420 REVISION OF THE AUSTRALIAN AMARYGMIDES, 



as those concerning the earlier descriptions. Here Mr. Masters 

 has come to my help with great kindness and has lent me speci- 

 mens which he knows to be identical with many of those on 

 which descriptions were founded. 



In this first instalment of the present memoir I offer to the 

 Society descriptions of a number of new species of Chalcopterus. 

 In the second and concluding instalment I hope to supply a 

 tabular statement of the distinctive characters of these new 

 species and of most of the species previously described, together 

 with a revision of the much less numerous species of Amarygmtis.
