 Perilissus araius Burks, 1952. Ent. Soc. Amer., Ann. 45: 101. 6, 9. 

 bicolor (Cresson). Que. s. to S. C, w. to Mich, and Ala. 



Mesoleptus bicolor Cresson, 1864. Ent. Soc. Phila., Proc. 3: 269. S. Erroneously suppressed 

 as a synonym of Prionopoda ruficoniis Ashmead in the revision of Burks (1952); P. 

 bicolor (Cresson) is not preocc. in Perilissus by P. bicolor Brischke, 1878. 

 Prionopoda ruficornis Ashmead, 1896. Amer. Ent. Soc, Trans. 23: 198. 6.

 concolor (Cresson). N. B. s. to Va., w. to Mich., Iowa, and Colo. Host: Dolerus sp. Townes 



(1970) placed concolor as a subspecies of P.filicornis (Gravenhorst); I have compared 

 specim.ens of concolor and P.filicomis decoloratus (which see) and believe that concolor 

 is specifically distinct.

Mesoleptus unicolor Cresson, 1864. Ent. Soc. Phila., Proc 3: 271. [female]. 



Mesoleptus discolor Cresson, 1864. Ent. Soc Phila., Proc 3: 271. S. In his revision, Burks 

 (1952) incorrectly suppressed discolor as a synonym of unicolor, apparently having 

 regarded page priority as grounds for disregarding Townes' (1945) first revisor decision. 

 Townes (1970) placed discolor as a subspecies of P.filicomis (Gravenhorst), but Townes 

 (1976, personal commun.) has confirmed my supposition that this was an error; it had 

 been his intention to place Mesoleptus decoloratus Cresson (which see) as a subspecies 

 of P. filicornis.
