take it at large.
Scopaeus brevi-pennis Casey (in litt.) . This is the species recorded in the pre. vious paper, without a name. It occurs
with Afhaenofraster fulva,
Oxytelus flacusinus Lec., and 0.
szqz5ectus Casey were taken with For-
mica subsericea. They probably make
galleries of their own in the ant-hill rather than dwell in the run waj s of the ant5. Atomaria mesomela Hbst.. "or one
of the other 4-inaculate species" (Bi en- del). This occurs at Iowa City with
an Aphaenogaster, the identity of
which cannot be determined with the
limited material in hand. Several
specimens were taken from one nest.
This is probably not the customary
habit of this species.
TWO CAVE BEETLES NOT BEFORE RECORDED.
BY H. GARMAN,
Two small beetles have proved so
constantly present in small caves in
the vicinity of Lexington that it seems
worth while to place them on record
as cave insects. Both have pretty well
developed eyes and may therefore live
at times in ordinary situations, but
they are perfectly at home in the deep-
est parts of caves and are at times very abundant there. In all my collecting
in ordimtry situations I have not seen
either species out-of-doors, and am
disposed to consider them true cave
dwellers.
Choleva alsz'osa, Horn. This is a
small black beetle (one of the Silphi-
dae) about 4.5 mm. in length, described
in 1885 by Dr. Horn from the Yukon
River, Alaska. Is it possible that the
low temperature prevailing in the caves
has enabled this insect to persist here
since glacial times? I have several
hundred specimens, male and female,
all taken in caves beyond the penetra-
tion of light.
LEXINGTON. KY.
Calodera cavicola, n. s.
A small,
reddish brown insect with very short
wing covers and a slender elongated
body. Head generally darker than
the body, sometimes nearly black in
a
alcoholic specimens. The middle of
the abdominal somites also darker than
elsewhere giving this division of the
body an annulated appearance. Speci-
mens taken from the caves and kept
alive seem to me to become gradually
darker in general color. It is one of
the Staphilinidae.
Length 4.5-6.0 mm. Greatest width
about 1.0 mm.
Outline of head, seen from
above, nearly circular, truncate behind, its length contained 11 times in width, pube- scent and obsoletely punctate above. An- tennae when drawn back reaching nearly to posterior edge of prothorax, gradually
enlarging from the base, finely pubescent, and with a ring of rather strong hairs on most of the segments. First to third seg- ment cylindrical, the basal largest and long- est of the three, the second and third nearly equal; fourth segment shortest, contracted

at each extremity, widest at middle; seg- ments five to ten, inclusive, similar in shape, being angular in outline and increasing in width from base to tip; eleventh segment largest, oval, truncated at base. Labrum slightly excavated medially, rounded at
sides, with a number of rather strong setae arising from its surface, its length contained about 2& times in its width from side to side. Mandible short, sickle-shaped distally, its tip acute, its cutting edge very finely denti- culate and provided with a fringe of very fine setae. Lacinia of maxilla with an
internal membranous expansion furnished
near the tip with a series of rather strong, curved spines and a dense growth of pubes- cence. Galea tapering to tip, also with a width of prothorax), its length contained 11 times in width, outline nearly cir-
cular. Elytra not quite reaching the first abdominal somite, truncate behind, with a small excavation near outer angle. Wings small and weak, not used for flight as far as observed.
Sides of abdomen nearly paral-
lel as far as the sixth somite which narrows rapidly to the seventh which is small; out- line of somites seen from above nearly
square; a groove along each side of the
abdomen with a raised outer margin.
Color pale fulvous. Head darker, some-
times nearly black. Three anterior abdomi- nal somites with a transverse black bar a little before the middle. Somites four and five with a larger, more obscurely outlined FIG. I. a, antenna of Calodera cavicola; b, labrum; c, mandible; d, maxilla; e, outline of elytron. (From
camera lucida sketches).
dense growth of pubescence distally.
Basal
article of maxillary palpus very small, cjlin- drical; second segment gradually enlarg- ing towards tip where it attains its greatest diameter; third segment largest, also enlarg- ing from base to tip; distal segment small and slender, gradually tapering towards
tip. Prothorax wider than head (width

dark area in place of the bar. These marks are obscure in some specimens, and show
best in alcoholic specimens examined with the microscope.
The species is very common in some
caves, occurring with AnophthaZmus
horni in the deepest parts. From the
character of the ligula Mr. E. A.
Schwarz thinks it may belong to the
genus Ocalea instead of Calodera.
