MICKOLEPIDOPTEUA OF NEW GUINEA 
173 
The Tortricinae of the Tortricidae predominate in the collection; the 
material available amounts to 16 apodemic genera with 50 endemic species 
and 22 endemic genera with 98 species. Leaving out of consideration the 
genera already discussed in the preceding chapter we shall briefly review 
the remaining ones, as far as they are of importance in connection with 
our problem. 
Paracliorista is an extensive endemic genus, represented in New Guinea 
by 20 species; one straggler is known from Java, another from India. 
Of the representatives of the Australian element of the fauna may be 
mentioned the exogenic genera Isochorista, Thrincophora, Aeolostoma and 
Capnoptycka, all being endogenic for' the Australian continent; at the 
other hand, P ttrnozygu and Spatalistis are the most important exogenic 
genera of Indian origin. The small genus Neocalyptis occurs in both Java 
and New Guinea ; its character is as lar not clear, hut it may be of Malayan 
origin. 
Zacorisca and Isotenes occur also in the Moluccas, the former genus 
may probably be diendogenic for those islands and New Guinea, as the 
Moluccan species are considerably specialized and different from the 
Papuan ones. The distribution of these genera was already discussed on 
pages 35 and 37 of part I. 
Of the endemic genera may be mentioned Rhomboceros, with peculiarly 
shaped antennae in the male; it is correlated through the nearly allied 
A plastoc.eros with a group of Cnephasiini of Malayan origin; furthermore 
Tremophora, a strange genus with a paired sense organ in the basal segment 
of the abdomen in the two sexes, a feature unique in the entire order of 
Lepidoptera; the appearance of these organs in a single genus of the 
Tortricidae is highly intriguing, the more because the closely allied genus 
Mesocalyptis does not possess them at all. And at last the remarkable 
mimetic Chresmarcha, already discussed at some length in the systematic 
part (part I, pages 163 — 164); we shall mention this genus once more at 
the end of this paper. 
The Eucosminae are less numerous than the preceding subfamily 
in the ratio of 1 as against 3 (cf. part I, pages 29—30). Of the five endogenic 
genera recorded in Table II, Hermenias is the most important; it was 
discussed already in the preceding chapter; Anathamna, of which a fifth 
Papuan species has been described in the second part of the present paper, 
seems to be endogenic, as only one species was recorded from India, one 
from the Pacific region and one from Australia. Bathrotonux occurs also in 
Australia, but the new r species from Mist Camp is strongly differant from 
its Australian congeners. Endothenia and Sereda, finally, have a puzzling 
distribution, the former was recorded from Europe and North America, 
the latter from North America only. 
Metaschistis is the most important of the endemic genera, because we 
expect that much more species than the seven described in this paper 
will be detected in other allied genera to which they may hitherto have
