14 THE CANADIAN ENTOMOLOGIST 



nearer trifolii. Oregonica stands as a species, with morana 

 Smith as a variety, and I believe that to be correct. Incon- 

 cinna Sm. stands next, and is most certainly well placed. 



Folia Ochs. Following Hampson, this generic name is used for 

 Mamestra of previous lists. Hampson, however, has found 

 Miselia Ochs. to be a prior name. Distincta Hbn. is a diffi- 

 cult species to place in a list, as it seems to have no very close 

 ally, but it surely has no justifiable position between deter- 

 minata and Columbia. Also the relationship suggested by 

 seeing leucogramma between Columbia and mediiata is new to 

 me. I believe cohtmbia to' be a local form of meditata, and 

 have expected that determinata may prove to be the same 

 species. 



P. ingravis is very likely the same as quadrata, though they are 

 here separated by twenty-two species. 



P. lubens is referred to cristifera by Hampson, but now they are 

 correctly separated. Invalida, which stands as distinct, I be- 

 lieve to be cristifera. The two Vancouver Island specimens 

 of g/awco^wHamp., on which the description was based, looked 

 at first rather sharply distinct from the poor series of lubens 

 in the British Museum, but after seeing more material, I agree 

 with the authors in considering it only a variety. 



P. mystica Smith (1699) should most certainly come next to nim- 

 bosa ^1696). 



P. dodi (1716). The correct place for this seems between tacoma 

 (1709) and lilacina (1717); and liquida (1707), of which I 

 consider meodana (1708) merely a variation, belongs to the 

 same group. I should prefer to see atlantica (1710) between 

 subjuncta (1686) and nevada (1687), and indeed in Western 

 Canada it may sometimes be confused with the latter. A 

 Calgary male in the British Museum bearing Barnes' and 

 McDunnough's label ''nevada'' is a dark, richly coloured 

 atlantica. * 



P. detracta (1659) would closely associate with goodelli (1718) » 

 and acutermina (1719) is very doubtfully distinct from the 

 latter.
