Elytra convex, a fourth wider than prothorax, a half longer than wide, basal 
border entire, sides nearly parallel, though faintly emarginate at a third from 
base and more evidently near apex; striae fairly deep, impunctate, 9 leaving 
the marginal channel a little behind shoulder, a short scutellary striole between 
1 and 2; intervals moderately convex, inner ones equal, outer ones gradually 
narrowing towards apex, a tenth interval present, which gradually widens 
behind up to a fifth from apex, where it is as wide as the inner intervals, and 
then contracts rapidly to the apical sinuation, 3 with three pores; surface 
smooth and impunctate. Microsculpture isodiametric and conspicuous on the 
elytra; on the head and prothorax the meshes are much finer, isodiametric on 
the head, slightly wider than long on the prothorax. Underside impunctate, 
prosternal process finely bordered at extremity, metepisterna a half longer than 
wide, last ventral segment with one seta on each side in the ¢, 2 in the Q. 
Femora somewhat dilated; mesotibiae J a little curved; metatibiae J suddenly 
dilated a little after middle to twice the width of the basal part, the dilated 
part flattened; first metatarsal joint with a slight outer sulcus, joint 5 setulose 
beneath. 
I know of no species with which I can usefully compare this, but I may 
draw attention to one or two unusual features, viz. the very shallow basal 
foveae of the prothorax, the practical absence of outer foveae, and the very 
curious form of the ¢ metatibiae.

Pterostichus skottsbergi sp. n. — Fig. 5. 
Length: 10 mm. Width: 3.4 mm. 
Black: palpi, joints 1 to 3 of antennae, and tarsi more or less dark ferru- 
ginous, tibiae piceous. 
Body apterous. //ead convex, clypeal suture fine, a slight depression at 
each end, and a third transverse depression just behind middle, surface very 
smooth, eyes rather flat, antennae just reaching base of elytra, tooth of mentum 
bifid. Prothorax moderately convex, subcordate, about a fourth wider than head 
and as much wider than long, widest a little before middle, base slightly wider 
than apex, sides narrowly bordered, gently rounded 
in front and slightly sinuate before base, a pore 
and seta at two fifths from apex, none visible at 
hind angles, which are a little acute and moderately 
sharp; median line fine, deeper close to base, front 
transverse impression evident but shallow, basal 
foveae short but moderately deep, outer ones ob- 
solete, surface nearly smooth. 4l/yira_ convex, 
subovate, a fourth wider than prothorax, three 
fourths longer than wide, a moderate emargination 
on each side near apex; striae deep, impunctate, 
a short striole present, intervals convex, 5 to 7 
becoming very narrow behind, 3 with three pores,
