The Genus Dcilemcra. 55 



a slight difference in neuration, vein 11 of fore-wings being 

 stalked with 9 and 10. 



A third sub-division of Section II is necessary for the 

 African species, including leuconoii, Hopffer ; in this the 

 hind-legs of the male suffer great modification, the coxae 

 are greatly elongated, the feraoi'a still more so, the tibiaa 

 are all but obsolete and without spurs, while the tarsi are 

 much attenuated and almost equal to the femora in length, 

 and are accompanied by a tuft of hairs as long as them- 

 selves, from the femoro-tibial joint. 



The fourth sub-division contains species without second- 

 ary sexuiil characteristics, and will include all the species 

 heretofore placed under Triphcromcra, Zonosoma, and 

 Lc'ptosoma, amongst which there is no difference whatever, 

 except in the pattern and sometimes as in ccnis in the 

 lenoth of the wino-s. 



As might be expected with moths of weak flight, nearly 

 every island contains its own peculiar form ; this of course 

 does not of a necessity make each a good species, as in 

 haulus, Boisd. = mundipida, Walker, forms of which are 

 found in nearly all the islands (probably in all), from the 

 Philippines to the Solomon Group, and although one can 

 generally trace some small difference in each, the differences 

 are too slight for any attempt to make any distinctions. 



The Family NYCTEMERID^ stood for many years by 

 itself, next to the CALLIDULIDiE, where Kirby puts it 

 in his catalogue of Heterocera. Meyrick, in Proc. Linn. Soc. 

 N.S.W. 1886, p. 687, put the members of this group into 

 the Family HYPSID/E = AGANAIDyE, and though 

 Hampson, in his Moths of India, vol. ii, put them into 

 the ARCTIIDiE, they have now been put in the National 

 Collection with the Aganaidse, which is evidently their 

 proper place, and they form a sub-division of that Family. 



Key to the sub-divisions of Deilemera. 

 Section I. Veins 6 and 7 of hind-wings not stalked, palpi short. 



A. Antenna3 not pectinated (Atasra) 



B. Antenna) shortly pectinated (Pitasila) 



Section II. "Veins 6 and 7 of hind-wings stalked, palpi longer, 



antennae with long pectinations. 



A. Both wings of male abnormally developed. (Deilemera) 



B. Male with long tnft of hair to fore tibias. (coleta (jrouij) 



c. Male with abnormal hind-legs (leuconoe groitj}) 



D. Without secondary sexual cliaracters. (Tripheromera*)
