small, but those corresponding to the first lateral larval spines a^e large 

 on the anterior segments and gilded ; colors dull green, brown and pink 

 ish white ; the head case and mesonotum green, and on wing cases a 

 broad band of same hue ; on the side of abdomen from wing case to tail 

 a darker green stripe; remainder of wing cases pink tinted, and all the 

 anterior parts are more or less mottled with pink-brown ; on dorsal side 

 of abdomen a pink strip© and on the sides some oblique pink lines. The 

 butterfly emerged after 8 days. 



There is much variation in both larva and chrysalis. The foregoing 

 description is drawn from examples obtained from eggs sent me by Mr. 

 C. H. Roberts, at Factory Point, Vermont, in May, 1878. There were 

 nine eggs, and besides the larvae from these, Mr. Roberts sent two others 

 half grown. All these larvae were much alike, and they differed so much 

 from other Progne larvae which 1 found at Hunter, in Catskills, in July, 

 1877, that I did not believe they could be of the same species. In fact, I 

 thought I was feeding the larvae of Gracilis, a species allied to Progne and 

 Zep/iyrus, and whose preparatory stages must be closely like those species. 

 These Catskiil larvae were found on a currant bush near, the house at 

 which I was residing. They were four in number, all past last moult and 

 alike ; the general color was buff, marked with black ; the anterior half of 

 segments 3, 4, 5 was of a more sordid buff; on 6 began to appear imper- 

 fect black bands, which on the middle segments were complete and con- 

 spicuous, but on the posterior ones were somewhat indistinct as well as 

 broken (these were the V-shaped and oblique bands before spoken of) ; 

 also on the anterior edge of each of these segments, fronting the dorsal 

 spine, was a small black patch ; on the posterior part of segments 3 to 12 

 were narrow transverse stripes, 8 in number, the 1st, 3rd, 5th and 7th of 

 which were black, the 2nd and 8th yellow-buff, the 4th and 6th gray-buff^ 

 of these the yellow were most conspicuous; on the sides of 6 to 12 wasa> 

 large fulvous patch on each which crossed the bases of 2nd and 3rd 

 laterals, and between these two rows was a black band on which were the 

 spiracles ; in line with third laterals was a narrow buff ridge, buff except 

 where it crossed the fulvous patches ; and a black band ran along -base 

 of body, covering the upper part of the pro-legs ; the dorsal spines were 

 whitish, in part pink at base ; the first laterals were black and white, 3, 4, 

 5 and 7 being black with some white branches, the others white with 

 black tips ; the second laterals were all black, and the third were either 

 white or bku k with white tips ; the face was black and red, along the cleft
