I have given a full series of Ariadne, so complete that but little 

 remains to be written ; the figures explain themselves. Ariadne 

 is the winter form, small in size, and pale in the orange flushing 

 on the disk of the fore wings ; occasionally there is no orange to 

 be seen. 



The white female, as in Eurytheme and Keewaydin, is present in 

 constantly increasing numbers ; it has not been named, although 

 all distinct forms are supposed to be named. 



The larval food-plant that is preferred by Ariadne is a wild 

 lupine, Lupinus Minima. Ariadne is not often seen flying about 

 the alfalfa fields ; it seems to be in a wild or uncivilized state, as 

 yet, and chooses the wild plant.

 Keewaydin is intermediate in size and color between Eurytheme 

 and Ariadne, and is called the spring brood, but really it is found
