Subspecific name

Abstract: Of the six species of Australian Rhysida recognized by Chamberlin (1920), three are synonymized and one is excluded from Australia. Three Australian species of Rhysida are recognized: R. carinulata (Haase) and R. nuda (Newport) are redescribed, and a new species, R. polyacantha, is described. These three species are keyed, their distributions in Australia mapped, and some of their important characters tabulated together with those of two related extralimital Rhysida species, immarginata and longipes. R. nuda is confined to Australia. Hence all the extralimital forms of Rhysida to which previous workers have applied the specific or subspecific name nuda should not bear that name. The name R. immarginata may be applicable to some or most of those forms.

Abstract: In this study, thirty species considered monophyletic and congeneric with Macrocneme maja (F.) are characterized, illustrated, and discussed. Fourteen new species are described from South America. Three names are removed from synonomy, one subspecific name is reinstated as a valid species, and nine names are newly placed in synonymy. The author summarizes biological information, and discusses and illustrates patterns of geographical distribution.

Abstract: Limited biological observations on several species of Hornia are reported from California, New Mexico, and the State of Chiapas in southern Mexico. Restudy of available adults and larvae of H. minutipennis Riley indicates that the subspecific name H. m. occidentalis should be applied only to populations from central and coastal California. The relationship of H. mexicana Duges, from central Mexico, to H. neomexicana (Cockerell), from the southwestern United States, is not definitely known due to lack of specimens and to incomplete and inconsistent descriptions of the former. A previously unknown population from Chiapas is variable in the characters used to separate these species, and therefore H. neomexicana is considered to be a subspecies of H. mexicana. The Chiapas population is described as H. mexicana blomi, since its pattern of variation is distinctive.

Abstract: Summary. The Proboscidia of the Bugti beds of Baluchistan consist of form of Bunolophodon angustidens and a small Dinotherium. The Indian B. angustidens is of a small type more primitive than the French forms from Sansan, nearer to Schlesinger's form subtapiroidea than his form typica, but not identical with it. Lydekker's subspecific name var. palceindica may be retained for the present until intermediate forms are found to occur. The genus Hemimastodon is not supported by material in the collection. The Dinotherium is not found to differ from the smaller European forms nor from D. hobleyi of Africa, and it is doubtful in the present state of knowledge whether the Indian Dinotheres are separable from the European.
