CYRTOSIA nov. gen. 



Front of the head narrow. Palpi long, slender, slightly ascending, 

 terminal half passing beyond the front; third joint long acute. An- 

 tennae simple in % , hardly thickened at the base; in 9 a little more 

 slender. Thorax slender. Primaries half as broad as long; costa more 

 convex than usual ; apex a little produced, subrectangular; the outer 

 margin much rounded at the internal angle, the fringe reaching to the 

 middle of the wing. The two branches of the 3rd subcostal are nearly 

 of the same length, the triangular interspace being half as broad as long. 

 The subcostal nervure is very remote from the costa. 



Secondaries reach to the tip of the abdomen, in the 9 passing a little 

 beyond. Costa straight, apex rounded, outer margin very full, inner 

 angle rounded continuously with it. 



Legs slender, pilose, with long scales; hind tibial spurs long slender, 

 of nearly the same length. Abdomen long, tip acute in S ; in 9 short 

 with a spreading anal tuft. 



Coloration consists of different shades of brown, with two oblicjue 

 transverse lines from the inner margin outward towards the costa, the 

 outer shortened by a line curved outwards from beyond the middle of 

 the costa to a little above the inner angle, forming an inverted y. 



The narrow front, the long, slightly a.scending palpi, the simple, 

 slender antennse, and the very convex costa and style of coloration, will 

 easily distinguish this genus from the remaining genera of Cochlidiae 

 with simple antennse.
