The (liaf,'nosis of C. Bovilli may be read as applying to this 

 species excej»t in respect of the characteis mentioned above. It 

 is jtosMible that the unique tyf»eof C. HoviUi n>ay be a black var. of 

 a species that is ordinarily brif,'htly coloured. If that be the case, 

 and if I am right in thinking that that type is a male and that I 

 have not seen a male of C. (jracilior (in which case both the 

 antennal differences and tho.se in colour might be non-specific), 

 the two species aie excessively closely allied ; but even so, I think 

 them to be certainly distinct on account of the very marked 

 difference in their sculpture, the puncturation of tlie protljorax in 

 gracilior being very considerably finer and closer than in JiovilH, 

 while the interstices of the elytral strife in the former are very 

 distinctly ])unctured and in the latter all bnt impunctate, the 

 puT\ctnres heing scarcely discernible even with a powerful Codding- 

 ton lens. In my tabulation this insect falls in a small very 

 polymorphous group of species associated by the unusual and 

 cons[)icnouH (but not really important) character of the under- 

 surface being iridescent and of metallic colours.

The Victorian insect, to which I somewhat confidently aj)ply 

 this name, presents the following characters in combination : — 

 ocular sulci at their maximum develo|)rnent (ve.iy wide, deep, and 

 ]Qng, — not foveiforni), tarsal vestiture black or iifarly so, interval 

 between the eyes (including the sulci) just about equal to the 

 length of the basal joint of the anteniue, size at most moderate. 

 These characters are shared with several other forms, which I 

 believe to be good species, but the group of CliaJcopteri, consisting 

 of the species thus distinguished )»resents to me much greater 

 difficulties than any otheis of th*; genus ; fr)r on the one hand it 

 contains some most variable species, and on the other hand it
