Head light brown, whitish between antennae. Antennae whitish. Palpi 

 very short, oblique, whitish. Thorax and abdomen creamy white, the latter 

 with a brown dorsal line. Legs whitish, first two pairs infuscated within, the 

 tarsi ver>' slightly. 



Primaries creamy white with bright, but often faint, brown shade from 

 middle of costa of first lobe to near middle of anterior margin of cell. Base 

 sometimes with a few brown scales. Veins slightly brownish in paler parts of 

 wing. Fringes concolorous at their bases, darker at tips. Secondaries and their 

 fringes almost concolorous. Under surface of primaries slightly tinged with 

 dull brown, especially near base. E.xpanse 27-33 mm. 



Distribution: California. Types from Lake Co., June. We have 

 a small series from the San Bernardino Mts., July. 



The types are in the British Museum and our identification is 

 based on a specimen compared by Mr. Meyrick. Walsingham's de- 

 scription and figure are excellent, and the species need not be con- 

 fused with lactcodactylns, as has been done, nor with anstralis, which 

 was described as a variety. From the former it is separated by the 

 absence of marks from the primaries with the exception of the soft 

 brown shade, and from the latter by the relatively pale under surface 

 of these wings. The short palpi separate it at once from all related 

 species when comparison can be made. 



We know nothing of the early stages.
