Species of New- Zealand Coleoptera. 413 



present species the seventh stripe consist of a combination of 

 over twenty rather fine punctures and impressions. This will 

 enable the student to distinguish the species. 



S • Length 81-9 ; breadth 2|-3 lines. 



Takuratahi and Mount Pioldsworth. Two males from 

 Mr. G. V. Hudson's collection. 



Pterostichus oneroaensis, sp. n. 



Black, glossy ; tibiae and antennae nigro-piceous ; tarsi 

 rafo-piceous ; labrum and mandibles also black. 



The description of P. sandageri (no. 1776) applies exactly 

 to this, with the following exceptions : — 



The elytral interstices are transversely marked with acicu- 

 late impressions and the two large punctures on the third are 

 absent. The prosternal process is broadly grooved and the 

 metasternum is similarly impressed longitudinally. The legs 

 are more robust, the intermediate femora are much swollen 

 underneath, so as to appear more emargiuate towards the 

 apex ; the tibiae of the same pair have their hind or outer 

 angles produced as a stout spiniform process. This last 

 character, however, is also present in P. sandageri. 



There are two setigerous punctures on each side of the 

 thorax — one before the middle, the other at the hind angle — 

 and the same number at each side of the middle, at the apex, 

 of the last ventral segment. It belongs to the Trichosternus- 

 like section (see Man. N. Z. Coleopt. p. 986). 



<J . Length 12^ ; breadth 4 lines. 



Te Oneroa (Mr. P. Seymour) ; Invercargill (Mr. G. V. 

 Hudson). One specimen from each. 



Pterostichus flectipes, sp. n. 



Suboblong, moderately convex, shining cupreous black; legs 

 and antennae piceous. 



Head convex, frontal impressions distinct, and with a 

 series of fine longitudinal interocular striae. Thorax 3 lines 

 in width by 2j in length, base and apex much incurved, 

 widest near the middle, moderately curved forwards, narrowed 

 and slightly sinuate towards the rectangular posterior angles, 

 marginal channels of almost equal width throughout; median 

 groove distinct from base to apex, basal fossae large ; across 

 the disk there are several feeble aciculate impressions. 

 Scutellum striate. Elytra oblong-oval, shoulders dentiform 

 but not proponent ; with finely punctured striae ; interstices 

 slightly convex, the third with two, the seventh with five 

 punctures.
