LEHDOPTERA HETEROCERA. 337 



Fore wings rounded at the tips ; exterior border very oblique. 

 Hind wings short. Male. — Antennae slightly nodose in the middle. 

 Female. — Antennae filiform, smooth, of two colours. Abdomen of 

 the female enlarged, depressed above, ending iu an abrupt point, 

 which is furnished with a quadrate or bifid tuft. 



The genera Thyris, and Arna (Cat. Lep. Het. viii. 72, 75), 

 especially the latter, have much resemblance to this genus. Several 

 species of 2E 'diodes obviously belong to Desmia, and the former 

 genus is here restricted to JE.flavi basal is, and to a few nearly 

 allied species. Some species of Hyalitis are also transferred to 

 Desmia, as they appear to be more nearly allied to it than to //. 

 reginalis, the type of that genus.
