cal appendages, brown with black hairs ; they are retractible into the 

 abdomen, and so often not visible. Legs yellow, sprinkled with black, 

 and with black hairs ; hind femurs sometimes fuscous in middle ; tip of 

 tibiae and of the joints of tarsi blackish ; spurs brown, as long as the two 

 basal joints. Wings long, broad, hyaline ; pterostigma yellowish ; veins 

 fuscous interrupted by pale yellowish ; transversals along the median and 

 submedian pointed with fuscous ; the points above the submediana are 

 larger and more numerous, forming nearly a serrated black line ; also the 

 gradate veins going from the end of the submediana upwards and out- 

 wards to the tip of wing form often a brown line, more or less visible ; 

 the smaller forks along the hind margin dark ; costal space of front wings 

 only with a few forked transversals before the pterostigma ; hind wings a 

 little shorter, narrower, nearly hyaline.

There are 40 specimens before me of both sexes. In the small town 

 Ainsworth, in the middle of a sandy desert, the windows of the office in 

 the little inn where we had to stay the night, were literally covered with 

 specimens. This species belongs to the west of the Rocky Mts. The 

 specimens from Mexico — Matamoras — are smaller than the others, but not 

 different. 



The Butterflies of North America, by W. H. Edwards. Part 

 iv. of the Third Series has recently been issued. It contains the usual 

 three magnificent plates ; the first represents both sexes and several varie- 

 ties of Colias Chrysomelas, the second the upper and under surfaces of 

 both sexes of the lovely Argynnis JVausicaa, and the third fully illustrates 

 all the stages of Ccenonympha Galactinus, form California. The letter- 

 press contains much interesting matter on the life histories, in addition to 

 the descriptions of the species.
