with paler prothorax (but not its disc), elytra and legs (but 

 not tarsi) ; the antennae are also somewhat stouter, but this 

 may be sexual. 



Belts pudicus, Lea. 

 A specimen from Brisbane differs from the type in having 

 the pubescence of the upper surface and on the sides of the 

 lower surface somewhat ochreous; the elytra paler, but with 

 the suture black. The nude space on the middle of the third 

 and fourth abdominal segments is probably due to abrasion. 



Belus hemistictus, Germ. 

 This species appears to be intermediate between those 

 having a distinct carina bounding each side of a subsutural 

 depression and those without such. On one specimen the 

 carina on each side of the depression is quite distinct to the 

 naked eye, appearing as a shining line from the basal third 

 to the apical fifth ; on two others it is faintly traceable to 

 the naked eye but practically disappears under a lens. On 

 a fourth it is more noticeable on the right; than on the left 

 elytron. In the original description the elytra are said to be 

 obsoletely carinate. 



Belus phcentcopterus, Germ. 



This species varies in length from 12 to 18 mm., and 

 some specimens are much paler than others. The femoral 

 teeth are occasionally so small as to be seen only with diffi- 

 culty. 



Belus suturalis, Boi. 



A specimen from Western Australia is much smaller 

 (9 J mm.) than usual, and has the pubescence of a snowy 

 whiteness, instead of more or less stramineous. 



The species of Belus known to me may be tabulated as 

 follows : — 



A. Basal half of elytra strongly contrasted 



in colour with apical half ... ... ... di visits, Pasc. 



AA. Basal half not strongly contrasted. 

 B. Front tibia with a strono; snbbasal 



tooth ... ... ... .... ... linearis, Pasc. 



BB. Front tibia at most denticulate. 

 C. Elytra carinate. 

 a. Femora edentate. 



h. Each elytron with two conspicu- 

 ous spots of unequal size ... hidentatus, Don. 

 hh. Elytral spots not isolated and 

 conspicuous. 

 c. First joint of antennae longer 

 than second and third com- 

 bined ... ... ... ... raripijis. Lea. 



cc. First joint shorter than .second 



and third combined ... ... cristatus. Lea
