the southern part of the state ; in most locaHties it is very common, 
but it is nearly everywhere outnumbered by Lasiiiriis borealis. I 
have seen no specimens of Lasionycteris noctizagans from north- 
ern Wisconsin. 
Lasiurus borealis (Muller). 
Red Bat. 
Lasiurus borealis is found in nearly all parts of Wisconsin ; it 
may not occur in certain sections of the northern part of the state. 
My experience has been that the red bat is our most common bat, 
and also that it is the bat most frequently seen in cities and towns. 
This species shows great color variation. 
Lasiurus cinereus (Beauvois). 
Hoary Bat. 
I have examined only four specimens of this rare bat from 
Wisconsin. There is a male in the Milwaukee Public Museum, 
collected July ii, 1903, at Janesville, Rock County. A female, 
with two live young clinging to her, was brought to me on the 
evening of July 27, 1903 ; it was found dead in a yard on the east 
side of the public park in Milton, Rock County. The young were 
over one-third grown. Measurements of the adult female were 
as follows : Total length 149.6 mm. ; tail vertebrae, 59 mm. ; hind 
foot 13.8 mm.
