wild, appearing at the beginning of April and lasting to the end 

 of June, but is a decidedly rare insect. This would represent the 

 spring brood. In the Brooklyn Bull, the species is recorded from 

 Utah ; Mr. Mead quotes it from Owen's Lake, Cala. 



Colias Alexandra.

There are before me a male and a female named by Mr. W. H. 

 Edwards, 7 specimens from Ft. Hays, Kansas 2000', June 12 to 27, 

 and 3 specimens from Montgomery, Col., 11,000 ft., all collected 

 by Mr. J. A. Allen, and one type from Colorado by Mr. Reakirt. 

 About a dozen more have been communicated to correspondents. 

 The species was not rare in these localities in 1871. 



Messrs. Reakirt, H. Edwards, Strecker, and the author of the 

 paper published by the Brooklyn Entom. Soc, suppose that 

 C. Edwardsii may prove to be a variety of C. Alexandra. 

 The most careful examination of the text and the figures in N. A. 

 Butt. Colias I, and the specimens show no difference of any impor- 

 tance. The characters given by Mr. W. H. Edwards are the 

 greenish tinge on the inner half of the secondaries ; fringe yellow ; 

 primaries with a broad black band ; no pink tinge at the base of 

 the secondaries below; discal spot of same wings below silver- 

 white, without a border. 



A comparison of the characters given above for C. Edwardsii 

 will show that they contain every one considered as peculiar to 

 C. Alexandra. The size and the cut of the wings vary in the 

 same limits. Therefore C. Alexandra and C. Edwardsii belong 

 to one and the same species. C. Alexandra is said to have only 

 one brood in the season ; but with the single exception of Ft. 

 Hays it is observed on considerably higher elevations than C.
