Moth . — Head niotlorjitely prominent; front triangular, broad above; below the base of each 
unteuna is a large spreading tuft of long scales reaching lialfway down the front and ]>artially 
covering the ej'es, which are naked, not hairy. Autennaj in <3 with long slender ])ectinations, the 
liranches extending to the tips; in the $ the peiTinations hardly longer than the joints. Palpi 
large, long, stout, ascending porrect, the third joint rather short, thick, but distinct; second joint 
not hairy at the end. Maxilhe small, rather short. 
Thorax with a remarkably high pointed tuft on the front part and sending a ridge down each 
side to the end of the tegnhe; beneath, very liairy. Fore wings distinctly pointed at the apex, 
which is somewhat more so than in Datana; costa convex on the outer lialf, especially in the $ ; 
outer edge regularly convex behind the apex, but little shorter than the internal edge, more 
obliipie ill 9 than in <5 ; in $ slightly scalloped. • Hiscal 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 first, 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 internal edge; the lower discal vein oblique, much 
curved; both discal venules, as in Datana and Gluphisia, situated nearer the base of the wing 
than usual.
