234 THE CANADIAN ENTOMOLOGIST. 





at Coalburgh the butterfly is not very common, but I see several examples 

 every year about the flowers. It flies and behaves like Argynnis. The 

 female will lay eggs readily when confined with Violet or Passion-vine, but 

 prefers the latter, and if the two plants are offered the larva the vine is 

 preferred. The larvae of the summer brood mature rapidly, but those of 

 the fall brood probably hybernate when half grown. On 12th Septem- 

 ber, 1873, I obtained a number of eggs, part of which were laid on 

 Passion-vine, part on Violet. The caterpillars which fed on the vine grew 

 more rapidly than the others, and began to pupate 20th October, and this 

 continued for two weeks, up to 9th November. Between 25th November 

 and 5th December many butterflies emerged. Inasmuch as I have several 

 times seen Claudia flying on warm days in November. I conclude that the 

 butterfly must hybernate. But while the larva? fed on Passion-vine were 

 pupating, those on Violet were none of them mature and some were very 

 small, only past 2nd moult. I kept these in a warm room, giving them 

 all the sunlight possible. When the sun shone directly on them they were 

 active and fed vigorously, but when the sky was clouded they remained 

 quiet, sometimes for days together. All but one died before maturity, but 

 this one continued to feed at intervals till 22nd March, and died just as 

 pupation approached. I infer, therefore, that in favorable circumstances 

 the larvae would hybernate. 



The larvae of Claudia are exceedingly active, and travel with rapidity. 

 On one occasion Mr. Mead found a mature caterpillar on an alder, four 

 feet from the ground, resting during the day. No violet or known food 

 plant was near, and the caterpillar starved two days rather than eat alder, 

 and finally was fed violet. It was probable that it had travelled a con- 

 siderable distance to rest, and returned at night to its feeding place. 



The egg resembles closely that of Argynnis. and might stand in same 

 genus. The chrysalis resembles closely that of Melitaea. But the larva 

 is very unlike Melitaea, and almost as unlike Argynnis. The imago itself 

 looks like a magnified Argynnis Bdlona, and because it does, Hubner 

 placed the two in the same coitus. In Boisduval and LeConte the 

 species stands in Argynnis. I am not able to discover, by a comparison 

 of prepared wings of Claudia and of several species of Argynnis, any 

 difference in the neuration between Euptoieta and Argynnis. Owing to 

 the resemblances spoken of in the different stages, I placed Euptoieta 

 between Argynnis and Melitaea in my Catalogue (1877), instead of before 

 Argynnis as Kirby gives it, and I am of opinion that I did right.
