are present in the single specimen before the authors. The eyes are heavily 

 lashed behind, which with the narrower and longer wings shows a tendency 

 in the direction of those other forms placed by Smith in Scutogranima, but 

 now placed in Lasiestra and Lasionycta. 



Expanse: about 35 mm. (Slightly longer than S. submarina but appearing 

 much longer due to the narrower wings.) 



Genitalia: essentially of the same pattern and structure of S. densa but 

 differing from all species of the group in being much larger; so much larger 

 that no microscope is necessary to see that difference ; also there are differences 

 in the uncus, juxta, clavus and claspers. 



Type locality: "Colo." (Bruce). 

 Type : Holotj'pe $ , unique. 



SCOTOGRAMMA OREGON ICA Grt. 



1881, Grt., Can. Ent, XIII, 239, trifolii var., Mamestra. 



"Under this name I register Oregon specimens which appear to belong 

 to Trifolii, but differ by the concolorous fore wings, wanting the dark dashes 

 to the subterminal line which has no M-mark, or but a faint one. The hind 

 wings have a faintly yellowish tone. The claviform is reduced and rounded. 

 The dark reniform entirely contrasts. Otherwise I see no differences and 

 we have to do probably with a geographical variety. Kansas specimens are 

 somewhat intermediary. Five specimens of the variety are before me." 



The original description of orcgonica is quoted above. Consid- 

 erable confusion exists in regard to the use of the name. Apparently 

 Grote had two species or forms confused under this name, labeling 

 one specimen of each "Type". One of these types is now in the 

 British Museum, and is a female. The other is in the Neumoegen 

 Collection, and is a male. No definite fixation of type seems to have 

 been made, and as it appears the privilege of a subsequent worker to 

 select a lectotype from a mixed series, the male type in the Neumoegen 

 Collection is hereby designated the lectotype for the reason that females 

 in this group are most easily placed by matching to the corresponding 

 males. 



Morana Sm. is closely allied, with the markings slightly more 

 intensified on a paler ground. 



Obesula Sm. and ortruda Sm. fall into the same group of Scoto- 

 gramma, rather than into Polia. 



This arrangement of names leaves the species common in Alberta 

 nameless.
