the intervals plane and without any puncture on the third interval ; 

 under side and legs piceous red. Length 17 mm. ; width 5|- mm. 



Eesembles P. caffer, but the prothorax is not so much rounded 

 behind, and the intervals of the elytra are plane, and the third one 

 has no puncture. 



Hah. Natal (D'Urban). 



Ptebostichus natalensis, Bohem. 

 Feronia (Steropus) natalensis, Insect. Caffr., i., p. 186. 



Black, shining ; antennas, palpi, and tarsi ferruginous ; head 

 smooth, frontal impressions nearly obsolete ; prothorax hardly 

 rounded laterally, with the posterior part slightly attenuate and 

 curved, with the outer margin very much recurved, longitudinal 

 median line on the disk very fine, lateral posterior depressions very 

 slight ; elytra oblongo-ovate with the humeral angle sharp convex, 

 striate, intervals a little convex, smooth, the third one impunctate, 

 no scutellary stria. Length 4 mm. ; width 4 J mm.

The description of P. natalensis, applies also to this species, but 

 the frontal impressions are much deeper, the lateral part of the 

 prothorax is a little less attenuate behind, and the outer margin is 

 not recurved, the median longitudinal line is well defined, and there 

 is a sulcate posterior impression on each side between the median 

 line and the outer angle ; the elytra are oblong, convex, striate, with 

 the intervals smooth and nearly plane, the third interval has two 

 punctures, a post-median and a supra-apical one ; there is a scutellary 

 stria on each side. Length 13J mm. ; width 4f mm. 



Hab. Cape Colony (Grahamstown). 



Pterostichus lugubrinus. 



Very closely allied to P. congruens ; colour alike, shape of the pro- 

 thorax similar, but the posterior impressions between the median 

 discoidal line and the outer angle are very faint, and have no longi- 

 tudinal sulcus ; the elytra are nearly oblong, the striae are well 

 marked, the intervals plane, and the third one has two punctures, 

 a sub-basal and a median one, no scutellary stria ; under side piceous 

 red. Length 12^-13 mm. ; width 5 mm. 



The distinctive characters of this species, as differentiated from 

 P. congruens, are the absence of a posterior lateral elongated sulcus, 

 and the position of the two punctures on the third interval which are 

 situated in the anterior instead of the posterior part. 



Hab. Cape Colony (Somerset East).
