Wings elongate, at least three times as long as broad, subspatulate in shape. 

 Neuration reaching to one-half or just beyond, and very little bent at the junction 

 of the marginal and submarginal. Submarginal cell narrow, with one minute 

 bristle on the upper surface at one-third from the radix, and 2-4 apically. Sub- 

 marginal vein with four short stiff bristles, one stronger on the marginal before 

 that vein reaches the costa, 6-8 major bristles fringing marginal and postmarginal 

 combined, while dorsally these veins bear 9-12 short appressed bristles. One 

 bristle on radius, which is acutely inclined towards the costa. Basally the wing 

 is narrowed, showing a few bristles below the submarginal. Across the wing, at 

 the junction of the marginal and submarginal, is a sloped indistinct bare area, and 

 another broad " hairless line," much better defined and roughly parallel to the 

 first, crosses the wing from the end of the radius. This second track does not 

 reach the posterior edge, before which one or two rows of the usual discal ciliation 

 intervene. It is similarly cut off from the small clear spot outside the radius,

generally by one, sometimes by several, rows of bristles. The clear path shows 

 scattered black dots, which are not the bases of broken-off bristles, but under an 

 oil immersion are seen to be excessively minute prickles (rudimentary bristles ?) 

 set in the wing membrane. Beyond the bare track the discal ciliation is regular 

 and dense, coming evenly up to the margin everywhere, but tending to form an 

 isolated isoclinal row parallel to the costa on the apical half. Marginal cilia on 

 costa very short and dense, sparser and longer apically, longest on the distal 

 two-thirds of the hind margin and shortened again after the frenulum. Hind wings 

 not much shorter than the fore wings, with no submarginal cell, narrowed basally 

 and very elongate (up to eight times as long as broad). Posterior fringe long, equal 

 to the extreme breadth (at the hooks). Costal fringe moderate. There is a row 

 of minute bristles along the costa and a distinct isoclinal row subcostal in position. 

 Discal ciliation otherwise sparse, varying specifically. 



Legs. Fore legs : femur with no strong ventral bristles, except a (coloured) 

 longer anterior one and a shorter (hyaline) posterior one, subapical in position ;
