282 PHYTOPHAGA. [ Lema. 
L. lichenis, Voet. (cyanella, Suffr., nec L.). Smaller than the 
preceding species, and with the elytra narrower in proportion and much 
more coarsely punctured; the shoulders also are less marked; as a rule 
the colour is less deep blue and somewhat greenish, but in this point 
both the species are variable; the thorax is constricted just before 
base, the constriction being striate at the sides; the upper surface is 
sparingly punctured behind the anterior angles, and has two parallel 
rows of punctures in the middle; the elytra are punctured in very 
coarse rows, the insterstices being furnished with very small punctures; 
the upper surface is occasionally violaceous or black. LL. 3-4 mm. 
By sweeping herbage in damp places; on willows, &c.; often found at roots of 
grass and in moss; generally distributed and common throughout the kingdom. 
L. Erichsoni, Suffr. Elongate, with the elytra much longer in 
proportion to thorax than in the preceding species, which it resembles 
in colour, and with which it has been compared by many authors ; it is, 
however, far more closely allied to LZ. melanopa, of which it might 
almost be regarded as a concolorous form; the thorax is scarcely con- 
stricted at base, and its disc is exceedingly finely punctate, with three 
irregular longitudinal rows of larger punctures on each side; the elytra 
are more finely punctured than in L. cyanella, and have the interstices 
transversely wrinkled. L. 4-44 mm. 
Very rare ; Ireland, near Waterford (Power), 1857 ; one specimen also exists in 
Mr. Stephens’ collection, where it is set apart as separate, but not labelled. Mr. 
Crotch (Ent. Ann. 1867, 124) is of opinion that our British specimens must be 
referred to an unnamed concolorous variety of L. melanopa, and that we do not 
possess the true LZ. Hrichsoni, Suffr. 
ZL. melanopa, L. Elongate, of a greenish-blue or cyaneous colour, 
with the thorax and legs red, and the antenne, apex of tibie, and 
tarsi black; eyes prominent ; thorax convex, with two or three rows 
of punctures on each side, slightly constricted before base ; elytra long, 
with rather strong punctured strie; legs rather long. L. 4-45 mm. 
By sweeping herbage; generally distributed and common throughout England and 
Wales ; Scotland, common in the south ; Ireland, near Dublin, &., and probably 
widely distributed. 
CRIOCERIS, Geoffroy. 
This genus contains about a hundred species, which are distributed 
over the greater part of the world, but are found more abundantly in 
tropical than in temperate climates ; twelve species are found in Europe; 
they are somewhat variable in form, but have the thorax much narrower 
than the elytra, which are oblong or elongate and subparallel or slightly 
rounded at sides; the eyes are emarginate; the head behind the eyes is 
constricted into a more or less distinct neck ; the legs are moderately 
long, and the tarsal claws are simple and not connate. 
The larva of C. merdigera is described and figured by Westwood (quoting from 
Reaumur) in the Modern Classification of Insects, i. p. 372-4, fig. 45, 12 and 13 ;
