558 NOTES ON AUSTRALIAN COLEOPTERA, 



angles (but not very sharply so) with the base which is gently 

 bisinuate and but little lobed in the middle. The elytra scarcely 

 show a trace of even a sutural stria ; their transverse wrinkling is 

 well developed, their lateral fringe normal, their apical membrane 

 distinct. The puncturation of the upper surface resembles that 

 of E. constans, Blackb., but is markedly coarser throughout. The 

 hind femora are moderately wider than the intermediate, their 

 inner apical projection being well developed but quite widely 

 rounded. The hind coxae are considerably shorter than the 

 metasternum and 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 coxee still more 

 strongly, with the antero-internal region Isevigate, The ventral 

 segments are punctured pretty strongly and closely at the sides 

 but the puncturation is very feeble in the middle. The ventral 

 series consist of rather stout bristles and are not very conspicuous. 

 The teeth of the anterior tibiae are very long and robust, the 

 uppermost being somewhat more than half the size of the inter- 

 mediate. The apical piece of the hind claws is scarcely shorter 

 than the basal piece, of which the apical projection is very slight. 



In the tabulation (P.L.S.N.S.W., 1889, pp. 141, &c.), this 

 species wall take its place under "F" at the top of p. 143 in 

 company with II. nigellus and duhius from both of which it is 

 distinguished inter alia by its much larger size.

Heteronyx puncticollis, Blackb. 



I have received from Mr. Froggatt several specimens taken near 

 Sydney, which I refer with some doubt to this species ; theclypeal 

 suture is much less defined than in the Victorian type, the whole 

 surface of the head being almost an even plane, and the general 

 puncturation seems slightly closer and stronger, but they agree so 

 well in the unusual relative puncturation of prothorax and elytra, 

 and in the peculiar front tibise as well as in structural characters 

 generally that I cannot bring myself to separate them.
