Discussion.—As discussed under the following species, the fore- wings of 37 female specimens of A. barberella were measiued and compared to those of A. pallida. The great majority (29) of these 37 specimens were reared from the flower stalks of Agave palmeri, collected near Ray, Arizona; the remaining 8 females were collected at lights in Madera Canyon, Santa Cruz Co., Ariz.

Discussion.—As discussed under the following species, the fore- wings of 37 female specimens of A. barberella were measiued and compared to those of A. pallida. The great majority (29) of these 37 specimens were reared from the flower stalks of Agave palmeri, collected near Ray, Arizona; the remaining 8 females were collected at lights in Madera Canyon, Santa Cruz Co., Ariz. The latter moths ranged somewhat larger in size ( mm) than did the reared specimens ( mm), but were very similar in regard to all other characters examined. The mean difference in wing length between the two populations was found to be significant (F=*) although not highly so. Because this degree of difference may be due, in part, to an in- adequate sample, especially from Madera Canyon, and since these two populations are essentially identical in aU other respects (including valve-genitalia ratio), only one species has been recognized in the material examined.
