Cionus.]} 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. 34-42 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. aquatica and S. nodosa, also on Verbascum thapsus ; 
rather local, but common where it occurs; Darenth Wood, Coombe Wood, Woking, 
Cowley ; Aylsham and Potter Heigham, Norfolk ; Hastings; Winchester; South- 
ampton; New Forest; Glanvilles Wootton; Devon; Bath; Swansea; Midland 
districts, widely distributed; Manchester district, general ; Northumberland 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. (verbasci, 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 defined, so that it 
may at once be known from rubbed specimens of C. serophularie 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 antenne is longer, and in the male the last ventral 
segment of the abdomen is transversely convex and somewhat gibbous 
at apex. L. 33-43 mm. 
Marshy places; on Scrophularia nodosa and 8. aquatica; also on Verbascum ; 
very local, but not uncommon where it occurs; Hammersmith, Notting Hill and 
Battersea Fields (formerly); Merton, Barnes, Ripley, Wimbledon, Lee, Greenwich, 
Cowley, Forest Hill; Hertford ; Hastings district; Glanvilles Wootton; Swansea ; 
Bretby Wood, 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. 
GC. thapsus, F’. (similis, Munich Cat. nec Miill.). 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; antenne red; thorax small; elytra with punctured 
strie, which are concealed or almost concealed by the clothing ; legs 
dark, pubescent, tarsired. L. 81-4 mm. 
On Scrophularia nodosa and Verbascum thapsus; rare; Mickleham (Power) ; 
Surrey (Blatch) ; Portsdown, near Southsea, in May and July (Moncreaff) ; Glan- 
villes Wootton (Dale) ; Llangollen (Chappell); the record of Stephens (Ill. iv. 18) 
that the species had been ‘ taken in June on Scrophularia, rather plentifully in 
some districts, especially in a chalk pit at Northfleet,” is in the Manual (p. 218) 
apparently referred to C. horiulanus.
