BY THE REV. T. BLACKBURN. 155 



the middle lobe of the "trilobed outline" appears a little nar- 

 rower. The prothorax is about J again as wide as long, and the 

 base is in about the same proportion wider than the front, which 

 is deeply emarginate, with sharj:) prominent angles ; the sides are 

 nearly straight in their hinder half, thence converging arcuately 

 to the front (the segment is slightly at its widest a little in front 

 of, not at, the base), forming right angles (but somewhat rounded 

 off at extreme apex) with the base — as viewed from above — the 

 base being somewhat bisinuate and moderately lobed in the middle. 

 The elytra have little or no trace of striation, their transverse 

 wrinkling being fairly distinct, their lateral fringe normal, and 

 their membranous apex fairly defined. The general puncturation 

 of the upper surface resembles that of H. gracilijyes — the pro- 

 thorax being, however, rather less closely and less strongly, the 

 elytra decidedly more squamosely, punctured. A marked 

 character of the species is its decidedly close, not very short, 

 pale dirty brown pubescence, which is for the most part inclined 

 backward but not closely adpressed, with a good many erect 

 hairs rather longer than the rest. The hind femora are con- 

 siderably wider than the intermediate, their inner apical angle 

 well produced but not sharp. The hind coxse are only a little 

 shorter than the metasternum and very much longer than the 

 second ventral segment. The metasternum is rather strongly 

 punctured all across — more closely at the sides than in the 

 middle ; the hind coxaB much more sparingly especially on the 

 antero-internal region. The ventral segments are very distinctly 

 punctulate, more closely and strongly at the sides than in the 

 middle. The ventral series consist of long and rather fine hairs 

 and are well defined. The teeth of the anterior tibiae are very 

 robust, the uppermost being decidedly more than half the size of 

 the second tooth. 



Widely distributed in S. Australia but apparently not very 

 common.
