229, a. M. morana Smith (Ent. News, XXI, 361, Oct. 1910). 

 — oregonica Grt., in part. The form I had listed as "var. oregonica 

 Grt." Smith subsequently described as morana, and the species 

 is certainly not a variety of trifolii. 



I am under the impression that Grote described a mixture of 

 two species as oregonica, and attached a type label to one of each. 

 In the British Museum is a female type oregonica and those other 

 specimens from Oregon which seem to me certainly distinct from 

 trifolii, though Hampson makes them "Ab. 2 greyer, fore wing 

 more thickly irrorated with pale brown." In the New York Museum 

 are five Colorado specimens which I took to be the same species. 

 This form, besides being more thickly irrorated and greyer, differs 

 from trifolii in having less of a W in st. line, and the terminal 

 space not darker than subterminal, or scarcely so. I saw the form 

 in Smith's collection, and it is probably the one he refers to as 

 oregonica in his paper above mentioned. Together we agre d that 

 it fitted Grote's description better than did morana. In the Brooklyn 

 Museum I found a male type from Mt. Hood, Oregon, which struck 

 me at once as the "var. oregonica" of my Calgary list. It is larger 

 than the British Museum type, and browner, with a deeper W, and 

 impressed me as distinct therefrom, especially as Mr. Doll showed 

 me a long ser es like it from the Yellowstone. I have a Yellowstone 

 female which I compared with it, though mine is distinctly ochreous 

 throughout. By the description this is evidently morana. I have 

 taken no more than one specimen at Calgary, but have one from 

 Laggan (July 17th) and it occurs at Kaslo and elsewhere in B. C. 

 I have no specimens quite like the British Museum type in my 

 collection, and am not positive that Grote's name really involves 

 two species, but if it does, then by the strict law of priority, as the 

 ma'e sex in such cases should hold the name, oregonica, male type 

 at Brooklyn, would have preference over morana. That law having 

 been voted down, it remains to be decided whether morana shall 

 stand.
