darius in Europe. In this country,
Mr. E. A. Schwarz has bred in
Alabama, Sphaero$thalma 3 sanhornii
Blake, in both sexes, from the cells of an Andrenid, Nomia sp., while Dr. C.
V. Riley has bred Sfhaerophthalma
halteola Blake from the cells of an
Anthidium sp. sent him from Florida.
The Ants comprising the families
XXI DORYLIDAE, XXII FORMICIDAE,
XXIII ODONTOMACHIUAE, XXIV PON-
EnIDAE, and XXV MYRMICIDAE, will
be treated in a separate paper.
Family XXVI. CHRYSIDIDAE. This
family is represented in our fauna by
eleven genera and seventy-seven species. It forms a connecting link, through the
family Proctotrypidae, with the HY-
MENOPTERA TEREBRANTIA, and the
species composing it are among the
most brilliant colored of our wasps.
Some of the species are said to be
6-inquilines" or "guest-flies," others true parasites, but I believe all are genuine parasites. Mocsary in his recent great
work, "Monographia Chrysididarum
orbis ten-arum universi" has brought
together, in a tabular form, all the
records of the rearings of these insects and it will be only necessary for me
here to mention the habits of some of
our own species.
Benj. D. Walsh seems to be the
only one in North America who has
made a record of the rearing of a
Species in this family. In Amer. ent.,
vol. I (1868), p. 135, he records hav-
ing bred Chysis coerulans Fabr. var.
bella Cr. from Eumenes fraterna
Say.
In treating of the genus Tryfoxylon^
I have already stated having seen
Chrysis verticalis Pattn. entering the
burrows of Trypoxylon carinz from
Fox, and this species is undoubtedly
parasitic on that wasp. In Florida,
I have bred Chysis coerulans Fabr.
and C. $er,hdchra Cr. from the cells
of Pelo-paeus cementarius Drury, while
from those of Odynerus quadrisectus
Say issued Chrysis densa Cr.
I have now given a resud of the
habits of the Aculeate Hymenoptera,
arranging the families in what I con-
ceive to be their natural sequence, and
as the Chrysididae terminates the series, my address, already too long, comes
to an end.
FURTHER NOTES ON COLEOPTERA FOUND WITH ANTS. BY HENRY FREDERICK WICKHAM, IOWA CITY, IOWA. These records are offered as a con-
doubtful species and are given as addi-
tinuation of the series begun in the last tional evidence regarding the true state volume of Psyche.* Most of them are of affairs. The ants are identified by new, either as to the beetle or its host Mr. Theo. Pergande, whose authority and the few others relate chiefly to is amply sufficient guaranty as to cor- rectness. Most of the Staphylinidae are

Casey, and many of them have only
lately been described by him ; the few
manuscript names are given as being a
trifle better than none because it will
be at least possible to ascertain the
identity of the species recorded by
reference to his cabinet. The Scyd*
maenidae were named by Dr. Brendel.
My thanks are due to all these friends
for aid in the very difficult groups
which have to be investigated in this
class of work.
Ptomaj6hagus -parasitus Lee. I
took several specimens at Iowa City in
the nest of Formica subsericea Say.
This ant supports a host of inquilines
and parasites as the following record
of species will show. All of those
credited to it were taken from a single
large nest on the same afternoon.
Scydmaems rasus Lec. One spec-
imen at Iowa City, with Lasius niger
L*-t
Scydmaenusftavi/arsis Lec. With
Formica sz~b.cericea, one specimen.
Eumicrus motschulskii\^ec. ("Ap-
parently a large specimen of this species and certainly not grossus"), one spec-
imen with Lasius nig-er at Iowa City.
Adranes lecontei Brend. Found in
the autumn, at Iowa City, in the nest
of a Lasius which Mr. Pergande thinks
may be a variety of L. minutus Em.
In the spring, I take it with L. a$hidi- cola Walsh.
Ceo$hy/lus monilis Lee. Occurs
at the same time and in the same nests
as the preceding species.
t Mr. Pergande writes that this is the form hereto- fore considered identical with L, alienus. Ratris?,ts lineathlh's Aub6. Taken
with Formica sitbsericea. Only two
or three specimens obtained.
Atheta iowana Casey (in litt.) and
A. ternzivzata id., both occur with F.
subsericea. Atheta Zimatula id. was
taken at Iowa City with Lasius niger
while A. exilissima id. was captured
with Sole?zofis debilis at Canon City,
Colo.
Lomechusa cava Lec. At Iowa
City with Cam$onotus $ictus Forel.
Several specimens are often to be found
in the same nest.
Myrmedonia calignosa Casey. With
ants at Iowa City, April 20. No spec-
imens of the host were saved.
Myrmecochara crinita Casey. This
is the species which was most unfort-
unately referred to Gyrophaena in the
first paper. I am intebted to Mr.
E. A. Schwarz for first calling attention to my error. Mr. Fauvel considers '
the insect as constituting a new genus
but now that it has received a specific
name it will be a matter of no great
difficulty to keep track of it in the
future.
Mcrodonia occi~alis Casey. With
ants, at Walnut, Arizona, July 21.
Two specimens.
Myrmobiota crassicornis Casey. At
Iowa City with Lasius niger. Two
specimens.
Heterotho$s fumiyatus Lec. With
Formica subsericea, It is more often
to be found at large than in ants' nests. Philonthus microj6h/haZmus Horn.
One specimen with 3'. subsericea.
I
once got another specin~en with an ant




================================================================================

(Afhaemg-aster fdva) but usually
take it at large.
Scofaeus brevipennis Casey (in litt.) .
This is the species recorded in the pre- vious paper, without a name. It occurs
with Afhaenogaster fulva.
Oxytelus 'placusinus Lec., and 0.
suq5ectus Casey were taken with For-
mica subsericea. They probably make
galleries of their own in the ant-hill rather than dwell in the run wajs of the ants.
Atomaria mzsomela Hbst.. "or one
of the other 4-rnaculate species" ( Bren- 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 ordinary situations I have not seen
either species out-of-doors, and am
disposed to consider them true cave
dwellers.
Choleva alsiosa, Horn. This is a
small black beetle (one of the ~ilphi-
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.
CaZodera 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
9
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 Iong- est of the three, the second and third nearly equal ; fourth segment shortest, contracted
