Lurra, Star/e 7/7.— Lciigtli, 10 iiiiii. The head is still large, iiiiicli wider tliaii tlie body, and 

 green, with a ])urple stripe on each side. Tlie yellow lines are more distinet Ihan before, and the 

 body has a purplisli tinge. (Described from liridghani's figure (PI. Vlll, fig. — ) observed 'hily 8. 

 Larva, Stage IV. — Length, 1*0 mm. In one observed July 20, and nearly full-grown, the head 

 is still without the lateral black stripe, and the two subdorsal yellow stripes aic very distinet, but 

 there are no ])ink spots anywhere on the body. The small spiracles are pale orange. 



In another drawn by Mr. Bridgham (PI. VIII, tig. 4), and also 20 mm. in length, the head is 

 not banded, but the body isprettily spotted with pinkish red, iuthe following manner: Two round 

 dorsal spots on the first thoracic segment; a broad pinkred transverse band on the sec( nd and 

 third thoracic segments, each broken into two by a transverse median whitish line; on abdominal 

 segments 3-9 is a pair of dorsal red, rounded spots, growing larger and more di.stinct toward the 

 end of the body, there being four spots on the ninth segment. The subdorsal yellow lines are 

 well marked. 



Larva, last (lifth) ufage. — Length, 30 mm. One found on the asjien August 0, was pale green, 

 near the color of tiie underside of the leaf. Head ' smooth, polished, darker green than the 

 body, with two black stripes on each side, not meeting above on the vertex. Body green, tapering 

 at each end, smooth, nearly hairless, with no j)iliferous warts, the scattered hairs being miuute; 

 two fine subdorsal yellow lines, and Dyar has observed a faint whitish substigmatal line on 

 second and third thoracic segments. Thoracic segments 1-3 each with dorsal pink-red blotches 

 or spots, two on the prothoracic segment, while those behind are not so divided. Abdominal 

 segments 3 to 9 each' with a conspicuous pink-red dorsal square spot, the space between the spots 

 more or less yellow; none on the suranal plate, which is smooth and rounded, while the two 

 subdorsal yellow lines do not meet on it; no spots or dots on the side of the body below the 



subdorsal lines. Thoracic and abdominal legs of the same color

M (l\ \/ Cocoon. — A very slight web of silk spun between two leaves,

female cocoon, which measures about 22 by 20 mm. The pupa lies very 



loosely in its cocoon. 



Pupa. — Length, l.j-l(i mm. Of very unusual shape, being flattened oval cylindrical; posterior 

 end of theljody (fig. .53) much rounded and blunt, smooth, with no distinct traces of a cremaster, 

 much less than in other pupre inclosed in cocoons; surface of the body rather smooth, less 

 pitted, and the minute pits or punctuations more distinct and numerous on the dorsal than on the 

 ventral surface. In color dark brown, much darker than usual in Xotodoutiaus or other moths. 



Llahits. — The eggs are laid the last of ,Iune and during the first week in July in Maine, 

 and probably two weeks earlier in southern New England. There are apparently five stages, 

 and the duration of Stage I is about three days, as is that of Stage II, and that of Stage III 

 about five days. 



One larva July 26 spun a very slight cocoon between two leaves, and jiupated July 28. On 

 this caterpillar there were no red spots. 



The moth appeared in the breeding box at Providence May 30, having been brought from 

 Maine in the pupa state: another one appeared June 1, also from Maine, in the larva state. 



Mr. Howard L. Clark has reared this moth from caterjiillars found on the IJalm of Gilead at 

 Warwick, E. I. The moth appeared July 22, having been in the chrysalis state about ten days. 



Itiley states (MS. notes) that the moths occur in May, June, and July. Mr. G. H. Hudson 

 gives the following dates of capture of the moths at Plattsburg, X. Y.: May 22. 1 ; May 29, 1 ; 

 June 3, 1; June 5, 1; June 7 to 24, 22; July 10, 1; July 10, 1; July IT, 1; July 2(t, 1, July 27 to 

 August 13, 30. 



' Dyar's measurements of the width of the head for the last four stages are as follows: Calculated, 0.48, 0.74, 

 114,1.75,2.7 mm. Ratio, 0.65. Fouud, 0.7, 1.2, 1.7, 2.7 mm. (Psyche, vi, 147.)
