scanty, composed of pale, erect, arid thick hairs, absent from the legs 

 and antennae, which have only a short, decumbent and yellowish 

 pubescence. Body without pubescence. 



Head longitudinally and strongly rugose between the frontal 

 carinae, the rugae connected by a few transverse branches, the sides 

 of the head more distinctly reticulate, the spaces between the rugae 

 fairly smooth and shining ; scrobes finely reticulate-punctate. Clypeus 

 tricarinate, the median carina the strongest. Thorax very coarsely 

 reticulate-rugose, the meshes wide, and the spaces between the 

 reticulations shining. The sides of the pi'onotum smooth and 

 shining, the sides of the meso- and epinotum more or less longi- 

 tudinally rugose, but finer than on the dorsum. Between the 

 epinotal spines there are a few transverse striae ; the declivity, 

 nodes, and abdomen smooth and shining. Head hardly longer than 

 wide, a little narrower in front than behind, the posterior margin 

 straight, the sides almost so, the posterior angles moderately rounded. 

 Eyes moderately convex and large, placed in the middle of the sides. 

 Frontal carinae prolonged back almost to the occipital margin, and 

 forming below distinct demiscrobes for the scapes. The latter as 

 long as the demiscrobes, the 2nd-8th joints of the flagellum much 

 wider than long. Mandibles shining, sparsely and finely punctured, 

 6-dentate, the posterior 4 teeth small and indistinct. Thorax mar- 

 ginate, moderately constricted between the pro- and mesonotum, 

 strongly so between the meso- and epinotum. Pro-mesonotal suture 

 nearly obsolete above, meso-epiuotal broad and shallow. Shoulders 

 of pronotum subjugular. Pronotum nearly as wide behind as in 

 front, sloping fairly steeply downwards. Dorsum of epinotum about 

 as long as wide, widened angularly near the base ; epinotal teeth 

 divergent, directed obliquely upwards, acute, as long as, or a little 

 longer than, the interval between their bases ; the declivity vertical, 

 the episterual teeth small, acute, 'and triangular. First node of 

 petiole squamiform, inclined slightly forwards, the lateral and dorsal 

 edges trenchant, the anterior face convex transversely, the posterior 

 face feebly convex. The peduncle is nearly as long as the node. 

 Second node twice as wide as long, wider than the 1st, the anterior 

 and posterior faces steep and convex transversely, and meeting 

 angularly at the sides. Abdomen smooth and shining, convex, the 

 1st segment funning almost the whole of 'the dorsum. All the femora 

 moderately swollen. 



9 . 3 - 6 mm. Like the ^ , but the thorax somewhat paler, more 

 reddish. Mesonotum and scutellum fairly closely and longitudinally 

 striate. Pronotum exposed above only at the shoulders. Dorsum of
