HOARY BAT. 
Lasiurus cinereus (Beauvois). 
Vespertilio linereus Beauv., Cat. Peale’s Mus. Phil , 1796, p. 15. (Obvious mis- 
print for cznereus.) 
Atalapha cinerea of Kennicott and various authors. 
This species, though apparently seldom abundant in the United 
States, ranges throughout North America from the Atlantic to the 
Pacific, north to Athabasca at least, and south through Mexico 
and Central and South America to Chili. It breeds in Canada and 
the northern United States, but migrates south in winter. 
The general shape 
of this bat is like that 
of the red bat, but it 
‘may be distinguished 
from that species by 
characters already des- 
ignated; namely, by ‘i 
its larger size (fore arm Fig. 11. Head and ear of hoary bat. (Allen.) 
over 2 i1n.,0r 50 mm., 
in adults), by the blackish borders of the ears (Fig. 11) and the ab- 
sence of a notch in their lower lobes, and by the distinct patch of fur 
near the base of the fore arm. 
The color varies considerably, but the following description 
applies to the few Illinois specimens that I have seen: The general 
color is a mixture of light yellowish brown, deep umber-brown, and 
white, the yellowish brown being clear and unmixed on throat, head, 
and under side of membranes, the umber-brown predominating on 
the back and on the dorsal surface of the interfemoral membrane, 
where, however, the hairs are mostly tipped with silvery white, some- 
times to so great an extent as nearly to conceal the dark tints 
beneath. The lips, chin, and cheeks are sprinkled with short 
blackish hairs. On the ventral surface white predominates on the 
belly, between which and the yellow of the throat is a band in which 
the umber-brown is more conspicuous than elsewhere on the under 
parts. There are tufts of light yellowish brown fur at the bases of
