some lights gives the clypeus the appearance of being longitudi- 

 nally striated; connected at base with the interantennal promi- 

 nence by a short narrow carina. Head very finely rugulose in 

 front, delicately punctured on occiput; the whole thorax finely 

 punctured, scutellum higher than mesonotum with a depressed 

 transverse line at base; median segment very finely rugulose, with 

 grey pubescence, obliquely truncate from postscutellum. Abdom- 

 inal sparsely punctured above, more coarsely beneath. First 

 segment narrow at base, as broad at apex as second, beneath 

 prominent in middle with a small oblique subtriangular truncation 

 at apex. Sixth segment beneath with a spine at apical angle on 

 each side. Dorsal plate of seventh segment coarsely longitudi- 

 nally striated, rounded at apex. Hypopygium finely transversely 

 striated above, with a spine on each side near base, thence rather 

 narrowly produced, gradually narrowed into a sharp, slightly 

 recurved, apical spine. Black; clypeus, mandibles except at 

 apex, the prominence between antennae, margins of eyes narrowly 

 interrupted at apex, margins of prothorax, anterior margin 

 narrowly interrupted in middle, tegulae, a spot on rnesopleurse 

 at base of forewing, another very small one behind it, a transverse 

 band near apex of scutellum, a spot on each side at anterior 

 .angles, postscutellum, an irregular longitudinal band on middle 

 and a longitudinal band on each side of median segment, a 

 transverse band on the six basal abdominal segments, interrupted 

 in middle and wider beneath than above, coxae beneath and a 

 line beneath posterior and intermediate femora yellow; tibiae, 

 tarai, apex of sixth abdominal segment and seventh segment dull 

 ferruginous. Wings very pale, flavo-hyaline, nervures fuscous. 

 Length 22 mm. 



9- Head convex, sparsely punctured in front, almost smooth 

 on occiput, without any depressed space ; eyes oval, oblique, 

 situated at some distance from base of mandibles. Pronotum 

 shining, with a few small, scattered punctures, a row of punctures, 

 each with a long hair on anterior margin, as broad as head, 

 slightly narrowed posteriorly, anterior margin almost straight, 

 posterior margin broadly emarginate. Median segment very
