bide m line with upper lateral row, and both black and white hairs at the end 
the latter long, horizontal (Fig. g.)- the white hairs from the several segments 
form a fringe completely around the larva; head obovoid, the sides well rounded 
the top depressed the vertices rounded, and covered by the protuberances of 
second segments (Figs./ 3 ,/ 4 ,/ 5 .) ; color black, or black-brown; the lower two- 
tlmds thickly covered by a yellow down, with a few long, depressed white hairs. 
There was no variation perceptible in the shape of the head from second moult 
ila uri y ( igs./,/.). From fourth moult to pupation, sixteen days. (The 
whole body, in the last two larval stages, was covered with minute hairs, which 
cannot be represented on the Plate, and at the base of each hair was a white 
point, giving a mottled appearance under the glass.) 
Chrysalis. — Length, .45 inch ; greatest breadth across abdomen, .15, across 
mesonotum .14 inch; cylindrical, the abdomen long, ovoid, pointed at the ex- 
tremity, not turned under, next thorax compressed ; head-case square at top, 
s oping flatly at the sides; the mesonotum rounded, very little elevated ; whole 
surface, except the wing-cases, thickly and equally beset with short whitish hairs • 
co or of anterior parts and wing-cases gray-brown ; the general color of abdomen 
greenish, rather dark; a dorsal line and two sub-dorsal bands gray-brown, and 
one me of same color on side ; the crescent over eye orange. The chrysalis is 
held by t a girdle about the middle. (Figs, h, h 2 \) ^ 
Nais ms found in Arizona, New Mexico, and has been taken at least as far to 
the north in Colorado as Denver and Boulder. Mr. B. Neumoegen observed it 
m South Colorado in 1880, especially at Oak Creek Canon, where it was common.

abundant toward the end of the month and beginning of August, but had en¬ 
tirely disappeared by the middle of August. It was always found on open clear¬

On July 20, 1881, I received from Mr. Doll, the agent employed by Mr. Neu¬ 
moegen in making collections of Lepidoptera in Arizona, several eggs of Nais 
One was still perfect; the rest had each a hole in the top, exactly at the micro-’ 
p> c, fiom which the larva had escaped. In the cotton which accompanied the 
eggs, were four young larvae, less than one day old. The eggs had been laid on 
twigs and leaves of Mesqmt, Prosopis juliflora, by females confined in bag. I 
gathered various sorts of leaf to tempt the little creatures to eat, among them
