80 INTRODUCTORY REMARKS. 



Tarsi quinque articulis, primo longitudino 

 tibiae, compresso, ciliato, transversim 

 sulcato, 



The greater part of the additional circumstances 

 introduced into this character, belong only to 

 certain families, and are not common to the whole 

 genus ; and the last, viz. the transversely sulcated 

 first joint or planta of the tarsus, is peculiar to the 

 neuter of ^pis m^llifica. 



The other work which I mentioned, was pub- 

 lished at Paris about six years since by M. Latreille, 

 under the title of " Precis des caracteres gene- 

 riques des insectes, disposes dans un ordre naturel" 

 This is a work of considerable merit, in which the 

 author manifests no common degree of industry 

 and accuracy, aided by great abilities. Though a 

 professed admirer of Fabricius, he proves himself 

 to be 



Nullius addictus jurare in verba mngistri. 



and with great good sense rejects the Fabrician 

 nomenclature of the classes, retaining, for the most 

 part, that of Linneus. The Hymenopterous insects 

 constitute his fifth class, which he thus defines : 



HYMENOPTERES. Quatre ailes inegales, nues, 

 Hyinenoptera. veinees, inferieures plus 



petites. 



Bouche munie de mandi- 



bules. Une langue ou 



levre inferieure renfer-
