228 EHYNCHOPHORA. [Hyperina. 



enemies, takes about twenty-four hours in construction, and the perfect 

 insect emerges a few days after it has been completed. 



The genus Limobius chiefly differs from Hypera in the fact of having 

 six joints to the funiculus of the antennae, whereas in the latter genus 

 there are seven ; the genera, therefore, bear the same relation, to one 

 another that Ceuthorrhynchidius bears to Ceuthorrhynchus. 



I. Funiculus of antennae with six joints LIMOBITTS, Schonh. 



II. Funiculus of antenna; with seven joints HYPERA, Germ. 



LIIMOBIUS, Schonherr. 



This genus contains three species which are all found in Europe; two 

 occur in Britain ; they may easily be distinguished from Hypera by 

 the number of joints in the funiculus of the antennae ; the first joint of 

 the funiculus also is rather larger in proportion to the second ; the 

 scrobes are produced as far as the eyes ; the body behind the thorax is 

 short and broad and the elytra are furnished with erect scattered setae. 



I. Elytra without a common dark b;ind behind middle . . L. DISSIMILIS, Herbst. 



II. Elytra with a common dark velvety band behind middle, 



extending across the second and third interstices . . L. MIXTUS, Boh. 



It. dissimilis, Herbst. (boreatis, Payk). Eather short, black, closely 

 covered with variegated brown and whitish scales, which usually have, 

 in part at least, a slight metallic reflection ; eyes depressed ; antennae 

 ferruginous, with club darker ; thorax transverse, with the sides 

 moderately strongly rounded, and with three more or less plain light 

 longitudinal lines ; elytra variegated, with the suture white behind, 

 and with chequered black patches on some of the interstices ; punc- 

 tured striae rather fine ; erect setae distinct ; legs red; the colour of the 

 scales is somewhat variable. L. 2|-3 mm. 



On Geranium pratense also at the roots of Geranium sanijuineum ; rare ; Chat- 

 ham (Champion), Guildford (Power), Sandwich sandhills (Gorham) ; Llandudno ; 

 Selby, Yorkshire (W. C. Hey) ; Northumberland and Durham district, not common, 

 Hartlepool, &c. ; Scotland, very rare, Forth district, " Queensferry sea-shore, among 

 Ononis arvensis, Dr. Greville," Murray's Cat. 



Zi. mixtus, Boh. Allied to the preceding in form and general ap- 

 pearance, but larger, and easily distinguished by having a velvety black, 

 almost crescent-shaped, common spot on the elytra behind middle, which 

 extends across the second and third interstices ; the thorax has two pale 

 longitudinal bands, one on each side; the scales and setae of the elytra 

 are rather coarse and the interstices are slightly raised, and besides the 

 black patch behind middle, there are two small black spots at base, one 

 on each side of the scutellum. L. 3^-4 mm. 



Sandy places ; on specits of TSrodium, especially E. cicutarium ; very local, but 

 Fometimes not uncommon where it occur? ; Deal sandhills, locally common ; Dover 

 (Hall); Weymouth; Exeter, very rare (Parfitt's Catalogue).
