were apparent, spreading the samples on a plywood panel, and counting the number of larvae present. The effectiveness of the treatment was determined by comparing the difference in counts made before and on days 1, 2-3, and 7 after application, and, in one instance, on days 9-11, 14, and 21 after application. The formulations used and the results obtained are shown in Table 1.

Abstract: The most recent listing of the Oecanthinae of the world is in Volume 2 of Kirby's Synonymic Catalogue of Orthoptera (1906, p. 72-76). Since then the number of described species has doubled and studies of the species in Africa (Chopard 1932), the United States (T. Walker 1962a, 1963), and Latin America (T. Walker 1967) have revealed new synonymies. The list below summarizes present knowledge of oecanthine taxonomy, nomenclature, and geographic distribution. Keys to the species of Oecanthinae in specific areas are in the studies listed above and in Tarbinsky (1932, USSR), Chopard (1936, Ceylon), and Chopard (1951, Australia). Little has been published on the biology of Oecanthinae with the exception of Oecanthus pellucens of Europe (Chopard 1938, M.-C. Busnel 1954, M.-C. and R.-G. Busnel 1954) and various U. S. species (Fulton 1915, 1925, 1926a, 1926b; T. Walker 1957, 1962a, 1962b, 1963). The following conventions are used in the checklist: After the word Type, a single asterisk (*) means that the condition and place of deposit of the type specimen were confirmed by correspondence. A double asterisk (**) means that I have examined the type specimen. Data concerning the present status of the type specimen are separated by a semi-colon from data on the place and date of collection and the collector. Abbreviations are used for the following museums: Academy of Natural Sciences of Philadelphia, Pennsylvania (ANSP); British Museum (Nat. Hist.), London, England (BM); Universitetets Zoologiske Museum, Copenhagen, Denmark (Copenhagen); Museum d'Histoire Naturelle, Geneve, Switzerland (Genrve); Museum National d'Histoire Naturelle, Paris, France (Paris); Naturhistoriska Riksmuseum, Stockholm, Sweden (Stockholm); University of Michigan Museum of Zoology, Ann Arbor, Michigan (UMMZ); United States National Museum, Washington, D. C. (USNM). Immediately after each synonym and its reference, a reference to substantiate the synonymy is given.

Abstract: In August of 1962, Morestan (formerly Bayer 36205) was included in a routine initial trial of six new compounds against citrus rust mite, Phyllocoptruta oleivora (Ashmead). The performance of Morestan in this test was excellent (Table 1) and led to other tests, not only against citrus rust mite, but also against citrus red mite, Panonychus citri (McGregor), and Texas citrus mite, Eutetranychus banksi (McGregor), as well. This paper summarizes what has been learned about the value of Morestan for control of some of the mites that feed on Florida citrus.

Abstract: In a small sample of oribatid mites collected by Donald De Leon from Coral Gables, Florida, was an unusual species possessing some cuticular structures heretofore unreported in oribatids. These structural oddities, areae spinosae, are not described for any of the genera of Oppiidae listed by Michael (1883), Hammer (1961, 1962), Sellnick (1929), or Willmann (1931). Nor are these distinctive cuticular features reported by Balogh (1961a, 1965) in his reviews of the orbatid genera of the world. It is the presence of these unusual organs that distinguishes the following new genus and species from other known oribatids, especially representatives of the family Oppiidae, where they are placed for the present. The new genus has characteristics in common with other genera of the family from the southern Hemisphere. It resembles superficially the South American genera Aeroppia Hammer, 1961, and Amerioppia Hammer, 1961, in that it lacks lamellae and has a short rounded sensillus, while the notogastral hairs are nearer to Stachyoppia Balogh (1961b) from Central Africa. The new genus differs from Amerioppia in the presence of long, setose interlamellar hairs, and from Aeroppia in the lack of inflated posterior notogastral setae. It differs from Stachyoppia in its lack of lamellae and has a clavate, rounded, rather than a pointed, setose, sensillus. The areae spinosae have been observed since in representatives of other families (e.g. Oribatulidae), but we believe these cuticular organs occur only among the oribatids.

Abstract: In 1956, Carriker described and illustrated as Acutifrons caracarensis (Kellogg and Mann, 1912) specimens taken off Caracara cheriway (Jacquin). At that time, Carriker noted he had been unable to examine the type of A. caracarensis, which was collected off Caracara lentosus (Ridgway); but he suspected the two forms might not be conspecific. I have examined the type material of A. caracarensis, and it is not conspecific with specimens from Caracara cheriway. The new species is herewith described. Acutifrons mexicanus, new species

