ingly active, and crawled backward as freely as forward. I could 
scarcely believe my eyes when I sawit. I had fully expected to have 
seen a common cut worm or the true wire worm; but instead, after a 
hasty examination, I recognized the larva of Crambus caliginosellus. 
We obtained two larvee from this plant and were not long in finding 
others near by. ; 
This part of the field was rather rolling and a good gravelly soil. 
The uninjured tobacco had a leaf-spread of from 10 to 12 inches. A 
few rods beyond, where the soil was not so gravelly, and better, we 
found the larve had literally destroyed the first and second plantings 
and were at work upon the third, damaging it severely, although the 
ground had been replowed before the last planting. Here and there 
was a young plant just beginning to wilt, and invariably we found the 
larva at work either in the stalk or at the base of the plant just below 
the surface of the ground. So far as I could ascertain the attack is 
always at the surface or just below. In many instances the larve had 
hollowed out the stalks from the base of the roots to the branches of 
the first leaves. Many plants were gnawed irregularly around the 
stalk below the surface, and some, in fact, were completely cut off at 
the surface, the insect always working from below. 
In the great majority of cases the larve were found in a small mass 
of web near the plant, and sometimes within it. In one plant, less 
than 6 inches high, we found four larve within the stalk, but as a rule 
only a single one was present. 
We found no pupe, although a diligent search was made for them. 
Many larvee, from one-third to full grown, were collected. Two were 
found about an inch below the surface that were just beginning to 
pupate in cells lined with a delicate silk. 
Part of this same field, containing in all about 12 acres, was planted 
in corn, and the same Greece had totally destroyed about anacre. Only 
a Stalk here and there was left standing in the infested area, while 
that surrounding was knee high. Many of the larve collected from 
the corn were a little lighter in general color than those found upon 
tobacco. This we would naturally expect, as the general color depends 
largely upon the contents of the ULC oaiie canal, and masticated corn 
is ighter than tobacco. 
Corn attacked by this insect, and not killed outright, is dwarfed, and 
generally stools at the base. Sometimes the terminal leaves are wrin- 
kled and twisted, giving the plant an upside down appearance, as if it 
was trying to push the terminals in the ground. Corn is most seriously 
damaged by this pest when it is quite young. The larve attack corn 
very much in the same manner as tobacco, cutting and burrowing it out 
just below the surface of the ground. 
An examination of other neighboring fields revealed the fact that the 
pest was present in very destructive numbers. In one field, belonging 
to Mr. A. W. Neale, about 22,000 plants had been destroyed by it. To
