438 REVISION OF THE AUSTRALIAN AMARYGMIDES, 



interstices widely and gently convex. I suspect that G. pur^jureus 

 is the insect from Port Lincoln that Mr. Pascoe refers to (Ann. 

 Nat. Hist. 1870, p. 105) as a variety of G. suturalis, sibi, as T 

 have frequently taken, at Port Lincoln, G. purpureus (coloured, 

 as Mr. Pascoe describes the so-called var. of suturalis), but never 

 anything more like C. suturalis. This (C. suturalis) is another 

 species belonging to the same group, and was described by Mr. 

 Pascoe on an example from Western Australia. Through the 

 courtesy of G. Masters, Esq., of Sydney, I have been able to 

 examine a specimen which he tells me was named suturalis by 

 Mr. Pascoe, and which agrees well with the description. It is 

 very close to G. piirpuretis in respect of all characters except the 

 sculpture of the elytra (I attach no importance to the colour of 

 the suture alluded to by Mr. Pascoe, as I find it to vary in 

 C. picrpureus), but .its elytra are very deeply striate, with the 

 interstices strongly elevated, evidently narrower than the inter- 

 stices of G. purpureits and scarcely visibly punctured. It appears 

 to me quite possible that C. anthracinus, described by Mr. Hope 

 (Proc. Ent. Soc 1842, p. 79) in a few words, quite insufiicient 

 for confident identification, may be a black var. of C. 2>urpureus 

 (I have seen a single black specimen of that insect), but I have 

 no means of settling the point, and the application of the name 

 anthracinus to an insect brilliantly shining with golden purple 

 and green colours, because it was first named on a very rare 

 black variety, seems so unnatural as almost to justify a change of 

 name even if my suspicion should prove to be well founded.
