Diagjtostic characters. — The largest bat found in Indiana ; 

 length over five inches; forearm two inches, color grizzled gray; 

 interfemoral membrane densely furred above. 



Description. — The arrangement of the oolor bands of the hair 

 is like that of L. borealis. However, the band next to the hoary 

 tips is dark chocolate, instead of red, and the white tips are longer 

 and more numerous. On the head, the white tips are shorter and 

 the next band is yellowish brown. On the belly it is very dark and 

 the white tips are mostly absent. 



The ears are similar in form to those of the red bat. The inner 

 surface is thickly covered with short hairs except at the edge. The 

 tragus is also quite hairy on the outer side. The tragus is rather 

 more slender in proportion to its height than in L. horealis. The 

 membranes are similar to those of the preceding species and are 

 furred in the same way. 



Measurements. — A single adult female from Bloomington meais- 

 ured as follows: Total length, 130 mm. (5 3/16 in.) ; tail, 54 mm. 

 (2 2/16 in.); hind foot, 11 mm. (7/16' in.); forearm, 53 mm. 

 (2 2/16 in.) ; tibia, 23 mm. (15/16 in.) ; ear (from meatus), 17 

 mm. (11/16 in.). 



Skull and teeth. — The skull (fig. 33) and teeth resemble those 

 of L. horealis in form, but are noticeably larger. Miller gives the 

 following measurements for the skull of an adult female from Min- 

 nesota: Greatest length. 17 mm. (11/16 in.) ; zygomatic breadth, 

 12 mm. (8/16 in.) ; upper tooth row, 9 mm. (5/16 in.). 



Range. — Found throughout North America, but probably not 

 occurring in the Southern States in summer. Miller states that 

 the species does not breed south of the boreal zone. However, a 

 female with two half-grow^n young were taken in this State at 

 Bloomington in June, and C. F. Fite has taken specimens at Denver, 

 Miami County, on June 20 and 31. Other Indiana records are: 

 Lake, White, Franklin, Lawrence, Monroe, Jefferson, Wayne and 

 Wells counties.
