black puints and some while scales in posterior margin of each segment beyond 

 middle; similar below, with two pale ventral stripes. 



Primaries ochreous along inner margin, mixed brown and white with a few 

 ochreous scales toward costa. Costa itself narrowly blackish brown with white 

 dots. Dark triangle before cleft. Terminal area brown, hoary with white 

 scales, preceded by a faint transverse pale line, less complete on second lobe. 

 Spaces between this and triangle ochreous irrorate with white, with an elongate 

 triangular brown dash and costal shade on first lobe and two dashes on second. 

 Cleft margined with a few dark scales. Fringes white, grayish at angles, with 

 the usual basal dark brown scales along outer margin. Inner margin with 

 scattered brown scales and two poorly marked clusters. Secondaries brown, 

 third feather more ochreous. Fringes more grayish with white bases along 

 inner margins and at apices of first two lobes, containing a few brown scales 

 in basal half of third lobe. Expanse 20-26 mm. 



We have not examined the genitalia of a typical example. In 

 forms which may belong to this species they are similar to those of 

 Carolina, but with a broadly spatulate uncus. 



Distribution: Type locality N. Ore.; one paratype 9 is in the 

 Fernald collection. We have a single typical specimen from British 

 Columbia, taken by Mr. G. O. Day in June 



The types were reared from a species of Orthocarpiis. but we 

 have no knowledge of the early stages beyond this. . 



We doubtfully associate with this species a number of specimens 

 from Utah, Colo., Nev.. Mont, and Cal., taken May to July. Meyrick 

 returned some of these specimens as orthocarpi after comparing them 

 with the types in the British Museum, and though they are easy to 

 separate from the typical form, we find it hard to believe that they 

 are not very closely related to it. Together with fragilis, shastae and 

 albida they make up an extremely difificult group which we are inclined 

 to believe in a state of evolution. The named forms can he recog- 

 nized. Iiut whether to regard them as forms and races of one species 

 or as distinct species is a question which we are unable to decide. We 

 give here a general characterization of the group, and under eacli 

 name point out the features which we regard as distinctive of that 

 form. 



The head, body and appendages are as described under orthocarpi. 

 varying in shade from white to dark grayish and ochreous, and with 

 the legs variably marked. The markings of the abdomen are reduced 

 or absent.
