entitled to a place in a Wisconsin list (J. c., p. 31), an opinion with 
which, in so far as the record in question is concerned, I most heartily 
concur. 
Like others of our Bats it is strictly insectivorous. It frequents 
caves when available during the winter. The number of young varies 
from one to three. Hahn says, ‘‘mating takes place about the end of 
November and the young are probably born in July. The single 
pregnant female which I have examined contained three very small 
embryos on the 6th of June”’ (/. c., p. 630).
