■626 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



by nie must have contained at least 40 larvte, a number of which 

 were successfully reared. 



Many of the species are extremely variable in size, and the 

 colour of the derm and scales is subject to considerable variation, 

 and, owing to the usually large size of the scales and their feeble 

 juncture with the derm, they are very easil}^ abraded. In most 

 of the species there is a large pale oblit^ue patcli on each side of 

 the prothorax, which often resolves itself into two vittre conjoined 

 at base and reaching the apical tubercles (where there are any 

 such). The one-clawed tarsal joint is usually sufficiently distinct, 

 but in some species can only be traced with extreme difficulty. 

 Chevrolat has divided the genus into six sections, but it appears 

 to me that this is unnecessary, two (depending on the presence 

 or absence of fascicles; being sufficient. Most of the species have 

 .a seven-jointed funicle, but in three West Australian species I 

 have under examination it is but six-jointed. Pascoe has pro- 

 posed a genus (Aolles ) to receive two species having a six-jointed 

 funicle and trimerous tarsi; I am convinced that he was mistaken" 

 in regard to the tarsi, having very little doubt but that I have 

 his A. rahiginosus, which has a very small claw-joint traceable 

 only with difficulty (it is almost impossible to see it except with 

 the aid of a compound microscope) in the largely padded 3rd 

 joint, and antennae distinctly six-jointed; A. nuceus I do not 

 know, but the tarsi are probably similar in character. The femora 

 have usually a moderately large tooth, and a smaller one or thick 

 spine below it; in some species, however, there aj^pears to be but 

 one. Each side of apex of tibire is supplied with black setose 

 scales or spines, densest internally.
