286 The Cave Beetles of Kentucky. [May, 
which strew the pathways of that wonderful cave. One could 
almost hear them, in the stillness of the Titanic corridors and 
domes of that magnificent cavern, exclaim over a newly fallen 
drop of tallow from our candles, ‘‘ Here’s richness!” 
A few beetles were found in these caves which had evidently 
found their way in from out-of-doors, as they had eyes and did 
not differ from normal specimens. They are figured on the ac- 
companying plate. Figure 1 represents Batrisus spretus LeC. 
(much enlarged), one of the family Pselaphide ; two females 
were found at the end of Dixon’s Cave. It is a common beetle, 
and ranges from Vermont to Georgia, according to Dr. LeConte. 
Figure 12 represents Quedius fulgidus (much enlarged). It oc- 
curred in Dixon’s Cave and also in Weyer’s; it is a common 
species in the Middle and Western States. This and two other 
Staphylinide or rove beetles, represented by Figures 6 and 7, 
and a larva of this family (Figure 9) occurred in different caves 
and all had eyes, being evidently fresh arrivals in these subter- 
ranean retreats. 
It was a matter of much importance to discover the larve, or 
young, of the blind beetles, the true autochthones of these caverns, 
in order to ascertain whether the young are born blind, particu- 
larly as the larve of these genera, so far as we know, had not 
yet been discovered in Europe. Systematic research in different 
caves soon revealed several larvæ, both of Anophthalmus and of 
Adelops. The young Anophthalmus occurred in several caves; 
particularly in Salt Cave, on damp sand-banks, under stones. 
Figure 3 represents what is without much doubt the larva of A. 
Tellkampfii. This larva is more closely allied to that of the Eu- 
ropean Pterostichus nigrita, figured by Schiddte, than any other 
oe with which I have been able to compare it, but the body 18 
rather slenderer, the head much longer and narrower, and .the 
mouth-parts longer, while the caudal appendages are shorter. 
The end of the body is like those of Harpalus and Stenolophus, 
as figured by Schiddte, but the mandibles resemble those of Har- 
larva from Bat Cave, one of the Carter caves. igure 9, larva of a Staph;
