from Sydney, but they vary considerably in the colour of the 

 rostrum and legs. On the males the legs and rostrum (except 

 for their clothing) are entirely black, and the antennae are 

 black except that the funicle is obscurely reddish; on some 

 females the legs, antennae (except club), and apical half or 

 more of the rostrum are flavous (although not so bright as on 

 the Sydney specimens) but on others these parts are very 

 obscure, although (except for the hind femora) scarcely 

 black. 



Belus semipunctatus, Fab., var. poverus, n. var. 

 Numerous specimens (twenty-four) from Goolwa and 

 Mudd Island, are structurally so close to semipunctatus that 

 I cannot regard them as representing more than a variety, 

 they differ from the typical form in being considerably paler 

 (castaneou6-brown, some parts infuscated) and not at all 

 metallic; elytra clothed only along suture (on a few specimens, 

 however, the medio-discal row of spots on each elytron is 

 vaguely indicated), but in particular by the discal carinae; on 

 the typical form the carina on each elytron commences as an 

 oblique, impunctate, slightly elevated line, almost level with 

 the front edge of the metasternum, but on this variety it 

 commences just beyond the metasternum, the space before it 

 being covered with normal punctures ; the post-scutellar 

 depression is also smaller and shallower. 



Belus anguineus, Pasc. 

 B. ventralis, Blackb. 



The type of ventralis is a female of the species identified 

 by both the late Rev. T. Blackburn and myself as anguineus. 

 The species occurs in Western Australia and Queensland, as 

 well as in South Australia (Quorn, Leigh Creek, and Oodna- 

 datta) . 



Belus bison, Blackb. 



This species was tabulated by both Blackburn and myself 

 as having the front femora edentate ; this is usually tfie case, 

 but on a few specimens now before me the front femora are 

 feebly but distinctly dentate; it was also noted by myself as 

 having the "suture not suddenly and strongly raised at base," 

 but the specimens upon which I so noted the species (a very 

 similar one was taken at Ooldea), although belonging to 

 b-ison, are not typical of that species, which usually has the 

 suture strongly raised there. Ooldea, Orroroo, Parachilna. 



Belus tibialis, Blackb. 

 This remarkable species appears to be fairly common at 

 Lucindale ; on the majority of specimens the elytra are almost
