PARAMONGOMA. SYMPLECTA. 485- 



the exact corner of the discal cell, there being neither 3rd hm/i- 

 tudinal vein nor anterior cross-vein. There are only three posterior 

 cells, of which the first two are subequal, with obtuse-pointed 

 bases ; the posterior cross-vein is a little beyond the base of the 

 discal cell, which is about twice as long as broad. The anal cell 

 is open ; apart from this, the 5tli and 6th veins bear the same 

 relation to each other as in Mongoma. The 7th vein is not 

 shown, perhaps owing to the full insect benag illustrated, with 

 the wings rather close to the body ; in this position the 7th vein 

 would be easily obscux-ed by the proximity of the wing to the 

 abdomen. 



As P. cdhitarsis, DoL, will probably be found to occur in South 

 India or Ceylon, and has been made the type of a new genus, it is- 

 advisable to append a brief description of it. 



The species is greyish brown in colour, with short pubes- 

 cence ; head globular : eyes large, black, kidney-shaped ; proboscis 

 moderately long. Flagellum of antennas of fourteen subequal 

 cylindrical joints becoming smaller towards the tip of the antennae. 

 Abdomen narrow, tip pointed and black. Legs very long, tarsi 

 snow-white. Doleschall speaks of only two posterior cells, but 

 this is only due to a different method of naming them. Found 

 on warm danip days dancing in the air. I have not seen the 

 species myself. 



But for the difference in venation it must be very like Mongoma 

 penni^^es, Os. Sac, but the conspicuously thickened tips of the 

 white middle tarsi will at once distinguish the latter species. 



Mongomella, End., is an absolute synonym of Paramongoma.

Head: eyes separated above by a broad fi"ons, nearly contiguous 

 below. Proboscis and palpi moderately short. Antenna 16- 

 jointed, moderately long or somewhat short ; if bent backwards 

 they would not reach the root of the wings ; scape with 1st joint 

 cylindrical, 2nd shorter and rather broader, both stout ; flagellar 

 joints, especially the basal ones, short, oblong or subcylindrical, with 

 moderate verticels. TJiora.v and abdomen normal. Male genitalia 

 consisting of two elongate subcylindrical basal pieces with two 

 blunt horny appendages attached to each of them. Ovipositor 

 of female curved, upper valves pointed, the lower ones short. 

 Legs rather long, pubescent, in some species conspicuously so ; 

 femora in some species distinctly, though moderately, incrassated 

 at tip ; middle pair of legs rather shorter than toe others ; tibiae
