CARABID.E. BRADYCELLUS. 165 



hinder angles obtuse. Elytra oblong-ovate, not so broad in front 

 nor so dilated behind the middle as in fulvus, but more convex, 

 distinctly striated, the striae wholly impunctate ; underside of the 

 head and thorax rusty red, breast and abdomen pitchy black ; 

 legs pale testaceous. Length If line. 



The insect described by Sturm under the name collaris is 

 thought by Erichson to belong to the foregoing species; at any 

 rate the descriptions given by Sturm do not correspond with the 

 insect before us. It is a mountain species and is found upon 

 the high moors in North Wales, Yorkshire, Lancashire and 

 Scotland ; less frequent in more southern districts. 



5. B. sixnilis : oblong o-ovatus, piceus ; thorace subquadrato, 

 postice utrinque foveolato, foveis punctatis ; elytris striatis, 

 striis externis obsolete punctatis ; antennarum basi pedibus- 

 que testaceis.

Smaller than collaris, pitchy black, with the thorax sometimes 

 and the suture always pitchy red, palpi and base of the antennae 

 pale. Thorax subquadrate, much shorter and wider than in 

 collaris, a little rounded in front below the angles, very slightly 

 narrowed behind so that the base appears broad, the posterior 

 angles less obtuse, base with a deep punctured fovea on each 

 side. Elytra oblong-ovate, broadest behind the middle, striated, 

 some of the external striae very obsoletely punctured ; underside 

 black; legs pitchy or rusty red. Length li line. 



As the name ruficoUis had been previously employed, I have 

 adopted that which Dejean gave to the species. The insect is 

 extremely abundant on sandy and moory commons where heather 

 grows all over the kingdom.
