orange patch limited on inner side by the discal spot and a stripe in line 

 with same, starting from hind margin and narrowing ; sometimes this 

 stripe is at first black and dense, but dissolves into separate scales as it 

 nears the discal spot, or it is throughout but a long cluster of scales, 

 becoming obsolete near the spot ; this last is a narrow, straight and black 

 bar, clear cut on inner side, but on outer side usually a little incised, 

 widening somewhat on sub-costal and not quite reaching the edge of the 

 margin ; apex and hind margin to the stripe narrowly bordered with 

 black, with inner edge serrated; sometimes on the margin this border is 

 broken into spots. Secondaries have small clusters of black scales at the 

 ends of the nervules, sometimes wanting ; fringes of primaries yellow, 

 very little orange tinted next the margin, a broad black space at end of 

 each nervule ; of secondaries yellow, slightly black at nervules. 



Under side pale lemon-yellow ; the apical area a little deeper tinted, 

 and pinkish next the patch, all sprinkled with fine spots of grayish-green ; 

 the patch restricted, less bright ; the discal spot bisected, the upper part 

 being quadrangular, the lower triangular; secondaries have the nervures 

 and branches yellow, just at base orange, or varying from yellow to 

 orange; the surface much covered with little patches of grayish-green, 

 disposed along the nervures, but extending well into the interspaces. 



Female. — Expands 1.4 inch. 



Deeper colored than the male ; the orange patch not more than half 

 the width in male, paler ; the border brown, deeply serrated and having 

 on inner side a series of connected yellow spots, serrated without, yellow ; 

 at the base of each of these, and partly lying on the orange ground a 

 cluster of brown scales ; discal spot as in male ; the under side differing 

 from the male only in the depth of yellow. 



Mr. Morrison brought examples of this species from Nevada, 1878, 

 and I have seen 12 or 14 of these. I have formerly received the same 

 from Lake Tahoe, and other neighboring localities. Mr. Mead took 

 about a score at Yo Semite, all which were examined by me. The size is 

 that of Reakirtii and Thoosa. The color unlike either, being lemon-yellow 

 in both sexes, whereas Reakirtii is sordid white in both and Thoosa white 

 in male. The orange patch is brighter and the limiting band is not con- 

 tinuous nor of uniform density as in both these species. On the under 

 side the color and shape and abundance of the spots on secondaries is 

 nearest T/ioosa. In Julia these are larger, and cover considerably more
