ants. Other deltoids are known to feed upon dry leaves, but no lepidopterous larva 
has ever been observed to live upon the excrements of any animal. 
The larva? taken in January were full grown and were evidently hibernating. 
Two specimens formed naked pupa?, which were finally destroyed by mold, and I 
failed to breed the moth. In July the larva? found were young, and proved to be 
exceedingly delicate and difficult to rear. Most of the specimens immediately died 
when taken from the cool retreat of the gopher and exposed to the light and heat of 
the sun. By taking extraordinary precautions I at last succeeded in domiciling 
two specimens in a tightly closed Mason jar, partly tilled with moist sand taken 
with them from the gopher hole. I supplied these caterpillars with fresh dung 
from a gopher kept in confinement. They fed upon this at night, or when the jar 
was darkened by a thick covering. When captured (July 18) they were about one- 
third grown. In three weeks they consumed or disintegrated about three cubic 
inches of the dung placed from time to time in the jar, and nearly doubled in size. 
In August they were taken North to Detroit, Mich., where they soon began to hiber- 
nate and stopped feeding. Both subsequently died without pupating. 
ORTHOPTERA. 
(10) Ceutlwpliilus latibuli Scudder, n. sp. — This wingless cricket is found in all 
stages of growth and in great numbers in every burrow. They crawl readily along 
the sides and roof of the gallery, waving their long antenna and behaving in much 
the same manner as their relatives in the caves. 
CHERNETID.E. 
(11) Chdanops affinis Banks, n. sp. — Five or six specimens of a pseudoscorpiou were 
taken in the debris at the end of the galleries. One was collected in January; the 
remainder in July. 
IXODID.E. 
(12) Ornitlxodorus americanus Marx, MS. — The young of this tick infested one of 
the burrows opened in July. They were full of the blood of the turtle, but had not 
attached themselves to the body of the animal, and I conclude that they do not do 
so until they become adult. The mature ticks are sometimes found upon the gopher, 
adhering to the leathery skin behind the legs, after the manner of ticks generally. 
The young ticks of all sizes, to the number of twenty or more, were found in the 
terminal debris, and scattered along the gallery half way to its mouth. The spe- 
cies has been found in Texas in the nostrils of horses, and upon the llama in South 
America. 
(13) Amblyomma tuberculatum Marx, n. sp. — A single specimen of this large and 
handsome tick was found attached to one of the sutures of the under shell of a large 
gopher, with its beak firmly inserted in the ligaments. I have no further knowl- 
edge of its habits. * 
This interesting association of messmates and parasites of the gopher 
tortoise forms a distinctly subterranean fauna, in which the genesis of 
trne cave life is very instructively shown. The differentiation of the 
various forms from their allies above ground has, it is true, not pro- 
* Thelyphonus giganteus Lucas. — A very large specimen of the Whip-tailed Scor- 
pion was found in a small gallery of its own, connecting with that of the gopher at 
a point about six feet beneath the surface of the ground. It is merely an intruder, 
and probably feeds upon the crickets. 
A flea found in one of the burrows was probably left behind by some mammal 
that had visited the gopher hole.
