Philanthiis, in Fabricius' original sense (1790) included 

 (1) Philanthiis Auctt. {nee Jrn.); (2) Cerceris Auctt. 

 (= Philanthiis Jrn.) ; and (3) Palarus Ltr. (= Gonius Jrn.) 

 — this will be discussed in the note next following {vide 

 p. 411). 



The composite genus Philanthiis F. was revised and 

 analysed in exactly the same way by Jurine and Latreille, 

 and both these authors retained the original name of the 

 genus for one of its divisions, but, unfortunately, not for 

 the same division, so that Philanthiis has three meanings : 

 Philanthiis Jrn. -|- Philanthus Ltr. + Palarus Ltr. (= Gonius 

 Jrn.) together make up Philanthus F. Jurine applied the 

 name to the group which contained the greater number of 

 Fabrician species — Latreille, to the group whose species 

 stood first in Fabricius' List. Philanthus, as thus limited 

 by Jurine, contains all the species with petiolate second 

 cubital cell ; of the rest, he calls one species Gonius and the 

 other Simblephilus. 



Latreille called the species with petiolate second cubital 

 cell Cerceris ; for Gonius he used Palarus, and for Simble- 

 philus he used Philanthus. 



Jurine's nomenclature being supposed to have first 

 appeared in 1807 (Nouv. Meth. Hym.) has been universally 

 held to be later than that of Latreille, and the latter has 

 consequently been adopted. The facts however are as 

 follows : — Jurine in the Erlangen List (1801) pubUshed 

 Simblephilus with a single exponent Philanthus pictus Pzr. 

 (i. e. triangulum F.) — Simblephilus Jrn., therefore, is the 

 Philanthus of recent authors. Gonius shall be treated 

 under the next heading. 



Philanthus of the Erlangen List is pubHshed in connection 

 with three names : Philanthus laelus and arenarius, and 

 Crabro labiatus Fab. — the last of these is not an original 

 type of Philanthus F., and may be disregarded nomen- 

 clatorially — it is however congeneric with the others.
