524 REVISION OF THE AUSTRALIAN SPECIES OF BOLBOCERAS, 



ADDITIONAL NOTE. 



The following names are those of the described Australian 

 species of ]5olboceras not discussed or tabulated in the preceding 

 pages. The insects are not known to me, and the descriptions 

 of them do not furnish the particulars required for placing them 

 in a tabulation : — 



B. CAPREOLUS, Westw. 



Presumably a member of the Second Subgroup of my Second 

 Group. A very conspicuous species (from W. Australia), its 

 male having a cephalic horn, the apex of which is divided into 

 six projections. 



B. LACUNOSUM, Macl. 



(From Sydney). Probably a member of my Second Group, 

 but it seems doubtful in which Subgroup it should be placed. My 

 conjecture is that its nearest ally is B. Richardsce, Blackb., from 

 which it differs, inter alia, by there being no projection on the 

 head of the male. 



B. TRiTUBERCULATUM, Bainb. 



This species also seems to fall in my Second Group, and pro- 

 bably in the Second Subgroup. It is from W, Australia. Its 

 male is described and figured as having three large tubercles 

 placed triangularly in the centre of the retuse area of its prono- 

 tum. 



B. SwEERi, Macl. 



A small species appertaining to my Third Group. It might be 

 any one of numerous species that I have described, and could not 

 be identified without examination of the type. It is from Sweer's 

 Island. 



B. CORNICULATUM, Westw. 



Evidently a very remarkable and isolated species. I cannot 

 place it in any Group. It is of very small size (long, 3 lines), with 

 (in the male) two horns on the head and two on the pronotum. 

 Its habitat is W. Australia.
