INSECTS OF THE CAVE. 



Fig. 124. 



Anoptlialmus Tellkampjli of Erichson, a Carabid (Fig. 124), and 

 Adelops hirtus Tellkampf (Fig. 125) allied to Catops, one of the 

 Silphidse or burying beetle family. The Anoptlialmus is of a pale 

 reddish horn color, and is totally blind ; * in the Adelops, which 

 is grayish brown, there are two pale spots, which may be rudi- 

 mentary eyes, as Tellkampf and Erichson suggest. No Hemip- 

 tera (bugs) have yet been found either in the caves of this coun- 

 try or Europe. Two wingless grasshoppers (generally called 

 crickets) like the common species found under stones (CeutJio- 

 philus maculatus Harris) , have been found in our caves ; one is 

 the Hadenoecus subterraneus (Fig. 126 nat. size) described by Mr. 

 Scudder, and very abundant in Mammoth Cave. The other spe- 

 cies is C. stygia Scudder, from Hickman's 

 cave, near Hickman's land- Fig. 123. 

 ing, upon the Kentucky river. 

 It is closely allied to the 

 Mammoth Cave species. Ac- 

 cording to Mr. Scudder, the 

 specimens of C. stygia were 

 found by Mr. A. Hyatt " in 

 the remotest corner of Hickman's Cave, 

 in a sort of a hollow in the rock, not par- 

 ticularly moist, but having only 

 a sort of cave dampness. They 

 were found a few hundred feet 

 from the sunlight, living exclu- 

 sively upon the walls." Even 

 the remotest part of that cave is 

 not so gloomy but that some 

 sunlight penetrates it. 

 The other species is found both in Mammoth Cave, and in the 

 adjoining White's Cave. It is found throughout the cave, and 

 most commonly (to quote Mr. Scudder) "about 'Martha's Vine- 

 yard' and in the neighborhood of 'Richardson's Spring' where 

 they were discovered jumping about with the greatest alacrity 

 upon the walls, where only they are found, and even when dis- 



*In Erhardt's cave, Montgomery Co., Virginia, Prof. Cope found "four or five spec- 

 imens of a new Anoptlialmus, the A. pusio of Horn, at a distance of not more than three 

 hundred feet from its mouth. The species is small, and all were found together under 

 a stone. Their movements were slow, in considerable contrast to the activity of ordi- 

 nary Carabidze." Proc. Amer. Phil. Soc. 1869. p. 178.
