knowledge of the fauna of the localities in which the types were 

 collected. Even with this assistance I have not been able to 

 identify all the species of the former two of those authors. 



Beginning with Germar, — fervens is unmistakable, as it is 

 mainly characterised by its undersurface being brilliantly iri- 

 descent (a very rare character in Chalcopterus), and a species 

 presenting this character occurs somewhat commonly all over 

 S. Australia, and agrees very well with the description of fervens 

 in all respects. Germar describes purpiireiis as having its elytra 

 " tenuiter striato-jiunctatis" its puncturation less fine than that of 

 fervens, and its upper surface (except the head) entirely varie- 

 gated with metallic colours ; these are fairly definite characters, 

 and as there is a species (and only one) known to me (it is 

 common all over S. Australia) found in the habitat of Germar's 

 insects presenting these characters I feel no doubt about this 

 identification. Germar describes fastuosus as distinguished by 

 the unusual characters of the seriate puncturation of the elytra 

 being somewhat obsolete and the puncturation of the prothorax 

 stronger than in its allies and crowded near the lateral margins, 

 characters that are combined in one, and one only, of the species 

 before me that occur (and it, too, occurs commonly) in the 

 locality where Germar's species were collected. The above three 

 species also agree in size, &c., with the other characters as stated by 

 Germar under the names mentioned. The other of Germar's 

 names (ncgosics) its author assigns to a species which he describes 

 as having the prothorax black, the elytra " rugosely striate," and 

 the interstices transversely rugulose ; I have seen no Amarygmid 

 to which this description would apply, unless it be a remarkable 

 form in my collection that I am disposed to regard as a monstro- 

 sity and to refer to C. polychroimcs, Pasc, with which it seems 

 absolutely identical in every respect, except that tlie elytra are 

 sculptured in a fashion quite unlike that of any other Amarygmid 

 that I have seen. I have met with another example with this 

 same peculiarity present in a much feebler degree. Unless it be 

 the case that the descriptions of Amanjgmus rugosus, Germ., (and 

 A. sidcipennis, Hope, which Germar thought likely to be the
