* Latreille describes Platygaster as having the third joint of the antenne much 
longer than the following joints, citing P. ruficornis as the type. Having examined 
and made a drawing of Latreille’s typical specimen, attached to the generic label in 
his own hand-writing, still contained in the collection of the Baron Dejean, I am 
able to confirm this description (as stated in the Mag. Nat. Hist. vol. vi. p. 
421.). The species considered as such by Messrs. Haliday (Ent. Mag. vol. 1. p. 270.) 
and Walker (Ditto, vol. iii. p. 240.), must therefore, from its sectional characters, 
be distinct. The last paragraph in the note of the latter (Jbid. p. 243. a.) must 
consequently be struck out. 
+ Deceived by the filiform antennz of the females of some species of Platygaster, 
I regarded them as males; and considered as their females other species which have 
also the abdomen elongated posteriorly ; and upon which I constructed the genus 
Epimeces. Mr. Walker, in his Monograph, has pointed out this error ; considering 
these females as forming separate sections in the genus Platygaster. ‘The name 
Epimeces may, however, be retained for the species with filiform antenne in the 
females, which I had regarded as males.
