PARA.MONGOMA. SYMPLECTA. 485 



the exact corner of the discal cell, there being neitJier 3rd longi- 

 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 5th 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 being illustrated, with 

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

 would be easily obscured by the proximity of the wing to the 

 abdomen. 



As P. albitarsis, 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 antennae of fourteen subequal 

 cylindrical joints becoming smaller towards the tip of the antennas. 

 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 \vartn damp days dancing in the air. I have not seen the 

 species myself. 



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

 pennipes, 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 Paramonyoma.

Head : eyes separated above by a broad frons, nearly contiguous 

 below. Proboscis and palpi moderately short. Anteunse 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 subcylindrioal, with- 

 moderate verticels. Thorax and abdomen normal. Male genitaiia> 

 consisting of two elongate subcylindrical basal pieces with two- 

 blunt horny appendages attached to each of them. Ovipositor 

 of female curved, upper valves poioted, the lower ones- short. 

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

 femora in some species distinctly, though moderately, iucrassated 

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