long-based Y; another male, taken with them, has the process represented by a 

 feeble node only. 



ONTHOPHAGUS PRONUS Er. 



Plate vii, %. 27. 



This species varies considerably in size. On some males the prothoracic 

 horn projects beyond the head, on others it terminates short of the clypens. 



ONTHOPHAGUS TWEEDENSIS Blackb. 



Plate viii, figs. 48, 49. 



Of three males of this species before me (from Stradbroke Island) each has 

 the elevation between the cephalic horns trilobed and the suture greenish. The 

 female (three from Stradbroke Island and one from Bribie Island) differs from 

 the male in having denser and coarser punctures on the head, no horns between 

 the eyes, but a feeble ridge curved backwards, the prothorax with coarser ]iunc- 

 tures and scarcely refuse in front, and the front tibiae shorter, with stouter teeth. 



ONTHOPHAGUS HENLEYENSIS Blackb. 



A specimen from Yilgarn, unfortunately without antennae or tarsi, possibly 

 belongs to this species, but differs from some typical specimens in having the 

 prothorax conspicuously greenish, less convex, with smaller punctures and a 

 distinct medio-apical depression. 



ONTHOPHAGUS BOVILLI Blackb. 



Plate viii, fig. 50. 



The type of 0. hovilli has the apical segment of abdomen not at all narrowed 

 in the middle, so it is a female, as suspected by Blackburn ; it is much less metallic 

 than is usual in 0. conspicuns, but both sexes of that species vary considerably in 

 colours and structure, and I can only regard the type in question as a rather 

 dingy female of it. 



ONTHOPHAGUS VICTORIENSIS Blackb. 



0. jungi Blackb. 



Plate viii, figs. 51, 52. 



The type of 0. victoriensis is represented in the South Australian Museum by 

 a fragment (its head and prothorax are missing). It belongs to the species 

 subsequently named 0. jungi, and of which Mr. J. C. Goudie mounted sexes on 

 one card from Birchip, Victoria.
