FOXELLA WAGNER 

 Foxella Wagner, 1930, Konowia, 8: 314. 



Genotype: Pulex ignotus Baker 



Eye rudimentary. Ocular row consisting of four to six 

 bristles, the ocular bristle situated well above the eye rudi- 

 ments. Pronotal ctenidium consisting of ten or eleven spines 

 on a side. Females with three antepygidial bristles on a side, of 

 which the middle is the longest and the uppermost the shortest. 

 Males with one long and one short antepygidial bristle on a side. 

 Other details essentially as in Ceratophyllus Curtis. 



This genus is represented in the East by a single species 

 whose favorite host seems to be the pocket gopher. So far it 

 has not been found further east than Illinois.
