— I 6 2 — 



cremaster is rough, with 4 small winged processes, and an elevated ridge in its centre, 



attached as usual by hue silken threads. 

 Length 15 mm. Width 5 1. m. 



Pieris occidentalis, Reakt. Chrysalis. 



Form of /'. Rapa and /'. Protodice, and much resembling the Litter. It- color 

 is cream white, the raised margin of thorax and abdominal segments edged with 

 yellowish brown. Head produced into a short sharp beak as in other spi 

 Pieris. On the dorsum are some small black shining points, and very fineirrio atio is 

 of black are scattered over the whole surface. The-- are scarcely visible without a 

 lens. On the wing-cases are 7 row- of black points, indicating the course of the 

 veins. Black points also indicate the spiracles. 



Length 20 mm. Width 6 mm. 



From some specimens found in Sier. Nevada, Cal. , Sept. 1884. The 

 imagos emerged early in October. 



Callidryas Philea, L. Chrysalis. 



Color pale drab, darkest about the abdomen. The segments are marked with a 

 series of waved fine lines, and are elcv.it -d in the middle to a sharp ridge. The centre 

 ot the body, i. e. at the junction of the thorax and abdomen is greatly depressed into 

 a hollow. The thorax is shining, but bears a few roughened waved lines, most ap- 

 parent anteriorly. The head is produced into a very long (12 mm.) beak, as in 

 Terias and other species of this genus. This is smooth, subulate, roughened a little 

 at the extremity, where it is dark brown in color. The wing-cases are enormously 

 large, and very much extended above the abdomen. Looked at sideways, with the 

 wings downward, the chrysalis bears a fancied resemblance to a hammock swung. 

 bearing a human form. The veins of the wing are distinctly seen through the wing- 

 cases. 'I he anal segment is elevated on the margins, and the cremaster is rough, at- 

 tached by a coarse, strong, silken web. 



Length, incl. beak, 45 mm. Width, inch wing-cases, 20 mm. Length of wing- 

 case from base, 22 mm. Width of wing-case, 14 mm. Width of abdomen below wing- 

 cases, 8 mm. 



From specimens kindly given me by my friend Wm, Schaus, Esq., Jr. 



Thecla halesus, Cram. Chrysalis. 



Broad, short and stout, abruptly narrowing towards the two posterior segments. 

 Color snuff-brown, irregularly blotched with black over the whole surface, partic- 

 ularly at the extremity of the wing-cases. The posterior segments bear a lew short 

 scattered hairs. 



Length iS mm. Width 6 mm. 



Chrysophanus xanthoides, Bois. Egg. 



Almost spherical, but slightly flattened at the base, cream white, delicately retic- 

 ulated over the whole surface, the reticulations forming somewhat deep pits between. 

 From two specimens laid in my collecting box some years since in 

 California. 



Argynnis Bellona, Lab. Chrysalis. 



Lawn color, with a few irregular darker lines. Thorax with 6 raised shining 

 points, the posterior pair the largest. On each of the 3 middle abdominal segments
