(and consequently more distinct) than in any of the common 

 species hitherto described in this monograph. It is most like that 

 of H, testaceus except in being very much less close The hind 

 coxae are scarcely so wide as the second ventral segment and very 

 much shorter than the metasternum. The sculpture and pubes- 

 cence of the under surface scarcely differ from those of the 

 preceding species {H. jej units). The hind femora are decidedly 

 wider than the intermediate, with their inner apical angle rather 

 prominent but a good deal rounded off. The lower two teeth of 

 the anterior tibige are unusually long and slender, the uppermost 

 sharp but small (less than half the size of the second).

Sat eiongatus ; sat convexus ; pone medium leviter dilatatus ; 

 sat nitidus ; piceo-ferrugineus, antennis palpisque dilutioribus ; 

 vix pubescens ; clypeo crebre rugulose, capite postice sparsim 

 subtiliter, prothorace minus sparsim minus subtiliter (huic angulis 

 posticis subrectis), elytris confuse subsquamose sat crebre, pygidio 

 (hoc longitudinaliter subcarinato) fortius crebrius, punctulatis ; 

 tibiariim anticarum dentibus externis perlongis ; labro clypeum 

 latissime minus fortiter superanti ; antennis 8-articulatis ; ungui-

Clypeus gently emarginate in front, its reflexed margin scarcely 

 indicated in the middle part ; owing to the slight convexity of 

 the upper outline of the labrum the appearance of a " trilobed 

 outline " of the head is only obscurely attainable from a point of 

 view far back and almost level with the surface of the head. The 

 clypeus does not quite form an even surface with the rest of the 

 head ; the clypeal suture is well impressed and nearly straight. 

 The prothorax does not differ from that of the preceding except 

 in its puncturation being a little less fine, and indeed in all other 

 respects the description of H. dentijyes may be taken as applying 

 to this species with the following qualifications, viz., the sculpture
