rather dark specimen had all the spines reddish orange at base, giving tte 

 whole body a reddish hue. 



These larvEe remained in the chrysalis state eight or nine days. The 

 imago is usually found common throughout July and August, and the larvae 

 plentiful in September. It is quite likely that this insect may also pass the 

 winter in the imago state, although I have never found it hybernating, or 

 taken it on the wing very early in the season. 



Limenitis disippus, Grodt. — Larva found feeding on willow, July 24th. 



Length one inch and a quarter. Head rather large, flattened in front, 

 strongly bilobed, pale green with two dull white lines down the front and 

 roughened with a number of small green and greenish-white tubercles. Each 

 lobe is tipped with a green tubercle, or .short horn, larger than any of the 

 others on head. Mandibles brown, tipped with black. 



Body above dark rich green, with patches and streaks of dull white ; 

 second segment smaller than head, with many minute whitish tubercles; 

 third segment dull whitish-green, raised considerably above second, with a 

 flat ridge above having a long brownish horn on each side of it, thickly 

 covered with very short white and brown spines; fourth segment about the 

 same size as third, with the same kind of ridge above, with a small tubercle 

 on each side capped with a bunch of -short whitish spines ; between the 

 ridges on third and fourth segments are two small black dots above. Each 

 segment from fifth to thirteenth inclusive has two tubercles, one on each 

 side, and in a line with the long horns on third segment, each crowned with 

 a cluster of whitish spines ; tubercles on sixth and twelfth segments much 

 larger than the others, those on eleventh and terminal segments next in size, 

 the latter placed on the anal lid and nearer together than those on thé other 

 segments, — those on the ninth are smallest. Tubercles on seventh, eighth, 

 tenth, and eleventh segments with a streak of white at their base; each seg- 

 ment behind fourth, excepting ninth, has several smaller tubercles of a bright 

 blue color. A large whitish patch covers nearly the whole of ninth and 

 parts of eighth and tenth segments, and another of a similar character covers 

 the second, third, and part of the fourth. A white stripe extends along 

 each side close to under surface from fifth to terminal segments inclusive, in 

 which is set a small cluster of whitish spines about the middle of segments 

 from sixth to tenth. On each side of seventh, eighth and tenth segments is 

 an elongated blackish spot, just above and behind spiracles ; terminal segment 

 with two dark greenish-brown spots above, anterior to the tubercles. Spira- 

 cles rather large, oval, brownish-black. 



Under surface whitish-green, with a central dull-white stripe on hinder 

 segments; feet brown, ringed with brownish black; prolegs pale greenish, 

 faintly tipped with brown.
