106 THE CANADIAN ENTOMOLOGIST. 



species. I believe Mr. W. H. Edwards has done so. Females confined 

 over fresh violets oviposited readily, and in 1893 a number of larvas were 

 brought to Illinois, and subjected to " the cold-storage process " for the 

 winter. In the spring, however, they failed to awaken from their lethargic 

 condition, 



A. euryjiovie was very common on low lands near Park City. At 

 least 600 were taken in 1893. In one open meadow covered with flowers 

 there were thousands of this species. Two forms or varieties were found, 

 the ordinary one with silvered spots below, and a variety with all the 

 spots below yellow. The ratio was about one yellow form to twenty-five 

 of the silvered. A remarkable fact was noted. A silvered $ and a 

 yellow $ were taken in coitu ; a yellow ? and a silvered $ ; a silvered 

 $ and a silvered S , and also a yellow 9 and a yellow (^ . I am positive 

 of all the statements except the last concerning the yellow ? and yellow ^ . 



We know that peculiar specimens are sometimes the result of 

 hybridism. Melanism may result from cold, drought, etc., and almost 

 everyone has seen " sports " in the insect world. 



I await with interest the results of future study concerning these 

 subjects. It is commonly asserted that hybrids are never fertile. Is this 

 k7io'wn to be true ? 



A. myritia was abundant in the meadow mentioned above, but I do 

 not remember having seen it elsewhere in Utah. 



A. epithore was found on low ground flitting among the leaves of 

 a large canna-like plant. One specimen also was taken beside a small 

 mountain stream. 



A. kremhild was taken in the same locality. 



A. egleis was taken on a hillside near town, in an open spot, where 

 the sun's rays seemed to linger at eventide, but near the underbrush where 

 it was easy to escape among the scrub oaks and sage bushes. In its 

 habits it much resembles A. coronis. 



A. coronis was rare at Park City, but more common in the mountains, 

 near Salt Lake City and Ogden. 



A. Nevadensis and A. Meadii were also rare at Park City, but more 

 abundant near Salt Lake. In habits they were quite unlike coronis and egleis, 

 always being found on the flowers or else crossing swiftly to some place 

 where flowers were more numerous, never dropping to the ground and 

 fluting below the sage bushes, but seeking escape in swift flight. They 

 also seemed to prefer lower ground, — the valleys instead of the hillsides.
