(liiskv l)itiHls, of iiciirly equal widfli, niiguliilcd on (he iiirdiaii space, and 

 scalloped oil till! edges, which are Idaek ; those of the second and tliird 

 bordered wilh white. The-second and third, with tlie l)aiid hetweeii. form a 

 central, <lusky hand, occupying tlie middle third of the wing, and containing 

 an indistinct, brown, discal dot; the outer edge of the band is less aiigulated 

 than in the two j)rcceding species, and consists of three large scallops, being 

 straight on the costal and subcostal region. A siibrnarginal row of brown 

 patches, margined tsxternally with white points; toward the apex are three 

 longitudinal black streaks, with an obli(jU(', lilack, apical streak, intcrru])ted 

 by the venules. A row of marginal black dots. Fringe brown, pale at base, 

 and checkered w itii dusky spots. Hind wings tawny, rather dusky on inner 

 two-thirds, with the usual marginal row of fine, black dots. Beneath, ochre- 

 oiis dusky on the inner two-thirds of wings ; the outer edge of the dusky area 

 indented on the independent vein, and going from the second median 

 obliquely inward. Two minute, l)lack patches on the costa; near the apex 

 an apical black spot. Fringe checkered with dusky spots. 



Length of body, S, 0.40; of fore wing. 9, 0.4/ ; expanse of wings, O.i'5 

 inch. 



California (Edwards) ; Mendocino City (A. Agassiz, Mus. Comp. Zotil). 



Two specimens from Mendocino City (received from Mr. Behrens) are 

 larger than usual, with the inner brown band more zigzag, and a distinct line 

 on the upper side of the hind wings. 



This diminutive species seems more nearly allied in its .style of markings 

 to P. ijranata than any other. We have nothing like it east of the Kocky 

 Mountains.
