minus fortiter superanti ; antennis 8-articulatis ; ungiiiculis appen- 

 diciilatis ; coxis posticis abdominis segmento ventrali 2° haud 

 longioribus. [Long. 3i lat. If lines. 



Clypeus feebly and widely emarginate in front, its reflexed 

 margin not quite obsolete even in the middle ; " triloVjed outline " 

 of head very feebly visible from any point of view, the lobes 

 appearing when viewed from the most favourable position to be 

 scarcely developed, with the middle one very little narrower than 

 the external ones ; clypeus not continuous with the rest of the 

 head; clypeal suture strongly marked and undulating. Prothorax a 

 little less than twice as wide as long ; its base about I again as wide 

 as its front, which is moderately emarginate with fairly prominent 

 sharp angles ; its sides moderately curved, most divergent near the 

 base ; its hind angles (viewed from above) much rounded ofi' and 

 not in the least directed hindward ; its base scarcely bisinuate and 

 moderately lobed backward all across. Elytra with scarcely a 

 trace even of a sutural stria; their transverse wrinkling fine and 

 inconspicuous ; their lateral fringe normal ; their membranous apex 

 obscure. The sculpture of the upper surface is evidently coarser 

 and more sparing than of H. testaceus, to which insect this species 

 bears a close superficial resemblance. The hind coxae are of the 

 same length as the second ventral segment, being very much 

 shorter than the metasternum which is closely and moderately 

 strongly punctured at the sides, feebly and sparingly in the middle, 

 — the hind coxae being nearly impunctate, except the sparingly and 

 coarsely punctulate lateral and hinder portions. The ventral 

 segments are coarsely but not closely punctured, — much more 

 feebly in the middle. The ventral series consist of fine hairs and 

 are little conspicuous. The hind femora are but little wider than 

 the intermediate, with their inner apical angle neither sharp nor 

 very prominent. All the teeth of the anterior tibiae are sharp 

 and fairly large, — the uppermost scarcely half the size of the 

 second.
