EJ.

On July 24 th , several specimens were taken on the

 any considerable height.

 a grey band on the u.-s. of the h.-w. are subject to 

 variation, being sometimes distinct and occasionally 

 entirely wanting ; the spots too, are liable to the 

 same condition. 



The female, as in the preceding species, is much 

 scarcer than the male. 



Genus 3. OENEIS 



O. Aello. 



TIMES OF APPEARANCE. End of June and beginning 

 of July. 



HABITAT. Mts. Pepiori and Balme de la Frema, 

 near the summit ; and also at the Madone des 

 Fenetres, from a height of from 6000 feet upwards. 

 Not very common. 



On July 24 th 1889, I captured three specimens, very 

 worn, in the two first of these spots, and others were, 

 I believe, taken by our party at the time. I have 

 received information from a most reliable source, that 

 it has been taken at the Madone, in front of the 

 hotel doors !
