This species is about an inch in length. It is of 

 an oblong-ovate form, and wider in proportion to 

 its length than most other species of the genus. 

 The colour is dark brassy, varying considerably in 

 shade in different individuals. The head and thorax 

 are very faintly punctured, and the latter has the " 

 hinder angles very little produced. Each elytron 

 has three elevated lines, and a triple series of rather

 copper colour, united by an oblong tubercle rather 

 indistinctly formed. The outer edge of the ely- 

 tra is slightly sinuated at the apex in both sexes. 

 The under side of the body and the legs are black. 

 This was esteemed till lately one of the rarest kinds 

 of the British Carabi. Although very scarce in 

 England, it is now however ascertained to be pretty 

 copiously distributed over the Western and Northern 

 Highlands of Scotland. Throughout the southern 

 division of the country, the most common species 

 of the genus are C. catenulatus, C. hortenais, and 

 C. violaceus ; but as we advance northwards the 

 two latter gradually become scarce, and their place 

 is supplied by C, glabratus and C. clathratus. Of
