Scape of antenna fairly long, extending bast well beyond the occipital 

 margin ; all the joints of the flagellum much longer than wide, the 

 2nd and apical joints longest. Pro-mesonotal suture faintly indicated. 

 Pronotum with strong transverse and oblique rugae, those on the 

 margius of the dorsum very distinct ; the ventral anterior angles pro- 

 duced into strong teeth. The mesonotum is raised posteriorly, and 

 has a very steep posterior face, the sides of which are sharply margined 

 and slightly expanded, or ear-shaped. The dorsum of the epinotum is 

 distinctly margined (the rugae which form the margius being con- 

 tinued along the outer sides of the spines), and is sublobate on each 

 side at the base, narrowed towards the apex. The spines are acute, 

 as long as the dorsum, slightly divergent apically, directed slightly 

 upwards. The declivity of the epinotum is very steep ; as long as, or 

 a little longer than, the dorsum ; distinctly margined laterally, the 

 margins being coutinued along the lower sides of the spines. Peduncle 

 of the 1st joint of the petiole flattened, one-quarter louger than the 

 node ; the latter more or less conical, as long as wide, somewhat com- 

 pressed laterally at the summit, the anterior face vertical and feebly 

 convex from above to below, the posterior face longer than the 

 anterior, and sloping downwards. The 2nd node about one-quarter 

 longer than wide ; widest at its posterior third. Seen from above, 

 the outline is subovate ; seen from the side, the anterior face is 

 convex, and slopes in a sharp curve forwards ; the posterior face is 

 shorter than the anterior, and vertical. The base of the abdomen 

 straight, with prominent but rounded lateral angles. The 1st segment 

 is about as wide as long, and much wider and longer than the remain- 

 ing segments taken together, which are hardly visible from above. 



$ . 14 mm. Pilosity and colour as in the ^ , but the colour is a 

 little darker, the sides of the mesonotum behind, and the middle 

 portion in front, dark brown. The hairs on the legs are more oblique 

 than in the £ . The sculpture is very similar to that of the ^ > but; is 

 stronger on the head, the region behind the eyes very coarsely reticu- 

 late, the space between the reticulations almost dull. Mesonotum and 

 scutellum strongly and fairly closely longitudinally striate, the pro- 

 notum with a few longitudinal and feeble striae. The epinotum is 

 very coarsely and longitudinally rugose on the dorsum, striate on the 

 sides, the median area of the declivity smooth. A narrow median area 

 on the anterior third of the mesonotum is without striae. A broad 

 transverse band on the apical margins of all the abdominal segments 

 subopaque and microscopically rugulose. The dorsum of the meso- 

 notum and scutellum is raised high above the level of the head and 

 epinotum. The mesonotum is very convex in front, lengthwise and
