I've \vatched you now a full half hour. 

 Self poised upon tliat yellow flower; 

 And, little Butterfly ! indeed 

 I know not if you sleep or feed. 

 How motionless ! and then 

 "WTiat joy awaits you, when the breeze 

 Has found you out among the trees. 

 And calls vou forth again I

Imago (1 : 1, 4 ; 11 : 1). Head covered with long, erect, graj^-browii hairs, often paler 

 at their base tlian at their tip, behind the eye with silvery griseous scales. Palpi cov- 

 ered at tlie sides witli lioary gray or dark, slightly greenish brown scales, the latter 

 below, and usually prevailing ; fringed beneath Avith long, very dark, slightly olivaceous 

 brown hairs, witliiu hoary griseous ; above fringed with similar hairs which are paler 

 at tlieir base. Antennae very dark, slightly greenish brown, the joints aunulated at 

 tlie base with white, most broadly below, and the whole upper outer surface more or 

 less tinged witli lioary, increasingly so toward the tip, the club being mostly grayish 

 hoary excepting at the tip, where the three last joints, like the whole under surface of 

 the club, vary from dull luteous to yellowish fuscous. 



Thorax above covered with loug, rather pale mouse broAvn liairs sometimes slightly 

 tinged with olivaceous, especially on tlie anterior parts; beneath with shorter, dark, 

 sliglitly olivaceous, bi'own hairs. Fore legs covered witli similar liairs. In the other 

 legs the femora are covered with silvery gray scales and fringed beneath with mingled 

 dai'k gray and hoary hairs often tinged with olivaceous. Tibiae and tarsi dusky 

 silvery gray above, silvery white beneath and within. Spines black, spurs luteous, 

 growing reddish toward tip, coveredwith white scales at base; claws yellowish brown, 

 duskier at tip. 



Wings above dark, deep brown with a scarcely perceptible purplish tinge ((J), or of 

 a similar but paler, somewhat slaty or grayish brown (?). Outer border of fore 

 Avings almost straight in the middle half ; of hind wings with scarcely perceptible 

 crenulations. In the outer half of the/o?'e icing, in the place occupied in C. alope by the 

 broad yellow stripe, the wing is tinged or clouded, sometimes scarcely perceptibly, at 

 other times and especially in the $ considerably, but generally very slightly, and never 

 to nearly the deptli it reaches in alope, with yelloAvish or ochraceous. The limits of 

 the patch are never more than faintly defined and often tlie wing is sbnply a little 

 paler in this region, the yellowish tint confined to tlie encircling of the black spots, 

 Avhich occur as in alope in the loAvest subcostal and lower median interspaces ; they 

 almost invariably are pupilled, either minutely Avith a A\iiite or violaceous Avhite dot 

 ( (J ) , or varying from a minute dot to a conspicuous pupil Avith bluish or violaceous 

 Avhitc. enclosing a Avhite dot or spot (?) ; occasionally the loAver is blind in the ^ ;
