In the December number of the 'Entomologist' for 1908, 

 p. 281, we described a new species of five-combed bat-flea under 

 the name of Nycteridojpsylla longiceps, comparing it with another 

 British species which we identified at that time as pentactejius, 

 Kolenati. Oar identification was based on specimens from 

 Kolenati's collection preserved in the Vienna Museum, with 

 which the British ones agree fairly well. This identification has 

 now proved to be erroneous, and we think therefore that a 

 general survey of all the known species of the genus Nycteri- 

 dopsylla may be attempted with advantage.

Kolenati originally described two species in ' Die Parasiten 

 der Chiropteren ' under the names of pentactenus and tetractenus, 

 which he subsequently united under the latter name in the 

 ' Horse Societatis Entomologicae EossicaB.' The description and 

 figure are insufiicient, but two characters are mentioned which 

 refer to this species only. In the ' Parasiten der Chiropteren ' 

 Kolenati states, under pentactenus, that the second segment of
