1689. E. advena, n-s. Oblong, nearly parallel, slightly con- 

 vex, nude, but little shining ; the head, most of the sides of the 

 thorax, and the scutellum reddish, elytra smoky-brown, legs, palpi, 

 and antennae fulvescent ; densely and minutely sculptured, and 

 with many short, irregular, linear impressions ; underside rufo- 

 castaneous. 



Head short and broad, with two shallow inter-ocular impres- 

 sions. Thorax very transverse, its sides finely margined, very 

 slightly curved, and narrowed anteriorly, the base a little sinuous, 

 its middle portion very slightly prominent, so that the large scutellum 

 is wholly exposed ; the sculpture of the front part more punctiform 

 than on the disc. Scutellum broadly triangular. Elytra with acute 

 apices ; each wing-case with a median row of very small punctures, 

 and some others beyond. 



^ . Three basal joints of front tarsi strongly expanded, quite 

 transverse, third not distinctly emarginate at apex, fourth narrowed 

 at the base. 



Length, 2^2f lines; breadth, i-i^. 



Found in brackish water on Mokohinau Island by Mr. P. Stewart- 

 Sandager.

Adolopus. 



1690. A. vicinus, n.s. Shining, black, margins and legs rufes- 

 cent, tarsi, antennae, and palpi fulvous. 



Head finely punctured. Thorax transverse, its sculpture like that 

 of the head. Elytra striate-punctate, the series of punctures obso- 

 lete on the dorsum, but rather coarse near the sides and apices, the 

 sutural strias deep behind, but disappearing near the middle. Under- 

 side opaque, blackish, all but the shining middle part of the meta- 

 sternum finely sculptured and pubescent. 



Eesembles A. altulus (No. 158) ; differs in outline, being narrower 

 and, therefore, more oblong ; the thorax not so much curvedly 

 narrowed towards the front ; the elytral margins not explanate 

 behind.

Discovered at the Thames by Mr. I. Adams, B.A. 



1 69 1. A. rugipennis, n.s. Shining, nude, pale-castaneous, 

 legs, antennae, and palpi yellowish, club infuscate. 



Head finely punctured, interstices minutely sculptured. Thorax 

 very transverse, finely marginated laterally, strongly and rather 

 curvedly narrowed towards the front ; very finely and rather dis- 

 tantly punctated. Scutellum tvl^ngiila^v, minutely punctured. Elytra 

 short, lateral margins distinct except near the apices ; striate-punc- 

 tate, the sculpture of the discoidal portion, however, much less 

 developed, and consisting almost entirely of fine punctures and 

 wrinkles, the space on each side of the scutellum obhquely depressed. 

 TibicB smooth, spinose externally.
