Varying from medium to a little above medium size, dark griseo-fus- 

 cous, often tinged more or less heavily with ferruginous. Head a little 

 prominent, olivaceo-testaceous freckled with fuscous, above more or less 

 jnfuscated, sometimes diffusing the whole, sometimes confined to two 

 divergent longitudinal stripes, with a broad, piceous, postocular band; 

 vertex rather tumid, somewhat elevated above the prouotum, the inter- 

 space between the eyes nearly twice as broad as the first antenna! joint 

 in both sexes; fastigium steeply declivent, shallowly sulcate, more shal- 

 lowly in the female than in the male; frontal costa rather prominent, 

 failing to reach the clypeus, feebly narrowed above especially in the 

 male, fully as broad as the interspace between the eyes, slightly sulcate 

 at and below the ocellus, irregularly punctate throughout, above more 

 densely and with a tendency to a biseriate arrangement; eyes moderate, 

 rather prominent particularly in the male, much longer than the infra- 

 ocular portion of the genae; antennae rufo- or luteo-testaceous, about 

 five-sixths (male) or three fifths (femal'e) as long as the hind femora. 

 Pronotum rather short, feebly and angularly constricted in the middle, 

 the broad angulation at the principal sulcus and produced mostly by 

 the posterior expansion of the metazoua, more or less iufuscated and 

 often also ferruginous above, the lateral lobes with a generally distinct 

 and entire but sometimes broken or maculate, broad, piceous, postocular 

 band, confined to the prozona ; disk broadly convex and passing into 

 the vertical lateral lobes somewhat abruptly but with a well-rounded 

 shoulder, simulating but nowhere really forming distinct lateral cariuae ; 

 median carina distinct and well marked on the metazoua, obscure and 

 generally subobsoleteon the prozouaif not indeed obsolete, particularly 

 between the sulci and in the female; front margin truncate but very 

 narrowly and minutely flaring, hind margin obtusangulate. the angle 

 very slightly rounded ; prozona subquadrate a little variable on either 

 side (male) or distinctly transverse (female), rarely and then feebly 

 longer than the densely punctate metazona. Prosternal spine variable, 

 usually short, conical, a little blunt, slightly appressed, erect (male) or
