Psithyrus kodiakensis Ashmead, 1902a, p. 130. d". Kodiak, Ala^a; 

 VII. This synonymy is according to Franklin, who formerly (in litt.) con- 

 sidered kodiakensis to be putnami {B. kirbyellus). The latter determination 

 would seem more probable, as kincaidii i.s not supposed to occur on the main- 

 land. Ashmead .says the pleura of his species is covered with ochreous hair, 

 not dark as it should be in kincaidii.
