 white-tipped towards the ends of the segments. xA.ntenn8e dark 

 grav. Fore wings gray, microscopically speckled with whitish. 

 Scale tufts almost black, the scales composing them tipped with 

 white; a large tuft below fold at basal third, another below the

Thirteen specimens. Mills College, Alameda Co., Cal., and 

 Camp Baldy, San Bernarclino Co., Cal., bred from larvcc on "Cas- 

 cara" {Rhamnns purshiana DC), an ev^ergreen, and also on a 

 similar deciduous species of Rhamnns. 



The larva feeds within a large inflated gall-like chamber 

 formed from the two halves of the leaf, which are closely appressed 



above, just below the margins of 

 the leaf, and near each end. The 

 leaf bulges between the lateral 

 veins forming a series of pouches

cysuocceus .unHosus ' gate ' chamber. (Fig. 22). The 



larxa is pale gra^-ish brown, with head and prothoracic shield 

 shining pale brown. A small silken cocoon is spun, often just 

 outside the larval habitation, where the sides of the leaf diverge, 

 or between leaves on the bottom of the breeding jar.

Head and palpi bronzy; antennae dark brown. Thorax and 

 fore wings very lustrous, colour varying, according to the direction 

 _of light from greenish golden to a brilliant reddish bronze. The 

 latter colour predominates near the base and along the termen 

 and around the apex of the wung. At one-third a narrow pale 

 golden fascia, somewhat nearer base on the dorsum; at two-thirds 

 a triangular costal spot, and a little nearer the base on the dorsum 

 a similar dorsal spot, with its apex produced and pointing obliquely 

 toward the middle of the costa. Cilia dark gray. Hind wings 

 dark gray, purple toward the apex, with golden brown cilia.
