PSELAPHIDAE. 517 



subquadrate, rather broader and a third longer than thorax, a little 

 narrowed towards the base ; sutural striae well mark d^ foveiform at the 

 base, intrahumeral impressions moderately deep and indis inctly pro- 

 longed. Hind-body rather longer than elytra, nearly as broad, curvedly 

 narrowed but not acuminate behind, first visible segment with a sublunate 

 basal impression, but hardly any longer than the next. Legs elongate, 

 tibiae somewhat arched externally. Antennae of normal structure, like 

 those of 3725. 



Ventral segments 2— t subequal, fifth rather shorter, truncate ; sixtl' 

 longer than fifth, curvedly narrowed behind. 



Not so narrow as E. vidamoides, its head less oblong, the thorax shorter 

 and rather broader before the middle. It is less fusiform than E. ovicollis, 

 with a larger and broader head.

Mount Hope, Nelson ; 7th March, 1915. A single specimen from 

 Mr. T. Hall. 



Obs. — E. caudatus (2482) erroneously treated by M. Eaffray (Gen. Ins. 

 (Wytsm.), Pselaphidae, p. 112) as the female of E. aUocephalus (1890). 

 I removed my remaining specimen of that species (2482) from the cardboard 

 and carefully examined it under the microscope. Its ventral structure is 

 as follows : — 



Male. — Second segment distinctly longer than third, fourth almost semi- 

 circularly emarginate, much shorter than its predecessor ; fifth similar to 

 fourth, much shorter in the middle, its sides clasping the basal portion of 

 the sixth, which is about four times the length of the fifth and gradually 

 narrowed towards the extremity. 



Male. — E. aUocephalus (1890). Ventral segments 2-4 successively 

 ■diminish, fourth widelj^ emarginate ; fifth longer than fourth, transversely 

 impressed, semicircularly emarginate and almost wholly enclosing the 

 broadly oviform sixth. 



Male. — E. acuminatum (1891) Ventral segments 2-4 diminish ; fifth 

 shorter than fourth, truncate behind ; sixth free, about double the length 

 of fifth. 



BKACHYGLUTINI. 



Eupinogitus gen. nov. 



Body moderately elongate and convex, interruptedly narrowed anteriorly, 

 elytra and hind-body, together, quite oviform. 



Head rather large, slightly narrowed in front of the prominent eyes, 

 curvedly narrowed behind them, vertex distinctly bifoveate. Thorax 

 oviform, with an angular median impression near the base, and an oblique 

 stria proceeding from it to the deep fovea at each side. Elytra rather 

 broader than long, curvedly narrowed towards the base, with well-marked 

 sutural and dorsal striae. 



Maxillary palpi stout and elongate ; basal joint minute, second elongate, 

 slender near the base, clavate at the extremity ; third subglobular and thick ; 

 fourth truncate at the base, elongate-oval and acuminate, with a minute 

 acicular terminal appendage. Antennae eleven-articulate in both sexes. 

 Mandibles dentate inwardly. 



Male. — Underside of the head with a longitudinal carina. Metasternum 

 truncate between the widely distant posterior coxae, the depression along 

 the middle with obtusely elevated lateral borders. Basal ventral segment 

 concealed by the femora, ciliate behind ; second nearly as long as the third
