282 PHYTOPHAGA. [Lewd. 



It. lichenls, Yoet. (ci/anel/a, Suffr., nee 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 iusterstices being furnished with very small punctures; 

 the upper surface is occasionally violaceous or black. L. 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. 



Zi. Urichsoni, 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 L. 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. 4-4| 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 L. Erichsoni, Suffr. 



Zi. melanopa, L. Elongate, of a greenish-blue or cyaneous colour, 

 with the thorax and legs red, and the antennae, apex of tibiae, 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 striae ; legs rather long. L. 4-4| mm. 



By sweeping herbage ; generally distributed and common throughout England and 

 Wales ; Scotland, common in the south ; Ireland, near Dublin, &c., 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,!, p. 372- 1, fig. 45, 12 and 13 ;
