Pterochilus, King, 



Pterochilus cyaneipennis, Andrd. 



Pterochilus cyaneipennis, Ed. Andr6, Rev. Eut. Caen, vol. xiv. p. 355 



(1895). 

 Pterochilus korbi, Scliulz, Hymenopteren-Studieu, pp. 48-5iJ ('1905). 

 Pterochilus uterrinius, E. Saunders, Trans. Eut. fc>oc. Loud. p. 403 



(1905). 



In a note previously published (Ann. & Mag. Nat. Hist. 

 (8) vii. p. 99, 1911) P. aterrimus was synonymized with 

 P. horbi on a comparison between the types, which are in the 

 National Collection. There can be no doubt that they are 

 the Pterochilus cyaneipennis of Ed. Andre, with wiiose 

 description they entirely agree. The type locality of 

 P. cyaneipennis is also Biskra.
