in the ^ nearly as wide as, and about one-third longer than, the 
thorax, somewhat flattened ; the first segment, anterior half of the 
second, the anterior bordei’s of the third and fourth segments 
slightly, and beneath the first four segments, ochraceous ; pos- 
terior half of the second, and the two following segments deep 
brown ; fifth and sixth segments wholly black ; forceps brown ; 
in the 2 as wide as, and nearly twice the length of, the thorax, 
somewhat flattened ; dorsal segments soi’did ochraceous, indis- 
tinctly bordered posteriorly with brown, beneath sordid ochra- 
ceous ; lamellse of the ovipositor ochraceous ; ^ and 2 densely 
pubescent. Coxje, femora ochraceous ; tibiae with their spurs 
somewhat smoky -ochraceous ; tarsi and tibial spines almost 
fuliginous in a cei’tain light. In the fore-legs the tibiae about J 
longer than the metatarsus (3:2). Wings considerably longer 
than the abdomen, pellucid, with a pale brownish-grey tint, 
somewhat smoky ac the apex ; veins brown, the costal and first 
and second longitudinal veins much darker than the rest ; mar- 
garitaceous reflections. Auxiliary vein joining the costa somewhat 
before the origin of the third longitudinal vein ; first longitudinal 
vein reaching the costa a little beyond the base of the fork ; 
marginal cross-vein very short, thick, situated not far from the 
tip of the first longitudinal vein and immediately before the base 
of the fork ; costal vein extending beyond the tip of the second 
longitudinal vein | the distance from that to the tip of the 
anterior branch of the fork ; tip of the anterior branch of the 
fork situated as much above the apex of the wing as that of the 
posterior branch is below it ; fifth longitudinal vein indistinct, 
extending rather more than half-way to the margin, its basal 
portion scarcely visible ; a very short stump of a sixth longitudinal 
vein.
