The only life found in the cave was a beetle, identified by Dr. Horn as DicUdia Icetula Le Conte, two flies, and three Coleopterous larvae. The beetle occurred near the entrance, and did not differ materially from other speci- mens which I collected under stones in the caiionnear the entrance to the cave. A species of Mycetophilid fly also occurred near the door, as well as a specimen of Blepharoptera defessa, Osten Sacken,* not differing from specimens which occur in various caves in Indiana (Wyan- -DicUdiaicetuia^naiaTxa. clottc), Mammoth Cavc, and adjoining ^Blepharoptera defessa,n. sp., d" ?.—A sparse pubescence on the under side of the pleurae, a single vibrissa on each side of the epistoma, a single strong bristle above the middle tibi£e; costa beset with moderately long bristles; length 5-6'^^™. Antennte red, third joint brownish red ; arista rather long; front yellowish-red; frontal orbits grayish; a paler triangle on the vertex, bearing the brownish ocellar tubercle ; anterior frontal bristle short, the one behind not quite twice as long. Thoracic dorsum yellowish-gray ; the eight large dorsal bristles are inserted on brown spots, which are sometimes confluent; the finer pubes- cence on very minute dark spots, an often faint brown stripe in the middle, and a still less distinct one on each side ; hume- ral callosities reddish, the flat scutellum likewise. Pleurte pale brownish-gray, darker below. Abdomen grayish-polli- nose, the ground color being blackish; male hypopygium yellow, with delicate black pile; tip of the female abdomen also yellowish; hind ma
