Rhopalomesites. | RHYNCHOPHORA. 393 
Female with the rostrum dull, broadly and not angularly dilated 
before middle, where the antennez 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 Stereocorynes, Woll.; 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 antenne are inserted at about the middle of the rostrum 
and have a small club; the anterior coxe are narrowly distant, and the 
mesosternum is narrow and linear. 
I. Club of antenne not truncate, pubescent from 
base. 
i, Rostrum narrower and longer than head. 
1. Eyes evidently, although slightly, convex ; 
form broader; thorax constricted before

R. lignarius, Marsh. (cylindrirostris, Ol.). Oblong-cylindrical,

rostrum longer than the head, eylindrical, almost straight, thorax dis- 
tinetly and rather closely punctured with a not very evident smooth 
dorsal line, sides regularly rounded and constricted before apex; seutel- 
lum small but plainly visible ; elytra with strong punctured strie, 
interstices with a regular row of minute punctures. L. 3-3} mm, 
In decaying elms, oaks, ivy, &c.; local, 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.
