Head very little wider behind than in front, as long as wide. 

 Eyes very convex and prominent, placed a little behind the middle of 

 the sides. Clypeus subtriangular, wider behind than in front, the 

 anterior margin slightly convex, the posterior margin not clearly 

 defined. Mandibles longitudinally and sharply striate, armed with 

 5 small teeth, the apical tooth subacute and larger than the rest. 

 Antennal scrobes smooth and shining, extending back almost to the 

 posterior angles of the head. Scapes dilated in the apical half, as 

 long as flagellum less the apical joint. First joint of flagellum as 

 long as wide, 3rd-5th joints wider than long. The anterior margin 

 of the pro-mesonotal disc convex, produced at the anterior corners 

 into a sharp angle on each side ; on each side, in the middle, the 

 margin of the disc is semicircularly and rather abruptly excised, and 

 in front and behind this excision the margin is slightly concave. 

 The posterior angles of the disc are produced into 2 small acute 

 teeth, which are a little longer than they are wide at the base. 

 Between the lateral teeth the posterior margin also bears 2 smaller 

 triangular teeth. The epinotuin is margined laterally and pix>duced 

 on each side into a sharp spine, which is at least twice as long as it is 

 wide at the base. First node of the petiole cuneiform, almost linear 

 above, as wide at the base as it is high, the anterior face vertical ; 

 2nd node globose, as wide as the 1st. Sides of the thorax and 

 epiuotum transversely and sparsely rugose.

£' . 27-4'2 mm. Black; tarsi and antennae more or less brownish- 

 black. Head and' thorax subopaque, nodes and abdomen dull, legs 

 slightly shining. Pilosity abundant and woolly, composed of fairly 

 long whitish hairs, erect on the body, oblique, less dense and shorter 

 on the legs and scapes. Flagellum moderately pubescent. Head, 

 thorax, and nodes coarsely reticulate-rugose, the spaces between the 

 reticulations slightly shining and roughened ; the rugae more or 

 less longitudinal on the head, on the nodes finer and closer. The 

 abdomen is ver;y closely and fairly finely reticulate-punctate. Epinotum 

 shallowly rugulose and shining above, striate laterally between the 

 epinotal spines and the posterior margin of the mesonotum. Sides 

 of thorax irregularly and shallowly rugose. 



Head, excluding the mandibles, as long as wide behind, narrowed
