pupae of an unknown insect. Those plants, the roots of which had 
been attacked, died off; and the spot to which the insects had fast¬ 
ened themselves on the still soft straw within the sheath of the leaf, 
was found to be brown, withered, and tough, yet without any appa¬ 
rent wound. The straw -which had become lodged, produced small 
ears, with few and imperfect grains, which ripened with difficulty, 
and the straw was twisted, and of a very inferior quality.” 
Nearly a hundred miles south-west of Saxe-Altenburgh, a similar 
account is simultaneously given by Baron Von Meningcr, agricul¬ 
tural director of the Duke of Saxe-Coburg. According to his re¬ 
port, “In the fields of Weikendorf, and other neighboring localities, 
caterpillars were found which had devastated whole fields. These 
caterpillars had their first abode near the ground, in the first joint 
of the straw, where they were found in whole families, in a sort oi 
nest. The largest were about the length of two.lines. Their colon 
was pale green, with a small black dot above.The 
straw became dry at the first joint, and fell over or leaned on its 
neighbor. The upper part of the straw received its nourishment 
from the atmosphere alone, and the ears formed : but they continu¬ 
ed in a sickly condition, and could only produce small, shrivelled 
grains. The life of the caterpillars (their duration as naked worms'?) 
appeared to be from about twenty-four to thirty days. As the straw 
ripened, the insects changed their color into a brownish hue, shriv¬ 
elled up, and finally disappeared.” 
M. Kbllar, who seems to have known nothing of the American 
history of 11113)05601 beyond what he gathered from Mr. Say’s brief 
account, obtained some of the diseased straw from Germany, in 
which, he says, “ many of the brown pupa: were found. I opened 
the pupa-case, and was able to determine with great probability, 
partly from the form of the pupa, and partly from the unchanged 
caterpillar in the pupa-case, that it must be a small fly. I only as¬ 
certained this from the minute description and drawing of the insect 
from Mr. Thomas Say, in a North American journal, in which a 
stem of wheat, with the pupa within it, is exactly represented as I 
have seen our wheat.” 
Mr. Westwood, in a note appended to this account, says, it is 
perhaps questionable whether the species, of which the above de-
