ipo MR. RICHARD S. HAGNALL ON THE SIPHONAPTERA 



Ischnopsyllus iiiteniiedhis Roths. (1S98). 



" A rare species, probably confined to the serotine bat 

 {Eplesicus serotinus). Only recorded from England, not from 

 Scotland or Ireland." 



Ischnopsyllus hexacteniis Kolen. (1856). 



Has occurred in Yorkshire on the long-eared and 

 Natterer's bats. " A common species in England and Ireland, 

 but not recorded from Scotland. The chief host is the long- 

 eared bat {Plfcofus auritus), but specimens have been found 

 on other species of bats." 



Nycteridopsylla longiceps Roths. (1908). 



"An uncommon species, unrecorded from Scotland or 

 Ireland. Specimens have been taken from the pipistrelle 

 {Pipistrellus pipistrellus), and the long-eAred bat {Plecotus 

 auritus), in several localities in England." 



Nycteridopsylla eusarca ///dr/'f/' Roths. (1908). 



" A rare species not recorded from Scotland or Ireland. 

 Has been found at Cambridge, and at Yalding in Kent on 

 the noctule {Nye talus noctula)^ 



Two European species, N'. pentactenus Kolen., and /. 

 nnipectinata Tasch., the latter of which occurs commonly on 

 the Continent on the horse-shoe bats {Rhinolophus\ have not 

 yet been found in the British Islands, whilst it is almost certain 

 that an examination of the rarer species of British bats would 

 add to our known flea fauna.
