It seems to be abundant throughout the Southern States, but I do 
not know of its occurrence north of the latitude of Central Illinois. 
The destructive outbreaks which I have encountered in my reading 
on this species, occurred as follows: In 1845 and 1854, in Georgia; 
1868, in Central Illinois and Northeastern Missouri; 1870, Kansas! 
Illinois and Missouri; 1872, Central Georgia; 1878, Washington 
county, Illinois; and 1881, in Georgia. 
In Illinois, this autumn, we found it generally distributed in de¬ 
structive numbers throughout the eastern two-thirds of Tazewell 
county and all of Mason county. From D. S. Harris, of Cuba, in 
Fulton county, and from E. Boyer, at Lewiston, I heard that it 
had generally prevailed in that county. Letters from Menard, Mason, 
Macon and Madison counties to the east and south,_ and from Stark 
on the north, reported no occurrence of the worm in those regions, 
and fixed the limit of the outbreak in those directions; but to the 
west it extended to the Mississippi river, having been reported by 
correspondents in both Pike and Hancock counties. The area 
infested was therefore a triangular one, the apex of the triangle 
being near eastern McLean county, and the base extending along the 
Mississippi from Pike to Hancock. 
LIFE HISTORY. 
In 1854, the caterpillars were abundant in Georgia during the 
last days of September and the beginning of October. “When about 
to change,” says Glover, “they formed cocoons of silk under stones 
or in the ground near the surface, interwoven with particles of 
earth, and came out perfect moths from the 24th to the 80th of 
October; and, as these specimens were kept in a room without arti¬ 
ficial heat, I conjectured that those in the open field would appear 
about the same time.” They were also believed to have injured the 
rice in that State in June of the same year. 
In Missouri, in 1868, the larvae were received by Eiley on the 10th 
of October. They came to their growth the latter part of October 
and entered the earth, where Eiley believed that they would pass 
the winter in the chrysalis state. 
In 1869, Walsh and Eiley received specimens from Central Illinois 
in July, and the moths made their appearance towards the end of 
the same month. ^ 
In 1870; Eiley expressed the opinion that there are at least two 
broods, and probably three or four in a year. “Those worms which 
appeared,” he says, “in such multitudes in August and the fore part 
of September, in due time produced moths, and these gave birth to 
a new generation of worms, which began to make their presence 
manifest towards the end of October. And it will be remembered 
that, as stated in our last number, we bred the moth as early as 
July, in 1868, from worms received from Mr. Daggy.” 
In the above year they were noted in Central Missouri on the 
26th of August. In 1881 they occurred on the rice in Georgia, in 
May, going into the ground for their transformation in the first ana 
second weeks in June; and a later brood occurred in August. 
During the present autumn they were first noticed by our corres¬ 
pondents during the third or fourth week of September, at which time
