PHYCIODES I., II. 



discoloration at the end of the cell ; the marginal cloud narrow and dark, con- 

 cealing the crescents ; at the angles the crescents are of the color of the ground ; 

 in sonip examples the middle crescent on the cloud is silvered ; in some also the 

 cloud is reduced to a mere shade along the margin. There is little variation in 

 the male, but much in the female. Some of these are like the male, the reticu- 

 lated lines stronger, and a slight costal patch present ; the cloud as in the male. 

 I designate this variety as A. (Figs. 1, 2.) Var. B has the lines heavy, the 

 costal patch conspicuous and dark, and a similar but larger one on middle of 

 disk ; the cloud diiFuse. (Fig. 3.) This resembles Var. D, J[fama. 



Many examples of the summer brood of Morpheus are very melanic on upper 

 side, especially those from the Catskill Mountains ; the black being intense, while 

 the discal band on primaries is pale yellow. (Fig. 4.) 



A third variety, C, I have received from both Georgia and Texas, taken in May 

 and August. On the upper side the fulvous is bright ; the lines are fine and the 

 meshes open ; on the under side, secondaries are without patch or cloud, any 

 dark shade being limited to the middle crescents on the edge of the margin ; 

 the submai'ginal lines on both wings dark and heavy, and the reticulations either 

 faint or obsolete. (Fig. 5.) I have not observed this variety in more northern 

 examples. 



Egg. — Conoidal, ti-uncated, depressed at summit, rounded at base, the lower 

 half indented like a thimble, the excavations being shallow aiid arranged in close 

 and regular rows; the upper half .smooth, with about fifteen slightly raised ver- 

 tical ribs, terminating at the rim above ; color pale green. (Figs, a, c^, magni- 

 fied.) Duration of this st^age four to seven days. 



Young Laeya. — Length .06 inch ; cylindrical, largest anteriorly, the seg- 

 ments each well-rounded ; sparsely jiilose, the hairs black, and on the anterior 

 segments directed forward ; color yellow-green clouded with brown ; head obo- 

 vate, deeply cleft; pilose ; color dark brown. (Fig. 6, magnified.) Duration of 

 this stage five to six days. 



After first moult: length .1 inch ; cylindrical, stoutest in the middle segments; 

 armed with seven rows of short, fleshy, brown spines, each thickly set with short, 

 concolored bristles ; there is also at the base of body a row of small spines, sim- 

 ilar to the others, one on each segment from the thii-d, and over the pro-legs two 

 on each ; on the second segment a dorsal collar, with minute spines ; body 

 striped longitudinally with light and dark brown and sordid white ; the dorsum 

 light brown edged with white, and on this brown area two interrupted white 

 streaks ; on the side a dark brown stripe on light ground, and in line Avith the 

 lower lateral spines a white ridge ; under side, feet and legs brown ; head sub- 

 cordate, the vertices rounded, and across each a gray band ; another gray band
