forming (viewed from above) feeble obtuse angles with the base, 

 which is scarcely bisinuate and but feebly lobed hindward all 

 across. The puncturation of the elytra scarcely differs from that 

 of . the protborax except in being a little squamose ; the trans- 

 verse wrinkling is well defined, the lateral fiinge normal, the 

 apical membrane well defined. The general puncturation re- 

 sembles that of H. auricomus, but with the transverse wrinkling 

 of the elytra much more conspicuous. The under surface and 

 legs do not appear to differ noticeably from the same parts in 

 H. auricoimis except in the hind coxse being a little narrower, 

 and the uppermost external tooth on the front tibias considerably 

 smaller ; the external outline of the anterior tibia from its base 

 to the apex of the uppermost tooth is almost quite straight in 

 this species, while in //. auricomus it is quite strongly concave. 

 Port Lincoln ; not rare. 



N.B. — Some smaller specimens (long. 34 lines) — also from 

 Port Lincoln — are of a pale testaceous colour and seem to have 

 the prothorax slightly more sparsely punctured, but I am not 

 satisfied of their specitic distinctness. They have the same slight 

 but decided peculiarity in the nearly straight sides of the clypeus, 

 giving the Lead in front of the eyes (from some points of view) 

 something of the appearance of the sides presenting two truncate 

 faces.
