avoid danger. A female Calidryas SenncB was struck at 

 by the writer with a net as it was passing on the wing. 

 It dodged the net, but at once turned from its course and 

 flew to a small oak-bush, where it settled, in an attitude 

 of repose, on the under side of a leaf, from which it was 

 taken by the hand. 



Some species hibernate in the butterfly, or imago, state, 

 as Vanessa Antiopa and some of the Graptas. If a chip 

 is cut from a tree in the forest so that the sap flows a 

 little, these butterflies may be seen late in the fall, when- 

 ever the weather is mild, sipping at such a place. As it 

 becomes cooler they retire to some sheltered place, where 

 they anchor themselves by the hooks in their feet and 

 become lethargic, remaining there till the warmth of 

 spring arouses them from their slumbers. The wounded 

 trees, fresh-cut stumps, and early flowers furnish them 

 the food their system demands in the spring; and in 

 due time the eggs are deposited for the new generation.
