C. picipes, Macl. There are two specimens under the 

 label, but evidently the same species. The elytra are green, 

 with larger seriate punctures than in ('. rufipes, the tarsi are 

 piceous above, clothed below with pale-red or yellow hair. 

 I have specimens taken near Brisbane by myself, others from 

 l^arromine (N.S.W.) taken by Mr. Sloane, that correspond 

 exactly with Macleay's type, and also with the description 

 of C. jucundus, Blkb. I cannot agree with Mr. Skuse's 

 opinion given in the note by Blackburn (Proc. Linn. Soc, 

 New South Wales, 1893, p. 87) as to the identity of C. 

 picipes, Macl., and C. rufipes, Macl. The prothorax varies 

 in colour from blue-black to green. Of a specimen of 

 picipes, Macl., sent to Mr. Blair he writes: "Type (of 

 jucundus, Blkb.) is larger and stouter, but agrees with this 

 specimen in puncturation and in more nitid surface than in 

 'nigritarsis.' " 



C. imperialis, Blkb. The tarsi are nigro-setose, with a 

 few reddish hairs interspersed. Mr. Blackburn placed it 

 amongst those with flavo-setose tarsi in his tabulation. My 

 specimens are from Marmor, Queensland, given me by Mr. 

 H. Brown. 



C. variabilis. Bless., and C. sulcipennis, Hope, were 

 omitted by Gebien in the new catalogue of Junk (Berlin). 

 The former is a very common species in New South Wales, 

 Victoria, and Tasmania. The latter is identical with C. 

 suturalis, Pasc. (vide infra). 



C. setosus, Blkb., is not very appropriately named, since 

 the setae are extremely fine, especially on the upper-surface. 

 In the CO- type lent me by Mr. Blackburn, the setae could be 

 seen only on the epipleurae, in other specimens they are 

 visible (with a lens) on the elytra. It is a large, very robust 

 species, brightlj'- metallic-green, with large punctures of a 

 much darker colour — generally blue — but I have one speci- 

 men in which these punctures are purple. C. nohilis, Blkb., 

 of which I have seen a co-type in the Melbourne Museum, is 

 much more evidently setose, though the fact is not mentioned 

 in the description. There is also a mistake as to locality in 

 the case of setosus. This is given as Victoria in the descrip- 

 tion. All the specimens I have seen (and they are many) 

 have come from Cairns or other parts of North Queensland ; 

 Mr. Blackburn's co-type was labelled Thursday Island. C. 

 nohilis, Blkb., has much larger punctures in the elytral series, 

 and much finer (scarcely evident) punctures on the pronotum ; 

 otherwise the two species are very similar, 



C. perlongus, Blkb. In description the elytra are said 

 "to be "sat seriatim punctulatis, interstitiis planis." A
