166 HYMENOPTERA FROM SARAWAK, 
duced slightly in the middle above and largely and roundly in the 
middle below, a small square mark in the middle above the 
antenne, a line on the under side of the scape, a line on the 
apex of the pronotum, narrowed in the centre, two marks on 
the centre of the  scutellum, two of similar size on the 
post-scutellum, a small oval mark on the sides of the median 
segment, two large oblique ones on its sides, which become gra- 
dually wide towards the apex and a large longish mark, broad- 
er on the upper than on the lower half, on the pleure helow 
the tegule and a narrow line, slightly interrupted in the middle, 
on the apices of the 1st and 2nd segments, yellow. Wingsal- 
most hyaline, with a distinct violaceous tinge; its apex and the 
apex of the costal cellule smoky-violaceous, the nervures and 
stigma black. 
Length 14 to 15 mm. 
Hab. Kuching. 
Front and vertex strongly and closely punctured, except on 
the former on the sides below. The clypeus is as strongly but 
not so closely, punctured ; its apex, sides and a mushroom-like 
mark in the centre are black; it is wider than long; its apex is 
about half the width of the top and is slightiy, broadly incised, not 
transverse. Pronotum smooth and shining. Mesonotum, except 
on the sides at the apex, strongly and closely punctured. Scutel- 
lum flat, somewhat strongly, but not closely, punctured ; on the 
basal depression are five stout keels. Metanotum with a large, 
triangular punctured band in the centre at the base; the central 
depression becomes gradually wider from the upper third, which 
is a little narrowed at the base and is bounded by a stout trans- 
verse keel at the apex. Pro-and mesopleure coarsely rugosely 
punctured. Metapleuree coarsely shagreened and sparsely punc- 
tured. The basal three seements of the abdomen are closely punc- 
tured. The fore femora are broadly yellow beneath and there 
isa line, narrowed above, on the upper half of the fore tibie. 
The 2nd cubital cellule is triangular, the nervures almost touch- 
ing above; the 2nd transverse cubital nervure is interstitial. 
When fresh the body was probably thickly covered with pale 
pubescence.
