Tliis species is almost identical witli Pergaiule's figure of Eremaeus pilosus 

 ill Hank's "Treatise." My speeinieiis lack the simple bristle on the apex of the 

 penultimate joints of tlie legs, and the body is slightly broader. Michael's key 

 places this species as a Xotaspis, close to X. xerrata. The species E. pilosus 

 is referred to by Banks in his Catalogue to his description of Scutoverlex pilosus

in Trans. Amer. Ent. Soc. XXII, p. 11, which as Michael remarks is "appar- 

 ently not a Scutovertex, probably a Xotaspis (said to be so by Banks, in litera)." 

 I also present the following illustrations of mites which I have identified as : 



Phthiracarus retalticus (Stoll) 



(Figure 241) 



This species was described from Guatemala. My specimens were found 

 under drift-wood on salt marsh, Pawson Park, Conn., during August. The length 

 of my specimens (from tij) of abdomen to dorsal suture) is 685 niicrm.
