at the base of the claws. The unique species has elytra 

 nitid, glabrous, and strongly striate. 



EUEYCHELUS. 



1 doubt whether this genus can be permanently retained 

 as distinct from Heteronyx. There does not appear to me 

 to be any better character for it than its depressed parallel 

 form and the occurrence on its elytra of a fairly distinct 

 pattern, due to the presence of small patches of whitish 

 pubescence, the derm beneath the patches being also usually 

 of a lighter colour than the general surface. Regarded as a 

 Heteronyx the described species (E. marinoratus, Blanch.) 

 finds its place in the 1st Group (vide my tabulation, to fol- 

 low), and it stands next to H. Bovilli, Blackb., differing 

 from it inter alia multa by the very much closer punctura- 

 tion of its dorsal surface. I have examined a large number 

 of specimens of Eurychelus from various localities in New 

 South Wales and Victoria (all of them, I believe, in moun- 

 tainous regions), and am unable to regard them as repre- 

 senting more than one species, which, however, seems to be 

 variable in several respects, especially size (long., 3|-5J 1.) 

 and colouring, the usual colour being ferruginous marbled 

 with slightly lighter patches bearing short whitish hairs. In 

 many specimens the disc of the pronotum is blackish. In the 

 most highly coloured example before me the elytra are 

 piceous, with most of the suture as well as the paler blotches 

 very conspicuously testaceous, and the legs bright ferru- 

 ginous. Some examples from Mount Kosciusko (sent by Mr. 

 Carter) are darker than the usual type — one of them with 

 black elytra — and the marbling of the elytra is more or less 

 obsolete. The sculpture scarcely varies — only, I think, to 

 the extent of the pronotum being a little less closely punc- 

 tured in some specimens than others, but the varieties are 

 found in company with each other, and are very likely to be 

 the sexes. 



Anacheirotus. 



I have not seen any more species or specimens of this 

 genus since I characterized it eight years ago. It is. probably 

 found only in the dry central regions of Australia which are 

 seldom visited by entomologists. The validity of the genus 

 will probably stand permanently, for it is scarcely likely 

 that intermediate forms will be found linking the small in- 

 conspicuous labrum of Anacheirotus with the large prominent 

 labrum of a typical Heteronyx. 



Heteronyx. 

 This genus might reasonably claim to be the most per- 

 plexing to the student in the whole range of the Australian
