rounded off so that the sides become the base without any indica- 

 tion whatever from any point of view of any exact point where 

 they do so ; the base of the prothorax is not bisinuate and is 

 evenly and strongly lobed hind ward all across; the puncturation of 

 the head and prothorax is scarcely coarser but a little less strongly 

 impressed than in H. juhatus ; the hind coxae are less coarsely 

 punctured ; the ventral series are probably more conspicuous (in 

 the example before me they are rubbed off and I judge only from 

 the punctures that have borne them). 



This is the insect which Sir William Macleay regards as H. 

 dimidiatus, Er., but the puncturation of the head is not consistent 

 with that determination ; moreover Erichson says of the prothorax 

 " angulis posterioribus obtusis," whereas in this species there are 

 no angles at all.

Minus elongatus; postice vix dilatatus; minus nitidus; pilis (an- 

 tice longis erectis, postice brevioribus adpressis) sat dense vestitus; 

 piceo-niger ; palpis, antennis, tarsi s, elytrisque, rufo-testaceis ; 

 capite 8equaliter rugulose sat crebre, prothorace et elytris confertim 

 subtiliter, pygidio obscure, punctulatis ; labro clypeum late sat 

 fortiter superanti ; antennis 9-articulatis ; unguiculis appendicu- 

 latis, unguiculorum posticorum parte basali apicali parum longiori; 

 coxis posticis metasterno haud brevioribus.

So closely allied to H. juhatus that the detailed description of 

 that species may be taken as referring to the present one with the 

 following qualifications ; — the labrum is more prominent, and the 

 sides of the clypeus are less reflexed and less produced forward so 

 that in the "trilobed outline" of the head there is a very slight 

 concavity between the lobes, and the appearance is rather that of 

 a continuous curve much more strongly convex in the middle than 

 at the sides, this more strongly convex piece (the middle lobe) 

 being much more than half as wide as the lateral lobes. The 

 puncturation of the upper surface is much finer and closer than in
