Moth. — Head moderately proiuiiient; front triaii gn la r, broad above; below tbe base of each 

 aiitcDiui is a large spreading' tuft of long sc;iles reaching Inilfway down the front and partially 

 covering the eyes, which are naked, not hairy. Antenn;!- in c? with long slender pectinations, the 

 branches extending to the tips; in the 2 the j)ectinations hardly longer than the joints. Palpi 

 large, long, stont, ascending porrect, the third joint rather short, thick, but distinct; .second joint 

 not hairy at the end. Ma.xilhe small, r;ither short. 



Thorax with a remarkably high pointed tuft on the front part and sending a ridge down each 

 side to the end of the tegulie; beneath, very hairy. Fore wiugs distinctly pointed at the apex, 

 which is somewhat more so than in Datana; costa convex on the outer half, especially in the 5 ; 

 outer edge regularly convex behind the apex, but little shorter than the internal edge, more 

 oblique in 9 than in <? ; in 2 slightly scalloped. Discal veins .situated within the middle of the 

 wing, so that all the venules are longer than usual. A rather short subcostal cell; apical region 

 of the costa very narrow, the tirst, second, third, and fourth subcostal venules ending very near 

 each other and near the apex. Hind wings somewhat produced toward the apex; outer edge 

 regularly convex, much longer than the intern;il edge; the lower discal vein oblique, much 

 curved; both di.scal venules, as in Datana and Cluphisia, situated nearer the base of the wing 

 than usual.
