NOTES ON THE WINTER INSECT FAUNA OF VIGO COUNTY, INDIANA.- V.
BY W. S. BLATCIILEY, INDIANAPOT.IS, INDIANA. COLEOPTERA (CONT. ) .
A number of beetles belonging to the
families Dytiscidae, Gyrinidac and Hy-
drophilidae, doubtless pass the win-
ter as imagoes,* hibernating in the
waters of the deeper pools of ponds and
streams, or beneath the mud and drift-
wood near their margins. The oppor-
tunity did not occur to make a special
investigation of such pools, and there-
fore but two species of water bcetles
were taken, during the winter collecting. 78, Seroszis striatus Say. The
only specimen taken in the county was
found Feb. 26, deeply buried in damp
sand, beneath a log on margin of old
canal.
*Imagoes of the genera Dytiscus and Hydrophilus have been seen by the writer on numerous occasions in early April.

The above were taken on several oc-
casions beneath log's close to carrion.
Sui'inamcnsis is found only singly or in pairs. Inequalis is gregarious, winters
in different stages, and in Indiana is
the most abundantly represented species
of the family.

specimen, Dec. 5, from beneath a rail
in upland field.

One or two of each of the above were

in fungi in summer ; the others are rare at all seasons.

95, S. cinnamo&er~ts Grav.
Of eight species of this genus known
to occur in the county the above three
were the only ones taken in winter.
S'. cinnamo'ptems is the most common
of all. and hibernates beneath beech and oak logs ; the others, beneath logs and
cliiinks near decaying animal matter.
In summer all are found in fungi.
S. vzdpi~f,zts Nordm. has been taken
on April ist, and probably hibernates.

Of the above, P. bmn~eus is corn-
mon, the others scarce. All hibernate
beneath logs and rubbish in fence
corners which are filled with dead
leaves. The only specimen of X. ce-
phalus taken was rolled up like a rib-
bon and did not move until after it had
been in the cyanide bottle for some sec- onds.
loo, Stenus colonzts Er.
101, S. annularis Er.
But the two members of this large
genus have been recognized in the
county. S. colonus is very common in
winter beneath and between the radical
leaves of mullein ; S. anmdaris much
less common beneath logs and rubbish.

Of these C. bad& has been taken
but once in winter; the others on
numerous occasions beneath bark,
chunks and mullein leaves. C. $aZ-
lipes frequents damp, sandy places.

These five species represent the
genus, as far as known, in Vigo
County. L. armatam is very common
beneath logs in low, damp, sandy
places; L. simplex rare in winter;
and the others frequent beneath bark
and logs in uplmd woods.

logs.

The last two species occur in moss
and beneath chunks in dense upland
"woods.
Besides the above-named 31 species
of Staphylinidae five additional ones
were taken in winter which are as yet
undetermined. Seventynine members
of the family have been collected in
the county, and doubtless many small
ones occur which have been over-
looked. A careful and systematic
collecting carried on through several
winters would probably show that the
large majority of the species arc repre- sented in winter by the imago.
