420 Major T. Bioun on neio 



not reaching the front marghi. Scutellum finely striate. 

 Elytra oblong, humeral angles rounded and not dentiform, 

 moderately curvedly narrowed, but hardly at all sinuate 

 posteriorly ; they are nearly plane, and have finely and 

 closely punctured but not deep strise; interstices rather flat, 

 the third tripunctate ; the marginal sculpture well marked, 

 the seventh strise very fine. 



The mandibles are rather short, but strongly curved and 

 acute at the extremity. Femora simple. Thorax bisetose at 

 the sides, last ventral segment also. 



P. oscillator, Sharp, is certainly the nearest ally. This 

 species differs in having more shallow, but distinctly though 

 finely punctured elytra! striaj, scored scutellum, &c. In my 

 specimen of P. oscillator the lower sides of the head, between 

 the eyes and middle of mandibles, are ex})anded and rufescent, 

 and in this respect resemble the Antarctic genus Loxomenia. 

 In P. lepidulus the dilatation is normal and does not extend 

 beyond the base of the mandibles. 



(^ . Length 6 ; breadth 2 lines. 



West Plains, Invercargill. A single specimen from Mr. A, 

 Philpott. 



Pterostichus chalmeri, sp. n. 



Elongate-oblong, glossy black ; the legs and basal four 

 joints of antennge rut'o-piceous, remaining joints infuscatc red ; 

 tarsi and palpi piceo-rufous. 



Head (eyes inclusive) rather narrower than front of thorax, 

 frontal fovese short, not extending backwards to the eyes ; 

 labrum large, widely incurved : eyes moderately prominent. 

 Thorax a fourth broader than long, widest before the middle, 

 moderately rounded, a good deal narrowed backwards, poste- 

 rior angles rectangular, the anterior rounded, apex widely 

 but slightl}' incurved ; base subtruncate, being only a little 

 emarginate at the middle ; disk slightly convex, with feeble 

 yet quite perceptible transverse strise, the curvate frontal 

 impression shallow ; basal fossae broad, with a second smaller 

 outer fovea united to each ; discoidal furrow distinct but not 

 attaining the apical margin. Scutellum deeply striate at 

 base. Elytra oblong; humeral angles obtusely dentiform; 

 they are but little narrowed and only slightly sinuate poste- 

 riorly ; they are distinctly and regularly punctate-striate, the 

 striae are deep but not distinctly punctured at the base, the 

 marginal punctures are well marked ; interstices slightly 

 convex, simple. 



Leys stout, hind thighs angulate and minutely dentifornji
