Ageniella perfecta (Provancher). 



Type male bearing yellow label "783" in the Derniere Pro- 

 vancher Collection, Public Museum, Quebec. 



The type runs to perfecta in Banks' table (Jn. N. Y. Ent. 

 Soc, vol. 19, 1912 (1911) p. 234) but differs from a specimen (in 

 Banks' collection) determined as that species in the shape of the 

 third cubital, which is larger and has the outer margin oblique 

 (not curved) and the second recurrent is a little beyond middle. 



Ageniella rufigastra (Provancher). 



Type female bearing blue label "122" (script) and yellow 

 label "1419" (printing) in Derniere Provancher Collection, 

 Public Museum, Quebec. 



This species has usually been considered a synonym of congrua 

 Cresson, but the type differs from a homotype of congrua made by 

 Banks (in coll. Banks) in the blackish hind legs and in the decidedly 

 postfurcal nervulus. 



Episyron griseus (Provancher). 



Provancher's type is a male, not female, and is in the Derniere 

 Provancher Collection in the Public Museum of Quebec, bearing 

 a yellow label "1011" on pin. 



This species is related to higuttatus etc., but may be dis- 

 tinguished by the angulate posterior margin of pronotum and 

 absence of markings on the abdomen. The abdominal markings 

 are, however, not constant, and specimens from Canada (Baker 

 collection) in the National Museum, which have the posterior 

 margin of the pronotum angulate but have two lateral spots on 

 the third tergite, have been placed under Provancher's species. 



f 

 Pompiloides apicatus (Provancher). 



Type female bearing yellow label "769" in Derniere Pro- 

 vancher Collection, Public Museum, Quebec. 



The following notes may aid in the determination of this 

 species. Propodeum shining with a distinct median furrow; 

 second and following tergites with appressed pile; nervellus post- 

 furcal; first intercubitus strongly curved; third intercubitus
