1828 BUTTERFLIES BEYOND NEW ENGLAND. 



Caterpillar. Last stage. Head testaceous yellow red. Body greeu, slightly pubes- 

 cent; a slight dorsal stripe and nine oblique lateral bauds of dull green, and a mar- 

 ginal stripe of greenish yellow at the substigmatal fold ; thoracic legs of the color of 

 the head. Length, 24 mm. (Boisduval and LeConte). 



Chrysalis. Reddish, pointed with brown. Length, 18 mm. ; height, 7 mm. (Boisdu- 

 val and LeConte). 



This fine buttei-fly, called the Great purple hair-streak by Abbot, is 

 found in the southern half of the United States from ocean to ocean, and 

 extends also into Mexico as far as Yucatan and perhaps into Costa Eica. 

 Its northern boundaries are by no means well known, but though it has 

 been found in Nevada according to Edwards (presumably southern Neva- 

 da), it does not appear to range so far north as Eupsyche m-album, the 

 northernmost locality east of the Rocky Mountains being Illinois. 



The caterpillar is said by Abbot to feed on Quercus phellos and Q. cin- 

 erea. Its seasons are very probably the same as those of Eupsyche 

 m-album, as it is found flying at the time of peach blossoms in Florida 

 and was raised by Abbot early in September from a chrysalis whose period 

 vf&s seventeen days.

Imago. Head in front white with a pair of vertical black stripes just withiu the 

 lateral white edging, above covered with white, bluish white and black hairs. Palpi 

 silvery white, the upper surface black brown, the fringe composed of black hairs with- 

 out, white hairs witliin. Antennae with the stalk almost equally annulate with black 

 and white, but the black ratlier in excess, the club black brown, white along the lower 

 outer edge. Thorax covered above with blue white hairs, below a little paler; the 

 legs sordid white, the tibiae annulate above witli black. 



Wings above pale, glistening pruinose blue, with faint greenish reflections, the male 

 having the costal margin very narrowly, the outer margin narrowly, edged with black 

 brown; the female almost wholly dark brown, blackish brown next the extreme edge 

 and powdered heavily with blue scales, which almost entirely conceal the brown next 

 the base but on the outer half of the wing are much more scattered and reach, on the 

 fore wing, only the middle of the outer half of the wing; on the hind wing, however, 

 the outer border, at least toward the anal angle. 



Beneath, uniform, clear, dark slate brown, occasionally with a pallid ray following 

 the interspaces in the outer half of the wing ; in both wings there is a circular black
