Tropiphorina. | RHYNCHOPIIORA. 195 
TROPIPHORINA (Synirmina). 
This tribe contains one European genus T'ropiphorus Schén. (Synir- 
mus Bedel), which is allied to the Phyllobiina and Cneorrhinina, but 
. differs in having the prosternum slightly emarginate at apex and fur- 
nished with short hairs at the sides of the emargination, and also in the 
fact that the thorax is finely, but very distinctly, keeled on its central 
line, and that the eyes are flat and almond-shaped. Thomson includes 
the tribe under the Otiorrhynchina. 
TROPIPHORUS Schonherr (Synirmus Bedel, Tropidophorus, 
Gemm.). 
About a dozen species are comprised in this genus which appear to be 
all found in Europe ; two have generally been regarded as British, but a 
third has lately been added by Dr. Sharp; they are rather large, ovate, 
insects, with the rostrum broad but rather long, the scrobes short and 
not deflexed, and the scape of the antenne not passing the eyes, which 
are depressed ; the elytra are convex, especially behind, and very strongly 
deflexed and acuminate at apex. 
I. Elytra with the third, fifth and seventh interstices 
costate, the raised lines on the last two meeting at apex T. carinatus, Miil/, 
IJ. Elytra with the interstices not costate. 
i. Elytra at sides of base plainly projecting beyond 
the base of thorax, with the external basal angle 
projecting in front, regularly and feebly widened 
from this angleto the middle. . . . . . . . TT. TOMENTOSUS, Marsh. 
(mercurialis, Brit. Cut.) 
ii. Elytra with the basal external angie obtuse and 
truncate, coinciding with the posterior angle of 
the thorax, rather abruptly enlarged from that angle 
for one-fifth of their length and then forming a ; 
slightangled curve... « 579s V2. . T. oprusus, Boned. 
T. carinatus, Mill. Oblong-ovate, black, thickly clothed with dark 
brown coppery scales ; antenne ferruginous, club darker; rostrum stout and 
moderately long, head with a longitudinal fovea between eyes which are 
flat, very closely sculptured ; thorax slightly transverse, with sides sub- 
parallel, rounded and narrowed in front, very closely sculptured, with a 
distinct central raised line ; elytra convex, with their basal external angles 
reaching beyond the basal angles of thorax, with the third, fifth, seventh 
and also the eighth, ninth and tenth interstices raised aud costate, and 
the striz fine, regularly and not closely punctured ; suture much raised 
behind ; legs pitchy. L. 63-7 mm. :

mon; Shirley, Highgate in some numbers (Power), Favczsham, Chatham, Bishops 
Wood, Hythe; Folkestone; Hastings district; Winchester; Glanvilles Wootton ;
