Capitonius ashmeadii (Dalla Torre). 



Promachus rubriceps Ashmead — Proc. U. S. Nat. Mus.,Vol.II, 1888, 



p. 653 (nee Ratzeburg or Pro- 

 vancher). 



Cenocoelius ashmeadii Dalla Torre — Cat. Hym.,Vol. V, 1898, p. 72. 

 Both males and females of this species are in the collections, 



and can be readily differentiated by the foregoing table. The 



species is a primary parasite of Liopus alpha and fascicularis in 



Sumach. 



Capitonius provancheri, new name. 



Capitonius rubriceps Provancher— Addit. Faun. Ent. Hym. Canad. 



1886, p. 135 (nee Ratzeburg). 



This species is closely allied to ashmeadii, but from the speci- 

 mens available can be readily distinguished from that species by 

 the characters in the foregoing table. It, as well as ashmeadii, 

 varies in having the head rufous, rufo-piceous or black. Specimens
