scutellum to the tegulae), propodeum and front half of abdominal tergum 2, the 
lower portion of the mesepisternum together with the mesosternum and 
mesepimeron and the meta-sternum and metepimeron, the middle of hind 
coxae, and the abdominal sterna. Wings tinged with yellow, especially fore- 
wings ; hind wings nearly hyaline ; stigma dark brown ; costa and venation 
brown. 
Length 17 to 18 mm. ; forewing 14 to 15 mm. ; antenna 3 mm. 
Pubescence very sparse, almost entirely absent from head (except mouthparts) 
and thorax, very short and scattered on ventral surface of abdomen. 
Head. — Face with sparse coarse punctures ; head behind antennae more 
strongly punctured especially on depressed borders to postocellar area and 
temples ; malar space about half-length of pedicellum ; antenna 7-segmented ; 
about as long as shortest distance between eyes ; clavate from apex of 5th 
segment ; distance between the hind ocelli greater than distance from ocellus to 
eye ; median fovea and frontal furrow fused to form a pear shape depressed 
area including the front ocellus ; lateral furrow starts on about a level with 
the front ocellus and continues back as a slight dejDression to the vertex ; 
post-ocellar area slightly convex and rounded. 
Thorax. — Shining all over with coarse scattered rounded punctures becoming 
dense on the front and side lobes of the mesonotum, especially on the middle 
of the side lobes, and very sparse on scutellum which is strongly contracted 
behind, slightly depressed longitudinally in the middle and with very small 
appendages behind ; mesosternum and metapleurae unpunctured. Abdomen 
with transverse rugulose sculpture. 
$ Colour. — Yellow except for the following which are black : tips of 
mandibles ; the ocellar region and a band stretching backwards to the vertex 
each side of the post-ocellar area ; pronotum in front and side lobes of mesonotum 
(except the raised margins of the side lobes stretching from teguke to 
scutellum) ; depressed parts of metanotum ; dorsal parts of abdominal terga. 
Wings yellowish hyaline with patch of scales (? androconia) occupying sub-costal, 
first discoidal and first two cubital cells of forewing ; stigma brown ; tegula 
and venation yellow in basal half of wings, brown in apical half. 
Length 13 mm. ; fore wing 11 mm. ; antenna 3 mm. 
Structure as in female except for wings, genital segments and slightly 
denser puncturation noticeable on mesopleurse where between punctures the 
surface is dull and rugulose.
