Chalcopterus, Notes on Described Species of. 



C . puncticoUis, Hope. Specimens from South Perth 

 were compared with type by Commander J. J. Walker, R.N., 

 M.A., who writes that they are identical. Below is given a^ 

 description taken from a specimen compared with the type. 



C. opacicollis, Macl. In the Australian Museum are th& 

 Gayndah types, though, as was the unfortunate custom with 

 Sir W. Macleay, they are not specially marked as types. 

 Under the label C. opacicollis, Macl., are two specimens which 

 are tiuo different species. Denoting these by A and B respec- 

 tively, A has the prothorax purple and blue (the former pre- 

 dominant), the elytra variegated, suture golden, then purple, 

 green, and again golden-metallic at the sides, the seriate 

 punctures are larger than in B, with the intervals distinctly 

 punctate, and tarsal vestiture black. In B the prothorax is 

 metallic-black, the elytra blue, with purple at the suture 

 and golden-green at the sides, the seriate punctures smaller 

 than in A and subelongate, the intervals scarcely perceptibly 

 punctate, while the tarsal vestiture is red. A is the species 

 considered by Blackburn as C. opacicollis. It is one of the 

 commonest species in South Queensland and Northern New 

 South Wales, and is probably C. vinosus, Pasc, and C. 

 resplendens, Boisd. B is the species described by Blackburn 

 as G. hunterensis. From Macleay's description the words 

 "Thorax brassy-black, opaque, and minutely punctate," 

 "Eytra ... of a purplish colour, becoming green to- 

 wards the sides eight rows of small, closely- 

 placed, subelongate punctures" clearly point to B as the 

 type described, since the seriate punctures in A are not at 

 all elongate, and the thorax is not at all black. 



C. grandis, Macl. In Blackburn's table, this is placed 

 under the group with ''tarsal vestiture black." The type 

 specimen has the tarsal vestiture yellow. 



C. obsoletus, Macl. = (7. fastuosus, Germ. There are some 

 slight colour distinctions, and the Queensland specimen is 

 rather larger than specimens (identified as C. fastuosus by 

 Blackburn) from South Australia. Confluens, Blkb., is the 

 same species, the distinction drawn by its author is, I think, 

 only individual variety. 



G. rufipes, Macl. The type specimen has the pronotum 

 distinctly dark-blue (described as having ''thorax black"). 

 It is of a much darker shade than that of the elytra. The 

 tarsi are black above, clothed with reddish hair. Specimens 

 from Cunnamulla, given me by Mr. Lea, are identical. A 

 specimen compared with type of nigi^itarsis, Pasc, proves its 

 synonymy with that species.
