680 KANSAS CITY REVIEW OF SCIENCE. 



turbed when gathered in a cluster about a piece of meat, they scattered in every 

 direction over the sand, so that it was difficult to pick them up rapidly. I found 

 the best method to be to throw the lump with Adelops clinging to it on to a hand- 

 kerchief. The beetles then hid in the folds of the cloth, and could be picked up 

 by a quill passed through the cork of the collecting bottle. In this way we se- 

 cured several hundred specimens in a few minutes. To secure a good supply of 

 larvse, it was sufficient to tie up in a cloth one or two small fragments of chicken 

 bone crowded with insects. These, unfortunately, remained forgotten in my col- 

 lecting sack until after my return home, a week later, when I found and exam- 

 ined them. They were much crushed, and the larvae all dead, but, of the twenty 

 or more Adelops which adhered to the lumps, and had been imprisoned with 

 them, two were still alive. Both, however, died after another week's confine- 

 ment. Some of the puparia of the fly were also uninjured, and in a few days 

 several perfect Phoras made their appearance from them. Three or four living 

 mites (Acarus), and a very minute Psocid (Atropos divinatoria Muell.), possessing 

 eye-spots and undeveloped wings, were also found upon the lumps. Washing- 

 ton's Hall was said to be a good locality for Anophthalmus, but we found only a 

 few specimens under flat pieces of gypsum. 



The party of sight-seers had, in the meantime, gone to the end of the cave, 

 and a few minutes before their return "Pete," who had remained with us, pro- 

 posed to take us to a place where plenty., of Anophthalmi could be found. He 

 then led us back a short distance to a passage called Martha's Vineyard. Here 

 the rocks are damp, with some dripping springs, and one quite large pool known 

 as Hebe's Spring. This locality did not disappoint our expectations. It is 

 one of the best in the cave ; but, as we had but a few minutes' time, we were 

 obliged to hurry over the ground and could delay but a few moments in one 

 place. The guide, constantly moving on, called back to us that it was dangerous 

 to fall behind. At Hebe's Spring, the repairing of a stairway left the timbers of 

 the former structure scattered about, and under these, Anophthalmus Tellkampfii 

 and A. Menctriessii were common, the former much more abundant than the lat- 

 ter, however. I found here, under a piece of wood lying on sand, a specimen of 

 a larva which agrees perfectly with Packard's figure of that of A. Tellka?npfii* i 

 We also secured two specimens of Phrixis longipes, the blind Phalangid spider, or 

 Harvestman, described by Cope.f 



With a little more time at our disposal, I feel sure that the pupa of Anoph- 

 thalmus would have been found at this spring, as many of the imagos taken were 

 quite fresh. The pupa has, however, already been figured by Packard in his paper 

 on the beetles of the cave. While I devoted myself to hunting under boards and 

 stones for other insects, taking only an occasional specimen of Anophthalmus, 

 "Pete" and N. were capturing numbers of the latter, all of them resting in exposed 

 places upon the side-walls, where it was quite damp, and usually several feet from 

 the floor. They were not at all difficult to find or to capture, and we took about thirty
