along file basi; of fringe, which is dusky-brown. Beneath, bright-oclireous 

 on both wings; a broad dusky band, angulatcd in the middle of the wing, in 

 the I'cniale consisting of two l)rown lines; this band disappears toward the 

 inner edge. On hind wings, an outer, much-curved, brown line. Brown 

 discal dots present on both wings.

This species varies much in the central part of the wing, the band 

 enclosing the discal dot varying from lirown to white, and the angle of the 

 outer edge being acute or rounded. It differs from all the other species 

 known to me by the bright ochreous under side of both wings, and the dusky 

 band bent at nearly right angles. Two specimens from Mendocino City are 

 larger, with the inner brown l)antls more zigzag, and a distinct line on the 

 upper side of the secondaries.

2 S and o 9. — Fore wings inclined to be rather square at the apex, 

 much as in P. hersiliata. Head and palpi as in P. truncata, the latter long; 

 third joint long and acute. Body and wings pale ash-gray, rather whiter than 

 usual. Head and palpi with white and dark scales; palpi dark on the tips. 

 Fore wings with four waved and scalloped lines; base of wing dark, two 

 basal lines parallel, the inner one situated half-way between the insertion of 

 the wing and the second line; it sends out a broad, truncated, prominent 

 tooth in the discal space, thence goes straight to the costa; on the internal 

 vein, it is slightly pointed inward ; the second line has a large full curve out- 

 ward in the discal space, with two scallops in the submedian space; a broad 

 whitish band, of the; same width throughout, containing two slight, broken, 

 diffuse, dark lines; the third line forms the inner edge of a dark, broad, sub- 

 cent lal l)and ; the line is curved outward in the anterior half of the wing, 

 going straight to the costa from tlu; median vein; it is bent inward on. the 

 costa; opposite the distinct discal dot, it sends outward a white, sharp, long 

 point; on I he median vein, it is scalloped outward, and twice inwanl in the
