//«6.— Barron Falls, KQ (Mr. A. Koebele). 



This species strikingly resembles the preceding, but the antennae 

 are so dissimilar as to preclude the supposition that it is a variety 

 of that species. 



Calochromus Guerinii, Macl. — This species is somewhat 

 variable in regard to colour and size. I have taken specimens 

 on the Tweed River which were carefully compared, and 

 agree, with the type specimens, and to which the description of 

 M. Leon Fairmaire's C. discicollis exactly apply; the latter name 

 must therefore fall. 



C. insidiator, Fairm Ilah. — Forest Reefs, IST.S.W.

 Beverley, W.A.
