large or small, rounded or angular or a streak, black or yellow in 

 the centre, or yellow with a darker ring around, even only with 

 the remnants of a ring. The discal spot of the secondaries is an 

 orange spot or ring, and is large or small, in five specimens 

 entirely wanting. The underside of the wings is similar to the 

 male ; the green of the secondaries is more grayish, rarely yellow- 

 ish green ; the discal spot is surrounded or not ; the pink basal 

 spot, when present, is very small. The expansion of wings varies 

 from 65 to 47 millim., the average size is 54 millim. The cut of 

 the wings differs as in the males. Some, which have to be men- 

 tioned later have the hind angle only 90° ; these wings appear to 

 be shorter and broader. The outer angle of the secondaries is 

 sometimes produced and angular. 



In C. Edwardsii, as in most species, occurs on the underside of 

 the wings in some specimens a series of faint submarginal brown- 

 ish spots and a larger dash on the costa. Seven specimens have 

 such a series more or less complete and faint ; sometimes very 

 few spots or only on one wing are present ; three have a second 

 spot above the discal spot. Six from Umatilla, Yakima, Klikitat, 

 have the brown dash near the outer angle more or less visible, but 

 the submarginal spots very faint, sometimes only one ; two of them 

 have a second spot above the discal spot. The females are alike 

 in varying. Of the six couples collected in copulation of one the 

 male is Philodice the female Edwardsii. Another pair show the 

 male without, the female with submarginal spots, and a third pair 

 in just the reverse. The brown dash is to be seen on three 

 females and in some others only indicated. 



All specimens were collected from June 24 to July 26, at 

 Umatilla, Or., and in Washington Territory, east of the Cascade 

 Mountains along the Yakima River. to 6000 ft. elevation, and in 

 July at Spokane 4900 ft. and higher in Colville Valley. In June 

 the specimens were freshly developed and probably belonged to 

 a second brood, as a few old and very worn males of a former 

 brood were still alive. In Colville Valley only the remnants of 

 the summer brood were observed. The species is very common 

 at Umatilla. 



Mr. H. Edwards (in Mr. Mead's Rep., Wheeler Surv., Vol. v, 

 p. 491) states, that near Virginia City, New, this species flies very
