species 0/ Pselaphidse /?*om New Zealand. 699 



base connecting the small, shallow, subrotundate lateral fove?e 

 with the small punctiform central one. Elytra oblong, 

 ratlier broader and obviously longer than the thorax ; with 

 "well-marked sutural strige, which are foveiform at the base, as 

 are the distinct, moderately elongate, dorsal impressions. 

 Hind body as broad as the elytra, but quite a third shorter, 

 segments 3-5 deflexed, the second as long as the first, the 

 latter slightly medially impressed at the base. 



Antennce scarcely as long as the head and thorax, second 

 joint nearly oviform^ hardly longer than broad, as large as 

 the visible portion of the first ; the others, including the large 

 distinctly pubescent terminal one, similar to those of 

 A. claviger. 



This species may be recognized at once by the dark, elon- 

 gate, glossy elytra, impressed basal dorsal segment, and 

 shorter antennae. A. claviger is of an almost uniform light 

 chestnut-red, and is without any perceptible central fovea in 

 the transverse depression of the thorax. 



Length quite 1 ; breadth ^ mm. 



Hovvick, near Auckland. I have only succeeded in finding 

 one specimen. 



3386. Alloplectus subca^cus, sp. n. 



Nitid, light castaneo-rufous; elytra and abdomen sligiitly 

 darker, yet quite rufescent and rather dull ; legs and antenna? 

 somewhat fulvescent ; pubescence greyish, depressed and 

 distinct. 



Head nearly as long as the thorax, subtrigonal, its hind 

 angles obtusely rectangular, indistinctly punctate, the frontal 

 foveas and linear basal impression rather shalloAv. Eyes 

 minute. Thorax suboviform, rounded and widest before the 

 middle, only slightly longer than broad, its punctation 

 shallow and not close, but quite discernible under a good 

 lens ; lateral fovea? indistinct, the central one somewhat 

 angulate and forming part of the transverse basal impression. 

 Elytra rather broader and slightly longer than the thorax, 

 feebly curvedly narrowed towards the base ; dorsal impres- 

 sions punctiform at the base, rather small and indefinite, 

 sutural striaj linear, also punctiform at the base. Hind body 

 as broad and nearly as long as the elytra, the first segment 

 with a short median basal depression and equalling the 

 second in length, the others deflexed. 



Antennce nearly as long as the head and thorax, second 

 joint subrotundate, as thick as the short exposed portion of 

 the basal one ; third just perceptibly longer than broad,
