acute. Scutellum feebly raised. Elytra more than twice the 

 length of prothorax and much wider (especially in (J) at base, 

 subcordate, apex feebly but distinctly emarginate; striate, the 

 striae almost entirely concealed except towards sides and apex, 

 the sutural one is, however, traceable throughout ; shoulders 

 rounded, raised, a depression at their sides immediately behind 

 sides of prothorax. Under surface and legs densely punctate, 

 the punctures entirely concealed by scales. Anterior tibice with 

 small obtuse teeth on their lower surface. Length 6f , rostrum 24; 

 width 3J mm.

I have described the usual form of the dark mottling of scales, 

 but it is extremely variable: in several specimens under exami- 

 nation the prothoracic scales are entirely white, and on the elytra 

 there are but few dark spots, some eye-like in character. 



Yar. BicRUCiATUS (Faust MS.). 



Scales white: a slight brown patch on forehead: on elytra a 

 sutural patch of brown scales commencing at scutellum. triangu- 

 larly dilated then suddenly narrowed and again dilated, the second 

 patch enclosing a white spot and terminated at middle: sides 

 about middle with two spots, the posterior one of which encloses 

 a white spot, each side of apex with a small brown spot. 



Hab. — Australia (Herr J. Faust) — X.A. : Victoria River 

 (Mitchell's Expedition) — W.A. : Swan River (Lea). 



A well marked but not always constant variety; both dilated 

 spaces on the suture may enclose a white spot, or neither may. 

 In a pair (taken in cop.) from the Swan River the 9 i^ exactly as 

 described, but the g has the markings black, with a patch on 

 the prothorax and additional markings on the elytra: it shows a 

 decided approach to some of the varieties of hictuosus. 



AOXYCHUS STRIATUS, n.sp. 



Black, rostrum highly polished and tinged with red, an tennis 

 piceous-red, eyes dark brown. Densely clothed with white
