 Wheeler, who identified the species. The mild winter was un- 

 usually favorable for the hibernation of southern insects, such as 

 the corn ear worm. It also affected the development of plant life 

 and as a consequence many trees and shrubs budded extremely 

 early. American elms were in bloom at Nassau on March 27th, 

 and Carolina poplar catkins were falling in considerable numbers 

 April 6th. Apple leaves were about half an inch long and pear
