 subcostal and median vein. A broad dark band crosses the outer third 

 of the wing, being broadest in the middle of the wing, where it is as 

 wide as the wing itself on the basal third ; its edges are very irregular; 

 it encloses an inner and a much larger outer discal black dot. Edge 

 of the wing with a marginal row of indistinct spots. Hind wings pale 

 gray. Beneath pale gray, forewings a little darker than hind wings, 

 the bands and spots obsolete.

Habitat. — California (H. Edwards). 



Differs from the Eastern C. albata (see p. 51) in the broad shade 

 crossing the forewings, while the general hue is duller, almost gray 

 white ; and the hind wings are grayish, while those oi albata are white. 

 Packard (loc. cit. ) 



The type of this species, taken near San Francisco, remains unfor- 

 tunately as a mutilated specimen, having been broken in its travels. 

 It is probably not rare, bat has been overlooked on account of its small 

 size.
