RHYNCHOPHOBA. 393 



Female with the rostrum dull, broadly and not angularly dilated 

 before middle, where the antennae are inserted, sides of rostrum raised 

 and rather shining at the dilated portion. 



In old holly trees ; also occasionally in beech ; very local, but not uncommon where 

 it occurs ; Mount Edgcumbe Park, near Plymouth (rather common) ; Ilfracombe 

 (remains, J. J. Walker) ; Scotland, very rare, Clyde and Argyle districts; it is espe- 

 cially an Irish species, where it has been found in greater or less abundance in 

 several localities ; Powerscourt, near Dublin ; Tollymore Park, Westport, co. Mayo ; 

 Belfast district ; Bantry, June, 1886, abundant under dead beech bark (J. J". 

 Walker). 



RHYNCOLUS, Steph. 



This genus has been differently constituted by different authors, and, 

 as here constituted, includes Stereocoryiies, \Voll.; it contains more than 

 fifty species ; fifteen of these occur in Europe and four in Britain ; they 

 most closely resemble the two following genera, from which they may 

 be known by having the scutellum small but distinct ; the rostrum is 

 not dilated at apex and the scrobes are narrow and continued beneath 

 the eyes : the antennae are inserted at about the middle of the rostrum 

 and have a small club ; the anterior coxae are narrowly distant, and the 

 mesosternum is narrow and linear. 



I. Club of antennae not truncate, pubescent from 



base, 

 i. Rostrum narrower and longer than head. 



1. Eyes evidently, although slightly, convex ; 

 form broader ; thorax constricted before 



apex E. JJGNARITTS, Marsh. 



(cylindrirosMs, Ol.) 



2. Eyes almost flat ; form narrower and more 

 elongate ; thorax not constricted before 



apex R. GEACILIS, Rosenh. 



ii. Rostrum as broad as, and almost shorter than, 



head R. ATEB, L. 



(chloropus, F.) 



II. Club of antenna? truncate, pubescent only at 

 apex ; eyes depressed, on a level with the 



surrounding surface (Stereocorynes, Woll.) . . R. TBUNCOETTM, Germ. 



XL. lig-narius, Marsh, (cylindrirostris, 01.). Oblong-cylindrical, 

 pitchy black, glabrous, rather shining, antennae and legs dark ferruginous ; 

 rostrum longer than the head, cylindrical, almost straight, thorax dis- 

 tinctly and rather closely punctured with a not very evident smooth 

 dorsal line, sides regularly rounded and constricted before apex ; scutel- 

 lum small but plainly visible ; elytra with strong punctured striae, 

 interstices with a regular row of minute punctures. L. 3-3^ mm. 



In decaying elms, oaks, ivy, &c. ; L -cal, but common in some districts ; London 

 district, Kent, Surrey, and most of the southern counties, generally distributed and 

 common ; Devon, scarce ; Windsor ; Llangollen ; I have no record from the Midland 

 counties or in fact from any place north of the London district, except " Scotland, 

 very rare, Solway district (Sharp)"; it most probably, however, occurs in some of 

 the intervening districts.
