ANCHOMENIDAE. 599 



sponge-like vesture underneath along the middle but fringed with setae 

 at the sides. Apical ventral segment at the extremity with a single 

 setigerous puncture at each side of the middle. These characters, in 

 conjunction, distinguish this from the other species of Anchomenidac. 



o. Length, 13 mm. ; breadth, -if mm. 



Rotoiti, Nelson. Named after its discoverer, Mr. T. Hall. One male 

 only; 26th July, 1916. 



Group Feronidae. 

 Pterostichus Bonelli. Man. N.Z. Coleopt., p. 31. 



4161. Pterostichus fenwicki sp. nov. 



Subdepressed, elongate-oblong, shining ; black, palpi, antennae, and 

 tarsi rufo-j)iceous. 



Head, and mandibles, nearly as long as thorax, rather narrower, with 

 elongate frontal impressions and a few fine interocular rugae. Thorax 

 as long as broad, subquadrate, slightly wider before the middle than 

 elsewhere, very gradually narrowed behind, posterior angles only very 

 slightly prominent, base and apex a little incurved ; discal furrow well 

 marked but not reaching the front, basal fossae large and elongate, 

 duplicate, the inner the larger, both extending to the basal margin. 

 Scutellum striate at base. Elytra rather more than double the length 

 <jf thorax, slightly wider than it is at the base, with dentiform shoulders, 

 evidently sinuate-angustate near the extremity ; they are moderately 

 finely punctate-striate, the first and second as well as the fifth and sixth 

 are somewhat disorganized and appear subcatenulate, the fourth and seventh 

 interstices are a little broader than the others and become irregular or 

 subcatenulate posteriorly, the lateral punctation is fairly regular and coarse. 

 Femora stout, the anterior and posterior particularly, the latter obtusely 

 angulate underneath. 



Mesosternura closely and finely punctured, remainder of underside 

 nearly smooth ; the terminal ventral segment with a single apical puncture 

 at each side of the middle. 



Larger than P. impiger (1563), Avithout occipital punctation, the sab- 

 apical sinuosities of elytra more abrupt and deeper. In P. edax (2332) 

 the thorax is rather shorter with more rounded sides. Its systematic 

 position is near these in Section II, having two setigerous punctures on 

 each side of the thorax. 



S- Length, 14 mm. ; breadth, 4| mm. 



Hump Ridge, Southland; 20th January, 1916. One example, from 

 Mr. Cuthbert Fenwick, of Dunedin, whose name it bears. 



Group ZoLiNT. 

 Zolus Sharp. Man. N.Z. Coleopt., p. 1000. 



4162. Zolus labralis sp. nov. 



Subovate, elongate, moderately convex and nitid ; piceo-niger, the 

 suture, and lateral margins of elytra and thorax, the base of the latter, and 

 the mandibles rufescent ; legs, antennae, and palpi more or less light rufo- 

 castaneous. 



Head nearly as long as thorax and, including the moderately prominent 

 eyes, as broad as its apical portion, the interocular impressions elongate
