FERONIDAE. 363 



the dentiform shoulders, only slightly widei- than it is at the base, they 

 are oblong-oval, moderately sinuate and narrowed near the extremity ; 

 their sculpture is very irregular, consisting of fine striae or series of 

 punctures so irregular and interrupted that they enclose unequal, chiefly 

 elongate-oval areas over most of their surface, theii- sides have coarse 

 punctiform impressions. 



Scutellum striate at base. Basal 3 joints of antennae glabrous. 

 Terminal joints of maxillary palpi elongate-oval, with obtuse apices. Legs 

 stout, posterior femora dilated and angulate underneath. Anterior tarsi 

 with their basal 4 joints cordiform and successively diminishing, the 

 outer angles of the first 3 evidently prolonged. Scutellar striae present. 



Belongs to the section bearing 2 setae at each side of the thorax, but 

 easily separable from all of its members by the distinctive sculpture. 



cJ. Length, 13 mm. ; breadth, quite 4 mm. 



Mount Dick, Lake Wakatipu. A solitary individual obtained by Mr. 

 T. Hall on the 10th March, 1914. 



3804. Pterostichus maiaei sp. nov. 



Oblong, slightly convex, glossy ; head and thorax black tinged with 

 red, the latter brilliant brassy near the basal fossae and anterior angles, 

 marginal channels viridi-aeneous ; elytral interstices fusco-cupreous, their 

 striae and sides viridescent ; tarsi and antennae piceous. 



Head, including the prominent eyes, as broad as the thoracic apex, 

 more or less irregularly and finely wrinkled, the frontal foveae not extending 

 beyond the front of the eyes. Thorax a third broader than long in the 

 middle, the base medially, the apex widely arcuate-emarginate, its sides 

 distinctly margined, rounded and widest at or just before the middle, 

 moderately sinuously narrowed towards the rectangular posterior angles ; 

 obsoletely transversely wrinkled in the male, more definitely yet finely in 

 the female, the short longitudinal basal striae usually more perceptible 

 than the apical, mesial furrow well marked but not attaining the apex, 

 basal fossae rather deep and elongate, the space between each and the 

 side sUghtly convex, the impression near each front angle quite definite. 

 Scutellum striate at base. Elytra oblong-oval, with dentiform shoulders, 

 their widest part very little broader than that of the thorax, almost thrice 

 its length, moderately sinuate-angustate behind ; scutfllar striae short, the 

 dorsal well marked, closely, finely, but distinctly punctate ; interstices 

 only moderately convex, the 3rd, 5th, and 7th shghtly broader than the 

 others, the first of these distinctly tripunctate, the last with 5 punctures, 

 both sometimes with an additional apical one, marginal sculpture irregular. 



Underside shining black, basal articulations of trochanters rufescent, 

 the terminal segment, in both sexes, quadripunctate at the apex. 



Fem. — SUghtly broader, elytral interstices less convex. 



The nearest species, P. grassator (1463), from eastern Otago, is very 

 differently and less brilhantly coloured, with reddish legs ; its elytral striae 

 are more shallow and fijier, near the suture especially, and the 3rd and 5th 

 interstices of the male are broader but less convex. 



cJ. Length, 22 mm. ; breadth, 7-7| mm. 



Kuriwai Bush, near Wyndham, Southland. Named in honour of 

 Mrs. J. H. Lewis, who also made interesting contributions to the collections 

 forwarded from Greymouth many years ago by Mr. J. H. Lewis. This 

 fine species was sent to me on the 6th October, 1914.
