To solve many other questions it would be of the greatest 

 importance that we should be able to examine more indivi- 

 duals of this interesting family. Collectors and scientists who 

 have an opportunity to examine bats in the countries where P0I3'- 

 ctenidcC can be found (vSouth Asia and tropical America) ma}' be 

 ])ra3'ed to pa}' attention to these ectoparasitic insects as well as 

 others on the bats ; for the Nycteribiida? certainly contain within 

 their family many questions also to be solved. Whatever is 

 collected must be preserved in alcohol, for only in specimens so 

 prepared can the stages of metamorphosis contained within the 

 skin be seen and examined.
