result would be spoiled, I dropped
some chloroform near the furrows,
when they ceased moving at once.

Near these larval tobacco beet-
les are seen some holes and fur-
rows in the cigar which the ma-
ture beetles and afterwards these
developing larvae had prepared.
It seems that during the fall and
winter the mature insects perfor-
ate the tobacco and also other
material such as food stuffs and
drulns, producing a round deep
hole not larer than the body of
the insect, and then deposit the
ova inside the tunneled holes wxxh-ln
after a certain length of time the
larvae seen on the plug cut toibac-

has been witnessed off and on
years ag'o and again lately by the
writer when the furrows of these
beetles had been exposed in to-
