other substances ; and it was rechristened by Prof. Riley the Fall 
Armv-worm, or Prodenia autumnalis. 
Wishing to know how extensive Mr. Daggy’s observations had been 
with the worm, and whether it had been injurious several seasons in 
succession, and also whether specimens couid be obtained, either of 
the worms or moths, for comparison, I wrote Mr. Daggy and received 
from him the following reply : 
Bloomington, III., August 2, 1877. 
Dear Sir— Yours of the 30th of July asking in reference to Corn- 
worm moths is at hand. In reply will say, that I was at Tuscola 
until June ’76, and never saw that worm after the season 1 sent it to 
Mr Walsh, and of course have none of them now, and have no sort of 
idea what became of them. Their ravages were confined to a small 
area, so far as I was able to learn, ending with that crop of corn. Re¬ 
gretting that I cannot serve you, 
lam yours truly, 
E. Daggy. 
Besides the brief mention given above from articles already cited,, 
this caterpillar has been an object of sufficient destructive importance 
to call forth lengthy articles in the third and eighth Missouri Ento¬ 
mological Reports, where the description and habits of the insect m 
its different stages are given, as well as a comparison of this with thej 
true Army-worm ( Leuc&nia unipuncta ). A few years since, about lo7o, 
this worm made sad havoc in winter wheat in Washington county, m 
September, or after the winter wheat was up two or three inches high, 
but onlv a limited amount of damage was done to corn. 
The eggs, according to Prof. Riley, are deposited in clusters, some¬ 
times two or three deep, on the under side of various kinds of leaves, 
and very much resemble the eggs of the Unarmed Rustic, only they 
are less compressed and the ribs less distinct. There are from two to 
four broods of the worms in a season, and were it not for the numer¬ 
ous enemies that prey upon them, the ratio of increase would be so great 
as to devastate crops of their food plants every season, but fortunately 
their visits in great numbers are separated by intervals of several years, 
and then their depredations are frequently local. 
The ground color of the caterpillar is variable, generally black when 
young, but when full grown, from pale brown to dirty green, with 
more or less or pink or yellow admixed, mottled. with crimson and 
yellow and the markings in brown. Back brownish, with a narrow 
line in the middle bordered each side by a darker shade. On each side 
is a dark line that is bordered above with yellow. Below the stigmata 
or breathing pores is a line, either buff or flesh colored, bordered above 
with a wavv yellow line. Under side pale. 
The moth is variable. The fore wings are narrow, with the gen¬ 
eral color mouse gray, variegated with smoky brown, reddish ye ow 
and white, a patch of the latter color usually found near the apex. 
The hind wings are a pearly white with a narrow dark outei bor er. 
Remedies.— Where this ‘worm appears in great numbers n 
exhibits more of the Army-worm traits than any other, an 
the artificial means that are recommended for that caterpillar 
may be used for this.
