above will examine them and report whether they are likely to 

 be identical with IcevicoIMs. It is an extremely isolated species, 

 and can be at once distinguished from all the other Chalcopieri 

 that I have seen by the following characters in combination — 

 ocular sulci well defined, tarsal vestiture fulvous, legs dark, 

 prothorax subtrapezoidal and impunctate. I may note that I 

 have seen two examples from Narrabri, N.S.W., sent by Mr. 

 Masters for examination, which differ from typical specimens of 

 C. Icevicollis only in being larger (long. 7 lines) and having green 

 elytra ; it is just possible that this form may be that which 

 Boisduval named cohcmbinus, and I think it a mere variety of 

 Icevicollis, Blessig. 



C. PiciPES, Macl. 



Mr. Skuse has had the kindness to examine the type of this 

 insect for me, and reports that the only difference he can find 

 between it and riifipes, Macl., is in the elytra of the former being 

 of a greenish colour. 



The following are the species of Chalcopterus described since 

 the publication of Mr. Masters' Catalogue of Coleoptera and before 

 the date of this Revision.

Amarygmus. 



The name A7}ia7\ijgmus has been limited by M. Blessig to those 

 species which present the characters that I have enumerated in 

 the first part of this memoir as distinctive of Chalcoj^terics, with 

 the exception that their mandibles are bifid at the apex. Not- 

 withstanding M. Blessig's work, however, subsequent authors 

 have ignored the distinction and attributed to Amarygmus the 

 species that M. Blessig would have called Chalcopteri without 

 even referring to the structure of the mandibles. It is there- 

 fore a matter of some difficulty in revising the Amarygmides
