Dec. 1905.] Smith : New Species of Noctuid/E for 1905. 189 



brown shading which extends inward at the middle and thus completes a mottling of 

 the outer fourth of the wing. The fringes are solid deep brown. Secondaries soiled 

 whitish, smoky outwardly. Beneath : primaries smoky, paler along costa where the 

 inceptions of the lines of the upper surface are marked in blackish ; apex pale ; sec- 

 ondaries whitish, powdery along the costa, smoky at apex, with a narrow smoky 

 extra-median line and a small discal lunule. 



Expands : 1.20 inches = 30 mm. 



Habitat. — Cochise county, Arizona, June 24. 



One male in very good condition from Mr. George Franck. A 

 very beautiful species and a distinct acquisition to our fauna. It may 

 be that when a revision of this group is made that this species will not 

 be placed in the typical genus. 



Genus ACRONYCTA Ochsenheimer. 



Since the publication of the Revision of this genus by Dr. Dyar 

 and myself, considerable material has come to hand which has some- 

 what modified my opinion as to the standing of certain forms. Dr. 

 William Barnes also was good enough to send me a large series for 

 further comparison, which proves the distinctness of forms previously 

 considered identical. 



Acronycta obscura Hy. Edwards. 



I have referred this as a synonym of americana but believe now 

 that it is probably a good species. The material is scanty and, except 

 for the fact that the range of variation is not so great as I concluded 

 on a previous study, would not authorize changing the present status 

 of the name. I have only a single example myself and know of no 

 others except the types. 



Acronycta denvera, new variety. 



Closely allied to and probably a variety of dactylina. It differs in 

 the more even, less powdery and somewhat creamy-tinted primaries 

 which are really more nearly like those of hastulifera. The secon- 

 daries, however, are pale in both sexes and not much more powdered 

 in the male than in the female. All the specimens, 2 males and 4 

 females, are from Denver, Colorado, and dated July, where they have 

 any date at all. There is no difficulty whatever in separating the two 

 forms where they are comparable in sufficient numbers. 



Acronycta eldora, new species. 



Belongs to the americana group and is a close ally of the typical species. The 

 median lines are well defined, geminate, powdery, black rather than brown, the t. a.
