270 RHYNCHOPHORA. [ Brirrhinus. 
Marshy places, especially about river banks; on sallows and Cyperacee; oceasion- 
ally found in flood re‘use; not common; Wimbledon, Gravesend, Strood, Chatham, 
Barking, Sunbury, Dagenham (E-sex) ; Norfolk; Dover; Hayling Island; Bristel ; 
Crymlyn Bay, Swansea; Bewdley, Brosely, Repton and other midland localities ; 
Lincoln, banks of Witham ; Liverpool district, flood refuse from the Alt and Leasowe 
embankment; Lancaster; Carlisle; Norchumberland and Durham district, ‘l'wizell, 
near Gilsland; Scotland, maritime, very local, Solway district. 
E. acridulus, L. Black, rather dull, or moderately shining, 
sparingly clothed with greyish squamose pubescence, which is thicker 
at sides of thorax and on scattered patches on elytra ; head and rostrum 
punctured ; antenne ferruginous; thorax nearly as long as broad, 
coarsely and deeply punctured, with a more or less distinct smooth 
central line; scutellum pitchy ; elytra oval, with rather deep crenate 
striz, much broader at base than thorax, with shoulders well marked, 
sides narrowed before apex, interstices rugose ; legs red, with the femora 
usually black ; sides of abdomen with greyish scales. L. 33-54 mm. 
Marshy places; in moss, at roots of grass, on Carex, &c.; common and generally 
distributed throughout the kingdom as far north as the Shetland Islands. 
E. ethiops, fF. Somewhat elongate, or elongate-ovate, deep black, 
shining, glabrous; head and base of rostrum distinctly punctured, the 
latter smooth, even and shining; antenne ferruginous; thorax about 
as long as broad, with the sides slightly rounded, rather strongly but 
somewhat diffusely punctured on disc, more closely at sides; central 
line impunctate but not raised ; scutellum small, smooth and shining; 
elytra with .deep punctured striz, interstices finely punctured; legs red 
or pitchy red ; varieties occur in which the whole body, or at all events 
the elytra, are pitchy red, and in some specimens the legs are black. 
L.5-7 mm, 
Marshy places ; in moss; on Spurganium ramosum; by sweeping herbage on the 
edge of drains, &c.; extremely rare in England ; Askham Bryant, Yorkshire (Stephens); 
Askham Bog, York (stephens) ; Scotland, rare, Solway, Tweed and Tay districts ; 
Ireland, apparently locally common; Mr. Jolnson tells me that he has in some 
years taken large numbers in the Mullinures, near Armagh, in autumn on Sparganium, 
and in spring in moss; in 1890 it has, however, been extremely scarce and only one 
specimen has been found by him, ia moss from Lowry’s Lough, a locality in which it 
has not previously occurred. 
THRYCGENES, Bedel (Lrirrhinus, auct. pars.). 
This genus has been formed by Bedel to include 7. festuew, T. Nereis 
and 7. scirrhosus, which have usually been regarded as belonging to 
Frirrhinus Schonh.,; they differ in having the prosternum truncate in front 
and bordered by a well-marked transverse line, the elytra with the 
suture at least clothed with short scales, and the eyes rounded and sub. 
convex ; the three species known are found in marshy places in Europe 
and Northern Asia ; 7’. fesfuce lives in the stems of various Cyperacec: 
(Scirpus and Carex); its larva, observed by Boie, bores a gallery in the
