yellow spots. Lateral lines four or six in number, black, interrupted with yellow or 

 orange; intermediate spaces yellow. Head black, slightly marked with yellow. 

 Belly dirty gray, spotted and marked with black and white. Feet and prolegs 

 yellowish, with black markings. Full fed the beginning of September. In appear- 

 ance strongly resembles the larva of Liparis Salicis. In habits allied to the larvae of 

 the genus Acronycta. The eggs are flat and yellow. The pupa is enclosed in a 

 cocoon of gnawed bark or rotten wood. It is dull red and very like that of A. 

 Alni. — H. Harpur Crewe; The Rectory , Dray ton- JBeauchamp, Herts, October 27,

Description of the Larva of Acronycta tridens. — Does not roll in a ring or feign 

 death when disturbed. Body somewhat incised at the interstices of the segments, 

 hairy, and having a conspicuous hump on the 5th and I2th segments. Head black, 

 shining, but emitting so many hoary hairs, as to give it a gray appearance. Body 

 black, beautifully ornamented with orange and snow-while markings : 2nd segment 

 black, with a small median white spot on the back ; 3rd and 4lh segments slightly 

 tumid on the back, the centre of each swelling being orange-yellow ; on each side of 

 each of these segments is also a bright orange spot ; 5th segment with a conspicuous 

 median hump, velvety black on the summit, but hoary behind, and having one while 

 spot on each side ; a little distance below this is a pair of while spots closely 

 approximate and on each side of them a larger orange spot ; on the 6tb,7th, 8th, 9th, 

 lOlh and 11th segments is a median stripe, rather narrowed, entire, and of an orange- 

 yellow colour in the centre of each segment, rather dilated, longitudinally divided and 

 dingy white in the interstices : on each side of each segment, below this median stripe, 

 are two white spots, one above the other, like the colon in priming, and there are three 

 orange spots of different forms below the lower of these white spots; the 12th 

 segment is decidedly humped, and has a conspicuous snowy white mark on ihe sum- 

 mit shaped something like a cross, but the hinder radius of the cross is sometimes 

 wanting; the hind margin of this segment has a broad orange border; the 13th seg- 

 ment terminates in a kind of horn, quite black and directed backwards : below 

 the lateral series of orange spots I have described, is a lateral stripe mottled with yel- 

 lowish markings, among which are situated the spiracles, and below this again is 

 a slender interrupted orange stripe. Feeds on Beiula alba (birch), and is full fed on 

 the 8th October. — Edward Newman. 



Description of the Larva of Acronycta Psi. — Head rather large. Body hairy, 

 with parallel sides, but humped on the back ; the first hump is slender, long, erect, 

 hojn-like, and sealed on the 5th segment; the second hump is shorter, broader, and 

 on the 12th segment. Head black, hairy, shining, its divisions very convex ; 2nd 

 segment black, with a very narrow median yellow line; 3id, 4th, 6th, 7th, 8th, 9th, 

 10th and 11th segments with a broad median yellow stripe and a median square spot 

 of the same colour on ihe hinder part of the 12th segment; the horn-like hump on the 

 5th segment is intensely black and clothed with crowded short black hairs, intermixed 

 with scattered long ones ; on each side of the median stripe is an equally broad jet-black 

 stripe, and in this on every segment, from the 5lh to the 12th, both inclusive, are two 

 transverse bright red spots, with two minute whitish warts between each pair, the 

 warts emitting black bristles: below the black stripe on each side is a broad 

 gray stripe emitting gray hairs, and including the black spiracles ; this gray stripe is 

 reddish on the anterior segments, the intensity of the red increasing towards the head.
