Type.— 1^0. 6359, U.S.N.M. 



Described from many specimens in perfect condition, bred and 

 mounted by Mr. Koel)ele. 



From Mr. Koebele's notes in the U. S. Department of Agriculture 

 it is learned that he found the larvic al)unclantly near San Francisco 

 and in Berkeley County, California, in June on Baccharis j)/lula7'i.s. 

 The larva makes a gall on the steni, and, according to Koebele, "they 

 leave the galls when mature in the latter part of July and pupate in a 

 case of silk in the sand." 



It is not indicated in the notes whether this was under natural con- 

 ditions or in his breeding cage. The moths issued September 15 to 26.

Adjoining the basal fawn-colored part is a costal semicircular region, 

 heavily overlaid with dark fuscous, and outside this is another similar \ 

 dark costal spot, not so well defined. In the first of these dark semi- 

 circles on the middle of the cell is a dark reddish brown dot surrounded 

 with a few fawn-colored scales, and below the second costal semicircle 

 at the end of the cell is another similarly edged spot. A few dark 

 fuscous scales are sprinkled irregularly over the apical part of wing 

 and the extreme apex is dark fuscous. Hindwing silvery fuscous,
