far the greater number of specimens are of a metallic-green colour, only two being 

 violaceous blue and having the first four joints of the antennae rufous, but differing in 

 no other way whatever.

Again closely allied to C. germari and similarly coloured species, but, according to 

 von Harold, to be separated by the very fine punctuation on the disk of the elytra, and 

 the colour of their apex, which is rufous and extends much further upwards than in 

 the other allied species.

The most important character of separation between this species and others similarly 

 coloured is the sharply raised humeral callus and another equally sharp ridge extending 

 from the shoulder nearly to the apex. "Whether this character is peculiar to the 

 female only or to both sexes, the author does not mention. I have now a single 

 specimen from the collection of Sturm, and contained in that of M. Salle, which 

 has the above characters well expressed ; it is a female, with bright metallic-green 

 elytra.

I have now no doubt that C. uniformis described by me is but a variety of the 

 present species, as I suspected at the time I described it. The upper colour of the 

 insect is a greenish bronze, the variety being entirely dark rufous, which latter colour 

 occupies the extreme sides and apex of the elytra only of normally coloured specimens ; 

 in this respect it resembles several species, but differs from all in the rufous first six 

 joints of the antenna?, a character which is constant in all the specimens.
