Belus bison, Blackb. 

 Three specimens under examination (two from South 

 Australia and one from Tasmania) evidently belong to this 

 species. In one of them the antennae are really black, in 

 another they are slightly diluted with red, and in the third 

 decidedly diluted with red. 



Belus tibialis, Blackb. 

 This species is evidently very close to linearis, ^'^) and 

 agrees with it in the very remarkable tibiae and tarsi. The 

 description of the abdominal clothing, however, does not agree 

 with specimens of linearis before me. 



Belus amplicollis, Jekel. 



Four specimens before me (from Port Denison and More- 

 ton Bay) evidently belong to this species, but all differ in their 

 abdominal clothing, this, however, being almost certainly due 

 to abrasion. On a specimen, apparently in perfect condition, 

 the abdomen is densely clothed with white pubescence at the 

 sides from base to apex, the basal segment in addition has a 

 large white spot on each side of middle, and the three fol- 

 lowing segments each have similar but smaller spots. In two 

 of the other specimens faint traces of these spots can be 

 noticed, but in one of these the clothing at the sides of the 

 basal segment has evidently been worn away through friction 

 with the femora; in the fourth specimen the median spots 

 are entirely absent. With age the violet gloss of the elytra 

 is apt to disappear. 



Belus bidentatus, Don. 



This species varies considerably in the intensity of its 

 colour, some specimens being (except for the head, which is 

 always black) of a rather pale reddish-brown, with still paler 

 femora and tibiae; whilst others have the derm and appen- 

 dages almost entirely dark-browm. Some have numerous 

 minute spots in addition to the two conspicuous ones on each 

 elytron. On each elytron there are usually three carinae, 

 but of these only the one nearest the suture (being the third 

 interstice raised for a portion of its length) is always distinct, 

 the others usually being feeble and sometimes altogether 

 wanting. The male has the rostrum behind the antennae with 

 denser and coarser punctures than in the female. 



Belus longicornts. Lea. 

 Two specimens from Hobart appear to belong to this 

 species, but differ from the type in being smaller (6 mm.), 



(4) Described from Queensland ; my specimens are from King 

 George's Sound.
