102 CARABlD^l. PTEROSTICHUS. 



depressed, punctured on each side, and with a large punctured 

 fovea terminating in an oblong stria about midway between the 

 dorsal furrow and the exterior margin. Elytra broad, short, 

 widest behind the middle, apex considerably narrowed, moderately 

 striated, having from three to five large impressions irregularly 

 disposed on or near the third interstice ; beneath black, femora 

 pitchy, tibiae and tarsi reddish. Length 5|-6 lines. 



At first sight this species appears to resemble Orinomus, but 

 its characters are wholly dissimilar. The thorax is much longer 

 and therefore more quadrate, the base more truncate, the pos- 

 terior angles less elevated and more acute, the base more 

 depressed and the basal impression extends more considerably 

 upwards ; the form and sculpture of the elytra also are equally 

 dissimilar. 



Local. Bagley Wood, Oxon ; Harleston Woods, near North- 

 ampton, under chips of pine bark in abundance; Windsor; 

 Devonshire, &c. Found also in Ireland.

Winged, depressed, pitchy black or pitchy red, shining. 

 Head large, with a slight fovea on each side between the 

 antennae, three joints of the latter smooth, the upper ones 

 fuscous and pubescent. Thorax cordate, much contracted 

 behind, but the posterior angles rectangular, often rusty red, 

 the dorsal furrow strongly impressed, the base with two oblong 

 smooth striae. Elytra oblong, the shoulders rounded, the sides 

 almost parallel, but a little waved before the middle, rounded 

 and not narrowed at the apex, disk rather depressed, finely 

 punctate-striated, the third stria with three deep impressions, 

 one before the middle, another a little behind the middle and 

 the third at the extremity ; underside and legs rusty red.

 received one (picimanus) ought to stand, because the former had
