— but somewhat evenly all across. The ventral series consist of 

 stout testaceous hairs and are conspicuous. The hind femora are 

 much wider than the intermediate and have their inner apical 

 angle well defined. The external teeth of the anterior tibiae are 

 strong and blunt, the uppermost very close to and about half as 

 large as the second. In the tabulation (P.L.S.N.S.W. 1889, 

 p. 144) this species would fall under "GG," though the punctur- 

 ation of the ventral segments is a little stronger than in H. 

 crassics, Augicstce, and Sloanei ; the hind angles of the prothorax 

 are as in H. Sloanei, from which the present species differs inter 

 alia by its much smaller head. 



Sent to me by Sir William Macleay as H. holomeloinus, Blanch., 

 but that species is especially stated to have 9-jointed antennae.

GROUP VI. 



H. POTENs, Blackb. 



Among a miscellaneous batch of specimens sent to me some 

 time ago by Mr. Sloane, — taken by him from flood refuse on the 

 banks of the Murray, — I find a specimen which I cannot separate 

 from H. potens ; it diff'ers, however, from all the numerous other 

 examples I have seen in having the hairs on its upper surface all 

 erect instead of recumbent. Whether the horrors of its situation 

 when it fell into Mr. Sloane's hands made its hair thus stand on 

 end I cannot say, but certainly it seems to possess no structural 

 character suggestive of its being a distinct species. 



The following species, — appertaining probably to my Section 

 III. of Heteronyx, — I have been unable to identify. All of 

 them except H. unicolor, Blanch., appear to have 9-jointed 

 antennae. The first 7 are from Tasmania, and very probable may 

 be confined to that island.
