portion; granules larger and more conspicuous on the posterior 

 portions of the third and fourth interstices, on the fourth form- 

 ing a moderately strong projection on either side of the elytra; 

 fifth, sixth, and seventh interstices with rows of smaller but 

 evident granules, on the fifth more conspicuous near shoulder. 

 Undersurface depressed at base; with small, scattered punctures, 

 the apical segments more coarsely punctate. Anterior coxk 

 contij,'uous; anterior tibiai moderately strongly curved; posterior 

 tibia; strongly curved at apex, with a strong projecting spine on 

 undersurface, above apex. 



9. More ovate; prothorax feebly dentate at, sides, with a small 

 tooth anterior to subapical constriction; elytra without pro- 

 minent granules on the fourth interstice; anterior tibiae very 

 feebly curved, posterior straight, without spur. Binievsionx : 

 ^. 15x6 mm.

Mr. I-ea has identified C. sejndioides as the female of C 

 calcaratus; Sir W. Macleay, however, gave the habitat of C 

 sepidioides as the Murrumbidgee, which suggests that it is rather 

 a synonym of C. maculatus; personally, I agree with Mr. Lea's 

 identification, as the type is much more strongly dentate than 

 the female of C. maculatus; probably the locality given is wrong. 

 I think the name sepidioides should be dropped, although it is 

 unfortunate that the species was described before C. calcaratus, 

 but on the same page. 



The male of C. calcaratus may be readily recognised by the 

 spur on the posterior tibife. The granules on the fourth inter- 

 stice give the insect somewhat the appearance of a smaller 

 edition of C. }joheniani, though, in that species, the granules are 

 lar<rest on the fifth interstice. 



A male from Tarcoola differs from the usual type, in having 

 the sides of the prothorax dentate anteiior to the' middle, as in 

 the female; the prothorax is also more closely granulate. 



Another male has the protlioracic granules almost obliterated. 

 A third male has the posterior tibise less strongly curved, but 

 with the spur distinct.
