266 LEPIDOPTERA. 



extending entirely around the body. The chrysalis is .32 of 

 an inch long, and .15 wide. It is fastened with a silken 

 thread. The abdomen is thickened and somewhat raised. It 

 is minutely hairy, pale brown, with many dots and patches of 

 a darker color ; the upper edge of the wings being quite dark, 

 with a dark ventral stripe, and four or five short, dark lines on 

 the side, It remains in the chrysalis state eight or nine days, 

 the caterpillar turning dark July 3d, just before pupating." 

 The body, especially the abdomen, is thicker and fuller than in 

 Chrysophanus Americanus. 



TJiecla Mopsus Hiibner is found in New England and Canada. 

 Mr. Saunders sends me the following description of the larva 

 taken June 9th, by beating bushes, at London, Canada. "It 

 was .40 of an inch in length. The head is small, of a shin- 

 ing black color, with a pale stripe across the front just above 

 the mandibles, and is drawn within the second ring when at 

 rest. The body above is green along the middle rings, deep rose 

 color at each extremity, and is thickly covered with short, brown 

 hairs. The second segment is rosy above, greenish yellow at 

 the sides, with an edging of the same color in front ; the third 

 segment is entirely rose colored ; from the third to the tenth 

 segments is a dorsal stripe of rose which is wide on the fourth, 

 fifth, eight and ninth segments, but narrow and linear on the 

 intermediate ones ; on the tenth segment the green encroaches 

 on the rose color on the sides of the body, extending more than 

 half-way upon the segment behind the tenth. The body is 

 rose colored with a dorsal streak of a darker shade. The rose 

 color at each extremity is united by a rosy line along each side 

 close to the under surface which grows fainter on the middle 

 segments. The under surface is dull green, with a yellowish 

 tint; the feet and prolegs (abdominal legs) are yellowish 

 green. June 24th, the larva has now become quite large and 

 will probably soon go into the chrysalis state. I found it 

 would readily eat the plum and cherry. 



"Its length is now .70 ; its width about .20 of an inch. The 

 head is very small, bilobed, black and shining, with a streak of 

 dull white across the front above the mandibles, which are 

 reddish brown. The body above is dull green, with a yel- 

 lowish tint, especially on the anterior segments, which are
