usually lU'xt iu si/c in tiie sulx-osto-moilian, and in tiiL- others subequal ; they arc 

 arrani^ed in a sinuous curve correspondin;^ exactly with their disposition inalope; outer 

 niar.iiin narnnvly edued -with blackish and foUoAved by an eipially slender thread of 

 pale brown, succeeded by a darker tint than usual: Triuiic similar to that of the 

 fore winys. 



Alxlonien above and on sides of tiie color of tiie upper surface of the wings; below 

 ash gray. Appendages: upper organ with the hookas in the pi'cceding species, but 

 ratlicr slenderer, especially toAvard the base, slightly longer and scarcely more arcu- 

 ate; lateral arms directed toward the middle of the hook, turned strongly inward, 

 about one-fourth the length of the hook, rather bluntly pointed at the tip. Clasps 

 about tliree and a half times longer than broad, ensiform, tapering pretty regularly 

 frcnn base to tip. the basal half curving a little upAvard, the apical half sti'aight, the 

 tip bluntly pointed; apart from the hairs Avith Avhich it is clotiied. the ui)per surface 

 api)ears to be unarmed. 



Secondary sexual peculiarities. The androconia taper Avith nearly perfect regu- 

 larity, but a little more perceptibly near the middle of the distal half, and Avhile of 

 the same basal Avidth as in C. alope, are proportionally shoi'ter, being about .25 mm. 

 long and .01 nun. broad at 1)ase. See also description of fore Aving. under genus. 



Egg (64:;)). ■• About eighteen vertical ridges. Avith rounded excavations betAveen, 

 spring from the loAver part of the side and run to the edge of the top ; this last is 

 rounded and coAered Avith shallow cells, irregularly hexagonal around the outside, and 

 in the middle long and narroAv, about an oval central cell." (EdAvards.) 



Caterpillar. First stage. Head light yelloAV brown, specked Avith broAvn and 

 sparsely pilose, sometimes Avith cloudy brown patches on upper part of face. Bodj' 

 carnation, Avith a dorsal crimson line, and three similar closely approximated lines on 

 each side of the body; appendages Avhite. Length, 2,5 mm. (after EdAvards). 



Second stage. Head light green, Avith AA'hite papillae in A'ertical roAvs, each Avith a 

 Avhite hair. Body pale green, with dark green longitudinal stripes occupying the position 

 of the crimson lines of preceding stage ; extremity of caudal horns red; papillae Avhite, 

 each supporting a blunt Avhite hair. Length, i mm. (after EdAvards). 



Third stage. Head nearly as before. Body Avith the Avhole surface one shade of 

 yellow green, except a dark dorsal stripe, and a yelloAV infrastigmatal ridge. Length. 

 7.5mm. (after EdAAards). 



Fourth stage. Head emerald green, cOAcred Avith conical Avhite papillae. Body 

 nearly as in preceding stage. Length, 11 mm. (after Edwards). 



Last stage. Head emerald green, the surface covered with slightly paler, conical pa- 

 pillae and pubescent. Body dull yelloAV green, the sides a shade darker than the dor- 

 sal area, with a dorsal dark gi-een stripe, and an Infrastigmatal yelloAv stripe or line, the 

 caudal horns reddish; surface of body covered Avith fine Avhite papillae, each bearing 

 a tine Avhite hair, rendering the surface pubescent. Length, 30 mm. ; ])readth, 4 mm. 

 (after EdAvards). 



Chrysalis (83:7,8). -Whole surface one shade of yelloAv green, covered Avith 

 minute Avhite granulations ; along the inner margins of the Aving cases a cream white 

 line, another along keel of mesonotum, and one across top of head case" (Edwai-ds). 

 Length, 15 mm. ; breadth. 5 mm. 



Distribution (18 : 4). This butterfly is a uorthern representative of C. 

 alope, meeting it on common ground somewhere between the annual iso-
