Mesoleptus nigricornis Provancher, 1886. Addit. Corr. Faune Ent. Canada Hym., p. 99. 9. 



sanguineum (Provancher). Que., N. Y., N. J., Alta. 



Tryphon sanguineus Provancher, 1875. Nat. Canad. 7: 118. i. k lectotype was selected by 

 Townes (1939); Barron's (1975) rejection of it is invalid because Provancher stated that 

 he had three males, and lack of agreement with the original description is not by itself 

 sufficient proof that the lectotype selected by Townes (1939) was not one of 

 Provancher's original syntypes.
