52 FAUNA OF MAYFIELD'S CAVE. 



Ceuthophilus sloanii PACKARD, Ann. Rep. Acad. Sci., v, 1873, 93; Mem. Nat. Acad. 

 Sci., IV, 1888, 71, 83 (Bradford and Little Wyandotte caves); COLLETT, Rep. Ind. 

 Geol. Surv., 1873, 305 (Connelley's, Earner's, and Donaldson's caves at Mitchell 

 (Elrod & Sloan). 



This Ceuthophilus is known from nearly every Indiana cave which 

 has been zoologically explored and from many of the Kentucky caverns. 

 I have taken it in Mayfield's, Truett's, and Donaldson's caves in Indiana 

 and in White's and Mammoth Caves in Kentucky. * 



It is much more abundant in the smaller caves than in the larger 

 ones and near the mouths of caves than farther in. For some time 

 after this species was described it was not found in any of the large 

 caves. It is especially abundant not far from the mouth of Mayfield's 

 Cave, but is rarely found more than 250 feet from the mouth and usually 

 does not occur beyond the reach of twilight. Mr. Rothrock (cf. 

 Blatchley, 1896, 199) , who owns the hotel at Wyandotte Cave, says this 

 "cave cricket" is found as far back as Monument Mountain, far within 

 the cave, but Blatchley failed to find it there. 



This shade-loving animal is not confined to caves. Blatchley tells 

 me of their occurrence in cellars and about wells and in similar situations, 

 and mentions their abundance in a cellar at the Wyandotte Cave Hotel. 

 I have specimens from under a log on the campus of Indiana University, 

 from a cellar in Bloomington, from a cellar in Switzerland County, 

 Indiana, and from beneath logs and chunks near the mouth of May- 

 field's Cave. 



C. stygius is quite common in Mayfield's Cave, especially from the 

 mouth to "19," and is occasionally seen nearly as far in as the mound. 

 It is often seen in the well-lighted portion of the cave from the door to 

 " 4, " but is more common from?' '4" to "7" and at times is most abundant 

 from "7" to "12," where the cave is absolutely dark. Beyond "19," 

 where the first dry portion of the cave begins, it rarely occurs and only 

 in the damper places. Small individuals are often found under debris 

 on the floor, but this locustid is most common on overhanging slopes of 

 the wall and on the roof of the cave. It is perhaps most common and 

 abundant on the walls quite near the roof. It occurs abundantly also 

 in crevices of the rock, often where they are so narrow that they barely 

 admit the body. It congregates to some extent where there is an over- 

 hanging slope near the floor. 



It is not readily disturbed by light or by an object moving near, but 

 when touched springs from the surface to which it is clinging and 

 when it lands on the floor rapidly leaps away faster than one can follow 



*It has not, I think, heretofore been recorded from Mammoth Cave. I found it 

 at the end of Bat Avenue near the top of the Mammoth Dome.
