Genus Euphthiracarus^" n. ^en. 



With the characters of the subfamily Hoplodermatinae. Ungues 

 tridactyle; anal and genital covers fused. Integument rough, pitted or 

 sculptured. (See Fig. (i). 



Type species: E. jiavus (Ewing).

This genus is suggested for the rough or pitted species of the 

 old genus Phthiracariis. In this country I know of only one 

 such species, the type. We have, however, about a dozen 

 described species of the old genus Phthiracariis. 



Acknowledgment. 



Dr. J. W. Folsom, of the University of Illinois, aided the 

 writer very materially in the preparation of this synopsis by 

 offering him a laboratory in which to work and by helping 

 secure some of the much needed literature.
