COLEOPTERA. — CLERIDil':. 265 



the extremity of the body was not hijured, or merely shrivelled up. 

 The body of the pupa is terminated by two points. Several small 

 beetles, with their larvje and pupte, were found in company with 

 this Clerus, upon which it probably subsisted (Annales Soc. Ent. 

 France, 1835, plate xvi. p. 581.) 



Mr. G.R.Waterhouse found several larvae in rotten whitethorn wood, 

 in Kensington Gardens, during the winter months, in company with those 

 of Anobium tesselatum, agreeing in structure, although some were of 

 a yellowish white colour, spotted with pink ; whilst others were entirely 

 pale pink above and pale yellow beneath. The former he considered 

 to be those of Thanasiraus formicarius, and the latter of Opilus mollis. 

 As these larvae (for one of which I am indebted to Mr. Waterhouse) 

 did not appear to bore into the wood, it seems probable that they fed 

 upon the larvae of the Anobium. Subsequently he has published a 

 description of the pink larv&e, which remained two years in the larva 

 state (although it appeared to be full-grown when captured), previous 

 to assuming the pupa state, from which, however, it soon emerged as 

 Opilus mollis, as he had surmised. This larva (^Jig.29. 12.) is about 

 half an inch long, of a soft consistence, and covered with long ru- 

 fescent hairs. The legs are short, and the extremity of the body termi- 

 nated by two corneous diverging protuberances. The mandibles are 

 short, stout, and unidentate (^Trans. Ent. Soc. Lond. No. 1. pi. 5. Jig. 1.) 

 These larvaj are also found in dry and rotten willows, beneath the 

 bark of which the perfect insects are also found. Latreille states that 

 they are also found in houses, feeding upon the larvae of other 

 insects. 



Mr. Dale has recorded {Mag. Nat. Hist. No. 19.) the capture of 

 the larva of Tillus ambulans in rotten oak, on the 8th of IMay, and 

 "which was bred on the 11th, " from which it would appear, that it 

 required only three days to undergo its change in the pupa state. I 

 think, however, that some error must have crept into this state- 

 ment. Latreille mentions a curious instance of tenacity, in a spe- 

 cimen of Tillus elongatus Lin7i. which had seized his finger with its 

 jaws, and which suffered its head to be pulled off rather than quit its 

 hold. The Thanasimus formicarius (so named from its resemblance 

 to an ant) is found upon rotten or newly felled trees, especially those 

 of fir, under the bark of which the larva, according to Linnaeus, 

 resides, devouring the larva? of the timber-boring Anobium. 



Dr. Ratzeburg has more recently published an account of the
