30 INTRODUCTORY REMARKS. 



abdomen, with an aculeus scarcely exerted (^); 

 the next, those that have a falcated abdomen and 

 very short aculeus (f); the third, such as are 

 distinguished by filiform antennae with not more 

 than fourteen joints (i^). Evania is taken from 

 Sphex(l)y as is the case likewise with Chalcis(m'), 

 Pompilus(n), Scolia{o), and Philanthus (p)i 

 Bemhex consists oi Apes and J^^esp^e^q) ; Melli- 

 nus and Crabro of Spheces and Vespce(r') ; Hy- 

 lisus, Andrena, Eucei'a, and Nomada, are sepa- 

 rated from Apis(s) ; and Dorylus contains merely 

 Mutilla Helvola. The parts from which he takes 

 the Artificial Characters of his genera, are the 

 palpi, labium, jnaxillcc, lingua, and antenme. 



Fabricius seems to have made no attempt to 

 improve upon the Linnean subdivisions of the 

 genera^ but to have adopted them as he found 

 them. Apis only excepted, in which he drops 

 them. In his Entomologia Systematica and its 

 supplement, he has described 1207 species belong- 

 ing to this class.
