duced this butterfly first appeared. I do not try to explain these 

 things, I simply state the facts without comment.

 All these examples figured here were taken by me at the time 

 the species was discovered, twenty-four years ago. I captured 

 eighteen on that day, but have not been back to the locality after 

 more since. I found the butterfly feeding on the flowers of 

 Bigelovia intricata, and I thought at the time that it probably was 

 the larval food-plant. Wrighti, male, has the sex-mark, the same 

 as Candida. And there is another mark, not heretofore mentioned, 

 that is peculiar, namely, the lighter-colored rays from base to 

 margin, on the underside of hind wing, as shown on the plate, in 

 figure c. These rays are raised above the general surface of the 

 wing, like ribs. The same feature, still more marked, is seen in 

 the figure of Eunus following. 



413. Copaeodes Myrtis. 



No figure. 

 Myrtis is from Arizona, where it is but scantily found. I have 

 never taken one, nor have I one in my cabinet. It is said to 

 greatly resemble Procris, but is a little darker. It is probably 

 a Mexican species. 



414. Copaeodes Eunus. Never previously illustrated.

Eunus is the largest Copaeodes of the country, and it is very 



rare as well. In my cabinet there is no male that shows the discal 



sex-mark, and I think that Eunus has not the discal dash, as 



Procris has not. The underside in figure c shows the raised, light-
