Abstract: Loranthomitoura, new genus, is described for five North American hairstreak butterflies which utilize Arceuthobium as a larval host. These species were previously placed in the genus Mitoura with other taxa which utilize hosts in the Cupressaceae. Separation of Loranthomitoura from Mitoura is based primarily on characteristics of the immature stages, especially first instar chaetotaxy. Larval and adult features indicate that Loranthomitoura may have greater affinity with Incisalia.

Abstract: Summary. Former studies have shown that there is an interspecific allometric relationship between eggsize and adult body size in butterflies and skippers. This is here re-assessed at the family and subfamilylevels in order to determine to what extent the overall trend is uniform through different taxonomiclineages. The results suggest that different subtaxa are characterised by different allometric slopes. Al-though statistical analysis across species means is known to be potentially misleading to assess evolu-tionary relations, it is shown that the comparison of apparent patterns (based on species means) withinferred evolutionary trends (based on independent contrasts) may help to understand the evolution ofegg size in butterflies. Further, intuitive reconsideration of statistically non-significant results may proveinformative. As an example, argumentation in favour of a positive association between large egg sizeand the use of monocotyledon plants as larval food is presented. Taxa where atypical allometric trendsare found include the Riodininae and Theclini (Lycaenidae), the Graphiini (Papilionidae), and theHeliconiinae (Nymphalidae).Key words: Allometry, butterflies, Hesperioidea, egg size, body size, life-history, Papilionoidea,wing-length

Abstract: Aspects of the life history of Ahmetia achaja (Fruhstorfer) and a description of the immature stages are presented. Larval chaetotaxy and morphological features of the eggs and pupae suggest a close phylogenetic relationship with some other members of the subtribe Cheritrina.

Abstract: The aim of this paper is to provide a critical review of relevant data about the myrmecophilous relations between larvae and pupae of Iberian lycaenids and ants. The final result of this study is that the number of locations where these relations have been found has increased. There are 18 records which are new for the Iberian Peninsula as well as for the rest of Europe. Six records are given for the first time for the Iberian Peninsula, but they were already registered from other European localities. Psuedophilotes abencerragus is cited for the first time as a myrmecophilous species. Myrmecophilous relationships have been recorded in a total of 32 lycaenid species, belonging to 16 genera and in 26 ant species from eight genera. Myrmecophilous lycaenids belong to tribes Theclini, Eumaeini and Polyommatini, while the Lycaenini tribe does not share this behaviour. Ants having a relationship with lycaenids belong to subfamilies Formicinae, Dolichoderinae and Myrmicinae.
