188 CURCULIONIDA\ 



II. Second joint of posterior tarsi distinctly 

 shorter than first ; elytra with simple striaj 

 and variable markings, which usually take 

 the form of transverse spots, but are 

 sometimes altogether wanting ; hind tibiae 

 shorter and thicker, less regularly curved, 

 with only a moderate apical spur . . B. claudicans, Boh. 



B. lutulosus, Gyll., and B. diglyptus, Boh., form a small group 

 by themselves, distinguished by the short tarsi. They are both rare, the 

 latter extremely so, having only occurred at Burton-on-Trent (Harris), 

 Gipping near Ipswich (Morley), and Sutton Broad (Donisthorpe). 



B. lutosus, Gyll. This species is omitted by Mr. Newbery, who 

 says that the large form of B. glabrirostris has been doing duty for it 

 in our collections. Mr. Edwards, however (Ent. IVto. Mag. xxxviii. 

 (2 Ser. xiii.) 1902, 240), reinstates the species, and says that his single 

 specimen (taken on Wretham Heath, Norfolk) agi^ees not only with 

 the descriptions, but with authentic specimens examined by him, except 

 that the sutural stria is not so conspicuously deeper than the 

 remainder. He has since taken further specimens. 



The characters given by Bedel (Faune Col. Bassin de la Seine, vi. 

 p. lOG) for lutosus, Gyll., and glabrirostris, Herbst, are as follows : 



Hind body attenuated in a rather long beak. 



Sculpture finer ; granules of the elytra 



more numerous, visualy 4x4 upon the 



base of the first interstice ; 8rd in- 

 terstice not raised, with a yellowish, 



hardly defined spot . . . . B. lutosus, Gyll. 



Hind body somewhat abruptly declivous 



behind. Sculpture coarser ; granules of 



the elytra less numerous, usually 3x3 



upon the base of the first interstice ; 



3rd interstice with a whitish well-defined 



spot. Tarsi sometimes black (var. ^ 



nigritarsis, Thoms.), sometimes red . B. glabrirostris, //erJsf. 



(Ittiidentus, Gyll.). 



B. glabrirostris, Herbst. This is a very variable species, both 

 as regards size, markings, and colour of legs ; it is easily separated from 

 all our indigenous species (except B. alismates) by its broad bilobed 

 third tarsal joint, and from the last-named it may be known by the 

 characters of the prosternum and funiculus, and by the absence of 

 distinct pubescence on the upper surface of the tarsi. The var. 

 nigrirostris, Thoms., may possibly be a distinct species ; it has the tarsi 

 and antennse piceous or black and the sculpture coarser ; there is also 

 a larger form which Mr. Newbery considers to be the B. lutosus of our 

 collections, and which may be called var. major {v. Champion, Ent.
