432 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



I have not taken this species, and know of no other specimens 

 but the original types ; two of these are stated to be from Tas- 

 mania, the third from " Australia," which probably means 

 Tasmania in this case. 



9. ACROPOLITIS, n. g. 



Thorax with large double crest. Antenna? in male thickened, 

 serrate, strongly biciliated. Palpi moderately long, straight, 

 porrected, second joint triangularly scaled, terminal joint distinct. 

 Forewings oblong, costa in male broadly folded and bent before 

 middle, in female evenly arched at base, thence nearly straight, 

 apex rectangular, hindmargin obliquely rounded. Hindwings 

 rounded-trapezoidal, broader than forewings. Forewings with 

 veins 7 and 8 stalked, 7 running to hindmargin. Hindwings 

 with veins 3 and 4 rising apart, 5 closely approximated at base 

 to 4 or rising from the same point with it, 6 and 7 separate (in 

 A. signigerana stalked). 



This genus forms the type of the group to which Adoxophyes, 

 Tkrincophora, Pyrgotis, and (less intimately) Aristocosma belong ; 

 characterised by veins 3 and 4 of hindwings rising apart but 

 near together, 5 closely approximated to 4, forewings with veins 

 7 and 8 stalked, and broad costal fold in male. From Adoxophyes 

 and Aristocosma it differs in the crested thorax, from Thrincophora 

 in the straight porrected palpi ; it is very near to Pyrgotis, and 

 the only points of distinction that I have been able to define lie 

 in the more oblong forewings, and the separation of veins 6 and 

 7 of hindwings, to which latter character A. signigerana presents 

 an exception ; but the genera are readily separated by superficial 

 characters, and I think will be found capable of definition. 



The species are mostly rather large and well-marked insects, 

 having commonly a longitudinal black dash in the disc of fore- 

 wings, and resemble some of the larger species of Capua, to 

 which the genus is in fact nearly allied. In habit they are
