Mr. Moeschler, Wien. Ent. Mon., Vol 4, p. 354, records two 

 varieties of the male from Labrador. One has the disc of all 

 wings orange, the other has the j>riuiaries entirely orange, and 

 the secondaries orange on the disc ; the discal spot of the prima- 

 ries is black, of the secondaries very large and orange. In the 

 Brooklyn Bulletin, March, 1879, C. Pelidne is quoted from 

 Alaska ; by Mr. H. Edwards from Alaska, Sitka and from the 

 mouth of the Yukon river, and also C. Palaeno from Alaska.

 The couple figured is said to be from the Mackenzie's River in 

 the two first works, from the Great Slave Lake in the Catalogue 

 and Synopsis. The number of specimens is not stated. Pro- 

 fessor Zeller' s opinion, of which Mr. H. Edwards believes, " it is 

 more than probable that he is correct," is that C. Chippewa is a 

 form of C. Palaeno, similar to those of the Swiss mountains. Mr. 

 Strecker affirms also the identity of C. Chippewa and C. Palaeno. 

 Comparing the description and the figures with a number of 

 Palaeno from Labrador and the Swiss Alps there is no reason to 

 doubt the truth of these statements. It should be remembered 

 that Mr. W. H. Edwards at the time of his publication has prob- 

 ably not been able to compare C. Palaeno from North America. 



Conclusions. 



The species of Colias found in North America are from our 

 actual knowledge as follows : — 



1. C. chrysotheme = Keewaydin. 



Seasonal forms Ariadne and Eurytheme. 



I remark that Professor Zeller, when he wrote the quoted criti- 

 cism (Stett. Ent. Z. 1874, p. 437) could not have any knowledge 

 of Mr. Boll's discovery, published in 1876.
