very scarce, then disappears until the advent of the second brood early 

 August. I have several times kept the chrysalis of this insect over the 

 winter, but they have invariably produced ichneumons in the spring. 



Vanessa Milberti. — A description of the larva of this species was first pub- 

 lished by myself in the second volume of the Proceedings of the Entomological 

 Society of Philadelphia, page 28, but as this was unsatisfactory from its 

 brevity and incompleteness, I have re-described it with fuller details. 



Larva taken nearly full grown July 26th, feeding on nettle. 



Length one to one and a quarter inches, cylindrical. 



Head black, thickly covered with fine brownish white hairs, and sprinkled 

 with many minute whitish dots. 



Body above nearly black, thickly sprinkled with small white dots and fine 

 whitish hairs, giving it a greyish appearance. Each segment, excepting the 

 second has a transverse row of branching spines — on the third and fourth 

 segments, four — fifth segment six, and from fifth to terminal segments, seven. 

 Terminal segment with two pairs, one pair behind the other. A greenish 

 yellow lateral line, close to under surface, and above this a second broken line 

 of a brighter orange yellow shade. All the spines and their branches are 

 black, excepting the lower rows on each side from fifth to twelfth segments, 

 these springing from the greenish yellow line are of a greenish yellow color. 



Under surface dull greenish, with minute whitish dots. A wide central 

 blackish stripe covering nearly the whole under surface of anterior segments 

 — feet black and shining, prolegs green. 



This insect I believe passes the winter in the imago state. I have taken 

 it on the wing as early as the 24th April. It is double brooded ; the first 

 brood of larvae reaching maturity about the middle of June, appearing in the 

 imago state about ten or twelve days afterwards. The second brood of larvae 

 are full grown during the last week of July, and appear in the perfect state 

 early in August. 



Vanessa interrogationis. — Larvae of this species full grown and partially 

 grown were found together on the 7th August, feeding on the hop. 



Description of young larva. Length half an inch. Head black. Body 

 above black, with transverse rows of branching spines, those on third, fourth 

 and terminal segments black, with a row of the same color along each side 

 close to under surface. All the other spines pale whitish. 



Under surface nearly black with dots of a pale hue. 



Full grown larva. Length one and a quarter inches. Head reddish black, 

 flat in front, somewhat bilobed, each lobe tipped with a tubercle, emitting 

 five simple black pointed spines. Head covered with many small white 

 tubercles mixed with a few blackish ones.
