last one reaching in a somewhat tortuous course the apex. Below 
this there is a sub-terminal, dark brown line, edged with light pur¬ 
plish, with one or two fainter dark lines each side, the same series of 
lines crossing the light portion of the wings nearly at right angles, 
and being lighter through this part. Hind wings duller, with a sub¬ 
marginal band of dark and a double medial band, that is faint. Ab¬ 
domen with a dorsal and subdorsal dark brown line. 
Macrosila Carolina, Linn—The Carolina Sphinx, or Tobacco-worm 
Moth. 
The caterpillar known as the Tobacco-worm so closely resembles 
the Tomato-worm that the one is often mistaken for the other. Like 
that species this one not only feeds on tobacco, being one of the 
principal chewers of that weed, but it thrives equally well on toma¬ 
toes, potatoes, etc. The larva is dark green, wrinkled transversely; 
the body paler on the back, with whitish dots and oblique white 
bands on the sides, edged above with bluish, and short, transverse, 
black stripes. Stigmata black, with a yellow point above and below, 
except the first and last, which are orange yellow, with a black cen¬ 
tral point; all edged with blue. The terminal horn is tipped with 
rust color. When full grown it is from three to five inches long, and 
descends into the ground and changes to a brown chrysalis, two 
inches and a quarter long, with the tongue-case, three-quarters of an 
inch, standing out on one side like the handle of a pitcher. The 
early brood of these worms, that transform to chrysalids in July, come 
out as moths in a little more than three weeks, but the late ones pass 
the winter in the chrysalis state. 
The moth has both the wings gray, crossed by several wavy black 
lines. The band crossing the central part of the wings is indistinct 
on the hind wings, while there is a white spot at the base of the fore 
wings. The abdomen has a row of five orange spots surrounded by 
black on each side, and a black patch at the base. The antennse gray 
above, white beneath, terminating in a hook. Expands four or five 
inches. 
Remedies .—Where tobacco is raised, it is often a serious question 
how to circumvent the ravages of these gormandizers without so 
much of an outlay as to greatly reduce the profits of the crops. Hand 
picking is the means generally resorted to, both for tobacco and 
tomatoes, etc., in the garden. This is effectual, but is open to the ob¬ 
jection that where the plants have to be carefully examined every 
day, the time consumed makes it an expensive operation. As a sub¬ 
stitute for hand picking, it has been recommended to plant, or allow 
to grow, Jimpson or Jamestown weeds ( Datura ) either among the 
plants or around the outside of the field. When these are in bloom, 
put a little poison, arsenic or strychnine, into the blossoms once in 
every two or three days. The moths that visit the field for the pur¬ 
pose of depositing their eggs, will be attracted by these flowers, of 
whose juices they are fond, and will be killed by the poison. A 
specimen of Ichneumon fly also prjjiys upon the worm in a manner 
similar to that described as attacking the hog caterpillar, which is of 
great assistance in lessening their number.
