these generally vary with the sex they furnish less reliable specific 

 characters. 



A. Hind claws strongly " bifid," — i.e.^ having the apex of the 



basal piece produced in a conspicuous process more than 

 half as large as the whole of the apical piece — hreviceps^ 

 Tugosipennis, soliduSj Beltance^ corpulentus, holosericeus, 

 piceoniger. 



B. Hind claws bifid (as above), but only minutely and at the apex 



— variegatus and Darlingensis. 



C. Hind claws " appendiculate," — i.e., having at the inner apex 



of the basal piece a free projection less than half as large 

 as the apical piece. 



a. The appendiculation minute and close to the apex of the 



claw — ceqioalis, testaceus, satelles. 



b. The apical piece fully as long as the basal piece — Froggatti. 



c. The appendiculation normal — i.e., the basal piece a little 



longer than the apical and with its apical process more 

 or less feeble — piceus, Jiorridus, gracilipes, Victorisy 

 occidentalis, puhescens, Randalli. 



H. PICEONIGER, Macl. 



Since the publication of Part I. of the " Revision " I have 

 received from Dr. Bovill examples of a JELeteronyx which agrees 

 very well with the description of //. piceoniger, Macl. Mr. 

 Froggatt of Sydney has done me the favour of comparing a speci- 

 men with the type and considers it the same species. In my 

 tabulation (Proc. L.S.N.S.W. 1888, pp. 1328-31) it would fall 

 side by side with R. corpidentus* (HH. p. 1331) from which it 

 may be at once distinguished by the exceptionally coarse and 

 sparse puncturation of its head. 



* It should be noted however that the erect hairs on the elytra are 

 scarcely to be called " long " (vic^e " GG." line 14, p. 1331) in R. piceoniger.
