MEMOIRS OF THE NATIONAL ACADEMY OF SCIENCES. 
Specimens from Weyer’s Cave and the adjoining Cave of Fountains were just like those 
in the Carter caves, being white, with small black eyes, and dull purple leaden antennae and tarsi. 
Those in the New Market Cave were white, with black eyes and dark lead colored antennae. 
In One Hundred Dome Cave, specimens said to have been collected one-quarter of a mile 
from the entrance were all dark, of the usual out-of door plumbeous color. 
Remarks .—It is evident that the var. pallidus has been produced by the influence of its cave 
life. Var. pallidus occurs in a cave near Salt Lake, Utah, and the specimens do not differ from 
the bleached ones in the Kentucky and Virginia caves. The trunk becomes bleached, while the 
extremities of the antennae and legs retain somewhat of the colors of the out-of-door form. None 
have been found without eyes. The shall owest caves, such as the ice-house cave, in Carter county, 
Kentucky, as well as the deeper oues, possess this variety. We also find the normal plumbeus in 
similar caves, though probably near daylight, but the inference that the pale bleached variety has 
been produced by want of light is a natural and the only possible one. It is proved by finding 
in Zwingle’s Cave a slightly-changed plumbeus associated with numerous pallidus. 
Lepidocyrtus atropurpureus n. sp. Plate XVI, figs. 3, 3 a, 3b. 
Body dark leaden-purple; eyes large and distinct; antennae smaller and shorter than usual, 
but little longer than the head; the fourth joint equal in length to the second and third together. 
The last pair of legs with rather long scales, rather slenderer than in L. marmoratus Pack.; the 
larger claw not very broad, in this respect differing from L. metallicus Pack., and being more as 
in L. marmoratus; the single teuent hair about as long as the inner smaller claw. The terminal 
joint of the spring (elater) is very short; the middle tooth much shorter than the terminal one, 
which is also short compared with that of L. metallicus. 
Length of body, without the antennae and spring, l mm . Diamond Cave. 
The species is described from alcoholic specimens in which the hairs have been rubbed off. 
In color it seems to be near L. metallicus; like that species it is stout-bodied, and has short 
antennae, but in the present species the antennae are still shorter, the entire antennae being scarcely 
longer than the head; in this respect and the shape of the end of the elater the present species 
differs from any of the other described forms. . 
Degeeria cavern arum n. sp. Plate XVI, figs. 2, 2a-2g. 
Whitish, with a slight yellowish tint; usually blind; no traces of eyes. Body of the usual 
form; antennae of great length, two-thirds as long as the body and more than twice as long as the 
head; basal joint longer than usual; fourth joint very long and slender. Legs: last joint with 
fine slender scales; the claws much as in B. grisea Pack., but the spines on the larger claw are 
less distinct and the tenent hair shorter; the spring long and slender; the second joint serrulate 
along the under side nearly to the base; third (terminal) joint long and slender, ending in three 
teeth; the terminal tooth claw-like, as usual. The collophore (Fig. 2c) is large and well developed. 
Length of body, without the spring, 3 mm . 
Fig. 2 represents an average specimen from New Wyandotte Cave, where we found this 
species in great abundance. It also occurred in Bradford Cave, Indiana; in general form and 
color it was like the New Wyandotte form, but as seen in Fig. 2c the antennae are much shorter, 
especially the fourth joint; also the end of the spring is slenderer. It has no eyes; the body is of 
the same size, and the feet nearly the same. While the Lepidocyrtus may be only an occasional 
visitor to the cave in which it was found, the present species being eyeless and bleached, besides 
being very numerous, is, without doubt, a true troglodyte. 
Specimens found in the Carter caves, especially Zwingle’s, about one-quarter of a mile from 
daylight, had antennae (Fig. 2a) with the fourth joint slightly longer than in the Bradford Cave 
examples, but much shorter than in those from New Wyandotte; and the spring (Fig. 2g) is less 
hairy. It also occurred in Bat Cave, the specimens being certainly eyeless. 
Specimens from Diamond Cave (Fig. 2d) were identical in form, color, and length of antennas 
with those living in the Carter caves. The color did not noticeably vary in specimens from any 
of the caves.
