c? 2 . Margin of anterior end of median lobe of vertex bisinuous 

 ■witb a minute blunt projection on each side of the middle line. Eyes 

 with a minute, slightly convex circular non-faceted spot or tubercle 

 representing a corneal spine. 



Tegmina : a finger-print-like mark at the base forming a curved 

 band across the closed oigans of flight, a marbling along the marginal 

 field, and some short streaks on the longitudinal veins — deep rich brown, 

 and some obscure brown blotches on the membrane, which in the 5 is 

 clouded with greyish whity-brown, but in the male is almost perfectly 

 hyaline ; the anterior and posterior prongs of the anterior ulnar are 

 respectively I- and 4-brauched ; the dividens runs to the posterior 

 margin. 



Wings : (? the anterior margin and apex marbled with dark brown 

 and the rest hyaline : 2 the anterior margin and apex moi-e extensively 

 and deeply marbled with dark brown ; a tesselated pellucid violet-fuscous 

 blotch of greater or less extent near the base of the posterior area, 

 which is followed by broken and anastomosed concentric waves of the 

 same colour, and also of varying extent and intensity, extending be- 

 tween the seventh plicate vein and the anterior mai-gin to the outer 

 margin, and, when less developed, leaving an ante-apical roundish patch 

 of sub-hyaline in the anterior area. 



Four posterior femora with three sub-triangular foliaceous lobes 

 near the apex, one on the upper or posterior of the dorsal crests, and 

 two on the two ventral crests, all arched proximally and sub-dentate 

 distally; tibiae with one foliaceous lobe extending from the knees to 

 the middle of the joint on its dorsal crest and with their two ventral 

 crests foliaceously expanded throughout increasingly from the base, so 

 much so in a female from Ceylon that the joint when viewed from below 

 has a long spatulate outline.
