the strice being also common to the metasternum ; the tibiae 

 are dilated on the outer edge. 



This species resembles seminitens, Sch., in the punctuation 

 of the thorax and in the punctiform sutural stria.

Orbicular, convex, black and shining ; the head is some- 

 what opaque, being microscopically rugose, very slightly 

 impressed anteriorly, and without a frontal stria; the thorax, 

 stria feebly sinuous before the basal angles, anterior angles not 

 very prominent, less so than those of Lucasi, Mars., and foveo- 

 late at the base close to the outer margin ; the elytra, stride, 

 outer humeral dimidiate, inner complete, 1-2 dorsal basal and 

 very short ; the pygidia are finely and somewhat irregularly 

 punctured, the points being most distinct at the bases of tiie 

 segments ; the prosternum, surface opaque and microscopi- 

 cally rugose, with indistinct punctures on the anterior half of 

 the keel, stria rather fine, widely sinuous laterally and widening 

 out anteriorly somewhat similarly, but rather more, to those 

 of corpidentus. Lew. (see figure, Ann. & Mag. Nat. Hist. x. 

 pi. xix. fig. 1, 1892) ; the mesosternum, marginal stria is 

 very fine and the fovea shallow.
