COLEOPTERA. CERAMBYCID7E. 367 



The same fact has also been noticed by M. Audouin {Ann. Soc. Ent. 

 France, toni. ii. Ixxvi.). I am indebted to Mr. E. Blyth for a larva 

 found by him eating the interior of deal shelves in his dwelling-house, 

 leaving only the external surface entire : it resembles in all respects 

 the larva of the musk beetle, except that the prothorax is rather 

 broader : it has also six exceedingly minute legs. I have little doubt 

 that it is the larva of a species of Callidium. 



Dr. Ratzeburg has figured the transformations of Callidium luriduni 

 in his Forst-Insecten, pi. xvii. 



The Rev. L. Guilding has detailed the natural history of a West 

 Indian species, Lamia amputator Fabr. : it is found in the Mimosa 

 groves, and is destructive to the trees, both in the larva and perfect 

 states ; the former excavating the branches with labyrinth-like pas- 

 sages, leaving, when full grown, the surface of the branch alone entire, 

 within which it forms a cocoon of chips, and becomes a pupa ; and 

 the imago gnaws off the branches, biting circularly round their axis, 

 thus stopping the course of the sap, and the branch falls upon the 

 first wind. It also bites holes in the bark with its jaws, and then 

 deposits its eggs, by means of its long retractile ovipositor, in the 

 puncture thus made. (^Trans. Linn. Soc, vol. xiii.) 



Professor Peck has also given (in the Massachusetts Agricult. 

 Repos. and Journ., republished in the Zool. Journ. No. 8.) the natural 

 history of Stenocorus putator, of which the larva, when full grown, 

 eats away the wood of the thin branches of the oak, in which it re- 

 sides, in a circular direction, leaving only the bark entire, and which 

 is broken off by the first wind, and falls to the ground with the larva. 

 Professor Peck considered that this proceeding had for its object the 

 obtaining of a sufficient degree of moisture for the developenicnt of 

 the pupa, by the small twigs being brought into contact with the 

 moist earth. 



M. Sober has published a detailed account, with figures, of the 

 various states of Parmena pilosa, the larva of which resides in the 

 stems of Euphorbia Characias. The larva is described as being apod, 

 and 12-jointed, exclusive of the head, which is small ; the anterior 

 segment of the body is largest, and transverse-ovate; the remainder 

 arc transverse ; the penultimate segment being broader than tlie 

 preceding ; the segments are provided with lateral lobes ; the terminal 

 segment has two impressions and two small brown tubercles at the tip. 

 The pupa is also terminated by two diverging spines. (Ann. Soc. E. 

 France.)
