COLLECTION OF ARTICULATED ANIMALS. 



(n 1 5). The insects belonging to the genus meloe 

 of Linnaeus were formerly considered as a spe- 

 cific against madness; M. Latreille is of opinion 

 that they were the buprestis of the ancients. 

 Those of the genus pyj*ochroa, Geoff., live in the 

 forests, and are distinguished by their fine scarlet 

 colour. The chrysomela boleti, Lin. (n i), is to 

 be sought for in the fungi of trees, particularly 

 in that called the boletus. 



We come to a new division of the coleoptera, 

 those which have four joints to all their tarsi ; 

 they feed upon vegetables during all the pe- 

 riods of their lives. They are divided into seve- 

 ral families, the principal of which are, first, 

 those with long antennae : the larvae of this 

 family live in the inside of trees, which they 

 hollow in such a manner as to cause them to pe- 

 rish. The genera priamus, QeofL,cerambj-jc y Lin. , 

 callidium, Fabr., necydalis, Lin., saperda, Fabr., 

 stenocorus, Geoff., leptura, Lin., and sporutylis, 

 Fabr., belong to this family. The cerambfjc gi- 

 gas (n i) is one of the largest exotic insects 

 known. The males of some species, as the cervi- 

 cornis(n2,] and maxillaris (n os 7 and 12), are dis- 

 tinguished from their females by the strength of 

 their mandibles. There are but three species in 

 France : the scabricornis (n 20 \ ihefaber (n 26) , 

 and the coriarius (n 27). During the day they
