424 REVISION OF THE AUSTRALIAN AMARYGMIDES, 



but I can find no other difference. From various localities in 

 A^ictoria and S. Australia I have seen examples with dark green 

 elytra which are somewhat less nitid (I take this to be affinis, 

 Blessig). From Western Australia I have a specimen with the 

 elytra bright green and very nitid ; as this form is a trifle more 

 elongate and less convex (the summit of the outline curve of the 

 elytra viewed from the side being scarcely in front of the middle) 

 it is possible that it represents a distinct species. Examples from 

 the Victorian Alps are of the typical form. Queensland specimens 

 have elytra inclining to reddish-copper colour, but do not seem to 

 differ otherwise. Amarygmns Howitti, Pasc, seems to be the 

 typical form. Specimens from the Fraser Range (taken by the 

 Elder Exploring Expedition) differ from the type only in having 

 their elytra of a ])urplish tone.
