1916] Ferris — Nofes on Anoplura and Mallophaga 99 



Trichodectes quadraticeps Chapman. 



Several specimens from a skin of Vulpes cascadensis (Mt. 

 Shasta. CaHf.). 



This species has previously been recorded only from Urocyon 

 californicus and there has been no record of any Mallophagan 

 from a North American species of Vulpes although a species, 

 Trichodectes imlpis, has been recorded from a European Vulpes. 

 It is possible that these two species will prove to be the same. 



Trichodectes mephitidis Osborn. 



Many specimens from Bassariscus astutus raptor (Pleasant Val- 

 ley, Mariposa Co., Calif.) and from skins of the same host from 

 several other localities in California. The occurrence of T. meph- 

 itidis upon this host seems rather anomalous as this species is 

 typically mustelid-infesting; however, it seems to be normally 

 present upon Bassariscus as well. Another species, T. thoracicus 

 Osborn, has also been described from the same host. 



Trichodectes geomydis Osborn. 



From Thomomys monticola (Yosemite National Park, Calif.) and 

 skins of Geomys cumherlandius (Cumberland Is., Ga.). 



Anoplura. 

 Polyplax spinulosa Burm. 

 From Microtus {Lagurus) intermedius (Pine Forest Mts., Nev.). 



Polyplax auricularis Kellogg & Ferris. 



From Peromyscus maniculatus gambeJi (Yosemite National Park, 

 Calif.) and skins of Onychomys torridus pulcher (Victorville, Calif.) 

 and Onychomys leucogaster arcticeps (Colorado Springs, Colo.). 

 Previously recorded from Peromyscus maniculatus rnbidus (In- 

 verness, Marin Co., Calif.) and Peromyscus sitchensis prevostensis, 

 (Forrester Is., Alaska). 



Host of the type, Peromyscus maniculatus rubidus. 



Linognathoides montanus Osborn. 



From M armota jiaviventris sierroe and Citellus beldingi (Yosemite 

 National Park, Calif.) and skins of Cynomys leucurus (Routt Co., 

 Colo.), Citellus oregonus (Pine Forest Mts., Nev.), Citellus gram-
