garoo Island). Blanchard, unfortunately, does not describe 

 the claws of any of his Heteronyces. H. ruhescens, in my 

 former revision, was placed in the "intermediate" (now 

 abolished) main division of the genus, on account of its 

 labrum being slightly visible as part of the free outline of 

 the head, but appearing (when so seen) concave, and not 

 rising to the level of the clypeus. The following tabulation 

 shows the distinctive characters of the species of this group : — 



A. Lateral gutter of pronotiim distinctly 

 expanded and flattened out close to 

 front margin. 

 B. Hiud projection of hind claws much 

 smaller than the whole apical piece. 

 C. Hind projection of hind claws much 

 nearer to apex of claw than to 

 base of claw. 

 D. Elytra not or scarcely granulate. 

 E. Punctures of elytra well de- 

 fined and isolated. 

 F Elytral punctures somewhat 

 close (many more than 17 

 across an elytron). 

 G. Basal edging of pronotum 

 conspicuously thickened 

 and raised at its ends ... 

 GG. Basal edging of prono- 

 tum uniform or nearly so 

 FF. Elytral punctures very few 

 (about 17 across an elytron) 

 EE. Punctures of elytra indistinct 

 (in antero-lateral part lost in 

 subconfluent rugulosity) 

 DD. Elytra uniformly and con- 

 spicuously granulate 



CC. Hind projection of hind claws 

 scarcely nearer to apex of claw 



than to base of claw 



BB. Hind projection of hind claws not 

 or scarcely smaller than the whole 

 apical piece. 

 C. Middle part of summit of labrum 

 projects from perpendicular front 

 of clypeus. 

 D. Elytra non-striate outside sub- 

 sutural stria. 

 E. Elytra granulate. 



F. Prothorax very little nar- 

 rowed in front 



FF. Prothorax much narroAved 



in front 



E. Elytra not granulate 



DD. Elytra with 6 or 7 quite dis- 

 tinct strise 



CC. Middle part of summit of labrum 

 closely applied to perpendicular 



front of clypeus labralis, Blackh.
