Distribution. Found almost throughout the temperate Pah"earctic 

 region and widely spread in the Ethiopian. This bat has been 

 found in Nepal and 8ikhim, and perhaps in Kandahar; there are 

 specimens in the British Museum labelled Ceylon and Singapore, 

 and the species has been recorded from Sumatra and Java. 



Habits. The noctule bat generally rests in trees during the day, 

 though it is sometimes found in considerable numbers in buildings. 

 It appears early in the evening, and has an especially strong and 

 powerful flight, rising high in the air. It haunts wooded country, 

 and lives largely on cockchafers and similar beetles. It hibernates 

 thoroughly, never appearing till late in the spring, and it disappears 

 soon in the autumn. liarge numbers are found hibernatiiag 

 together. This species has a strong unpleasant odour, A good 

 account of some of its habits, and especially of the birth of the 

 young, by Mr. Gr. Daniell, will be found in the Pro©. Zool. Soc. for 

 1834, p, 130. He found only a single young in several females ; 

 but Blasius states that t\Ao are geiierally produced. The young 

 are born blind and naked.
