CURCULIONID-^.. — CI ONUS. , 17 



I possess a single example of this insect, which was captured, I 

 believe, in Norfolk : it inhabits the roots of the Antirrhinum Linaria, 

 the pupa being- enveloped in a cocOon resembling a gall. 



Genus CCLXXIX.—Cionus, Clairville. 



Antenna; gemm\a.teA, 10-jointed, short, somewhat slender, funiculus 5-jointed, 

 Its basal joint obconic, the second elongate-subclavate, the remainder short, 

 subtruncate at the apex, club oblong-ovate, indistinctly articulated. Rostrum 

 elongate, rounded, curved : thorax small, transverse, narrowed anteriorly, the 

 base and apex subtruncate : elytra large, convex, quadrate-ovate, covering the 

 abdomen: body subglobose: legs moderate; femora clavate, dentate: tibiw 

 truncate at the apex, unarmed. 



The species of this elegant genus may be known by their sub- 

 globose form, united to their 10-jointed antenna, of which the third 

 joint (or second of the funiculus) is elongate- clavate, their small 

 thorax, and beautifully tessellated ample elytra:— they subsist both 

 in their larva and imago states upon plants, especially those of the 

 genera A^erbascum and Scrophularia. In July, 1827, I captured a 

 single example of each species in a garden at Ripley, upon the 

 only Verbascum therein. 



Sp. 1. Scrophulariae. Nigro-fuscus, thorace toto Jlavescente villoso, elytris 

 striatis, interstitiis alternis elevatiorihvs airo alhoque tessellatis, maculis duahus 

 suturalibus magnis atro-holosericeis. (Long. corp. 2^—3 lin.) 



Cu. Scrophulariae. JdnnL~Bon. ii. ;,/. 60.-Ci. Scrophularia. Steph. Catal. 

 150. No. 1517. 



Blackish brown : the thorax entirely and breast densely clothed with a yel- 

 lowish down: elytra punctate-striated, the alternate interstices elevated with 

 subquadrate velvety black spots and narrow white ones alternating, the 

 suture similarly tessellated, but, in addition, with a large oblong-ovate deep- 

 black spot, to which a white one is appended behind, at the base, and a 

 smaller one towards the apex, augmented both in front and behind by a 

 white one: legs black: tarsi rufescent. 



Found in June and July, chiefly on the Scrophularia nodosa, 

 also on the Verbascum Thapsus in plenty :— also frequent upon 

 garden plants of the same and other genera. " On Scrophularia 

 nodosa, common (near Swansea), and sometimes on Scrophularia 

 aquatica. Mr. Jeffreys has observed it abundant on Buddtea glo- 

 bosa."— Z. W. Dilhmjn, Esq,
