its own length ; flagellum filiform, all the joints much longer than 

 wide, 2nd joint two-thirds longer than the 1st. Mandibles shallowly 

 punctured and shining, slightly widening from the middle to the 

 apex, masticatory margin edentate and rather long. Pronotum 

 slightly longer than wide, rounded above, in front and at the sides. 

 Mesonotum rectangular, flat, longer than wide ; pro-mesonotal and 

 meso-epinotal sutures distinct. Dorsum of epinotum almost as long 

 as pro- and mesonotum together, very narrow at the base, widening 

 towards the brow of the declivity ; the latter is very sbort and has a 

 small angular projection above on each side. Node of petiole seen 

 from above, two and a third times as long as wide, widest bebind 

 and strongly compressed laterally ; seen from the side the node is 

 almost triangular, the posterior margin vertically truncate, the dorsal 

 profile from the base to the upper margin of the posterior face 

 convex. The posterior face is smooth and shining. Ventral lamella 

 angularly produced at the extreme base. The constriction between 

 the 1st and 2nd abdominal segments is not deep. First segment 

 campaniform, with a sharp angular projection at its base below, at 

 the junction with the petiole. Fourth and apical segments strongly 

 compressed laterally. Legs long and slender.

$ . 7 mm. (hitherto undescribed). Colour and pubescence as 

 in the £ , with the antennae entirely ferruginous. Whole body 

 shining, head with a few small punctures between the eyes and 

 antennal sockets, prothorax smooth and impunctate, mesonotum 

 with a few large shallow punctures, epinotum transversely striate. 

 Head a little longer than it is wide across the eyes. The latter 

 large, occupying more than half the sides of the head and separated 

 from the base of the mandibles by a distance equal to the length of 

 the 1st joint of the flagellum. Antennae filiform, reaching back as 

 far as the base of the 3rd abdominal segment ; scape three and a 

 quarter times as long as the 1st joint, 2nd joint of flagellum one and 

 a half times as long as the scape. Clypeus long, sub-carinate 

 medially, the anterior margin produced into a pronounced beak in 

 the middle. Mandibles ochreous, oblong, rounded at the apex and 

 edentate. Pronotum exposed, quite twice as wide as long ; meso- 

 notum a quarter longer than wide, the Mayrian furrows wide and 

 well defined. Epinotum as long as the mesonotum, longer than 

 wide, widest at the base and narrowing towards the apex, and three 

 times as long as the declivity. The latter is oblique, margined above 

 and at the sides, the margins produced at each side above into short 

 blunt angles. Node of the petiole as in the $ , but a trifle wider at
