narrowly between the ninth pair, ending just in front of and between 

 tlie penultimate or tenth pair. The first patch then is composed of tliree 

 sections or saddle-shaped dilatations, of which the last or third extends a 

 little way down the sides of the plateau, and there are two divisions of 

 the second patch, the first the larger, and extending down the sides of the 

 plateau, but not so far as the third division of the first or anterior patch. 

 Between the first pair of papulae is a greenish median, transverse spot, 

 and on each side of the first section of the purple patch are two greenisli 

 dots like a stunted exclamation mark. These dots appear to be modified 

 surface dorsal piliferous warts, but they bear no hairs. A few fine pllifer- 

 ous tubercles are scattered along the sides of the body. On the middle 

 section of the first or anterior purplish patch are four rounded, impressed, 

 modified, greenish warts, and on the third section there are six of them. 

 On the posterior or second patch the first and larger division bears four 

 such round greenish spots, with a darker centre representing an aborted 

 hair, and on the last division are two similar spots. The last two pairs of 

 spots are connected by a faint line of the same color. The three anterior 

 pairs of papulae which increase in size to the third pair are all bright, del- 

 icate cherry or vermilion red. The three last pairs are of the same coloj-, 

 except the last pair which are green at base ; of these three the middle pair 

 (the tenth pair of all) are longest and highest, being twice as long and 

 high as the ninth pair. The fourth and fifth pair are very small and 

 green, while the sixth pair are somewhat larger than the two pairs in front, 

 and the two pairs behind, and tinged with bright reddish. The papulae 

 are all densely spined, the spines stiff and sharp and blackish at the ends, 

 greenish at the base. On each side, low down, is a row of nine small, 

 spiny papulae, rather difficult to detect as they are concolorous with the 

 body. Directly below them are the minute, pale, circular spiracles. The 

 papulae are situated on a ridge, while the spiracles are just below it. Be- 

 tween the papulte is a pale lemon-yellow streak. The plateau is yellow- 

 ish green above and on the sides, while the sides are dark pea-green. The 

 skin of the entire body is finely granulated. 



This larvae indicates in some points of its structure its descent and that 

 of the group to which it belongs, from the Attacinae ; these points are the 

 setiferous tubercles, and the distinctness of the segments from one another, 

 the sutures between them being well marked. Adoneta is one of the more 

 generalized forms, while Limacodes (scapha) and Heterogenea seem to 

 be the most modified, specialized or aberrant forms. Hence Adoneta, 

 etc., are more like the probable ancestors of the group than any other 

 genus. 



Several singular microgaster cocoons occurred on some individuals, 

 being white and projecting vertically from the back.
