the peculiar appearance of the vertex being drawn forward, as it 

 were, into a pointed flap, which hangs down between the eyes ; 

 the sides of the irons, near the eyes, being bent inwards ; the 

 occiput, near the eye-mai'gius, is whitish. Proboscis yellow, with 

 large yellow labella at tip ; palpi dark brown. Autennal scape 

 with the 1st joint long, cylindrical, yellowish ; 2nd broader and 

 shorter, rounded, a little greyish ; the flagellum with lighter 

 brownish yellow, elongate, oval joints ; distinctly pubescent, with 

 hairs of different lengths and a verticel of a few much longer 

 hairs on each joint. Thorax dull greyish brown ; a little yellow ish 

 about the pleura, on the shoulders and on the broad post-sutural 

 depression ; no distinct dorsal stripes, but there is in some speci- 

 mens an ill-defined indication of them. Scutellum and meta- 

 notum more or less concolorous, the whole posterior part of the 

 thorax generally more yellowish than the anterior half. Abdomen 

 brow^nish or brownish yellow, hind margins and sides of segments 

 often blackish. Some soft yellow hairs over dorsum and sides. 

 Genitalia of the male consisting of a pair of elongated cylindrical 

 claspers, of one joint only, with a small black terminal hook which 

 appears to represent all there is of the second joint. Ovipositor 

 of female brownish yellow 7 , normal in shape, small. Legs brownish 

 yellow, trochanters nearly as long as the coxae, femora with a 

 blackish subapical ring. Wings yellowish grey. The auxiliary 

 vein lying very close to the 1st longitudinal and ending in the 

 costa opposite the marginal cross-vein, the 1st vein ending half-way 

 between the marginal cross-vein and the tip of the wing ; the 2nd 

 longitudinal vein beginning much before the middle of the wing, 

 at a comparatively small angle, and forking just before the 

 marginal cross-vein, the branches being parallel and the praefurca 

 being half the length of the vein ; the 3rd vein originating a little 

 before the fork of the 2nd, forming a distinct angle at its bend, 

 thence running parallel with the lower branch of the 2nd vein 

 straight to the wing-tip ; anterior cross-vein moderately long, in a 

 line with the basal section of the 3rd vein ; the 4th vein forking 

 almost exactly by the anterior cross-vein, thus forming a short 

 basal side to the 2nd posterior cell (the discal cell being absent) ; 

 the upper branch of the 4th vein straight, simple, nearly parallel 

 with the 3rd vein, the 1st posterior cell being slightly narrow at the 

 tip ; the lower branch widely forked at half its length ; the 

 posterior cross-vein placed just before the fork of the 4th vein ; 

 the 5th and 6th veins nearly straight ; the 7th, after quitting the 

 6tr, takes a moderately wide curve and, towards the tip, again 

 turns downwards to the margin. The hairs on all the veins very 

 small and quite inconspicuous. Halteres yellowish. 



Length 4-5 millim.
