N. Y. Three additional female paratypes were collected by F. O. 

 Dodd at Xew York, March 1, 1935, when intercepted in quarantine 

 in valones (nuts) originating in Turkey. 



This species is similar to Cheyletus hendersoni^ new species, but 

 differs in having the anterior tooth on the palpal claw smaller, in the 

 relative sizes of the palpal comb and number of teeth, in the shape of 

 the dorsal shields, and in the relative lengths of tarsus I guard setae 

 to the sensory setae.
