 of femora with a tuft of hairs at the distal ends, the hind femora with a row of 

 sparce fine spines, gradually lengthening towards the distal end, mid femora 

 with more numerous and stouter spines than those of the hind ; anterior tibiae 

 keeled, the spines long and numerous, claw-hooks well developed, situated at

 subequilateral, the hind larger than that of fore, both entire ; sectors of arc in 

 both wings fused for a long distance ; 1 cubital nervure in the forewing, 2 in the 

 hind ; subtrigone in the fore-wing 4-sided ; hypertrigone of forewing traversed 

 once, that of hind entire ; 1 or 2 supplementary nervures to the bridge ; 4th, 

 (nodal sector) and 5th (subnodal sector) nervures strongly curved opposite the 

 stigma ; 5a (Rspl) of great length, almost reaching the termen ; 7a (Mspl) obso- 

 lete ; 1 row of cells between it and the 5th nervure ; discoidal field narrow, of 1 

 row of pells to its inner two thirds, dilated at the termen ; anal loop small of 

 about 9 cells, stunted, its outer end a little distad of the outer line of trigone ; 

 8th (Cui.) nervure from the anal angle of the trigone ; membrane moderately 

 large ; stigma small (2 mm), lozenge-shaped. 



Abdomen moderately long and slender, tumid at the base, 3rd to 6th attenu- 

 ated and cylindrical, (much compressed laterally in the female) 7th to 9th seg-

Anal appendages small, as long as the combined length of abdominal segments 

 9 and 10, subcylindrical, tapering. 



Vulvar scale conspicuous, acuminate, ridged and traversed with striations at 

 its distal end. 



The genus is an African one, represented by a single species only within Indian

 cast by a forest of gigantic colladiums.
