spots and base with dense and rather large punctures, else- 

 where with very small ones. Length, 29-33 mm. 



Hob. — Western Australia (W. du Boulay), Mullewa 

 (Miss J. F. May), Kalgoorlie (C. French). Type, I. 5689. 



A rather large dark species. To the naked eye, each 

 elytron appears to have a large pale spot (slightly longer than 

 rthe prothorax), but this is entirely due to the pubescence 

 there, being more crowded and slightly paler than elsewhere. 

 There are some long straggling hairs at sides of prothorax. 

 The four specimens before me appear to be all males. 



The species of the genus may be tabulated as follows: — 



Most joints of antennae of male multidentate. 



Elytra imicolorous ... ... ... ... westwoodi 



Elytra bicolorous ... ... ... ... ... variegatus 



No joint of antennae multidentate. 



Apex of elytra unarmed ... ... ... ... simplex 



Apex of each elytron bispinose. 



Elytral clothing not uniform ... ... ... bimaculatus 



Elytra! clothing uniform. 



Derm of elytra pale ... ... ... vulidus 



Derm of elytra dark-brown ... ... uniformis 



Aposites. 

 This genus is certainly very close to Neostenus, as stated 

 by Pascoe, but it is quite as close to Uracanthus. Lacordaire 

 (VIII. — 203) widely separated them on account of the middle 

 cotvloid cavities being open at the sides in Aposites and closed 

 in Vracanthus. They appear to me, however, to be open to 

 very much the same degree in both genera. Aposites has the 

 prothorax wider at the base than in most species of Vra- 

 canthus, and somewhat shorter elytra, more narrowed 

 posteriorly; but it is not always easy to place some apparently 

 i connecting species . 



Aposites maoilentus, Pasc. 



Four specimens (from South Australia and Victoria) 

 before me appear to belong to this species; they are all 

 males (the hind femora are densely clothed with yellowish 

 pubescence along their under-surface), and have the suture 

 spinose at apex and each of the four basal segments of 

 abdomen with two glabrous spots on each side. 



Aposites niger, Blackb. 



This species varies considerably in size, but is readily 

 distinguished from the preceding species and from lanaticollis 

 hy each of the four basal segments of abdomen having but 

 one glabrous spot on each side. It occurs at Eucla, Mul- 

 lewa, "Murchison, and Tennant Creek. .
