Type, P. liylax, Fabr., from Java. 



Range. Indo-Malayan Region. 



cf $ . Fore wing : elongate ; costa strongly arched ; apex 

 rounded ; termen convex ; dorsum straight or very slightly 

 sinuous; cell about half length of wing; upper discocellular t 

 very oblique, almost longitudinal, thickened; middle and lower 

 discocellulars slender, almost vertical, slightly concave, subequal ; 

 vein 3 from well before lower apex of cell, vein 4 from lower apex 

 of cell, vein 5 from cell at junction of middle and lower disco- 

 cellulars ; vein 6 from upper apex of cell, its base well separated 

 from base of vein 7 ; vein 8 absent ; vein 9 out of middle of 7, 

 10 free, 11 anastomosed with vein 12 ; vein 12 ending on costa 

 very nearly opposite or a little before apex of cell. Hind wing : 

 elongate oval ; costa slightly arched, termen very strongly rounded 

 and arched, apex and termen both rounded, dorsum straight. 

 Antennae slightly longer than half length of fore wing, club 

 comparatively broad and spatulate ; eyes naked ; palpi subporrect, 

 second joint thickly clothed with adpressed scales, third joint 

 aciculate. 



Two forms are known from within our limits. 



* Eyes hairy in one form. 



t I take the upper discocellular to be the veinlet between bases of veins 6 

 and 7. In Pithecops, as in a very large number of the genera of the Lyc&nidts, 

 the general movement of the veins upwards towards the costa lias caused this 

 vein to fall into line with the subcostal, and to become to all appearance a 

 portion of that vein.
