REPORT OF STATE GEOLOGIST. 



Habits. — Like Lasiurus horealis, the present species is chiefly an 

 inhabitant of the forest, and migrates southward in winter. It has 

 never been reported as living in the caves, but two skulls were found 

 in the Shawnee Cave at ]\Titchell, along with those of the red bat 

 previously mentioned. 



Little is known of the peculiarities of its breeding or feeding 

 habits. In southern Indiana the young are apparently born early 

 in June. Dr. A. M. Banta took a female with two young in June;

they are preserved in the collections of Indiana University. The 

 young were still clinging to the mother, but are two-thirds grown. 

 They measure 110 mm. in total length ; forearm, 45 mm. The fam- 

 ily were chased out of a tree by a robin and fell to the ground in 

 front of the zoological laboratories of Indiana University. 



This species does not fly until late in the evening, when it is not 

 easily distinguished, and this fact doubtless accounts for the small 

 number of records. It can be rec()gniz(Ml 1)\' its large size, swift 

 flight and pointed, hawk-like wings.
