probable that they are distinct species. I have hitherto, in July 
and August, in different years, captured a moth in our forests, 
very like the Orchard Moth above described, and which I am in¬ 
clined to regard as the parent of these forest worms. It is very 
slightly larger than the Orchard Moth; its fore wings are bright 
ochre-yellow, many of the scales sparkling with the lustre of bur¬ 
nished gold, and instead of being freckled, they are covered with 
crinkled, irregular, transverse lines of an orange color; the pur¬ 
plish stripe forward of the middle of the wings, is widened as it 
approaches the costal edge, and is prolonged upon this edge to 
the base of the wing; and posteriorly, instead of the broad band, 
there is only a spot of purple blended with orange, situated on the 
costal edge forward of the apex ; the hind wings are white. In 
my collection, I have named this species rfrgorolepia sylvadcana 
or the Forest Moth. We also have, in this State, two or three 
other species closely resembling those described, but I know 
nothing of their habits.

P. S. July 23 d .—Informed that the number of the Journal of 
the New-York State Agricultural Society for August, had gone to 
press when the above communication reached you, and that it 
could not, therefore, appear until the issue of the succeeding num¬ 
ber, as it was a topic in which our community was much inter¬ 
ested, and erroneous views were being imbibed, I handed a copy 
of it to the Salem Press, in which newspaper it was published on 
the 12th inst., and copies were mailed upon the following day, to 
my several agricultural and scientific friends throughout the 
country. A few days after it was written, from the cocoons allu¬ 
ded to, I obtained the winged moth, from which it was evident 
that the species of Jlrgyrolepia y which I had described, was pro¬ 
duced by some other worm, as yet unknown, which probably in¬ 
fests our apple trees; whilst the worm which has done so much 
havoc this season, instead of pertaining to the family Tortricioje, 
as all its habits so strongly indicated, in reality belongs to the 
Tineid;e, the family which includes the clothes moths and other 
species which subsist upon fur, grease, and various other articles 
of household stuff, and which make cylindrical burrows through
