CURCULIONID^. lt)5 



A. rosinse, Des Gozis, is only a small variety of A. ulmi, Desbr.j for 

 which the name of A. inversus, Bedel, has now been substituted. 



A. comari, Crotch, which is the same as A. hrunnerpennis, Curt., 

 is a small variety of A. ritbi, Herbst. 



A. conspersus, Desbr., is regarded in the Catalogue of Heyden, 

 Reitter, and Weise (190G) as a variety of A. 'pedicular ms, L. I have 

 before (Brit. Col. v. 31<^) said that it might prove to be a variety of one 

 of the allied species, and this turns out to be correct ; it is a dark form. 



Mr. E. A. Nev/bery is of opinion that A. hritannus, Desbr., which 

 is apparently synonymous with A. pubesce7is, Payk., must be regarded 

 as a good species. He writes to me that he has seen two out of the 

 three specimens taken (vide Brit. Col. v. 320) and it is impossible to take 

 them for any species but A. j^^dicidarius ; the extremely small tooth on 

 the front femora, the short red rostrum, and other characters seem, 

 however, sufficient to give specific value to the insect. 



CIONUS, Clairville. 



C. longicoUis, Ch. Brisout (Grenier. Cat. Col. de France, p. 114, 

 1863). Closely allied to C. thapsus, Fabr., but more elongate, with 

 the I'ostrum thicker, and the thorax longer, with the sides less oblique: 

 the sutural spots on the elytra are also larger. The general form, 

 moreover, is larger and more robust, with stouter legs and rostrum, 

 the latter as in C- thapsi being roughened and pubescent nearly to 

 the apex in both sexes ; the latter character separates both species 

 from C. hortulanus, which has the apical portion of the rostrum smooth 

 and shining in the female [v. G. C. Champion, Ent. Mo. Mag. xxx. 

 (2 Ser. V.) 1894, 100). L. 4-5 mm. 



Portsdown Hill, Portsea (Moncreafl), on Yerhascum thapsiis : Hare- 

 wood Forest (Tomlin). 



CEUTHORRHYNCHUS, Duval. 



C. timidus, Weise (Deutsch. Ent. Zeit. 1883, p. 325). Mr. 

 €hampion (Ent. Mo. Mag. xliv. (2 Ser. xix.) 1908, 2) says that 

 Continental authorities are unable to recognise C. chalyhcms with any 

 certainty, but as Germar expressly states that the femora are " un- 

 armed " it is evident that the species known under this name in British 

 collections has been incorrectly identified. Our insect is, in fact, the 

 ('. tiniidus of Weise, originally described from Eastern Europe, but not 

 known to be much more widely distributed. Mr. Champion has taken 

 it in abundance on tSisijmhriuvi officinale at Plumstead, Dartford, and 

 elsewhere, and it has a wide range in Britain, reaching as far as the 

 Moray district of Scotland. 



The description of C. chalyhceus in a former volume (Brit. Col. v. 

 348) must now be applied to ('. timidus. 



C. moguntiacus, Schultze (Deutsch. Ent. Zeit. 1895, p. 420). 

 This is the insect alluded to by me (Brit. Col. v. 349) as C. viridipennis, 

 Bris., and as recorded by Mr. Champion from Whitstable and from
