but somewhat irregular across middle. Elytra not much 

 wider than prothorax, moderately narrowed to basal third, 

 and then parallel-sided to near apex, suture strongly spinose; 

 about basal third with dense and rather coarse punctures, 

 becoming much smaller from about the middle; each with two 

 or three feebly-elevated lines. Length ( S , 9)> 12-22 mm. 



9 . Differs in having shorter antennae and legs, longer 

 and more parallel-sided elytra, wider abdomen, and hind 

 femora with much shorter clothing along under-surface. 



Hab. — Northern Queensland (Blackburn's Collection and 

 National Museum, from C. French), Endeavour River (C. 

 French), Cairns (E. Allen). Type, I. 5704. 



One of the specimens in the National Museum was 

 labelled by Mr. Blackburn as near acutus ; from that species, 

 however, it differs in having the prothorax shorter, wider at 

 the base, and much less parallel-sided, with the tips of elytra 

 very different; each elytron has the suture strongly acute, 

 with the space near it either very feebly notched (fig. 19) 

 or evenly rounded (fig. 21), but on the only female before 

 me the sutural spine is rather small and the notch distinct 

 (fig. 20) ; her antennae (unfortunately broken) are evidently 

 considerably shorter than those of the male, with the serra- 

 tions less pronounced. In some respects it appears to 

 approach Aposites. The clothing on the prothorax, scutel- 

 lum, extreme base, and basal sides of elytra has a rather 

 loose woolly appearance, on the rest of the elytra it is very 

 short and depressed ; on some specimens, to the naked eye, a 

 narrow marginal white stripe may be traced from the base 

 to the apex. 



One of the specimens in the National Museum is labelled 

 as from South Australia, but probably in error. 



Uracanthus triangularis, Hope. 



Typical form. Each elytron with a conspicuous glabrous 

 subtriangular patch behind the shoulder, the patch margined 

 with denser clothing (appearing like a conspicuous irregular 

 white line) than the adjacent parts ; apex also conspicuously 

 glabrous and acutely bispinose. 



Var. A. Apex of elytra not glabrous, but slightly 

 darker than the adjacent parts, subtriangular basal natch 

 with clothing bounding it no denser or paler than elsewhere; 

 tips acutely bispinose. Length, 27-31 mm. This variety 

 is distinguishable from some forms of simulans only by the 

 acutely bispinose apex of each elytron. It occurs in New 

 South Wales and Victoria (Mr. D. Best reared one specimen 

 of it from a species of Lomatia).
