A large number of specimens collected in July, igih at Bal- 

 sam, N. C, shows that the varieties described under the names 

 alhogalleriella, nonstrigella and quadristrigella form part of a 

 series in which there is a gradual increase in the number of 

 fuscous markings and in the extent of the wing occupied by 

 fuscous scales, culminating in a fourth form in which the entire 

 wing up to the first pair of dark streaks is suffused with fus- 

 cous, except the extreme costa. 



In O. albogalleriella the entire wing is white, except for the 

 apical dot and costal and dorsal streaks ; some of my specimens 

 have the dorsal dark spot faintly indicated by a few pale fus- 

 cous scales. Apical markings are absent in O. nonstrigella, 

 according to Chambers' description; I have one specimen in 

 which one costal streak and a streak beyond the apical spot are 

 indicated by faint dark lines, thus approaching quadristrigella, 

 which appears to be the most abundant form. In the darker 

 specimens there is considerable variation in the amount of fus- 

 cous on the wing. In all of these specimens there is an addi- 

 tional dark dorsal streak, proximal to the dorsal streak refer- 

 red to in the description of quadristrigella, and corresponding to 

 the first costal streak in the variety quadristrigella. The suf- 

 fusion of the basal three-fourths of the wing with fuscous 

 varies ; in some specimens it is confined to the dorsal half of 

 the wing and is not deep enough to obscure the dark dorsal 

 spot ; in extreme forms the entire wing to the first pair of 

 black streaks, except a narrow streak along the costa, is an 

 almost uniform dark fuscous.

Chambers described the species from captured specimens 

 from Texas. A series of specimens bred on Cornus asperifolia 

 Michx. at Cincinnati, one of which Mr. Busck has kindly com- 

 pared with Chambers' type in the U. S. National Museum and 

 pronounced identical with it, agree very closely, but show a 

 few minor variations from the typical form, among them be- 

 ing the golden tinge of the face in some specimens, and the dark
