 the pronotum, transversely oval, the ineso-nietanotal suture visible 

 but not well marked, transverse ; metanotum a little depressed, 

 the basal portion about twice as broad as long, the sides denticulate 

 and prolonged posteriorly into long laminate spines pointing back- 

 wards and curved a little upwards ; legs stout and short, more 

 thickly studded than the body with short stout white bristles. 

 Pedicel short, the nodes not petiolate, thick, nearly subequal in 

 length ; the 1st truncate anteriorly, about half as broad again 

 as long ; 2nd truncate in front, rounded posteriorly and slightly 

 compressed, broader than long ; abdomen cordate, convex above, 

 emarginate anteriorly.

 thorax are coarsely rugose striate, the pedicel irregularly coarsely 

 granulate ; abdomen finely longitudinally striate, oval, longer and 

 more massive. Head broader posteriorly than in front, widely 

 but slightly emai'ginate ; mandibles punctured, irregularly striate ; 

 clypeus triangular, the suture posteriorly better defined than in

 of the head and of the thorax as well, with fewer projecting blunt 

 points. Thorax : the pronotum large, forming a part of the 

 dorsurn ; the anterior angles irregularly rounded ; mesonoturn 

 triangular, with the angles more or less rounded ; scutellum 

 transversely oval ; postscutellum transverse ; metanotum or 

 median segment large, the basal portion armed with two stout, 

 somewhat flat obtuse spines, the apical portion truncate, concave, 

 irregularly transversely striate. Pedicel with the nodes large,

 the tibiae and lower part of the tarsi of the legs reddish brown. 

 Head, thorax and abdomen coarsely rugose, granulate, irregularly 

 longitudinally striate reticulate, the margins of the head and 

 thorax irregularly crenulate or denticulate ; the granulate appear- 

 ance on the upper surface due to small acute tubercles, which, on 

 the margins of the head and thorax and on the abdomen, are 

 studded with very short bristly white hairs; the striae on the 

 abdomen finer than those on the head and thorax ; the abdomen 

 often has a silky, somewhat shining appearance. Head nearly 

 square, as broad posteriorly as long (or a little broader), and 

 narrowing a little towards the front, convex ; mandibles stout, 

 striate. with a smooth shining subapical line along the masticatory 

 margin; clypeus triangular, anteriorly depressed, the anterior 

 border medially emarginate, the posterior margins not distinctly
