near the base, much more sharply defined than in Peringueyi. 

 Scape of antenna cylindrical and reaching back beyond the occi- 

 pital margin ; 2nd joint of flagellum longer than the 1st. all the 

 joints long and cylindrical. Pronotum as long as wide, its dorsum 

 convex, sub-quadrangular, and margined behind and at the sides by 

 a raised line (more pronounced than in Peringueyi), which ter- 

 minates before the anterior margin. Pro-meso, and meso-metanotaL 

 sutures well defined, the latter more strongly so than in Peringueyi. 

 Dorsum of epinotum more compressed and much narrower than in 

 Peringueyi, the declivity is triangular but narrower, and its sides 

 are more sharply marginate than in that species. The declivity 

 above, at its junction with the dorsum, has a longitudinal depression,, 

 which is bounded on each side by the lateral margins. Node and 

 abdomen as in Peringueyi, but the abdomen is longer and narrower 

 in proportion, and the constriction between the 1st and 2nd segments 

 is entirely absent ; the 1st segment below, at its junction with the 

 petiole is also produced into a strong tooth, as in Peringueyi, but the 

 ventral lamella of the petiole is larger and less blunt at the apex 

 than in that species. Legs long and slender, with two calcaria fc> 

 the middle and hind legs, and the claws of the tarsi with a small tooth 

 near the middle. 



$ (hitherto undescribed). 12 mm. Black, legs brownish black 

 with the tarsi paler, mandibles ferruginous. Head and thorax very 

 finely punctured, but more densely so than in the £ ; the mesonotum 

 is almost reticulate-punctate, the epinotum shallowly rugulose, the 

 petiole impunctate, 1st abdominal segment very sparsely and finely 

 punctured, the remaining segments microscopically punctate. The 

 whole body pubescent as in the g , but the pubescence on the thorax 

 is very sparse. Head dull, thorax sub-nitidulous, abdomen very 

 shining. Head wider across the eyes than it is long, considerably 

 contracted in front of the eyes. The latter large, occupying about 

 one -third of the sides of the head, the internal margins feebly sinuate. 

 Ocelli large, situate on a raised area. Glypeus very convex from 

 side to side and rather long (as long as the scape), the anterior 

 margin almost straight. Mandibles oblong, very small, hardly 

 meeting together when closed, edentate. Frontal carinae obsolete. 

 Antennae very long, reaching back almost to the apex of the abdomen, 

 scape half as long as the 3rd joint of the flagellum ; the 1st joint of 

 the latter is very short, being less than half as long as the scape, 

 the 2nd joint a little longer than the 3rd, all the joints except the 

 1st long and cylindrical. Pronotum only slightly exposed, meso- 

 notum as long as wide, raised, round in front and convex from side
