of taking water at damp places on the ground, where they are 

 gregarious, and are easily taken. 



The larval food-plant is Amorpha Californica, an anomalous 

 plant having a one-petaled blossom. The plant is limited in range, 

 and the butterfly is thereby also limited in range.

Bernardino is a variety of Eurydice ; was separated by W. H. 

 Edwards in 1887, from material sent him by me; and the variety 

 was based upon the following points : Smaller size, absence in part 

 of the violet reflection on fore wings, black border on hind wings, 

 as to males ; and in the female, the smaller size, and the series 

 of small points near the margin of all wings, on both upper and 

 under sides. 



This last point, as I have shown, does not always hold good. 

 Mr. Edwards thought that Bernardino was an early appearing 

 form; that, in fact, it was the early brood of Eurydice; but I 

 think it is rather the altitude than the season that counts in this 

 matter, for Figure a was taken in June ; and I have never taken a 

 Bernardino down on the low plains at any season. 



Preliminary stages as in Eurydice.

 Amorphae is a dimorphic female of Eurydice. There is no male 

 of this form : but it is simply one of those freaks, more or less
