ARGYNNIS IX. 



Female. — Expands from 1.8 to 2.1 inches. 



Upper side less bright than in the male ; the markings no heavier ; but ex- 

 amples occur which are darker fulvous, and others which are much obscured 

 over basal areas, and the fulvous is everywhere washed with brown ; on the 

 under side the base of primaries is more red than in the male ; in the darker 

 examples the disk and base of secondaries are more covered with brown or 

 brown-ferruginous ; and the spots of both wings are silvered, but not so per- 

 fectly as in many species. (Figs. 3, 4.) 



There is much variation, and one of the common varieties is represented by 

 Fig. 5. In this there is no trace of silver, and the spots are clear yellow-buff, 

 color of the ground of the wing. I have seen no female of this type. 



Egg. — Conoidal, truncated and depressed at top, rounded at bottom ; the 

 breadth to the height nearly as 8 to 9 ; marked by 18 thin, elevated, vertical ribs, 

 slightly sinuous or bent, one half of them running from base to summit, the 

 others but about two thirds the distance, then uniting with the first ; the ends 

 forming a serrated rim ; between the ribs the rounded depressions are crossed by 

 many very low horizontal ridges ; color yellow. (Fig. a.) 



Young Larva. — Length .06 inch, at 12 hours from egg ; cylindrical, of even 

 size from 2 to 10, each segment a little rounded ; color greenish-white (changing 

 in a few days to greenish-brown) ; marked by eight longitudinal rows of dark 

 tuberculous spots, three being above the spiracles on either side, and one below; 

 these spots are flat, oval or sub-triangular, and bear one or two small conical 

 tubercles, from each of which springs a long tapering hair ; under a high power 

 these hairs are seen to be barbed, and knobbed at the ends ; on dorsum of 2 is a 

 bar, corresponding to the four dorsal and sub-dorsal spots of other segments, and 

 on its front are six hairs, on the rear four shorter ones ; the spots of the dorsal 

 rows are sub-oval, each with two hairs ; of the sub-dorsal rows triangular and 

 smaller, each with but one hair ; of the third or mid-lateral row sub-oval, on 

 2, 3, 4 with two hairs, on following segments but one ; the spots of the fourth, or 

 infra-stigmatal, row are rounded, and except on 2 and 13, each of which has two, 

 have four divergent hairs ; along base, on 3 to 6, and on 11 to 13, is a line of 

 tubercles, one to each segment, with shoi't hair, but on 2 in same line is a spot 

 like those of upper rows, small, with two hairs ; the hairs of the dorsal rows on 

 the three anterior segments are bent forward, on the middle segments are nearly 

 upright, on the last four are turned back ; it is almost the same with the sub- 

 dorsal row, but in the raid-lateral the two hairs on 2, 3, 4 are turned in opposite 

 ways, and after 4 are bent down ; in the fourth row, the upper two on each spot
