DEBIS I. 



3'ellow ring, pale or bright ; on secondaries there is a duplex sixth ocellus next 

 inner angle, each part very small, elongated. 



Body above yellow-brown, beneath 3'ellow-white, the abdomen lightest ; legs 

 brown-yellow, the tibiae whitish; palpi white within, with long black hairs in 

 front ; eyes brown-black ; antennte blackish above, ringed with white, red-brown 

 below ; club black, the tip red-brown. (Figs. 1, 2.) 



Female. — Expands from 2 to 2.25 inches. 



Very much as the male ; the ocelli varying in same manner, perhaps, however, 

 never so small as in some males. (Figs. 3, 4.) 



Egg. — Semi-ovoid, a little higher than broad, the base slightly rounded and 

 arched at the middle ; surface smooth ; color greenish-white. (Fig. a.) Dura- 

 tion of this stage from four to six days. 



Young Larva. — Length .13 inch, cylindrical; tapering slightly on both dor- 

 sum and sides from 2 to 13 ; ending in two short conical tails ; color at first yel- 

 low, somewhat tinted brown, after two days changing to yellow-green, more 

 green on dorsum ; on each segment from 3 to 12, above sjiiracles are six conical 

 tubercles forming as many longitudinal rows, three on either side, a dorsal, sub- 

 dorsal, and lateral ; on 3 and 4 they are 

 ^^^rl'^~t^^^u^^J^J^-'T^^^~4<:^ nearly in cross line, but from 5 to 12 are 

 ^ '&l^<;4i^^iJ!Ui'i^^i4i^^ ^" triangle, the dorsal one standing on the 



front ridge, the sub-dorsal on the rear, 



the lateral on the second ridge or a little

ilii^'l/ J^ li^^^lL>liJ^^4i!^^r each of these a long, slender, tapering 



hair, the end thickened (Fig. ¥) ; on 2 

 are three tubercles and hairs corresponding to the three rows, though not all in 

 line with them, and behind and between the upper two an additional one ; 

 against spiracle, to the front, is a fine hair, and just over it a shorter, coarser 

 one ; (see cut ; on the Plate, figs, b and ¥ fail to show the sub-dorsal tubercle 

 on 2 ;) on 13 are twelve tubercles, three on each side in the upper two rows, two 

 in the lateral row, two at the ends of the tails, and two short hairs in the con- 

 cavity between the tails; below the line of spiracles is a row of short, coarse 

 hairs, not thickened at ends, two to each segment, except on 3, 4, 13, which 

 have but one ; head at first nearly twice as broad as 2, at two days from the 

 egg one-fourth broader only ; ob-ovoid, truncated, slightly depressed at the 

 suture ; on each vertex is a small sub-conical protuberance, from the top of
