50 MANDIBULATA. — COLEOPTERA. 



longitudinal line : the surface is thickly granulated^ and rugose behind and 

 at the hinder angles ; the margin is rounded^ a little elevated^ the posterior 

 angle a trifle produced and obtuse : the thorax is truncate in front^ and deeply 

 notched behind : the elytra are oblong-ovate,, of a rich green^ brassy^ or violet 

 tinge^ with three interrupted elevated striae, having three lines of equal size 

 between each ; the suture and elevated margin are usually deep black ; the 

 under parts of the body and the legs are deep black; the basal joints of the 

 antennae are bronzed black, the terminal joints brownish and pubescent. 



Var. ^. More elongated ; the posterior angle of the thorax shorter ; the elytra 

 vrith the central line of each series much elevated, the external ones being 

 rather obsolete. 



Var. y. With the elytra green, striated anteriorly, with the apex and margin 

 very rugose. 



One of tlie most variable and elegantly sculptured species of 

 Carabi ; not uncommon in the neighbourhood of London and other 

 places, and particularly abundant near Dover. From the very 

 dissimilar aspect of var. I3, I think it highly probable that it will 

 prove to be a distinct species. It appears to be the Ca. consitus of 

 Panzer, fas. cviii. f. 3.

Above dull brassy; sometimes greenish or deep black: head projecting, thickly 

 punctate, with an impression between the antennse : thorax transversely qua- 

 drate, rather narrower behind, and slightly notched posteriorly; its surface is 

 thickly punctate, with an impressed longitudinal line, and a deep and rather 

 large impression or fovea near the hinder angle on each side : elytra oblong- 

 ovate, dilated beyond the middle ; rather convex above, with three catenulated 

 lines on each, composed of oblong, elevated, smooth tubercles, and between 

 each a single, elevated, smooth, uninterrupted line ; the entire surface is thickly 

 punctate : the body is smooth, glossy black beneath : the legs and four basal 

 joints of the antennae are black ; the rest brownish and pubescent. It has 

 generally the rudiments of wings. 



This species varies much in colour, but the black varieties are 

 rare near London; whereas the aeneous ones are not unfrequent, 

 and are found in profusion in rotten willows, especially in the early 

 spring months ; at other times they are usually taken beneath 

 mosses, dead leaves, stones, &c. Dr. Leach has observed that the 

 specimens taken in mountainous districts were mostly very dark- 

 coloured, and vice versa.
