270 RHYNCHOPHORA. 



Marshy places, especially about river banks ; on sallows and Cyperacete; occasion- 

 ally found in flood refuse ; not common ; Wimbledon, Gravesend, Strood, Cliatham, 

 Barking, Sunbury, Dagenham (E<sex) ; Norfolk; Dover; Hayliug Island ; Bristol; 

 Crymlyn Bay, Swansea; Bevvdley, Brosely, Rcpton and other midland localities; 

 Lincoln, banks of Withiun ; Liverpool district, flood refuse from the Alt and Leasowe 

 embankment; Lancaster; Carlisle; Northumberland and Durham district, Twizell, 

 near Gilsland ; Scotland, maritime, very local, Solway district. 



E. acridulus, L. Black, rather dull, or moderately shining, 

 sparingly clothed with greyish scjuamose pubescence, which is thicker 

 at sides of thorax and on scattered patches on elytra ; head and rostrum 

 punctured ; antennae 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 

 strise, 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. 3|-5| 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. aethiops, F. Somewhat elongate, or elongate-ovate, deep black, 

 shining, glabrous ; head and base of rostrum distinctly punctured, the 

 latter smooth, even and shining ; antenna? ferruginous ; thorax about 

 as long as broad, with the sid. j s 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 striae, 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 Spargcmium ramosum , by sweeping herbage on the 

 edge of drains, &c.; extremely rare in England ; Askham Bryant, Yorkshire (Stephens); 

 Askham Bog, York (Stephen*) ; Scotland, rare, Sol way, Tweed and Tay districts ; 

 Ireland, apparently locally common ; Mr. Johnson tells me that he has in some 

 years taken large numbers in the Mnllinures, 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, in moss from Lovvry's Lough, a locality in which it 

 lias not previously occurred. 



THRYOGENES, Bedel (Erirrhmus, auct. pars.). 



This genus has been formed by Bedel to include T. festucce, T. Nereis 

 and T. scirrhosus, which have usually been regarded as belonging to 

 Erirrhmus Schoriti.; 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 ; T.festucce lives in the stems of various Cyperacete 

 (Scirput and Carex) ; its larva, observed by Boio, bores a gallery in the
