As the solitary wasps are too few in numbers to do much 

 damage — even if they ever do any — any great damage which

 (Pyrosoma bigeminum) that causes the terrible Texas fever, is

One spring a lady bee-keeper of Connecticut discovered

 of their rapid depletion. She had noticed that the colonies 

 were greatly reduced in number of bees, and upon close obser- 

 vation she found that the diseased or failing colonies were
