impressions broad, shallow ; posterior marginal puncture in the 

 marginal channel at the basal angle. Elytra depressed, ovate, 

 hi-oader than pro thorax (15-5 x 9-8 mm.), widest a little behind 

 middle, widely rounded at apex ; sides lightly rounded, a little 

 narrowed to base ; apical curve short, obtuse, oblique (not 

 sinuate) on each side ; stria? finely punctate ; striole at base of 

 first interstice short, distinct ; interstices costate, first, third, 

 fifth and seventh strongly costate and much more elevated than 

 second, fourth and sixth, eighth flat, ninth obsolete anteriorly, 

 narrow posteriorly, punctate along the course of the deeply 

 impressed eighth stria, the punctures more closely placed 

 posteriorly ; lateral border lightly upturned ; marginal channel 

 wide ; third interstice with three widely placed pvxnctures on 

 apical half. Prosternum longitudinally impressed between coxae, 

 setigero-punctate on base. Metastei*num with a few strong 

 setigerous punctures on each side near posterior margin. Ventral 

 segments lightly impressed on each side, second with a few fine 

 setigerous punctures behind posterior coxae, third with a few 

 inconspicuous punctures on each side of middle, fourth and fifth 

 with a single setigerous puncture on each side of middle. 

 Posterior coxa? contiguous ; anterior tarsi with three basal joints 

 broadly dilatate and squamulose beneath. 



5. Not differing from ^, except in sexual characters, and in 

 having the sides of the prothorax apparently less sinuate towards 

 the base. 



Length 29, breadth 9-8 mm. 



I/ah. — Port Macquarie, N.S.W. (I took a single specimen (9) 

 at Port Macquarie in February, 1886 ; other specimens are in my 

 collection without exact locality). 



The affinity of this species is to //. renardi, Chaud., and H. 

 vigorsi, Gory, with both of which it agrees in all important 

 structural characters. Its smaller size prevents it from being 

 confused with //. renardi, while from B. vii/orsi, which is about 

 the same size, it may easily be distinguished by its broader and 

 more depressed form ; the prothorax sinuate on each side towards
