12 facets. Clypeus more or less triangular, the anterior margin 

 convex. Mandibles edentate, less than half as long as the head ; their 

 external margins converge towards the apex, so that the rnandibles 

 form an isosceles triangle with a small space between them at the base. 

 First and 4th joints of the flagellum subequal, 2nd and 3rd about as 

 long as wide, 5th joint as long as the rest of the flagellum. Pronotum 

 wider than long, fairly convex in front and at the sides, the shoulders 

 subangular ; pro-mesonotal sutm*e faintly defined. The posterior half 

 of the mesonotum rather abruptly depressed ; meso-epinotal suture 

 thin but fairly distinct. Dorsum of epinotum a little longer than 

 wide, convex transversely and longitudinally over the basal half, 

 oblique and flat over the apical half. Epinotum and posterior half of 

 mesonotum finely submarginate. Epinotal teeth short, hardly longer 

 than their basal width, moderately divergent, directed obliquely 

 upwards. A narrow and transparent band margins each side of the 

 declivity, starting from the lower side of the teeth. The peduncle of 

 the petiole is much longer than the node ; the latter, seen from above, 

 a little longer than wide (not including the portion behind, which is 

 more or less hidden by spongy tissue), rounded in front and at the 

 sides, fairly flat above. Secoud node twice as wide as the 1st, trans- 

 versely oval, furnished below with a long perpendicular spine which is 

 hidden by spongy tissue. The latter is not plentiful. 



$. 31 mm. (hitherto undescri bed). Eyes larger than in the $, 

 occupying about one-fifth of the sides of the head. Ocelli small. 

 Shoulders of pronotum subangular, exposed above. Mesonotum higher 

 than the pronotum, the anterior margin narrowed in front and 

 angular, but with the apex of the angle somewhat rounded, as long as 

 it is wide across the tegulae. Scutellum semicircular, nearly half as 

 long as the mesonotum, much higher than the dorsum of the epinotum, 

 which is steep and wider than long. Epinotal teeth triangular, 

 shorter than in the $ . Sides of mesothorax smooth and shining. 

 Dorsum of epinotum shorter than the declivity. Peduncle of the 

 petiole twice as long as the node ; the latter, seen from above, trans- 

 versely rectangular, twice as wide as long. Second node transversely 

 oval, two-thirds wider than long, one-third wider than the 1st. The 

 spongy tissue occurs as a narrow band on the lower surface of the 

 peduncle and also surrounds the 2nd node behind and below. Basal 

 third of the abdomen strongly and longitudinally striate. Otherwise 

 like the $ . Deiilated.
