than those of the interstices, antennae of pale-ferruginous colour, 

 elytral margins pale-ferruginous and the interstices granulous or 

 rugulose, upper surface set with short coarse pale setas, size very- 

 small. The prothorax to a casual glance looks longer than wide 

 but by measurement the length down the middle line is slightly 

 less than the greatest width. The nearest allies of this species 

 are, I think, L. duplex, Blackb., and Victories, Cand., from both 

 which it differs inter alia by its colour and the strong rugulosity 

 of its elytral interstices.

ENNOMETES. 



E. (Callirrhipis) ruficoniis, Gray. Some years ago I took, in 

 the Blue Mountain district of N.S.W., a species which seems to 

 be the very briefly described Callirrhipis ru/icornis, Gray. It is 

 however quite clearly a member of Pascoe's genus Ennometes 

 (which seems to me worthy of being considered really distinct 

 from Callirrhipis). I can find no character to distinguish as 

 species E. Eacordairei, Pasc, and C. ruficornis, Gray, nor does 

 the insect before me differ from either description except in being 

 somewhat larger than the specimen described by Pascoe (Gray 

 does not mention the size of his species). As Pascoe makes no 

 reference to C. rujicornis it seems not unlikely that he overlooked 

 it, and I suspect that Callirrhipis ruficomis and Ennometes 

 Lacordairei are identical, in which case the insect must stand as 

 Ennometes ruficomis, Gray. 



RHIPIDOCERA. 



H. mystacina, Fab. Mr. Waterhouse (Tr. E.S., Lond., 1875, 

 p. 202) describes the typical specimen of this insect and mentions 

 that examples from Northern Queensland are quite identical with 

 it. He then mentions what he calls the " common form" which 

 he says has the prothorax spotted (not evenly clothed) with 

 white pubescence as being in his opinion a variety of mystacina. 

 I have before me specimens of typical mystacina from N. Queens- 

 land and also examples with spotted prothorax from Tasmania, 

 Victoria, and S. Australia. These do not appear to differ inter se 

 except in the Tasmanian specimens being larger than those from 

 the mainland. They are decidedly R. femoralis, Kirby (which was 

 described from a small island close to Tasmania) and are certainly 

 a good species differing from mystacina (apart from the vestiture 

 of the prothorax) by inter alia the darker colour of their derm 

 and the notable sinuation of the sides of their prothorax (the 

 same in mystacina being nearly straight).
