Tropiphorina.'] RHYNCHOPIIORA. 195 



TROPIPHORINA (Synirmina). 



This tribe contains one European genus Tropiphorus Schon. (Synir- 

 mu* Bixlel), which is allied to the Phyllobiina and Cneorrhiniua, but 

 differs in having the prosternum slightly emarginate at apex and fur- 

 nished with short hairs at the sides of the emarginatioa, 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, TropidopJiorus, 



Gernni.). 



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 antennae 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. CABiNATr S, Null. 



II. Elytra with the interstices not cristate. 



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 angle to the middle T. TOSTENTOSUS, Marxh. 



(mercvrialis, Brit. Cat.) 

 ii. Elytra with the basal external augie 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 



slight angled curve T. OBTUSTTS, Bonsd. 



T. carinatus, Mull. Oblong-ovate, black, thickly clothed with dark 

 brown coppery scales ; antennae 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, Avith the third, fifth, seventh 

 and also the eighth, ninth and tenth interstices raised and costate, and 

 the striae tine, regularly and not closely punctured ; suture much raised 

 behind ; legs pitchy. L. 6|-7 mm. 



In moss, under stones, &c. ; rarely by sweeping herbage ; very local and not com- 

 mon ; Shirley, Highgate in some numbers (Power), Faversham, Chatham, B : shnp*
