MONOGRAPH OF THE NORTH AMERICAN PROCTOTRYPID^. 331 



de la Province de Quebec," page 154, a genus, Ropronia^ with one 

 species, pedkulaia., which he at first placed in the family Braconidcc, but 

 which subsequently in the same work, page 40G, he removes to the 

 Helorlnxe. The genus is unknown to me in nature, but from his de- 

 scription and figure of the anterior wing, I believe it to be a Braconid, 

 and it is in consequence not included here. 



HELORUS Latreille.

 (Type H. anomaVipen Panz.) 



This genus is sufficiently described in the characters given for dis- 

 tinguishing the group. It is parasitic in the cocoons of Chrysopa,, a 

 Neuropterus insect, and, so far, only a single species has been detected 

 in our fauna.

 ciety, and Coll. Ashmead. 



This species comes nearest to the European B. anomalipes Panz., 

 but it is slenderer, the scutellum smoother, the petiole rougher, and the 

 legs paler than in that species.
