Leptops polyacanthus Pasc. 



There are two spécimens before me which I refer to this species. 

 They difTer from Baileyi, to which they are very close, in having 

 no large tubercles at apex of prothorax, and the interocular 

 tubercles (1) separated a greater distance, and almost overhanging 

 the eyes. The elytral tubercles, however, are much the same in size 

 and position. A third spécimen before me is probably a variety, it 

 differs in having the inter-ocular tubercles almost obsolète, and those 

 on the elytra rounded instead of conical. 



Hah. : Queensland : Dawson River (2). 



? Var. reductus Pasc. 



There is a spécimen in the Brussels Muséum, marked as having 

 been seen by Pascoe, and noted as « Leptops reductus Pasc. Queens- 

 land ». If, as seems probable, it is correctly named, I can only 

 regard it as a variety oi polyacanthus. This spécimen does not agrée 

 with the description in ail particulars, however, as it bas four 

 tubercles on the third interstice and five on the fifth, instead of 

 three on each; but thèse tubercles are certainly variable as on 

 another spécimen belonging to that muséum there are five on 

 each, whilst on a spécimen of my own there are four on each. 



Leptops Duboulayi Pasc. 



In this species the intermediate carinae of the rostrum end 

 abruptly; the pectoral armature is more pronounced than in 

 tribulus, but much less than in colossus. Some spécimens from 

 Champion Bay (the original locality) are clothed with pale brow- 

 nish scales, but others from Central Australia are clothed with 

 greyish scales, largely varied with white, the white scales on one 

 spécimen forming two distinct lines from apex of prothorax to apex 

 of elytra. Pascoe makes no mention of a carina on the prothorax; 

 on four females before me one is présent, but on the only maie 

 there is none.

 Warburton Range. 



Leptops colossus Pasc. 



M. Pascoe had doubts as to the correct mating of the sexes of 

 this species, but Duboulay (from whom he received the types) had 



(1) Ou oiie specimeu thèse tubercles are much less distinct thau on the other. 



(2) A spécimen in the Australiau Muséum is labelled « Interior S. A. ».
