352 RHYNCHOPHOEA. \_Ceutliorrlnjncliu*. 



side sparingly and underside thickly clothed with whitish scales, 

 elytra with a lateral patch at sides and another lunulate spot before 

 apex white ; rostrum rather long and stout, autennce in part ferruginous; 

 thorax comparatively short, with the anterior margin raised, strongly 

 constricted before apex, very closely and strongly punctured, with an 

 indistinct central furrow, chiefly represented by a deep depression before 

 scutellum, lateral tubercles absent ; elytra with fine striae and broad 

 rugose interstices ; legs mostly reddish-brown, femora strongly toothed, 

 tibiae before apex armed externally with a sharp tooth. L. 2-3| mm. 

 Male with the posterior tibiae armed with a large hook, and the last 

 segment of abdomen strongly impressed. 



On Stacliys arvensis; rare; Surbiton, Surrey (Power); Claygate (Power); 

 Dagenbam, Essex ; Sheerness; Portsmouth district (Moucivatf) ; Suffolk (Garneys) ; 

 Wicken Feu (Blatcb) ; Sberwood Forest (Hardy) ; Robins Wood, Reptou (Gurneys); 

 Fallowfield, near Manchester (Chappell) ; Heysham, Lancaster (Restou) ; Northum- 

 berland district, banks of Irthing (Bold) j Scotland, rare, Solway, Forth and Clyde 

 districts. 



This species much resembles the very common Cceliodes quadri- 

 maculatus in general appearance, but, apart from the character of the 

 pectoral groove, it may be known by the tooth before apex of tibiae, and 

 also by the fact that the white marks on the elytra are nearer the 

 shoulder ; it is also larger ; it is, however, very probably passed over 

 in mistake for this species by collectors. 



C. ang-ulosus, Boh. (impressicollis, W.C. nee Gyll.). About the 

 size of 0. pollinarius, but with a longer, narrower, and subconical 

 thorax ; black, antennae, tibiae and tarsi yellowish-brown ; body covered 

 with greyish scales, which are thicker on the underside, and on the 

 elytra are fine and subrotundate ; rostrum moderately stout, thorax 

 scarcely broader than long, somewhat conical, very slightly constricted 

 towards apex, closely and finely punctured, central furrow fine, lateral 

 tubercles small and acute, anterior margin not reflexed ; elytra with 

 fine punctured striae, interstices scarcely convex, not murieate at 

 apex ; legs long and slender. L. 3-3| mm. 



In marshy districts ; probably attached to a Cruciferous plant ; very rare; Scot- 

 land, Solway district ; received from Mr. Little, taken in the North of England (8. 

 Stevens) ; in Dr. Power's collection there is a specimen from Mr. Hardy and another, 

 without locality, labelled " rugulosus, Germ., impressicollis, W. C. coil. Wollaston." 



C. picitarsis, Gyll. (tarsalis, Boh.). Ovate, black, base of antennae 

 and the tarsi reddish-testaceous ; occasionally the antennae are entirely 

 reddish ; underside diffusely covered with greyish scales, upper 

 surface without scales, but with raised greyish or brownish-grey 

 hairs which are visible if viewed sideways; head depressed between 

 eyes, rostrum rather long ; thorax broadly and strongly constricted 

 towards apex, with anterior margin strongly-raised, coarsely punctured,
