AGRICULTURAL REPORT. 
brown color; the upper-wings light-brown, with a hand of darker 
brown, running obliquely across them near the centre (one specimen 
had two dark oblique lines on the upper-wing) ; a dark triangular 
mark occurs on the upper side of the wing; between the margin and 
band, and the margin itself is of a dark-brown ; the under-wings are 
vellowish-hrown ; the under side of the wings is brown, marked 
crosswise by darker lines, giving it somewhat a marbled appeal ancc, 
and the antennae are threadlike. The distinguishing feature of this 
small moth is the very long and dark-colored palpi, which are some- 
what curved upwards, and project from the front of the head like a 
trunk. 
The damage done by these small insects is not so apparent at first 
as that caused by those of a larger size, such as the boll-worm and 
others ; yet, no doubt, many of the buds and leaves on the terminal 
shoots are destroyed by them. These webbed-up leaves, however, 
must not he confounded with the webs made by numerous small 
spiders, which also select such places for their abodes, and no doubt 
do good by destroying many young caterpillars and moths. 
Young cotton-buds are frequently observed at the end of the ter- 
minal shoots, turning brown, and eventually dropping oft. ibis has 
been attributed to the agency of the young larvm of the ‘‘bore-worm, 
or “boll-worm,” which certainly are sometimes found in the terminal 
shoots of cotton; but, when this is the case, the buds are generally 
either eaten from the outer calyx, or the bud itself perforated and the 
former flaring open; whereas, the buds, which turn black, as before 
described, are closely enveloped in the outer calyx, and present a 
triangular form with a dry and^dark-brown appearance. 
THE COTTON LYGiEUS. 
. ( Lygceus ?) 
Upon close examination, a number of extremely minute larvae, 
(PI. VH. fig. 4,) measuring a little over one-twentieth of an inch in 
length, were found in the injured shoots. The insects, when confined 
in a bottle with some young terminal cotton-shoots and buds, to 
ascertain if they really injured the plant, were observed immediately 
to attack each other with great animosity ; and, in a short time, one 
of the strongest larvae killed and sucked out the juices from three of 
its companions, and also from a cotton-louse which had been placed 
in the glass. The same insect, however, was afterwards plainly seen 
on several occasions, to suck sap from the terminal shoot and. young 
buds ; and as there were no more insects for it to feed upon, it must 
necessarily have perfected its growth and transformations afterwards 
on vegetable juices alone. Almost every terminal shoot which was 
diseased had in it one or more of these minute larvrn or perfect insects. 
The pupte are of a reddish-brown, about one-twentieth of an inch 
in length, with eyes of a reddish-brown color. The perfect insect is 
rather more than one-twentieth of an inch in length, also with reddish- 
brown eyes, yellowish antennas, and a head and thorax black ; tbe 
triangular space between the wings is black ; the wings are brown-
