— I 6 2 — 



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

 attached as usual by fine silken tlireads. 

 Length 15 mm. Width 5 r. ni. 



Pieris occidentalis, Reakt. ChrysaUs. 



Form of /'. Rap(€ and P. Prolodici', and much resemhiing the litter. Its color 

 is cream white, the raised margin of th.irax a:id abdominal segments edged witli 

 yellowish i)rown. Head produce<l into a short sharp beak, as in other species of 

 Pieris. On the dorsum are some small black shining points, and very fine irriorations 

 of black are scattered over the wiiole surface. Thesi are scarcely visible without a 

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

 veins. Black points also indicate the spiracles. 



Length 20 mm. Width 6 mm. 



From some specimens fouiul in Sier. Neviida, Cal., Sept. 1884. The 

 imagos emerged early in October. 



Callidryas Philea, L. Chrysalis. 



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

 series of waved fine lines, and are elevated in the middle to a sharp ridge. The centre 

 of the body, i. e. at the junction of tiie 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 

 TVr/rtj and other species of this genus. 'I'his is smooth, subu!a'e, roughened a little 

 at the extremity, where it is dark brown in col(jr. 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 hinnan form. The veins of the wing are distinctly seen through the wing- 

 cases. The anal segment is elevated on the margins, and the cremaster is rough, at- 

 tached by a coarse, strong, silken web. 



Length, iiicl. benk, 45 mm. Wiiltli, iiicl. wing-cases, 20 mm. Length of wn'ng- 

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

 cases, 8 mm. 



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



Thecla halesus, Cram. Chrysalis. 



IJroad, short and stout, abruiHly 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 few short 

 scattered hairs. 



.' ngth 18 mm. Width 6 mm. 



Chrysophanus xanthoides, Bois. E^S- 



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, Fab. Chrysalis. 



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

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