American mainland. They are elongate, narrow, minute, depressed forms, with 



a 







strongly exserted head and a 5-jointed funiculus. The New Zealand insects forming 

 the types of JDiadimorpha, Broun, seem to me to be scarcely separable from 



Stenotrupis. 



(Tab. I. fig. 16.) 



1. Stenotrupis ovaticeps, sp. n. 



EloDgate, very narrow, depressed, shilling, rufo-testaceous, the eyes and the space between them black ; 

 sparsely, very finely pubescent, the pallid hairs becoming longer and more conspicuous towards the apex 

 of the elytra. Head strongly exserted, ovate, sparsely punctate ; rostrum a little longer than the head, 

 slender, slightly widening outwards, sparsely punctate, the antennae inserted at about the basal third, 

 the funiculus and scape slender. Prothorax a little longer than broad, subcorneal, constricted in front, 

 the sides rounded at the base ; sparsely impressed with rather coarse oblong punctures. Elytra elongate, 

 widening to a short distance below the base and subparallel thence to near the apex, the apex itself 

 bluntly rounded; closely seriate-punctate, the interstices flat and alutaceous. Beneath somewhat 

 coarsely, rather sparsely punctate. Legs moderately stout.

The species are all of small size, subcylindric or conico-cylindric in sh
