 8-10 quam prsecedentes baud brevioribus; prothorace quam

Diflfers from nearly all its congeners in having the whole under- 

 surface (especially the ventral segments) brilliantly iridescent. 

 In build closely resembling C. loitics but differing inter alia in its 

 jirothorax a little less transverse (not more than once and three- 

 quarters as wide as long), the seriate punctures of its elytra 

 considerably finer and closer (four or five in the middle part of 

 the intermediate rows on a length equal to the width of an 

 interstice), the interstices even less visibly punctulate, and the 

 upper surface less nitid. Compared with fervens, Germ., (which 

 also has the undersurface iridescent) this insect is a much less 

 robust and more elongate species, with longer legs, hind tarsi 

 much longer, puncturation finer throughout, &c.
