ribs, each terminating at a small circle at the apex, in the <:enter of 

 which the germ could be distinctly seen. The instinct of the butter- 

 fly in selecting the dwarf willows, which develop earliest, as a deposi- 

 tory for its eggs in spring, while preferring the tree willows for the 

 August brood is a matter of common experience. Last summer a 

 large brood of the larvae of this insect fed on the hop vines in the rear 

 of my Brooklyn residence. A comparison of the number of eggs laid 

 in the present instance with the ordinary number of larvK generally 

 constituting a brood after the second or third adult (50-100) may be 

 used as an indication of the great percentage which never attain ma- 

 turity. The stalk with its egg cluster were preserved in order to note 

 further developments.
