Carabus eleiHttus aptere ; bords du corcelet arrondis, rclcvcs ; corps noir ; 

 elytrcs violettes. Oliv. Enl., iXo. 35, p. -16, /. 7, /. 8'3. 



Head black very sligjlitly tinted with violet, impunctured; 

 anfenncv brownish towards the tips. 



Thorax black, slightly tinted with violaceous, dilated 

 and reflected each side, gradually more reflected to the 

 hind angles, hardly contracted behind, surface concave, 

 with small, numerous, inegular punctures, base nearly as 

 broad as the base of the elytra, basal edge falcate each 

 side, basal angles prominent, acute. 



Elytra cupreous-red, brilliant, strite numerous, obtuse, inter- 

 stitial lines narrower than the strijie, obtuse, humeral edge 

 dilated, reflected, elevated, and rounded ; epijileura con- 

 fluently punctured. 



Pectus with a few punctures at base, lateral margin with mi- 

 nute punctures ; postpectus and venter each side at base 

 with large punctures. 

 The original brilliant pigment of the elytra, which is of a 



reddish-cupreous colour, is very readily rubbed ofl'even by 



a touch of the finger, leaving a i)lackish ground. The ele- 



vatus of authors is said to be an inhabitant of South America, 



probably through error.