Abstract: The green peach aphid, Myzus persicae (Sulzer), appeared in unprecedented numbers in a few Florida tobacco fields in 1946. The following year this aphid became a major pest, and it was considered a serious threat to tobacco in all the tobacco growing sections of this country and in Canada and Cuba. It was believed that field infestations of the insect developed principally from aphids brought in with plants from infested seed beds. However, there also was a possibility that new colonies were started by winged aphids which entered the fields from outlying areas. To obtain information on this matter, winged aphids resting on tobacco plants in the field were collected and studied in the spring of 1949. Many of them were the green peach aphid, but several other species were taken. Collections were made on five different dates, and a total of 245 specimens were taken. They included 28 different species, several of them represented by single individuals. Eight of the species were new to Florida and four of these were undescribed at the time of collection. Because so many unusual aphids were taken in 1949, this method of collecting was used in several subsequent years. All of the collections were made in Alachua County, Fla. Except for one year, they were made in the experimental tobacco plantings of the Agricultural Experiment Station at Gainesville. In 1962 collections were made in several commercial tobacco fields in the Alachua and Newberry areas. The success of this method of collecting aphids is due to a characteristic feature of the tobacco plant. Both surfaces of the leaves are thickly covered with sticky glandular hairs. Aphids alighting on the tobacco begin to move about, and soon the sticky material of the leaf hairs accumulates on their legs and they become securely trapped. As long as the trapped aphids remain alive, they can be removed from the plants rather easily with a camel's hair brush dipped in 7O0Gc alcohol. Dead aphids stuck to the leaves soon become dry and brittle, and they are of little value as specimens for identification. The collection data for 11 years are summarized in Table 1. Because of variations in the number of collections made in different years and in the number and size of tobacco plants examined, the aphid catches are not directly comparable. The species recorded are representative of the aphids alighting on the tobacco at the collection periods as all aphids seen on the plants were collected. The green peach aphid was taken in each of the 11 collection years. This species flew to the tobacco in very large numbers in 1957, 1961, and 1962, but infestations in tobacco were not severe in Florida during these years. This does not prove that migrating aphids are not a factor in initiating field infestations, but it does show that severe outbreaks do not necessarily follow a heavy influx of flying aphids. Five other aphid species also were taken in all years that collections were made. Four of these, Aphis gossypii Glover, Macrosiphum euphorbiae

Abstract: The cabbage looper, Trichoplusia ni (Hubner), and the diamondback moth, Plutella maculipennis (Curtis), infest cabbage in southern Texas and southern Florida. Insecticides presently used control these insects but some resistance has been found in both species in the United States. Only by continued testing of insecticides can alternative materials be recommended should those in use fail to provide control. Experiments were, therefore, conducted during 1964 and 1965 at Weslaco, Texas to evaluate various insecticide, insecticide-oil combinations, and high and low volume applications for control of the cabbage looper, and at Homestead, Florida for control of the diamondback moth and cabbage looper.

Abstract: During experiments designed to evaluate the biological control of the Texas citrus mite, Eutetranychus banksi (McGregor), in citrus groves, it was found that counts of these mites and the known biological-control factors present did not adequately explain population increases and decreases. There are several species of predatory mites and a fungus, Entomophthora floridana Weiser and Muma, known to attack the Texas citrus mite. Need to increase count accuracy by refinement of counting technique was indicated. Since methods of counting predators in host mite samples had been verified it was suspected that the error involved estimates of diseased host mites. A laboratory investigation demonstrated that this was true. When Texas citrus mites were cleared in hot lactic acid, fungus tissues and mite structures were sharply differentiated. This led to a rapid, accurate determination of the number of fungus-infected and noninfected mites. At this point, it became obvious that a more complete knowledge of the life cycle and life stages of the fungus would be necessary to differentiate it from adventitious and saprophytic fungi also found on and in the mites. Review of pertinent literature revealed the following: Fisher (1954) first recorded an Entomophthora sp. from Texas citrus mites, noting that it appeared to be different from the unidentified species that she (Fisher 1951) had reported attacking citrus red mites, Panonychus citri. In her 1951 paper, Fisher discussed gross manifestations of diseased mites and presented a general discussion of the life cycle of Entomophthora taken from Steinhaus (1949), Bessey (1950), and Fitzpatrick (1930). Other publications on Entomophthora in citrus spider mites merely listed the association (Muma, Selhime, and Denmark, 1961), or discussed and evaluated fungus-caused epizootics in two species of spider mites (Muma 1955, 1958). The present study was initiated to determine the infective stage and life cycle of, and the epizootiology of the disease caused by E. floridana in Texas citrus mites. Susceptibility of the citrus red mites and six-spotted mites, Eotetranychus sexmaculatus, to the fungus was also investigated.

Abstract: Recently, Selhime and Muma (1966) studied the biology of an entomophthoraceous fungus attacking the Texas citrus mite, Eutetranychus banksi (McGregor). This study and a series of earlier publications including Fisher (1954), Muma (1955 and 1958) and Muma et al. (1961) have indicated the unusual frequency of the fungus in the field and its potential importance in the biological control of the Texas Citrus mite. This fungus, described in the present paper, is not the only Entomophthora known to infect Acarina. Petch (1940) described Entomophthorct acaricida from Halotydems destructor Tucker and later, Petch (1944) described E. acaridis from other infected Acarina. Recently, Batko (1965) recorded Conidiobolus brefeldianus Couch from Tyrophagus perniciosus Zachvatkin and other tyroglyphid mites. METHODS
