Wagner (80, p. 14) lists two additional synonyms which have been 

 used by European authors. 



Ceratophyllus gilvus Jordan and Rothschild 



Ceratophyllus gilvus Jordan and Rothschild, 1922, Ectoparasites 1: 270, 

 figs. 264-265. 



Type host.— "Swallow." 



Type locality. — "Facubaya," Mexico. 



Range. — Known only from Mexico. 



The original description of gilvm, based on a single specimen of 

 each sex, is accompanied by drawings of the terminalia. The species 

 is a small, pale one, said to be "similar to C. rusticus Wagn." 



Ceratophyllus idius Jordan and Rothschild 



Ceratophyllus idius Jordan and Rothschild, 1920, Ectoparasites 1 : 73, figs. 70-72 ; 

 I. Fox, 1940, Fleas of Eastern United States, p. 51, pi. 12, figs. 60-61. 



Type host. — Iridoprocne bicolor (Vieill.) (tree swallow). 



Type locality. — Okanagan Landing, British Columbia. 



Range. — United States and Canada. 



The original description of this common swallow flea is accom- 

 panied by drawings of the terminalia of both sexes. An important 

 feature of the species is that the upper half of the movable finger 

 is strongly rounded. 



Ceratophyllus Niger C. Fox 



Ceratophyllus niger C. Fox, 1908, Ent. News 19 : 434. 



Ceratophyllus niger inflexus Jordan, 1929, Novitates Zool. 35: 37, pi. 2, 

 fig. 25. 



Cotype hosts. — Man and Rattus norvegicus (Erx.) (house rat). 



Type locality. — Not indicated. 



Range. — Western and northern parts of the United States, Canada, 

 and Alaska. 



Wagner (84, pp. 200-201), in 1936, stated that he found "typical O. 

 niger as well as C. nig. inflexus" from "one and the same hen house" 

 in British Columbia, hence concluded that inflexus has no valid status 

 as a distinct variety. 



Ceratophyllus niger is a species of some economic importance, being 

 a serious pest of hen houses in parts of western North America. 

 Control measures for this flea (under the name of Pulex avium) as a 

 hen-house pest have been published by Ewing (14)- It readily 

 attacks man. 



Figures of the terminalia are given by I. Fox [25, p. 155). 



Ceratophyllus petrochelidoni Wagner 



Ceratophyllus petrochelidoni Wagner, 1936, Ztschr. f. Parasitenk. 8: 655, 

 fig. 2. 



Type host. — Petrochelidon albifrons albifrons (Raf.) (a cliff 

 swallow). 



Type locality. — Chilcotin, British Columbia. 

 Range. — British Columbia.
