Family PULIOIDiE. 



PULEX Linn. 



P. irritans Linn. The common house flea. 



P. howardi Baker. Found on mice and squirrels, from New York to Georgia 



and west to Nebraska. 

 P. serraticeps Gervais. This is the common cat and dog flea which occurs 

 everywhere. 

 There are undoubtedly many other species occurring on rats, mice, bats, 

 rabbits, &c, but no collections have been made : the order is not so well repre- 

 sented with us, however, as it is in warmer countries.
