easily distinguish this from pygmaus (lucorum, D. and S.). In general 

 appearance it looks more like a narrow Tetraplileps, but the long 

 antennae and generic characters at once separate it from that genus. 

 I believe I am right in referring this to Renter's species. 



Nabis Poweei, sp. n. 



Elongate, sides of the body sub-parallel, pale ochreous. Sead 

 with a dull pale brown stripe on each side and in the centre, and with 

 a brown Y-shaped mark at the base. Thorax elongate, sides nearly 

 straight, with a central line and various small markings on the disc, 

 brown ; scutellum with a central line, brown ; elytra very short, 

 truncate, very slightly rounded at the corners. Body finely pubescent, 

 very elongate in both sexes, ochreous, becoming reddish towards the 

 margin, sides not foliaceous, with a black central line, and a brown 

 line outside this on each side, but not quite touching it ; legs ochreous, 

 spotted with brown. 



Length, 6 lines. 



Hab. Chobham, Surrey. Taken by sweeping in a marsh. 



Allied to -ZV. limhatiis, but rather larger, and at once distinguish- 

 able by the sides of the body not being foliaceous, and in the ? being 

 sub-parallel as in the ^ ; whereas in Umbatus the body of the ? is 

 much widened, and with the sides rounded. The eyes are also less 

 prominent and further apart ; the rudimentary elytra are much less 

 rounded at the apex, and the body is differently coloured. The hamus 

 of the male genitalia is larger and differently shaped. 



It is also allied to N. lineatus, Dahlb., a species unknown to me ; 

 but, according to Renter's description, the present species appears to 

 to be distinct, especially in the narrow body of the $ .
