each side, scutellum transverse, metanotum somewhat convex, 

 broader than the pronotum, separated from the scutellai'y region by 

 a deep transverse groove, almost vertically truncate and with a row 

 of small tubercles on the edge of the declivity ; abdomen ovoid, 

 basal segment pedunculate and then broadly dilated, but with the 

 posterior border not as broad as the fore border of the second, and 

 without keel underneath ; all the segments bristle above and under 

 with silky white erect hairs, the first three are aciculate striolate, 

 the others are somewhat closely punctate ; legs long, very hairy, 

 hind tibiae with five spines outwardly. 



Length 6-| mm. ; width 1^ mm.

3 . Black, with a slight steel-blue tinge on the upper side, pro- 

 and mesonotuni, scutellum and tegulae ferruginous red; abdomen 

 sessile, third joint with a broad silky white band broadly i interrupted 

 in the centre ; body bristling with black hairs, which on the meta- 

 notum and the first basal abdominal segment are white. 



Head closely foveate, transverse, being nearly twice as broad as 

 long, the base straight and the angles quite sharp, equal in width to 

 the anterior border of the pronotum ; the eyes are large, deeply, 

 arcuately incised in the inner part, the space behind them long ; 

 antenna3 robust, the tubercles small, second joint very short, third 

 also short ; thorax almost parallel with the anterior border of the 

 pronotum straight, moderately angular and slightly narrower than 

 the apex of the metanotum, the suture carinate ; the somewhat 

 convex mesonotum bears no longitudinal groove ; the scutellum is 

 transverse, parallel, but with the apical angles horizontally dentate ; 

 the strongly declivous metanotum is sub-parallel laterally, being 

 slightly wider at the apex than at the base, and the hind angles are 

 distinctly aculeate ; it is broadly reticulate while the remainder of 

 the thorax is roughly foveate punctate, the tegulae are punctulate 

 and very hairy ; abdomen sessile, the first segment fitting against 

 the base of the second, the keel underneath is short and sharp, it is 

 closely and roughly punctured like the posterior part of the second 

 segment the anterior part of which is conspicuously foveate reticu- 

 late ; the other segments are roughly aciculate, the last one, how- 

 ever, is nearly strigillate punctate without any pygidial area ; spurs 

 of the tibite deeply fuscous ; wings fuscous, slightly steel-blue in 

 the fore part, stigma very small, sub-quadrate, radial cell long, trun- 

 cate at tip, two closed cubitals, the third one only partly closed at the
