 Plains (Jn), Palisades, VII, 26 (Love) : this is the "drone" or "chrys- 

 anthemum fly " which occurs throughout the State- It is said to pollen- 

 ize chrysanthemums, and to be the only insect engaged in this laudable 

 occupation. It also resembles a honey bee so closely that most persons 

 decline to handle it. Therefore it is called " drone-fly." Its larva lives
