Pitchy black, sometimes reddish pitchy. Head convex, smooth, 

 with an oblong fovea on each side in front between the antenme 

 and a transverse punctured impression behind the eyes, antennae 

 pitchy red. Thorax elongate, heart-shaped, narrowed behind, 

 posterior angles acute and elevated, rather convex, very shining, 

 with a deep longitudinal dorsal furrow, met in front by a row of 

 deep punctures, base with two deeply impressed punctured fovese. 

 Elytra oblong-ovate, humeral angles much rounded and rather 

 narrow, sides widest behind, disk very shining, punctate-striated, 

 the striae rather obsolete at the sides and apex, between the second 

 and third from the suture three deeper impressions ; legs rusty 

 red with the thighs darker. Length 3~ 4 lines. 



PaykulPs and Panzer's name excavatus must be adopted for 

 this species ; C. rufipes of Fabricius is identical with Calathus 

 fuscus. 



This species is found in profusion on the Welsh mountains, 

 in the north of England, and in Scotland and Ireland. I have 

 taken it abundantly also in damp woods in Kent and on the 

 shores of the Thames below Gravesend. 



2. P. septentrionis : alatus, nigro-piceus ; thorace subcordato, 



postice utrinque foveolato ; elytris oblong o-ovatis, subtiiiter 

 punctato-striatis, punctis tribus impressis ; pedibus piceis.

 Harpalus rufipes, var. c., Gyll. Ins. Suec. 2. 97. 



This species is larger and longer than excavatus and is further 

 distinguished by its ample wings. It is pitchy black with the 

 mouth and palpi red, the antennae pitchy rufous. Thorax shorter, 

 less cordate, wider at the base, with the latter not punctured but 

 furnished with two large foveae, the anterior margin also is more 

 sparingly punctured, disk depressed and much wrinkled trans- 

 versely on each side the dorsal furrow. Elytra more elongate,
