POLYGAMY OF ACTl.VS LLNA AND 

 CALLOSAMIA PROMETHEA. 



On April 29th, 1S94. a $ and ? A. lima 

 emerged in mv hox, and on that night mated, 

 remaining in coitti until after ten o'clock the 

 next day. On April 30th, the $ was put 

 into a box prepared for egg-haying, and a 

 newly emerged $ was put into the cage with 

 the $■ That night, between ten and eleven 

 they were found in coitii, and so remained 

 until after ten o'clock the next day. Both 

 females laid many eggs, and both sets of eggs 

 gave larvae on Ma^' 21st and 22nd. The $ 

 was kept for several days, but, as no other ? 



emerged, was then let out at the window and 

 flew away alniost as vigorously as a freshly 

 emerged moth. 



In 1893 a ? C. prometltcti, in a cage by an 

 open window, attracted about forty $$ 

 twenty of which were caught and put into the 

 cage. At first they all flew up and down the 

 netting, with great excitement and mucli 

 vibration of tlie wings, then six of them seized 

 the abdomen of the ? with their claspers, 

 and struggletl for possession, nor did the 

 others lose their hold when one was success- 

 ful. After fifteen minutes this $ was re- 

 moved and put into another cage, when a 

 second took his place almost immediately, 

 and was left for twenty minutes, tlien was 

 removed and put into the second cage. In 

 less than ten minutes a third $ had mated 

 with the $, was later removed, and a fourth 

 took his place. This was repeated until 

 seven $ $ had mated witli this one $. 



Meanwhile these $$ not caiiglit were 

 living up and down the outside of the cage 

 and finally dropped dead with exertion and 

 excitement. They were kept two days to be 

 sure that they would not revive. 



So many $$ were flying about the win- 

 dow that three cats spent an hour or more 

 trving to catch them, and passers-by stopped 

 to look. 



When the seventh J had been mated I'or 

 :in hour he was removed, and the ? taken 

 outdoors and put on a low branch of an ash 

 tree. There she attracted all the unmated 

 (J (J and an eighth paired with her. The 

 others flew about the tree, until dark, when 

 observations ceased. 



Eggs laid by tliis J hatched in due time. 



As all accounts of -'attraction" which I 

 have seen state that when the $ is mated the 

 $ $ V^y "° further attention to her, it seems 

 worth while to ofl^er this experience, which 

 was a surprise also. Caroline G. Soiile.
