Family Pulicidae Stephens 21 



Sweden. ("Habitat in hominibus, praesertim feminis, autumno 

 vulgaris; in nidis hirundinum ripariarum copiosissima. In 

 Lapponia non vidi.") Location of type not ascertained. 



Although Pulex irritans probably occurs in every state of the 

 Union, it is seldom found in large cities and is doubtless absent 

 from many forested and swamp areas. Man, dogs, and hogs 

 seem to be its most favored hosts.
