The strong puncturation, especially of the petiole and 1st

" $ . 2-2 - 3 mm. Mandibles smooth, punctured, narrow, and with 

 terminal margin oblique. The insertion of each antenna lies in a 

 depression bounded externally by a lateral carina concave inwards, 

 internally by the frontal carina, and posteriorly by a transverse ridge 

 which joins the lateral and frontal carinae. Head rectangular, one 

 and a quarter times as long as wide, sides convex, as wide at the back 

 as in front, and with a lateral raised margin on each side of the 

 occiput. Eyes absent. 



Scape thick, hardly reaching the middle of the head ; 1st joint of 

 the flagellum broader than long, 2nd-6th joints twice as broad as 

 long, last joint slightly swollen and as long as the four preceding 

 joints together. 



Dorsum of thorax sub-depressed, faintly and obtusely marginate 

 and about three times as long as wide. Pronotum and epinotum of 

 about equal size ; mesonotum shorter and narrower ; declivity of 

 the epinotum sub-vertical, smooth, and marginate at the sides and 

 above. Petiole seen from above, almost square, corners rounded, as 

 long as wide. First segment of abdomen also almost square, one and 

 a half times as long and as wide as the petiole, and with apical margin 

 straight. The articular portions between the 1st and 2nd segments 

 form a stridulatory surface. The whole body and legs smooth and
