Frontal carinae short and strongly divergent. Scapes short, extending 

 beyond the lateral margins by about twice their apical width. Eyes 

 small, placed a little in front of the anterior third. Mandibles stout, 

 very convex externally, smooth and shining. Clypeus feebly carinate, 

 shallowly emarginate in front. Posterior lateral angles of pronotum 

 very rounded and inconspicuous. Pro-mesonotal suture indicated 

 by a thin raised line. Scutellum fairly well defined, bituberculate. 

 Metanotum fairly distinct but short. Meta-epinotal suture rather 

 shallow. Dorsum of epinotum flat, submarginate at the sides, wider 

 than long ; epinotal spines subvertical, divergent, about two-thirds the 

 length of the space between their bases. Declivity of epinotum longer 

 than its dorsum. Dorsal face of the 1st node a little wider than long, the 

 dorsal edge shallowly emarginate. Second node, including the lateral 

 spines, three times wider than long; the spines are obtuse at the apex and 

 usually longer than their basal width, more or less curved backwards. 



5 . 3 mm. Piceous or black, legs and antennae as in the 1/ . The 

 pilosity and pubescence very scanty. Anterior half of the head, but 

 excluding the frons, reticulate and longitudinally striate ; the rest of 

 the head smooth and very shining. Meso- and epithorax and sides of 

 the 1st segment of the petiole reticulate and faintly shining, the rest 

 of the body smooth and shining. Head as long as wide, the sides 

 feebly convex, the hind margin straight. Clypeus carinate. Prontal 

 carinae parallel. Eyes placed in the middle of the sides. Mandibles 

 longitudinally striate. The scape extends back beyond the occipital 

 margin by about twice its apical width. Posterior lateral angles of 

 the pronotum distinct but small. Mesonotum with a moderately 

 deep transverse impression. Meso-epinotal suture deep. Dorsum of 

 epinotum margined at the sides, one and a-half times longer than 

 wide. Epinotal spines short, triangular, subvertical, hardly two-thirds 

 as long as the space between them. Dorsal edge of the 1st node 

 rounded, not trenchant ; 2nd node with the sides produced into strong- 

 conical teeth, the anterior margin strongly convex. 



$ . 62 mm. (hitherto undescribed) . Thorax, legs, antennae and 

 mandibles pale brownish-ochreous, head yellowish-brown, apex of 

 scutellum and greater part of the metanotum brownish, the mesonotum 

 with a median and tw T o smaller lateral longitudinal bands more darkly 

 coloured than the rest of the thorax, abdomen yellowdsh-brown. 

 Pilosity moderately abundant, yellowish, and not long, longest on the 

 back of the head and on the petiole. Head dull, very finely reticulate- 

 punctate, also finely striate between the eyes and the insertion of the 

 scape. Epinotum and nodes subopaque and finely rugulose, metanotum 

 transversely striate, the rest of the body smooth, shining, and nearly
