Several specimens from Austin, Texas, May; taken from a 
lizard, Sceloporus floridanus. I have figured this species on 
page 22 of my "Treatise on Acarina." It differs much from 
the other species of the genus in general appearance, but the 
essential characters, especially the nature of the mandibles, 
are the same.

Specimens from Marblehead, Mass. (M. J. J. Gregory)
