under surface extending around the posterior segments. In some younger 

 specimens these yellowish-white markings have a reddish or brownish tint. 



Under surface deeper bluish-green, with a faint white bloom. Feet and 

 prolegs partake of the general color. 



June 21st. — Since the 15th most of the lame have moulted, resulting in 

 some change in their appearance. 



Length '55 in. Head, color and markings as before. 



Body above dull white with a faint green tinge, changing in some speci- 

 mens to a slight ochrey-reddish tinge, thickly covered with minute white 

 hairs ; second segment pale green. The green dorsal stripe on third, fourth, 

 aud fifth segments has acquired a deep greenish brown tint, which contrasts 

 strongly with the general .color of body; the same change is also observable 

 on the last four segments, and here the stripe is much widened, the anterior 

 portion of it assuming the form of a triangular patch, its base on posterior 

 part of eleventh segment, its apex on anterior part of tenth; on the interme- 

 diate segments the dorsal stripe is obsolete. On the fifth segment a streak of 

 dark brown crosses the end of the dark dorsal stripe extending about half 

 way down the sides ; there is also a dot of the same color on each side of 

 this segment close to under surface. On the sides of the fourth and sixth 

 segments are several additional brown dots, very small. The tenth and 

 eleventh segments have an oblique brown streak on each side, with a small 

 spot of the same color placed below it. The sides of body have live or six 

 white oblique lines. 



Under surface green, with a whitish bloom; a patch of brown on each 

 side in continuation of spots on tenth and eleventh segments ; a patch of 

 the same also behind the last pair of prolegs. 



Before entering the pupa state these larvee assumed a delicate pink color, 

 the dorsal stripe becoming darker, the other lines paler. Length .60 in. 

 Head, color and markings as before. Body above dull whitish pink ; second 

 segment greenish ; dorsal stripe on third, fourth and fifth segments very 

 dark brown, widest on fifth, where there is a spot of the same color on each 

 side of it. The lines bordering dorsal crest, oblique lines on sides, and edg- 

 ing of under surface, all pale pink. On the hinder segments the anterior 

 portion of dorsal stripe is widened, assumiug the form of a triangular patch 

 as before, its color scarcely so dark as that on anterior segments. 



Under surface green with a yellowish tint, feet and prolegs of the same 

 shade. 



One of these became a chrysalis on the 27th of June. Length of pupa, 

 •40 in. Color pale brown, sprinkled with many dots of a darker shade, and 

 thickly covered with short yellow hairs. A ventral line of dark brown along
