THE CANADIAN ENTOMOLOGIST. O 



Body, above, reddish browa, with many longitudinal lines and stripes of a 

 somewhat darker shade. A double, whitish dorsal line, with a stripe on 

 each side of the darker shade of brown ; another stripe of the same hue 

 close to stigmata, and between these are faint longitudinal lines. Spaces 

 between segments from fifth to eighth, nearly black above ; this, however, 

 is only seen when the body is coiled up, which the larva readily does when 

 disturbed. 

 Under surface slightly darker than upper, with many longitudinal lines of a 

 still deeper shade, and a central stripe of blackish green from 6ih to 9th 

 segments; feet and prolegs greenish, semi-transparent, with faint lines, and 

 dots of a darker shade. 

 This larva has only three pairs of prolegs, and in its movements resembles the 

 true Geometer's. Early the following spring the chrysalides produced the 

 imago. 



During the summer of 1866, late in July or early in August, a female 

 specimen of that very rare moth, Arctia pavthenos, was captured by Mr. B. 

 Billings, of Ottawa. While confined in a box it deposited a number of eggs, 

 which, a few days afterwards, produced the young larva. These fed readily 

 on lettuce and other herbaceous plants, so that they were reared without dif- 

 ficulty until they were about half or two-thirds grown. The season was now 

 advanced, and they refused to eat any more. At this period of their growth 

 it appears they hybernate for the winter, hiding in crevices, and under loose 

 pieces of bark on trees, &c., and finish their growth the following spring. For 

 want of circumstances favorable to their preservation many of them shrivelled 

 up and died. Several specimens were sent to me to see if I could winter 

 them, and from one of these the following description was taken: — 

 Length, 1.25 in., cylindrical. Head medium sized, bilobed, black and shin- 

 ing, with a few brownish hairs. Body, above, black, with transverse rows 

 of shining tubercles, rather large, and of a dull, brownish-white color, ex- 

 cepting a few on anterior segments, which are black. From each tubercle 

 arises a tuft of brown hair. The hairs on anterior segments and around the 

 base of body are rather short, the others long, silky, of a slightly paler 

 shade of brown, and extending backwards, overhanging the segments be- 

 hind them. Stigmata elongated, and of a yellowish orange color. 

 Under surface black, with a slight brownish tinge; 5th, 6th, 11th and l2th 

 segments, with a transverse row of black tubercles in continuation of those 

 above, each emitting several short, dark brown hairs. Feet black, banded 

 with whitish brown ; prolegs black without, tipped with greenish brown. 

 I was unfortunate with my specimens; Mr. Billings was equally so. Mine 

 were buried in a box, under the ground, thinking this would preserve them 

 in a uniform state of moisture. When taken up in the spring, two of them
