(J. MacUuyl, Blackb. I have received from Mr. R. C. L. 

 Perkins a number of specimens from North Queensland, which 

 1 cannot venture definitely to pronounce specifically distinct 

 from 0. Macltayl, although they present some differences. 

 They are of darker colour (dark piceous), with the apex and 

 the hinder part of the lateral margins of the elytra red. This 

 colouring points to the probability that the unique type of 

 0. Macleayi is immature, its colour being dark red brown, 

 with a traceable indication of still lighter colouring of the 

 sides and apex of the elytra. The eyes are a little less dis- 

 tinctly granulate in the type (which again may result from 

 immaturity), so that these recently acquired specimens do not 

 fall so evidently as the type into the aggregate cliaracterized 

 in my tabulation (Tr.R.S.S.A., 1903, p^ 270) as having the 

 eyes '"scarcely visibly facetted on their surface," although they 

 certainly could not be referred to the other aggregate (of 

 species having the eyes ''conspicuously facetted"). On the 

 whole, I believe them to be 0. Macleayi. Among the Queens- 

 land specimens there is one male- all the rest (and also, con- 

 trary to my previous opinion, the type, assuming identity") 

 being females. The male ]3rothorax is much more massive 

 than the female, with its front strongly and vertically decliv- 

 ous, the slight protuberances of the female notably exagge- 

 rated, and the puncturation of the dorsal surface finer and 

 less close. The male clypeus is more elongated and narrowed 

 in front, with its front almost evenly rounded. The sexual 

 difference of the front tibice is almost nil. The Queensland 

 specimens vary considerably in size (long.. 3-4 1.), and in some 

 of them the pronotum has a slight coppery gloss. The head 

 of the male is unarmed. 



0. hipunfiilatvs, Fab. By some oversight I misplaoed this 

 species in tabulating the Onthopliagi of Australia 

 (Tr.R.S.S.A., 1903). I placed it among the species having the 

 base of the pronotum without any raised or depressed mar-
