RHYNCHOPHORA. 



325 



circular spot before middle is bounded behind, and the apical spot 

 before and behind with small whitish patches ; legs black, tarsi more or 

 less ferruginous. L. 3| i| mm. 



Male with the anal segment of the abdomen furnished with a trans- 

 verse band of yellowish hairs and subemarginate at apex. 



On Scrophularia, especially S. aqvatica and S. nodosa, also on Verbascvm thapsvs ; 

 rather local, but common where it occurs; Darenth Wood, Coombe Wood, Woking, 

 Cowley ; Aylshara and Potter Heighain, Norfolk; Hastings; Winchester; South- 

 ampton; New Forest; Glanvilles Wootton ; Devon; Bath; Swansea; Midland 

 districts, widely distributed; Manchester district, general; Northumberlaqd and 

 Durham district ; Scotland, common on Scrophularia nodosa, Solway, Forth, 

 Tay and probably other districts ; Ireland, near Belfast, and most likely general. 



C. tuberculosus, Scop, (verbasri, F.). This species is so like the 

 preceding in general appearance that it does not require a separate 

 description ; it may easily be distinguished by having the central part of 

 the thorax quite- bare, and the sides thickly covered with yellowish 

 white scales, the lines of separation being sharply denned, so that it 

 may at once be known from rubbed specimens of C. scrophularice in 

 which the pubescence of the disc of thorax is abraded ; the meta- 

 sternum moreover and the first half of its episterna are without scales ; 

 the club of the antennae is longer, and in the male the last ventral 

 segment of the abdomen is transversely convex and somewhat gibbous 

 at apex. L. 3|-4| mm. 



Marshy places ; on Scrophularia nodosa and S. aquatica ; also on Verla.tcum ; 

 rery local, but not uncommon where it occurs; Hammersmith, Xotting Hill and 

 Battersea Fields (formerly) ; Merton, Barnes, Ripley, Wimbledon, Lee, Greenwich, 

 Cowley, Forest Hill; Hertford; Hastings district; Gianvilles Wootton; Swansea; 

 Bretby Wooil, near Repton (W. Garneys) ; Scotland, very rare, Forth district, 

 " Dollar, Mr. J. T. Syme," Murray's Cat. ; it is possible there may be some mistake 

 as to the latter record. 



C. thapsus, F. (similis, Munich Cat. nee Mull.). Fuscous-brown, 

 clothed throughout unevenly with a greenish ashy pubescence, elytra 

 with the alternate interstices slightly elevated, and tessellated with 

 somewhat ill-defined lighter and darker patches, which are more marked 

 in some specimens than in others, and with two circular black velvety 

 spots, one before middle and another before apex, the latter being as a 

 rule smaller than the former ; rostrum moderately stout, not narrowed 

 towards apex ; antennae red ; thorax small ; elytra with punctured 

 striae, which are concealed or almost concealed by the clothing; legs 

 dark, pubescent, tarsi red. L. 3^-4 mm. 



On Scrophularia nodosa and "Ferbascum thapsus ; rare ; Mickleham (Power) ; 

 Surrey (Blatch) ; Portsdown, near Southsea, in May and July (Moncreaff) ; Glan- 

 villes Woottou (Dale) ; Llaugollen (Chappell); the record of Stephens ^111. iv. 18) 

 that the species had been " taken in June oil Scrophularia, rather plentifully in 

 some districts, especially in a chalk pit at Xorthfleet," is in the Manual (p. 218) 

 apparently referred to C. horiulanus.
