forming a biconvex angle with the mid lobe. The pattern anteriorly 
transverse to nearly the level of the side lobes, elsewhere regular and 
raised. Chiefly on the side lobes and before the furrows on each side occur 
a few scattered very minute bristles. Scutellum (10 : 9) broadest preapi- 
cally and overhanging the post-scutellum. The basal abscissa is just 
one hall the length. Pattern like the mesonotum, finer behind the suture 
and largest and coarsest on the broad edge above the post-scutellum ; 
narrowly bare medianly, with about Lb : Lb bristles and 2 small sensory 
pustules very wide apart near the apex. The last 3 bristles, on the over- 
hanging portion on each side are stronger than the others. Axillae with 
18-20 minute bristles chiefly near the suture. Sternopleura, mesoster- 
num entirely finely raised reticulate, the pleural portion concave and 
bare, the sternal quadrate area with a number of minute bristles laterally 
and posteriorly, but mainly bare. Episternite anteriorly rough, smooth 
behind. Upper portion of the epimeron smooth but reticulate lower 
with a coarser distinctly raised pattern. The prepectus is long and 
narrow but the actually exposed portion (a little over half the depth of 
the sclerite) is in the form of a rough isosceles triangle. Metanotum : 
{a) post-scutellum broad, band like sub-pentagonal, with little longitudinal 
rugae on its surface (6) area with raised transverse reticulation bounded 
posteriorly by a close set row of minute punctures before the propodeon. 
Side pieces anteriorly raised reticulate, posteriorly smooth with 5-6 
longitudinal ridges. Propodeon on each side of the short median keel 
are two descending rough triangidar areas ; spiracles oval, flattened 
on the inner side, rims distinct. Round the spiracles on outer aspect 
is a flat gleaming sulcus and the surface beyond is reticulate or striate, 
but not much raised. The sulci, not connected with the spiracles by any 
branch, are crossed by one or two small longitudinal rugae. Below the 
spiracles the metapleura bear numerous short soft bristles. Behind 
the spiracles the surface is a little swollen. The petiolar emargination is 
slight, gently concave. From above, the posterolateral angles are 
distinct but not produced. 
Wings. Forewings (fig. 19, a) (8 : 3) length 2-8 mm, breadth LOS mm. 
Submarginal : marginal : radius : postmarginal 22 : 1 1 : 6 : 8. There are 
4 clear pustules on the junction of submarginal and marginal near the 
apex of the submarginal cell. 22-24 bristles on the submarginal vein 
and about 28 short major bristles overlapping on the marginal and 
postmarginal, the latter continuing a short distance beyond the last 
stronger bristle. The radius bears about 18 bristles. In the apical cell 
there is a complete submarginal row of bristles (26-30) and a second row 
of slightly longer bristles (6-8) accompanies the first to rather less than 
half from the apex. Upper surface ; nowhere except at the end of the
