family, notwithstanding its simple penultimate tarsal joint * (^Jlg. 32. 

 15.) : one of its mandibles is represented at Jiy. 32. 14. De Geer 

 has given an account of the larva of the Pytho depressus (an in- 

 habitant of Europe), and which he found under the bark of fir 

 and pines in Sweden. (^Memoires, yo\.s. pi. 2. f 15 — 20). I am 

 indebted for specimens of this larva {Jig. 32. 16.) to Mr. Shuckard, 

 and which were collected in Sweden, by F. Walker, Esq., in 1836. This 

 larva bears considerable resemblance to that of Pyrochroa, being quite 

 flat and parallel, with the head semicircular, and narrower than the 

 prothorax ; the 11th and 12th segments of equal size, and the 13th 

 nearly as large^ and terminated by two lateral curved denticulated 

 spines (^fig. 32.17.), beneath which is placed an anal proleg. Bouche 

 has also figured the larva and pupa of this insect, with details [Natiirg. 

 der Lis. Tab. ix. f. 13—22.). 



The only British genus is Pyrochroa, comprising two British species 

 of moderate size, distinguished by their pure red colours. The beau- 

 tiful exotic genus, Dendroldes Lair., is distinguished by the elegant 

 plumose antennte of the males. I am indebted to Mr. R. H. Lewis 

 for a fine species of this interesting genus, which is extremely rare in 

 North America, where he found it in May, 1834', beneath the bark of 

 the maple trees, of which the corduroy or crossways of the Great 

 Huron road are formed, in company with Brentus maxillosus. 



The third family, LAGRiiDiEf , corresponding with the tribe Lagria- 

 rise of Latreille, is characterised by having the head and thorax con- 

 siderably narrower than the elytra, which are soft and flexible, 

 (^fig. 32. 18. Lagria hirta, $ .). The thorax is subcylindric or ovoid and 



• Mr. Kirby has introduced this interesting genus into the family Cucujida?, 

 asserting its affinity to my genus Catogenus. I cannot, however, adopt this re- 

 lation as of so high a value as that which is manifested towards tlie Pyrochroida;.
