THE CANADIAN ENTOMOLOGIST. 35 



Bellona, in all its preparatory stages, is closely like myrina. The egg 

 is of the same pattern, but rather longer, and the sides are less rounded ; 

 the larvae in first stages can scarcely be distinguished ; in the last the 

 spines of second segment are not lengthened as in viyyina. 



Atlantis was abundant, but the females set on violet laid no eggs, and 

 I found on dissection that their eggs were yet immature. On 24th Aug. I 

 took a pair of atlantis in copulation. It was in the forest, five miles from 

 home, and I tied the pair in my net and suspended it on a tree. The 

 next day, on returning, I found the pair separated, and brought the female 

 home and set on violet. Two days after, 28th, there appeared to be but 

 a single egg laid. The next day I discovered another, and by the 31st 

 she had laid about a dozen, and I compassionated her endeavors and let 

 her fly away. I kept all these butterflies alive on sugar and apple. The 

 eggs hatched in 17 or 18 days. At the same time, I obtained a large 

 number of eggs from other atlantis, which duly hatched. All the larvae 

 forthwith began their sleep, as do those of cyhele and aphrodite, diana and 

 idalia, and that on empty stomachs, for as a rule they eat nothing. 



And inasmuch as atlantis deposited eggs but a few days after copula- 

 tion, and myi'ina does almost immediately after, we get light on an early 

 brood of cyhele, &c. For Mr. C. G. Siewers, of Newport, Kentucky, wrote 

 me last summer that he had taken two pairs ' of t^/^^Zf in copulation, in 

 July. I think it probable, therefore, that these large species are digon- 

 eutic in \\'est Va. and the Ohio Valley. The early brood of cybele 

 (butterflies) appears in great force here by ist June, on the clover blos- 

 soms, first the males, and in a few days the females. After the 15th to 

 20th June, they disappear, and in July I scarcely ever see an example. 

 By 15th August fresh males appear again, and soon after fresh females, and 

 I can always obtain eggs between ist and 20th Sept. Just so with aphro- 

 dite. I should not have doubted there being two broods were it not for 

 the fact that the several stages of the larvae which feed in spring are so 

 remarkably prolonged that it seemed unlikely that between 15th June and 

 .t5th Aug. the several stages of t^gg, larv^a and chrysalis could be passed ; 

 and furthermore, that I had repeatedly dissected females q{ cybele in June, 

 and when I could obtain them, in. July and first half of August, and never 

 yet found the least appearance of a formed egg. Nothing but fatty masses 

 to represent them. But suddenly, about the middle of August, the eggs 

 begin to take shape, and in a week or ten days are ready to be laid. But 

 the hot weather of July and August, the mercury constantly running
