tend to become strigate liturata 



Bluish white, markings black, so that primaries 



appear marbled marmorata 



10. Primaries blotchy black and white, all the normal 



Xoctuid markings present; secondaries smoky yellowish noctivaga 



11. Maculation of primaries normal, median lines in 



usual relation to each other, black basal 



marks present; disc of thorax not uniformly blackish perdifa 



Disc of thorax blackish ; t. a. line of primaries 

 unusually remote from base, median lines 

 abnormally close together, no black basal marks othello 



Acronycta hastulifera S. & A. 



This is a large species, expanding up to two inches in the female, smooth, 

 evenly whitish graj' with a creamy tinge, all the maculation easily traceable but 

 not contrasting. There is no basal streak, but a neat little black dash crosses 

 the t. p. line opposite the anal angle. 



The species has a wide distribution, extending from the Atlantic to the 

 Pacific; but is by no means common. I have male and female from California 

 without specific data, and these do not differ from a bred pair from the Atlantic 

 Coast. The species was not known to Hampson in 1909, and is not generally 

 represented in collections. The larvae feeds on alder and has been described 

 and figured. 



Acronycta hesperida Smith 



This is even a larger species than hasiidifera, the female reaching two and 

 one-half inches in expanse. It is blue gray in color, very powdery, with all the 

 maculation powdery and diffuse, broken and not contrasting. There is no dagger 

 mark crossing the t. p. line opposite the anal angle, but there is a little black 

 marked angle in the line that indicates its usual position. 



This seems to be a Pacific Coast species, extending northward into British 

 Columbia and eastward to Manitoba. Exact Californian localities are not avail- 

 able, but the Sierra Nevada Mountains are indicated. 



The larvw of this species also is known and is said to feed on alder. 



Acronycta felina Grt. 



This is a moderate sized, rather narrow winged species, the female reaching 

 an extreme of nearly two inches. The ground color is white with a yellowish 

 tinge and the maculation is not well marked. There is a narrow, slightly sinuous 

 basal line, the t. a. line is indicated on the costa, and the t. p. line is continuous 

 across the wing, consisting of an almost continuous paler shading, followed by 

 a slightly darker one. Slender, inconspicuous black lines or daggers cross the
