pygidium and under-surface are described as being covered 

 with long greyish-yellow hairs. 



DlAPHONIA SUTURATA, Nonfr. 



In many respects the description of this species reads as 

 if it was founded upon a fairly common form of Ablacopus 

 trapezifer ; but as the prothorax is described as "dense et 

 fortiter punctato," presumably it is not that species. It is 

 to be noted, however, that the punctures of trapezifer vary 

 considerably in size and density, although the expression 

 quoted could not (in the dozens of specimens that I have 

 examined) be correctly applied to them. 



Diaphonia caroli, new name. 

 frenchi, Lea; n. pr. 

 The name frenchi having been previously used in the 

 genus by Schoch, I have to propose caroli as a substitute for 

 the species that I also named frenchi. 



A male from Cooktown, in Mr. French's collection, has 

 the pygidium red, except for a medio-basal black triangle, 

 and an infuscate spot towards each side. It has also a small 

 reddish spot on the side of each shoulder. 



DlAPHONIA PALMATA, Schaum. 



PI. xii., figs. 100, 110. 



This species was originally referred to Schizorrhina, and 

 why it should have been transferred to Lyraphora is a mys- 

 tery. Its clypeus and mesosternal process are much as in 

 Diaphonia dorsalis, and it is certainly congeneric with that 

 species. The large basal marking on the elytra is somewhat 

 variable in its outlines, and the disconnected spots on each 

 elytron vary in number from one to three. 



It has been recorded as occurring in Adelaide, but pro- 

 bably in error ; specimens that I have seen are from New 

 South Wales and Queensland. 



DlAPHONIA MELANOPYGA, n. Sp. 



d • Black ; prothorax (extreme base and apex and a 

 small spot on each side excepted), scutellum (sides excepted), 

 and elytra (suture excepted) of a rather light-castaneous. 

 Under-surface moderately clothed with ferruginous hairs, be- 

 coming darker on legs. 



Head with dense and rather coarse punctures. Clypeus 

 moderately notched in front, tips and sides rounded ; punctures 

 coarser than on head. Club as long as clypeus is wide. Pro- 

 thorax rather convex, sides feebly decreasing in width from
