PLEUROTROPIS QUERCICOLA Ashmead. 



Asecodes quercicola Ashmead, Bull. No. 3, Kansas State Agric. Coll., Appendix, 

 p. vin, 1888.

 ection contains only a type male. 



PLEUROTROPIS TARSALIS Ashmead. 



JSolcopelte tarsalis Ashmead, Trans. Amer. Ent. Soc, vol. 21, 1894, p. 341. 



PLEUROTROPIS ASHMEADT, new name. 



Asecodes albitarsis Ashmead, Can. Ent., vol. 20, 1888, p. 103. [Not (Entedon) 

 Pleurotropis albitarsis Ashmead.] 



As the type of this species is not available, the interpretation here 

 adopted is that of Doctor Howard in A Study of Insect Parasitism.^ 



Although no satisfactory means have been found for distinguishing 

 the females of tarsalis and asJimeadi, the males may be separated as 

 follows: Funicle apparently four-jointed, club one-jointed, tarsalis; 

 funicle apparently three-jointed, club two-jointed, asTimeadi.
