THE FLEAS OF NORTH AMERICA 33 



Orchopeas caedens (Jordan) 



Ccratophi/Uus caedens Jordan, 1925, Novitates Zool. 32: 104, figs. 16 and 17. 

 Ceratophi/Uus caedens durus Jordan, 1929, Novitates Zool. 35: pi. 1, fig. 3. 

 Orchopeas caedens Jordan, 1933, Novitates Zool. 39: 71. 



Type host. — Maries americana (Turt.) (marten). 



Type locality. — Banff, Alberta. 



Range. — United States, Canada, and Alaska. 



The writers are following Wagner (84, P- 109) in the synonymy 

 given above. Under the name of Ceratophyllm caedens durus Jor- 

 dan, this species was reported from south Labrador by Eidmann (13, 

 p. 100), the specimens having been determined by Jordan. 



Orchopeas dieteri (C. Fox) 



Ceratophyllus nepos dieteri C. Fox, 1929, Ent. News 40: 218. 



Orchopeas dieteri I. Fox, 1940, Wash. Ent. Soc. Proc. 42: 66, pi. 10, figs. 5 and 6. 



Type host. — Lynx rufus (Schreber) (bobcat). 

 Type locality. — Los Angeles County, Calif. 

 Range. — Known only from California. 



I. Fox (1940) redescribed dieteri as a species and gave drawings 

 of the parts of the terminalia of both sexes. 



Orchopeas howardii (Baker), new combination 



Pulex howardii Baker, 1895, Canad. Ent. 27: 110. 



Pulex wickhami Baker, 18!)."), Canad. Ent. 27: 109; I. Fox, 1940, Fleas of Eastern 



United States, p. 59, pi. 15, figs. 75-77. 

 Pulex giUettei Baker, 1895, Canad. Ent. 27: 109. 



Cotype hosts. — "Squirrel," "gray or fox squirrel," "nest of field 

 mouse." 



Cotype localities.— Ithaca, X. Y.; Tallulah Falls, Ga.; Lincoln, 

 Xebr. 



Range. — United States east of the Great Plains. 



The name wickhami has long been used for this species and has 

 page precedence over howardii. However, Baker (3. p. 37) in 1899 

 selected howardii for the name of the species. He states: 



Pulex howardii Baker. In the group which includes this flea and fasciatus 

 and its allies, the males determine the species. For this reason wickhami and 

 giUettei are not well founded. They were separated on characters whose values 

 could not have been correctly estimated at the time. They should be reduced to 

 synonyms of howardii. 



The life history of this flea (under the name of wickhami) has been 

 studied by Sikes (70), who gives a description of the eggs and first 

 three larval instars. 



A chalcidoid parasite, reared from a larva of howardii, was de- 

 scribed by Waterston (89) under the name of Boiramlia fusdpes. 

 Parasites of this type are very rarely reported from ectoparasites. 



Orchopeas labiatus (Baker) 



Ceratophyllus labiatus Baker. 1904, U. S. Natl. Mus. Proc. 27: 402, pi. 19, 



figs. 6-9. 

 Orchopeas labiatus Jordan, 1933, Novitates Zool. 39: 72. 



Type host. — Lynx canadensis Kerr (Canada lynx). 

 Type locality. — Moscow, Idaho.
