This species, altliough common and widely distributed in South 

 Australia, seems to have escaped receiving a name hitherto. In 

 a long series before me I find an invariable character in the brown 

 or pitchy tone of the upper surface, the green or brassy tint 

 always appearing as a kind of gloss or polish quite distinct from 

 the real colour. The colour of the undersurface varies from 

 brownish testaceous (probably in immature examples only) to dark 

 pitchy. In some examples the antennae are a little infuscate, but 

 I do not find any variation in the colour of the legs. The pro- 

 thorax is rather more than half again as wide as long ; it is 

 obscurely punctured immediately within the lateral margin and 

 more distinctly in and about the basal fovese ; its hind angles 

 though much rounded ofi" are quite distinct. The elytra at their 

 base are considerably wider than the base of the prothorax ; their 

 abbre"\dated sutural stria is variable but never either non-existent 

 or very strongly marked. The hind trochanters are about half as 

 long as the hind femora ; they are nearly straight and are blunt 

 at the apex. 



The present insect is near H. inornatus, Germ., from which it 

 difiers (apart from colour) by the much more strongly rounded 

 sides of the prothorax, and the very much less strongly dilated 

 tarsi of the male ; it is much like II. Deyrollei, Cast., in colour, — 

 but the latter species has shorter antennae, prothorax devoid of 

 puncturation and with hind angles quite rounded ofi", feebler
