Type locality. — Kicking Horse Canyon, British Columbia. 



Range. — Western part of the United States and Canada. 



The original description of telchinum was based on two males and 

 is accompanied by a figure of the male terminalia. The movable 

 finger of the male bears five dark, enlarged setae near the posterior 

 border, the upper and lower of which are long and setiform, the 

 other three short, subequal, and spinform. Female specimens from 

 California are in the United States National Museum. 



Trichopsylla (Trichopsylla) thamba (Jordan), new combination 



Ceratophyllus thambus Jordan, 1929, Novitates Zool. 35: 36, pi. 2, fig. 21. 



Type host. — Lynx sp. 



Type locality. — Red Deer, Alberta. 



Range. — Known only from Alberta. 



The original description of thamba, based on a single male, is ac- 

 companied by a drawing of part of the male genitalia. Jordan has 

 suggested that the type host is not the true host of this species. The 

 true host is probably a mouse. 



Trichopsylla (Trichopsylla) vison (Baker), new combination 



Ceratophyllus vison linker, 1904, U. S. Natl. Mus. Proc. 27: 408. 



Ceratophyllus lucidus Baker. 1904, U. S. Natl. Mus. Proc. 27: 410, pi. 20, figs.

 Megabothris vison I. Fox, 1940, Fleas of Eastern United States, p. 72, pi. 19. 



tigs. 95, 98-99. 



Type host. — Mustela vison Schreber (mink). 



Type locality. — Peterboro. N. Y. 



Range. — United States, Canada, and Alaska. 



The type host of vison is not a true host. The true hosts are squir- 

 rels. This flea has been recently redescribed and figured by I. Fox 

 (1940). The movable finger of the male has the posterior margin 

 incurved and bears two enlarged, darkened, subequal, submarginal 

 setae. 



Trichopsylla (Trichopsylla) wagneri ophidius (Jordan), new combination 

 Cenitophi/iiiis wagneri <>i)1iidii<s Jordan. 1920. Novitates Zool. 35: 36, pi. 2, fig. 20. 



Type host. — Mustela xanthogenys Gray (weasel). 



Type locality. — San Francisco, Calif. 



Range. — Known only from California. 



The name ophidius of this subspecies was suggested to Jordan by 

 the shape of the receptaculum seminis, "the organ recalling a snake." 

 The same author differentiates ophidian from the other subspecies 

 stating that the movable finger is "on the whole broader than in the 

 two previous subspecies [wagneri and sy.staltus]" and reaches "well 

 above process P of the clasper.'' The type host probably is not a true 

 host of this flea. 



Trichopsylla (Trichopsylla) wagneri systalta (Jordan), new combination 



Ceratophyllus wagneri systaltus Jordan, 1929, Novitates Zool. 35: 35, pi. 2, 

 fig. 19. 



Type host. — "Mouse." 



Type locality. — Blackfalls, Alberta.
