last joint of the palpi rather broadly securiform ; man- 

 dibles fissile at their extremity. Head rugged, sloping 

 from the vertex forward ; slightly contracted behind the 

 eyes, flattened or irregularly depressed above; epistome 

 gradually narrowing to the front, which is arcuately 

 emarginate, the angles scarcely rounded ; transversely 

 convex or thickened posteriorly, and separated from the 

 front by a sinuous furrow, from which start two obscurely 

 defined lateral ridges, directed behind; lahruvi trans- 

 verse, rounded at the sides, and arcuately notched in 

 front ; eyes transverse, gradually contracted inferiorly 

 by the cheeks, the superior portion sub-prominent. An- 

 tennce rather robust ; sub-perfoliate, finely setulose ; 

 second joint very short, third a little longer than the 

 following, obconic ; four to seven subequal, sub-obconic ; 

 eight to ten gradually broader, subglobose, pubescent ; 

 eleventh much larger, elongate-ovate, and densely clothed 

 with a very short, fine, decumbent pubescence. Pro- 

 thorax not contiguous to the elytra; subquadrate ; but 

 little convex ; slightly emarginate in front, subsinuous at 

 the base, which is very finely margined to about one- 

 fom-th its width on each side, the angles small but dis- 

 tinct ; but slightly rounded at the sides, which are finely 

 margined and obtusely crenulate. Scutelhim small, 

 triangular, placed on the scutum of the mesothorax. 

 Elytra oblong ; but little broader than the thorax at the 

 base ; subparallel, or very gradually widened to beyond 

 the middle, then contracted to the apex ; the lateral 

 margins becoming broader and more reflexed as they 

 approach the extremity ; humeral angles prominent, 

 somewhat reflexed, formed by an expansion of the epi- 

 pleural fold ; * the latter entire, sinuous before the 

 middle, but not at the extremity. Mcsosternum sloping-, 

 more or less concave in front; luetasternmn short; inter- 

 coxal process rather narrow and more or less rounded 

 anteriorly; the prosternal curved inwards, finely bi- 

 sulcate or margined. Le(/s moderate, somewhat robust ; 

 thighs of the anterior pair subclaviform, the posterior 

 rather strongly compressed ; fore and intermediate tibiae 

 straight, the hind subsinuous or not ; the apical half of 

 all rather densely clothed within with longish hairs ; 

 moderately spurred ; tarsi clothed beneath with long hairs ; 

 the penultimate joint of all entire, the first joint of the 

 posterior shorter than the last. Body elongate, wingless; 

 abdomen without pubescence.
