310 Capt. T. Broun on new 



men, the epipleurse, and the flanks of the prosternum are 

 smooth. 



Length 2f , breadth 1^ lines. 



Capleston, Westland. Two examples found by Mr. Cavell. 



Group Feroniidse. 



Pterostichus Lewisi, sp. n. 



Elongate, subparallel, only slightly convex, shining ; black, 

 the tarsi and antenna piceous. 



Head rather large, much narrower than the thorax, with a 

 few fine, sometimes obsolete, transverse strias behind, and 

 some oblique or curved ones between the eyes ; frontal im- 

 pressions elongate. Thorax not appreciably broader than 

 long (6 X 6^ milHm.), slightly wider near the front than it is 

 elsewhere, the sides but little rounded, gradually and slightly 

 narrowed behind the middle ; the posterior angles are rectan- 

 gular, but in one example there is a slight thickening of the 

 margins that causes the angles to appear prominent ; across 

 the surface there are some fine stride ; the deep dorsal channel 

 is somewhat expanded towards, but does not reach, the front 

 margin ; there is a rounded impression near each anterior 

 angle ; the basal foss^ are a little flattened externally and 

 generally exhibit a smaller outer fovea in each ; the middle 

 of the base is slightly depressed and wrinkled. Elytra 

 slightly narrowed towards the dentiform shoulders, the apices 

 broadly rounded; each elytron has seven discoidal strias, 

 these are much interrupted ; here and there the elongate 

 impressions are replaced by punctures, 4;he sculpture becomes 

 coarser behind. 



Scutellum striate. Thorax with four or five setae on each 

 side. The last ventral segment in the male has two punctures 

 at each side of the middle, the female has three. 



Like No. 1791 (P. irregularis). The surface less glossy ; 

 the genge more swollen behind the eyes ; the inter-antennal 

 groove shorter, in the transverse direction ; the second joint 

 of the antennge rather longer; the sculpture of the head and 

 thorax very much finer ; the humeral angles are more denti- 

 form and the sculpture of the elytra is different, the large 

 punctiform depressions seen in P. irregularis being almost 

 absent in this species. 



Length 9^, breadth 3^ lines. 



Wellington. Four examples were found in a ravine 

 behind the city at different times by Mr. J. H. Lewis, whose 

 name has been given to the species.
