The larva mines leaves of Ceanolhus divaricatus, forming a nar- 
row brownish contorted tract (Fig. 14), about 3 cm. in length, with 
a breadth of 1 mm. at the end and almost filled with frass. 
Cocoon red dishbrown. The type specimens were bred from 
mines received from Dutch Flat, California, in February; imagoes 
in March and April. 
The mines occur in great numbers on the same plant in southern 
California.

The larva is a miner in leaves of wild cherry (Prunus serotina), 
and occasionally on wild plum (Prunus americana). The mine 
(Fig. 15) is much contorted, especially at first, often by confluence 
forming a blotch, later distinct, with the frass scattered to near the 
the end, where it is collected into a broad line. The leaf of wild 
cherry is discolored and reddish around the mine. Cocoon 
ocherous, sometimes reddish.
