traordinary and unknown fact, and he studied it in all its details. They are very sin-

11 ' The author of the memoir describes and figures the larva of this Trachys, which 

 has a very peculiar form, as well as the pupa, which is transformed without being 

 enveloped in a cocoon. He compared this larva with those of other Buprestidae 

 already known, in order to indicate by figures the peculiarities which distinguish them. 

 He examined the interior of the vesicle of the epidermis, where he found the remains 

 of the former skin, those of the digested matter which had served for the growth of 

 the larva, and proof that, among other parasitic larvae, that of a Cynips for example [?], 

 had made their food of it, and took its place. 



"' We think that the memoir of M. Leprieur confirms and developes much better 

 the first observation of Reaumur upon the larvae of the Trachydes, all of which have 

 very probably the same manner of living ; that his researches establish a positive fact 

 upon a point too little known in the history of these insects, that the exactness of his 

 researches merits the approbation of the Academy, which has received them with 

 interest, and that the publication of them is very desirable.' "
