yellow. Head dull, closely reticulate -punctate, sparsely striate 

 between the frontal carinae and the ocelli. Mesonotum very sparsely 

 punctured, and with faint traces of a longitudinal striation on its 

 posterior half, otherwise smooth and shining. Scutellum dull, finely 

 longitudinally rugulose. Dorsum of the epinotum, the upper 

 two-thirds of the declivity, and the nodes finely reticulate ; the sides 

 of the epinotum faintly striate lengthwise. Abdomen smooth and 

 shining. 



Head widest in front, nearly as long as wide, the sides and hind 

 margin moderately convex, the posterior angles widely rounded. 

 Eyes fairly large, placed in the anterior third of the head, and 

 almost touching the base of the mandibles in front. The scapes 

 extend back as far as the posterior ocelli. Frontal carinae well 

 defined, widely divergent posteriorly. Mayrian furrows of the 

 mesonotum distinct ; mesonotum very convex and gibbous in front ; 

 scutellum semi-circular. Epinotum with two feeble lateral ridges at 

 the apical angles of the dorsum, the latter as long as the oblique 

 declivity. Episternal lobes large. Nodes thicker than in the ? ; 

 the peduncle of the 1st segment not distinctly defined (as is usually 

 the case in the <$ $ of this genus), merging insensibly into the 

 node.

" ^ . 3 - 5 mm. Red-brown, the mandibles, antennae and legs 

 paler, head and abdomen dark brown. The pilosity is most abundant 

 on the abdomen, and consists of partly pointed, partly blunt bristly 



hairs, Antennae and legs with a fairly abundant and 



oblique pubescence. Mandibles shining, smooth, sparsely and coarsely 

 punctured, and also very finely and shallowly striate, more densely 

 striate on the outer side near the base, armed usually with 7 teeth, 

 the anterior pair large, the others small and indistinct. Head 

 rectangular, the angles rounded, a little longer than wide, very little 

 narrower in front than behind, coarsely striate (the clypeus finely 

 striate), shining between the striae, partly smooth and partly 

 punctate or rugulose, the sides and back of the head coarsely 

 reticulate. Anterior margin of clypeus straight, without any 

 emargination. The frontal carinae, and the fairly deep demiscrobes, 

 extend back as far as the level of the eyes, the demiscrobes not 

 much longer than the scapes ; 3rd-6th joints of the flagellum
