ARGYNNIS VI. 



hairs ; legs reddish buff; palpi buff, fulvous in front and at tip; antennae black, 

 fulvous beneath ; club black tipped with ferruginous. (Figs. 1, 2.) 



Female. — Expands about 3 inches. 



Upper side darker, more red, much more obscured at base ; the marginal lines 

 heavy and on primaries more or le.ss confluent ; on same wings the submarginal 

 spots are heavy and rest on the lines ; all the mai'kings and inscriptions heavy, 

 the mesial band connected ; on secondaries this band is either made of separated 

 spots, or the posterior half is connected, the rest separated. 



Under side of primai'ies fiery red, the apical area as on the hind wing, the 

 silver spots large ; the sixth spot more or less silvered, and sometimes the sev- 

 enth partly ; often there is a dash of silver on the basal side of the rounded 

 spots in the lower three interspaces, and narrow, lanceolate spots of silver are in 

 the lower subcostal and both discoidal interspaces between the marginal and 

 discal rows (this excess of silver is very unusual in the genus) ; secondaries, as 

 described for the male, of either olive or dark I'ed-brown, solid color ; the silver 

 spots as in male in number and shape, enlarged ; the costal and inner margins 

 more extensively silvered. (Figs. 3, 4.) 



Egg. — Conoidal, truncated, and depressed at top ; in general like A2ihrodite, 

 but taller than broad, and taller in proportion to the width at base, the sides less 

 convex (comparing some of the allied species, in Alcestis the breadth is to the 

 height as 80 to 96, in Aphrodite as 80 to 90, in Cybele as 80 to 80) ; marked by 

 eighteen prominent, vertical, slightly wavy ribs, about half of which extend from 

 base to summit, and form around the latter a serrated rim ; the remainder end 

 irregularly at three foiirths and upwards distance from base to summit, some- 

 times squarely at one of the cross ridges, but usually curve towards and unite 

 with the long ribs; the rounded interspaces separated by nearly equidistant 

 fine cross ridges; color when first laid greenish yellow (Fig. «). Duration of 

 this stage twenty-five to thirty days. 



Young Larva. — Length at twelve hours from the egg .08 inch ; cylindrical, 

 stoutest anteriorly, tapering backward, the dorsum sloping considerably ; color 

 brownish green, semitranslucent ; marked by eight longitudinal rows of dark, 

 sub-triangular, flat, tubei-culous spots, three of which are above the spiracles on 

 either side, and one below ; these bear small tubercles ; in the iipper, or dorsal, 

 row two, in the next two rows one, in the lowest row four, each giving out a 

 long, tapering, clubbed hair ; on front of 2 is a large blackish dorsal spot bearing 

 three tubercles on either side of the mid-dorsal line, and below it, in line with 

 the third row, is a small spot with two short hairs ; and near the front, against 

 the spiracle are two points, each with very short hair; on 3 and 4 the spots of
