CURCULIONIDiE. — BAGOUS. 47 



Black, opaque, head punctate ; forehead with muricated black scales : thorax 

 carinated in the middle, the sides clothed with whitish scales, the anterior 

 margin with two fascicles of black scales, behind which are three others placed 

 transversely : scutellum black : elytra with an irregular curved whitish fascia 

 at the base, and with the apex entirely whitish, deeply punctate-striated, the 

 alternate interstices with a row of elevated fascicles of scales, black towards 

 the base of the elytra, and whitish at the apex : body beneath black, sparingly 

 punctured : legs black, base of anterior femora and a ring round the others 

 whitish 5 tibise dull rufescent: anterior femora bidentate in the males. 



Not uncommon in willows and alders within the metropolitan 

 district : it likewise occurs in Devonshire, the New Forest, Dor- 

 setshire, Somersetshire, and in Norfolk and Suffolk. " Cardew- 

 mire." — T. C. Hey sham., Esq. 



Genus CCXC. — Bagoijs, Germar. 



AntenncB geniculated, 12-jointed, rather short and slender ; funiculus 7-jointed, 

 its two basal joints elongate, obconic, the remainder subperfoliated, coarctate, 

 and towards the apex gradually broader ; club large, oval. Rostrum rather 

 short, robust, arcuated : thorax subcylindric, broadly notched anteriorly and 

 a little lobate behind the eyes, which are large, ovate : elytra oblong-ovate, 

 with a prominent callosity towards the apex: legs elongate: femora un- 

 armed 5 tibiw long, curved inwardly towards the apex, which is armed with 

 a hook within : tarsi slender. 



Bagoiis may be known from the other genera of this family by 

 the brevity of its antennae, and the comparative bulk of the club, the 

 long, bent tibiae, and the slender tarsi : the species frequent damp 

 and marshy situations, and are generally incrusted with a luteous 

 matter, which renders their characters obscure, unless previously 

 washed.

 anteriorly, obsoletely punctate-striate, the interstices finely granulated, and
