Qj.. 12 mm. Head black, thorax black or blackish brown above, 

 the lateral margins of the pronotum, the mesopleura, the lower half 

 of the epinotum and the lower third of its declivity ochreous, scale 

 ochreous or brownish ochreous, abdomen black, with dull ochreous 

 spots on each side disposed as follows: 1st segment, on the basal 

 half or two-thirds an elongate and not very sharply defined pair of 

 spots which are usually confluent at the base: 2nd segment, a pair 

 of round spots, rarely extending beyond the basal half of the segment: 

 3rd segment, a pair of much smaller spots of a dark brownish ochreous 

 colour with diffuse margins. Femora and coxae ochreous, tibiae and 

 tarsi blackish brown. Scapes black, flagellum testaceous and becoming 

 darker or brownish towards the apex. The extreme apical margins 

 of the abdominal segments testaceous. Head and thorax dull, abdomen 

 moderately shining. A few erect, brownish yellow pilose hairs arising 

 from shallow pits, on the head, pronotum and apical margins of the 

 abdominal segments; on the brow of the epinotum and edge of the 

 scale some similar but black hairs. A few short and yellowish hairs 

 on the anterior margin of the clypeus. Sides of the head, legs and 

 scapes with a sparse, short and adjacent pubescence, the flagellum 

 with a more abundant but finer pubescence. Head very finely and 

 closely reticulate, with a few small and very shallow punctures scattered 

 over the clypeus and the front of the cheeks. Thorax and abdomen 

 very finely rugulose. 



Head as long as wide, narrowed in front, the sides convex and 

 converging anteriorly, the hind margin distinctly concave, the post- 

 erior angles rounded. Median area of clypeus produced into a rect- 

 angular lobe in front, projecting over the base of the closed mandibles. 

 Clypeus carinate, the carina not reaching the anterior margin which 

 is feebly crenulate. Mandibles dull, sparsely and finely punctured, 

 armed with 7 acute teeth. The scapes extend a little beyond the 

 hind margin of the head, all the joints of the flagellum much longer 

 than wide. Eyes feebly convex, placed in the middle of the sides. 

 Degree of convexity of thorax, L. = 3'/ 3 H. Pronotum nearly one 

 and a half times wider than long in the middle ; mesonotum slightly 

 wider than long, metanotum distinct and twice as wide as long. 

 Declivity of epinotum smooth and shining, otherwise not clearly
