remark applies to more cases than one, when, in describing A. con- 

 spersus as very near A. pedicularius, he mentions a few characters, 

 none of them very striking, and then says, " les autres caracteres 

 signales dans ]a description de I'auteiir sont illusoires" (Faune. Col. 

 du Bassin de la Seine, Ehynchophora, p. 425). I have found the 

 genus the most difficult among the British Curculionidce, and am not 

 at all sure that the following notes are correct ; Des Gozis' new 

 species, A. Eosince, appears to be distinct, and I think that A. comari 

 should count as a separate species ; nothing satisfactory appears to be 

 known of A. hritannus, and it was probably only a variety of an allied 

 species. I do not feel at all sure of the specific value of A. conspersus, 

 but I have not seen enough specimens to form a judgment upon: I 

 shall be very much obliged for any notes or corrections. 



I. Elytra with a transverse or yerj slightly oblique band of white pubescence on 



each, behind middle, sometimes meeting at suture ; colour, red or ferru- 

 ginous, sometimes darker before the elytral band than at apex. 

 i. Thorax and elytra comparatively flat, if viewed sideways, sides of the former 

 slightly rounded ; elytra with a little oblong tubercle or small promi- 

 nence at the base of the third interstice. 



1. Teeth of anterior femora very strong ; rostrum longer and more slender, 



with the antennse inserted further from apex ; anterior tibiae very 

 deeply sinuate on their interior margin towards base. 



A. Length, 85 — 4 mm. ; interstices of elytra dull, distinctly rugose 



transversely A. ulmi, De Gr. 



B. Length, 2 — 2J mm. ; interstices of elytra rather shining, com- 



paratively smooth A. RosincB, Des Gozis. 



2. Teeth of anterior femora evidently smaller and less strong ; rostrum 



shorter and thicker, with the antennae inserted nearer to apex ; 

 anterior tibiae almost straight, and scarcely sinuate on their 



interior margin A. pedicularius, L. 



ii. Thorax and elytra separately convex, if viewed sideways, sides of the former 

 strongly rounded ; elytra without tubercle or prominence at the base 

 of the third interstice ; interstices rather shining, almost smooth... 



A. Chevrolati, Desbr. 



II. Elytra with scattered yellowish or whitish pubescence, which, however, does not 



form bands ; colour, pitchy-brown or pitchy-black, with the legs more or 

 less testaceous A. conspersus, Desbr. 



III. Elytra with a strongly oblique band of whitish pubescence on each, sometimes 



meeting at suture ; colour, fuscous or pitchy-black, with the legs more or 

 less pitchy or pitchy-ferruginous A. pomorum, L. 



IV. Elytra without distinct bands or markings of pubescence, but with the pubes- 



cence fine and scanty, and evenly distributed over the whole surface, which 

 appears, unless closely examined, to be almost glabrous.
