commori in my experience and has been in our lists as an Orthosia. 

 It must in future be Helioihis chloi'opha Hbn., with lupatns Grt., as a 

 synonym. 



Lygranthcecia tiiberculum Hbn. = dorsilutea Wlk. There seems 

 to be little doubt of the correctness of this reference ; but I am not at 

 all sure that there are not two closely allied species involved. Both 

 names are based on eastern specimens and I have an example from 

 Texas that belongs to the same series. Some Colorado examples, how- 

 ever, seem to suggest another species and more material is needed 

 before we can be sure on this point. 



Lygranthcecia constricta Hy. Edw. The position of this species 

 I have discussed in this Journal, XIV, 24. It must, in future, be 

 listed as an aberration of marginata. 



Porosagroiis patula Wlk. = septentrionalis Moeschl. This is as I 

 have made it out; but I made both names to = fusca Bdv., and 

 that proves to be an error. The suggestion that his species was 

 identical v^\\\i fusca was Moeschler's originally, in 1870, and I saw no 

 reason to doubt it. The reference of patula to septentrionalis was 

 made by me. Hampson now vazk&s fusca Bdv., the same as Euxoa 

 cinerea Schiff"., a species which is not autoptically known to me. 



Euxoa incubita Sm., is ^ septentrionalis Wlk., as stated by Hamp- 

 son. As I pointed out in 1904 the species allied to messoria had 

 not been distinguished in 1893, and when I differentiated them in 

 1900 I did not have duplicates of the form actually described by 

 Walker. 



Euxoa insulsa'SNlk.: this species I identified with i]\G ca?fipestris- 

 decolor series in 1893, and cited along series of synonyms. Hamp- 

 son referred the species to messoria in his catalogue and I took the 

 liberty of doubting the reference. Reexamination of the type proves 

 that my original reference was correct and that insulsa has nothing to 

 do with messoria. The specimen is obscurely marked and to one not 

 familiar with the wide range of variation found in this particular 

 species the error was a natural one. There is perhaps no more wide- 

 spread, common and variable form than this and of the series of 35 

 which I have in my cabinet, no two are quite alike. In a series of 

 probably 100 duplicates I have every type from almost immaculate to 

 brilliantly contrasting well written examples. The black filling in the 

 cell in this species is a variable quantity and less constant than in any 

 other species of the series.
