THE FLEAS OF NORTH AMERICA 71 



A figure of the male genitalia accompanies the original description 

 of Ceratophyllus petrochelidom. 



Ceratophyllus quebecexsis I. Fox 



Ceratophyllus riparius Jordan and Rothschild, 1920, Ectoparasites 1: 71, figs. 

 67-69. 



Type host. — "Eider clown." 



Type locality. — Saint Mary's Island, Quebec. 



Range. — Known only from Quebec. 



This species is readily separated from the other Xorth American 

 species of the genus by the characters of the male and female geni- 

 talia, drawings of which accompany the original description. 



Ceratophyllus riparius Jordan and Rothschild 



Ceratophyllus riparius Jordan and Rothschild, 1920, Ectoparasites 1: 71, 

 figs. 67-69. 



Type host. — Riparia riparia riparia (L.) (bank swallow). 



Type locality. — Bay View. Milwaukee, Wis. 



Range. — United States and Canada. 



The original description of riparius is accompanied by drawings 

 of the terminalia of both sexes. The type host of this species is a 

 bird common to Xorth America, Europe, and north Africa. In the 

 Old \Yorld Riparia riparia riparia is parasitized by a flea, Cerato- 

 phyUi's styx Eothschild. which is very closely related to C. riparius, 

 differing only in the details of the terminalia. It is rather unusual 

 to find two very closely related species of ectoparasites belonging 

 to the same genus parasitizing the same host species. A redescription 

 of C. riparius is given by I. Fox (25, p. -55). 



Ceratophyllus swaxsoxi Liu 



Ceratophyllus sicansoni Liu. 1935, Ent. Soc. Amer. Ann. 28: 121. pi. 1, figs. 1-3. 



Type host. — Asio ici7sonianus (Less.) (long-eared owl). 



Type locality. — Fertile. Minn. 



Range. — Minnesota and Montana. 



Detail drawings accompany the original description of sican- 

 soni. It is a species belonging to the gallinae group, differing from 

 gallinae in having a stouter movable finger, "the exopodite [movable 

 finger] is less than three times as long as wide, whereas in gallinae 

 it is four times as long as wide.'' 



Ceratophyllls vagabuxdus (Boheman) 



Pulex vagabunda Boheman. 1865, Qfvers. af Finska Vetensk. Sue. Forhandl. 



22 : 576. pi. 35. fig. 1. 

 Ceratophyllus vagahundus Baker, 1905, U. S. Natl. Mus. Proc. 29: 152. 



Type host. — None. 



Type locality, — "Cap Todsen in Isfjorden.'" Spitsbergen. 



Range. — In Xorth America known onlv from Alaska, as reported 

 by Jellison and Kohls (37) in 1939. 



This is a large bird flea. In Alaska it was found on fledglings 

 and in the nest of the golden eagle, Aquila chrysaetos. According
