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 antenne, whereas in the latter genus 
there are seven; the genera, therefore, bear the same relation to one 
another that Ceuthorrhynchidius bears to Ceuthorrhynchus.

LIMOBIUS, 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 antennz; 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 sete. 
I. Elytra without a common dark band behind middle . . LL. pissimruis, Herbst. 
II. Elytra with a common dark velvety band behind middle, 
extending across the second and third interstices . . L. mrxtus, Boh. 
L. dissimilis, Herbst. (borealis, Payk). Rather short, black, closely 
covered with variegated brown and whitish scales, which usually have, 
in part at least, a slight metallic reflection ; eyes depressed; antenne 
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 patehes on some of the interstices ; pune- 
tured striz rather fine ; erect setz distinct ; legs red; the colour of the 
scales is somewhat variable. L. 25-3 mm. 
On Geranium pratense ; also at the roots of Geranium sanguineum ; 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. 
Z. 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 sete 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. 33-4 mm. 
Sandy places ; on species of Erodium, especially EZ. cicutarium ; very local, but 
sometimes not uncommon where it occurs ; Deal sandhills, locally common; Dover 
(Hall); Weymouth ; Exeter, very rare (Parfitt’s Catalogue),
