286 PHYTOPHAOA. [ClythfO. 



third joint of the latter being bifid ; the claws are simple ; the genus 

 contains forty species, of which eight are found in Europe and the 

 remainder are widely distributed from Siberia to the Cape of Good 

 Hope ; only one or two appear to have been found as yet in the New 

 World ; there is one British species, and a second has sometimes been 

 included in our lists, but it can hardly be regarded as indigenous. The 

 larvae of a considerable number of the species of Clythra have been 

 described by different authors ; they inhabit hairy cases of a leathery- 

 like material, which they drag about with them; the head is protruded 

 from the narrow end ; when full fed the insect retires into its case and 

 changes to a curved pupa ; the larvae are rather thick and fleshy, and 

 are curved behind as in the Lamellicornia ; they much resemble those 

 of C)*yptocephalus, both in form and in the fact that they inhabit cases. 



C. quadripunctata, L. Oblong, convex, subcylindrical, shining, 

 black, with the elytra reddish-testaceous with two black spots on each, 

 one near shoulder, and a larger one behind middle ; head depressed, 

 rugose, antennas short, black, with the second and third joints entirely, 

 and the fourth and fifth partly, red ; thorax transverse, strongly 

 narrowed in front, with large margins which are thickly punctured, 

 disc finely punctured; scutellum large; elytra distinctly, but not strongly, 

 punctured, with traces of fine raised lines, sutural angles obtuse ; legs 

 stout. L. 7-11 mm. 



Male with the last ventral segment furnished in middle with a broad, 

 shining, obsolete impression ; female with the same segment furnished 

 with a deep subtriangular impression at apex. 



On oaks, birches and hazels, and by sweeping herbage ; the larva is sometimes found 

 in nests of Formica rufa ; local, but not uncommon in some districts; London 

 district, rather common in places, Lee, Peckham, Chatham, Sandhurst, Woking, 

 Eppiug Forest, Weybridge; Whitstable ; Hastings; Portsmouth district; South- 

 tunpton ; New Forest; Whitsand Bay, Plymouth; Fordlands, Devon; Swansea; 

 Llangollen ; Bumt Wood, Staffordshire ; Bewdley ; Trench Woods, Bromsgrove ; 

 Hopwas Wood, Tamworth ; Northumberland district, Newcastle, &c. ; Scotland, rare, 

 Tay, Dee, and Moray districts. 



(C. Iceviuscula, Ratz. This species appears to be very closely allied to 

 the preceding, from which it differs in having the disc of the thorax 

 hardly perceptibly punctured and its margins narrow, and the sutural 

 angles of the elytra rounded ; the black patches on the elytra are some- 

 what differently shaped, that near the shoulders being larger. L. 

 7-11 mm. 



Mr. Crotch introduced the species on the authority of two old specimens 

 without locality which he found mixed with C. quadripunctata ; the 

 species requires confirmation before it can be regarded as indigenous. 



CRYPTOCEPHALINA 



This tribe contains about forty genera, of which by far the most 

 important is Cryptocephalus, which is the only one that is represented 

 in the British fauna ; the only other genera found in Europe are Pacliy-
