mainder transverse, the ends darkened, thorax polished, 

 finely, sparsely punctate, becoming coarse and thick on the 

 apex of the hump, which is strongly raised and sharply 

 declivous and deeply cleft by the median sulcus. The apex 

 is thrown forward so as to project beyond the head, and 

 compressed, forming on each side a smooth, thin, sharp 

 divergent fan-shaped edge. The margin of the sulcus to the 

 rear shows as strongly raised into a supplemental ridge, 

 which gradually disappears on the sides. The rear edge 

 shows two small tubercles in front of the scutel, lateral 

 tubercle not very prominent. The elytral punctures are 

 sparse and fine in front, coarser behind. The elytral lines 

 are strongly raised, leaving deep pits in the intervals, the 

 sutural, median and humeral unite in forming a rather thick 

 elevation about the middle. These lines are continued to 

 the truncation and end in two strong tubercles placed on 

 either side of the middle of the edge of the truncation, the 

 pygidium shows a broad smooth line, carinate behind, deeply 

 longitudinally foveate, on either side at the bottom, the sides 

 of the abdomen and body are somewhat brown next the 

 elytra, remainder opaque black, legs brown, thighs darker.

 uniform brassy bronze with labrum and antennae ? (broken type) 

 joints 2-11 dark fulvous, thoracic hump very moderate, rounded de- 

 clivous behind and like cistella closely and rather rugosely punctate at 

 apex, median sulcus hardly visible anteriorly, very moderate behind ; 

 elytra sparsely punctate, becoming reticulate at rear, the sutural costa 

 plain as far as middle, the humeral faintly traceable to apex, the 

 others difficult to trace and more or less broken ; pygidium sparsely 

 finely punctate, faintly quadrately impressed, median carina fine, under 

 side and legs tinged with dusky, prosternum (viewed from front) 

 drawn gradually to a fine point at posterior two-thirds : length Z\
