uneven. Elytra convex, elongate-oval, a third wider than prothorax, nearly two 

 thirds longer than wide, shoulders rather square, no sinuation behind; striae 

 fairly deep and very clean cut, impunctate, shallower at sides and behind, but 

 I and 2 are deep to apex, 8 deep throughout, scutellary striole obsolete; 

 intervals a little convex, i somewhat raised and narrower towards apex, 3 with 

 a pore behind middle and another before apex, surface a little uneven. No 

 appreciable microsculpture. Underside impunctate; tarsal joint 5 glabrous 

 beneath. 



A little smaller than average examples of T. pallipes Germain, the eyes 

 flatter, the prothorax wider, its sides straight behind, its base punctate, the 

 elytra much more deeply striate and without microsculpture.

Pterostichus walkeri sp. n. — Fig. 3. 

 Length: 13 — 13,5 mm. Width: 5 — 5.3 mm. 

 Black: the elytra shiny in the J*, a little 

 dull and sericeous in the $. 



Body apterous. Head convex^ neck 

 somewhat dilated, clypeal suture fine, with a 

 small pore or impression at each end, re- 

 presenting the frontal foveae, front and vertex 

 with a few vague rugae, labrum and clypeus 

 both slightly emarginate, eyes small and rather 

 flat, antennae barely reaching base of pro- 

 thorax, ligula bisetose, truncate at apex, the 

 paraglossae narrow, membranous, separated 

 from the ligula on each side by an evident 

 notch, curving inwards and extending rather 

 beyond it, tooth of mentum bifid, a pair of 

 setiferous pores just below it, the epilobes 

 wide, rounded at apex and extending a little 

 beyond apex of lobes. Prothorax convex, 

 quadrate, rather more than a half wider than 

 head, a third wider than long, widest just before middle, base a very little 

 wider than apex, both slightly and widely emarginate, front angles rather 

 sharply rounded, sides bisetose, with a very narrow border, gently rounded 

 but straight just before base, hind angles slightly obtuse, though fairly 

 sharp, the pore within the angle; median line short and fine, joining the two 

 shallow to moderately deep transverse impressions, inner basal foveae short and 

 lightly impressed, outer foveae wanting or obsolete, surface a little uneven and 

 with a few vague striae, a few very faint punctures scattered along the basal 

 area. Elytra flat, a fourth wider than prothorax, a half longer than wide, 

 widest a little before middle, basal border entire, sides gently rounded up to 

 a fifth from base, where a further widening and flattening takes place, a deep 

 emargination on each side before apex, the inner plica invisible from above, 

 the extremities, which are separately rounded, forming a declivous apical lobe; 

 striae fairly deep, almost imperceptibly crenulate (more evidently in one of the
