Phryganides comes front the little worm Phryganium (whichin English is called Cados worm) living in the waters, and in the midst of August ascending to the top of superficies of the waters ; it hath four wings of a brown colour, the body somewhat long, having two short horns, the tail forked, or rather bristles coming out of the tail.
