enough in the environs of Paris. Its larva is very long, and 

 very slender, almost similar to a wire. It so multiplied some

 sioned very great destruction.* 



The others have the palpi very short, and similar in the 

 two sexes. The antennae are always simple, and of the same 

 thickness throughout. The tarsi are short, and the penult 

 articulation is bilobate in some of them. 



The body is of a solid consistence, with the top of the head 

 imequal or furrowed, and the corslet almost square or subor- 

 bicular. 



•CuPES, Fab., 



In which the antennae are composed of articulations almost 

 cylindrical, and in which the penult of the tarsi is bifid. 



The mandibles are unindenticulated under the point. The 

 palpi, the jaws, and the tongue, are vmcovered. The tongue 

 is bilobate, and the chin is almost semi-orbicular. Two spe-

In which the antennae are grained, and all the articulations- 

 of the tarsi entire. 



The mandibles, as far as it appears to me, are narrowed 

 and almost tricuspidate at their extremity. The chin 

 is corneous, very large, buckler-formed, and termi-

 served as a type to his description, and which now forms a part of the 

 collection of M. le Comte de Jousselin, at Versailles, ought to form a 

 peculiar genus. See also the Lymexylon fiahellicorne of Panzer, Faun.
