RHYNCHOPHORA. 187 



CJENOPSIS, Bach. 



This genus is a very small one, containing only three species, which 

 are found in Europe, Northern Africa and Madeira ; they are allied to 

 Otiorrliym'lius and TrachypTilceus, hut may he easily known hy the close 

 strong and deep longitudinal striae on the throat ; in C. fissii-ostris the 

 deciduous mandihles are long and hooked ; the two British species differ 

 considerably in size and general appearance. 



I. Thorax as long as broad ; elytra oblong-oval ; size 



larger C. FISSIBOSTRIS, Walt. 



II. Thorax evidently transverse; elytra sub-globose; size 



smaller C. WALTONI, Boh. 



C. fissirostris, Walt. Oblong-ovate, brown, closely covered with 

 dark brown and greyish yellow scales ; rostrum short with a broad deep 

 furrow; eyes rather prominent ; antenna? ferruginous ; thorax as long as 

 broad, with the sides rather dilated and furnished with light scales and 

 squamose setae, closely sculptured, with a narrow raised central line; 

 elytra with plainly punctured striae, second interstice broader than the 

 first, apical portion with distinct erect scale-like setae ; legs ferruginous, 

 posterior femora usually with a white ring. L. 5 mm.

C. Waltoni, Schon. (>:enti-icos>is, Steph. ; Traclujphlceus Waltoni, 

 Walton). Very like a Tracliyphlceus in general appearance and quite 

 different, at first sight, from the preceding; ovate, black, thickly clothed 

 with griseous and cinereous recumbent scales, and with white erect 

 scale-like setae; head short, depressed, deeply striated and ridged above; 

 eyes small, round and prominent ; rostrum rather narrower and scarcely 

 longer than the head, deeply excavated above ; antennae rufo ferruginous; 

 thorax broader in the middle than long, considerably narrowed in front, 

 greatly dilated and rounded at the sides towards base, finely carinated, 

 thickly punctured, the punctures confluent ; elytra ample, globose or 

 globose-ovate, with regular deeply and strongly punctured striae ; inter- 

 stices narrow, convex, and coriaceous, each with erect seta3 behind ; 

 legs rather short, robust, fusco-cinereous, squarnose ; anterior tibiae un- 

 armed. L. 3-3| mm.
