Plate XYI. 
Fig. 1. Lipura ? lueifugus Pack., Wyandotte Cave. Emerton del. 
Fig. 2. Degeeria cavernarum, Pack., from Little Wyandotte Cave.—c, collophore: 2 g, antenna of an example from 
Carter caves (Zwingle’s) ; 26, elater or spring of a Little Wyandotte specimen; 2c, antenna of a Bradford 
* Cave specimen; 2d, antenna of a Diamond Cave specimen; 2c, elater of a Bradford Cave example; 2/> 
elater of a Diamond Cave example; 2 g, 2 g', elater of an individual from Carter Caves (Zwingle’s); 2 a, end 
of tarsus of leg of the second pair. 
Fig. 3. Lepidocyrtws atropurpureus Pack., from Diamond Cave.—3a, end of one of the last pair of legs; 36, end of 
the elater. 
Fig. 4. Smynthnrus ferrugineus Pack., . 08 mm long, from Weyer’s Cave.-— 4a, antennae ; 46, end of one of the legs of the 
third pair ; 4c, elater. 
Figs. 2 to 4, and details, drawn hy the author with the camera lucida. 
Plate XYII. 
Fig. 1. Campodea coolcei Pack., enlarged.—la, head, upper side ; 16, the same, under side ; lc, terminal joints of the 
antennae, showing at (of.) the olfactory (?) area ; Id, Id', antenna; If, 1/', If", one of the cercopods ; 1 g, 
end of the body, with a portion of a cercopod ; 16, end of the body ; li, spinulated setae on different parts 
of the body. 
Fig. 2. Campodea staphylinus Westw.—Terminal joint of the antenna, showing the olfactory (?) area. 
Fig. 3. Sadenceeus subterraneus, Mammoth Cave. Fungus (/.) growing from the end of the body. Kingsley del. 
Fig. 4. Dorypteryx pallida Aaron.—Eight maxilla from above ; 4a, the same enlarged; 46, end of a claw. Drawn hy 
Dr. Hagen. 
All the figures, except 1, la, 16, 3, and 4, drawn hy the author. 
Plate XYIII. 
Fig. 1. Anophthalmus tellkampfii Erichs. (Emerton del.)—“ The figure is a poor one ; the antennae, head, and thorax, 
and on the elytra the characteristic pair of sensitive hairs is entirely omitted; all other species have three 
sensitive hairs on each elytrum ” (E. A. Schwarz in letter). 
Fig. 2. Anophthalmns tenuis Horn 
Fig. 3. Anophthalmns eremita Horn, Little Wyandotte Cave.—“ A tolerably fair representation ; the last joint of the 
maxillary palpi should he longer than the penultimate, and some indication of the elytral stri® ought to he 
given” (Schwarz). 
FiG. 4. Anophthalmns menetriesii Motsch. (Emerton del.)—“ This is a fair representation, except that the antennas aro 
altogether too heavy” (E. A. Schwarz). 
Fig. 5. Anillus explanatus Horn, (copied from Horn).—The antenna) darwn hy lithographer too stout and the set® 
too coarse. 
Plate XIX. 
Fi-g. 1. Anophthalmns teWcampfii Erichs., from Salt Cave.—Antenna; la', three olfactory set® and two tactile set® from 
the third segment from the end of the antenna; 16, terminal joint of left antenna of example from Mam¬ 
moth Cave ; lc, left maxilla of example from Salt Cave ; lc', end of left maxillary palpus ; lc”, end of left ■ 
galea ; Id, labium of Salt Cave example; le, end of a fore leg from a Mammoth Cave example. 
Fig. 2. Anophthalmns menetriesii Motsch., from Diamond Cave.—Antenna; 2a, terminal joint; 26, end of right maxil¬ 
lary palpus; 2c, end of left galea; 2d, labial palpus; 2e, end of a leg of the first pair. 
Fig. 3. Anophthalmns tenuis Horn, from Bradford’s Cave.—Antenna; 3a, terminal joint of the antenna; 3a',fourth 
joint from the end, showing the arrangement of the olfactory set®; 3a”,four of the same in the middle of 
the joint; 3a'", a number of olfactory set® crowded together on the middle of the terminal joint of the 
antenna (they also occur in the same crowded condition on the penultimate joint, the third being much as 
the fourth joint from the end, hut the set® no more numerous) ; 36, end of maxillary palpus; 3c, end of left 
galea; 3d, a leg of the first pair; 3e, end of the same, enlarged. 
Fig. 4. Adelops hirtus Tellkf. Antenna, much enlarged, showing the olfactory organs (oh) on the last four joints; 4a, a 
maxillary palpus. 
All thefigures drawn by the author with the camera.
