If I may snggest the conclusion to which my present 

 limited array of facts points, it is that a few females are the 

 first to appear, that about the middle of the flight the num- 

 bers of the sexes are equalized, and that the males continue 

 to appear for a day or two after all the females have emerged 

 from the pupa ; and this appears to be an arrangement ad- 

 mirably calculated to provide a partner for every female. 

 From various causes female moths appear to be less nume- 

 rous than males, but 1 believe this to be only in appearance: 

 the female has more important business in hand than sipping 

 sugar or flying round a lamp, and is also more lethargic in 

 her habits 1 have been struck with the equal division of 

 the sexes in broods reared from the egg; for instance, in the 

 large brood of L. caniola reared this year, the number of 

 each sex is exactly the same ; whereas at large I have never 

 captured more than one female for ten males of this species.

 my request, kept a daily record of his captures, resulting in
