light rust-brown color along the abdomen, and a perfectly round spot of the same color on the top 

 of the thorax, this spot generally giving forth a narrow orange line posteriorly. 



Perfect Insect. — Average length 0.55 ; alar expanse 1.0S. Fore wings bright lustrous golden- 

 orange, crossed transversely with irregular bands of sulphur-yellow spots on a black ground as in 

 the figure ; fringes dense, narrow and brown. Hind wings smoky black, sub-hyaline except near 

 apex and along margins ; veins dusky, fringes also. Under surface of front wings dusky brown 

 with the colors of the upper surface partly visible ; under surface of lower wings concolorous. 

 Head black with sulphur-yellow tufts ; eyes black; palpi alternately black and sulphur-yellow ; 

 antennas filiform, slightly serrate, black with a white shade along the upper terminal third. Tho- 

 rax black with a wavy sulphur-yellow collar, golden-orange shoulder-covers with a spot of the 

 same color between them, and two sulphur-yellow spots below this last. Abdomen steel-blue 

 above, with a large brimstone-yellow patch on each segment below. Under surface of thorax black 

 with brimstone-yellow patches ; legs black, the front pair with yellow coxa and orange thighs, the 

 other four with more or less yellow, especially on the thighs. 



Described from numerous specimens. No particular sexual difference, except in the form of 

 the body. 



THE WALNUT TORTPJX, Tortrix Riley ana, Grote— PL 2, Figs. 3 



and 4. 



(Lepidoptera, Tortricidse.) 



During the month of May large bunches of the leaves of the 

 Black Walnut and of the Hickory may be found drawn together by a 

 silky web, and living within these bunches, a nest of caterpillars of a 

 [Fig 85.] yellow color and marked as at Figure 85, a; b showing 

 a side view of one of the segments. During the latter 

 part of the month they change to little honey-yellow 

 Ichrysalids, within the nest, and by the middle of June 

 these last work their way through the leaves to the 

 outside, by means of rows of minute teeth which they 

 have on the back. Here they hang in great numbers 

 by the tips of their abdomens, and in a short time the moths escape. 

 This moth is represented at Plate 2, Figure 3, with the wings ex- 

 panded, and at Figure 4 with wings closed. It is prettily marked, the 

 fore wings being of an ochreous color with a golden tint, and darker 

 spots, and the hind wings of a deep golden color. It was first de- 

 scribed by Mr. Grote, of New York, in the Transactions of the Amer- 

 ican Entomological Society, Vol. II, p. 121. It was quite common in 

 1868 along the Iron Mountain road, and seems to be peculiar to Mis- 

 souri. It also seems to prefer the young Hickories and Walnuts to 

 the older or larger trees, as I found few nests that were out of reach. 

 On the Snowberry * (Sym/pJioricarpus vulgaris), similar nests 

 may be found at the same time of year, containing caterpillars agree- 

 ing in description with those feeding on the Wa'nut and Hickory, ex- 

 cept in being smaller. They go through their transformations in the 

 same manner and produce moths similarly marked but uniformly 



i»y also occur on the Ironweed (Vernonia fasciculata), though I have not bred the moth 

 from worms feeding on this plant.
