LEMONIAS I. 



side in line with uj^per 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./^,/^, /^.) ; color black, or black-brown ; the lower two- 

 thirds 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 

 to maturity (Figs./, /■".). 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, .]5, across 

 mesonotuni, .14 inch ; cylindrical, the abdomen long, ovoid, pointed at the ex- 

 tremity, not turned under, next thorax compressed ; head-case square at top, 

 sloping flatly at the sides ; the mesonotuni rounded, very littlti elevated ; whole 

 surface, except the wing-cases, thickly and equally beset with short whitish hairs ; 

 color 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 line of same color on side ; the crescent over eye orange. The chrysalis is 

 held by a girdle about the middle. (Figs, h, Ir.) 



Nais is 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 

 in South Colorado in 18S0, especially at Oak Creek Canon, where it was common. 

 He wrote that it first appeared there about the middle of July, but was most 

 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- 

 ings, flying from 10 A. m. to 2 p. m., and invariably settled near moist places. Its 

 flight was of a rapid, zigzag character, much resembling MeVdcea. 



Mr. H. K. Morrison found the species abundant in Graham Mountains, Arizona, 

 in 1882, and says: " I found Nais at an elevation of from 8,000 to 10,000 feet, 

 on the flowers of • White Sage,' Eurotia lanata. It usually holds its wings flat 

 while at rest, but moves them more than does L. Pahner'd." 



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 Neds. 

 One was still perfect ; the rest had each a hole in the top, exactly at the micro- 

 pyle, from which the larva had escaped. In the cotton which accompanied the 

 eggs, were four young larva3, less than one day old. The eggs had been laid on 

 twigs and leaves of Mesquit, Prosopis juliflora, by females confined in bag. I 

 gathered various sorts of leaf to tempt the little creatures to eat, among them
