The Life History of a Bee-Fly {Spogosiyhmi anale Say); the Larvae Parasitic 

 on the Larvae of a Tiger Beetle Cicindela soutellaris Say. (The eggs are laid in July 

 and August; larvae on the last larval stage of the host in the spring; when the host 

 makes its pupal cell and the internal parts become semi-fluid, the parasite moults 

 and grows very rapidly completely destroying the host. (July.) The pupa digs 

 toward the surface by wriggling movements of the body, and the adult emerges when 

 the surface is reached.) (Title only.) Victor E. Shelford.

 mic value of these .organs.) Dr. E. P. Felt.

 Ephemerid line.) Dr. E. H. Sellards.
