behind produced on each side into a prominent angle, which is slightly 

 obtuse at the apex ; it is Avidest between the angles and one-third 

 wider than long. Pro-mesonotal suture feeble. Seen in profile, the 

 pro-mesonotum is very convex, almost angular or rising from in front 

 to the pro-mesonotal suture, thence curving abruptly down to the base 

 of the mesonotum. The latter is subcircular, a little less than half as 

 wide as the pronotum between the posterior angles, and a little wider 

 than long. The metanotal region is not clearly defined. Dorsum of 

 epinotum horizontal, a little longer than wide; the declivity a little 

 longer than the dorsum, and oblique. Epinotal teeth small, not longer 

 than their basal width, directed backwards, upwards and slightly 

 outwards. First joint of the petiole about twice as long as wide, 

 seen from above triangular, the anterior face quite twice as long as 

 the posterior-dorsal, the dorsal edge {dorsal edge, see Text-fig. 20), 

 indented in the middle. Second node one-third wider than long, 

 narrowed behind, transversely lozenge-shaped, the sides produced 

 into subacute angles, the anterior face convex. Abdomen nearly 

 circular, the base truncate. All the femora swollen. 



£ . 2"7-3 mm. Head varying from light yellowish-brown to dark 

 brown with a slightly reddish tinge. Thorax and petiole varying 

 from ochreous to light yellowish-brown, abdomen light brown to 

 dark brown, the base of the 1st segment always somewhat paler ; 

 legs pale fuscous yellow, the tarsi lighter, the antennae brownish-yellow. 

 Head smooth and shining, with a few very shallow punctures. Pro- 

 and mesonotum shining, but less than the head, the mesonotum 

 faintly rugulose above, reticulate and dull at the sides. Epinotum 

 dull and reticulate. Petiole, abdomen and legs almost smooth, 

 slightly shining. 



Head subcircular, a little longer than wide. Eyes convex, placed 

 in the middle of the sides. Clypeus narrow at the sides, the median 

 area with a median longitudinal raised line (hardly a carina), the 

 anterior margin convex. Mandibles triangular, the masticatory 

 margin as long as the basal, finely denticulate, the two apical teeth 

 acute. Frontal carinae extending back to the level of the anterior 

 margin of the eyes, rather wide apart and divergent behind. Frontal 

 area triangular, depressed. Scape of the antennae long, incrassate 

 towards the apex, extending beyond the occipital margin by about 

 one-fifth of its length ; flagellum long, the 1st joint two and a-quarter 

 times longer than wide, all the other joints also longer than wide, the 

 3- jointed club a little longer than the rest of the flagellum. 



Pro-mesonotum less convex than in the 1/ , the dorsal profile forming 

 a longer and lower convexity, the curve of the mesonotum especially
