directly to the internal margin. The middle line is straight, and 

 joins the inner end of the third before it reaches the internal mar- 

 gin. About one-half the distance from the third transverse line to 

 the posterior margin is a jagged, pale, transverse line extending 

 across the wing. The posterior wings are pale gray, marked with 

 two transverse lines, the inner of which is straight and the outer 

 sinuous like that of the fore wing. Beyond this is an obscure sub- 

 terminal whitish band. Upon the middle of the wing, between these 

 lines, is a distinct black spot. The wing beyond the outer trans- 

 verse line is more irrorate with dusky, the fringe pale with black- 

 ened scales in the intervals between the veins. The first segment 

 of the abdomen is covered with long gray pile ; the remaining seg- 

 ments are fulvous brown, with a double row of black blotches along 

 the middle. 



Larva. — Length, when full grown, two inches. The general color 

 is a reddish drab, ornamented with numerous irregular longitudinal 

 stripes of a reddish hue, varied wdtli yellow and bordered with jagged 

 lines of black. Four of these bands are continuous upon the back, 

 but vary greatly in width. On the sides they are much interrupted, 

 the stripe below the spiracles being broken up inti3 irregular patches. 

 That immediately above the spiracles is regularly interrupted, dis- 

 appearing at the middle of each segment. On the last two segments 

 all the bands are much interrupted and very irregular. The dorsal 

 stripes are confluent a little behind the middle of each segment, 

 from the fourth to the eighth, with the exception of a central stripe 

 of the ground color, by which all the transverse bands are broken. 

 These confluent band-like areas of the longitudinal stripes are, at 

 first, yellow, but all change to russet with the last moult, except 

 the anterior one, which remains a bright lemon-yellow. The surface 

 is smooth with the exception of a transverse row of about five black 

 hairs to each segment, each arising from a minute tubercle. There 

 is also a prominent tubercle behind each spiracle (excepting that 

 upon the first segment), bearing a black hair at its apex. This row 

 of lateral tubercles is variegated with rose and yellow, and each is 

 surmounted by a jagged black line, which includes the black spiracle 

 in the area described by it. The ventral surface has the same ground 

 color as the dorsal, and is similarly marked with longitudinal stripes, 

 which are, however, less distinct than the above. The head is irreg- 

 ularly punctate, patches of the punctures being black, giving the 

 surface a mottled appearance. The general color of the head and 

 first segment is lighter than that of the other parts of the body. 

 The anterior segment has a yellow front margin, interrupted in the 

 middle by the median stripe already described. The legs are ringed 

 with black and yellow at the articulations, and are elsewhere more 

 or less spotted with black. Upon the antepenultimate segment are 

 two prominent black tubercles, one upon either side of the median 

 stripe, each bearing a stiff bristle at its apex; and similar bristles 

 are scattered over the dorsal surface of the succeeding segments. 

 The last segment with the corresponding prolegs is punctate with 

 black, and bears two smaller setose tubercles similar to those above 

 mentioned. The preceding pair of prolegs are irregularly striped
