As this insect completes its transformations so early in the sea¬ 
son, it is quite probable there are two generations of it annually, 
the moths which come out the first of July laying their eggs for 
another brood of worms at a later period, when the foliage upon 
the vines will be so dense that they will be much less liable to be 
noticed. Whether this second generation completes its trans¬ 
formations and the w'inged'moth appears in autumn, and deposits 
its eggs to be hatched the following spring, or whether it only 
reaches its pupa state, and thus remains through the winter, 
future observations must determine. The former, however, ap¬ 
pears most probable. 
When these tvorms are neglected and are permitted to feast 
unharmed upon the foliage of the grape vine, unless they are kept 
in check by their natural enemies, they will be liable to appear 
in increased numbers, with each succeeding generation. To pre¬ 
vent them from becuming so multiplied as to injure the vines, 
they should be carefully sought for in the fore part and middle 
of the month of June. Wherever one or two leaves are found 
drawn together by cob-web like threads, forming a lurking place 
for one of these worms, they should be picked off, gently, that the 
worm may not be alarmed and escape from his retreat, and thrown 
into the tire, or crushed beneath the foot. The pupa probably 
attaches itself to the trellis work of the arbor, most commonly, 
during the few days that this stage of its life continues, and if 
any of these happen to be seen, they also should be. crushed, or 
cut asunder with a knife. 
This, I believe, is the first American species of this family of 
moths that has ever been described. In connection with it, there- 
fore, a few other species pertaining to the same genus may be 
briefly noticed. The genus Pterophorn's embraces those species of 
Alicitidje which have the fore wings divided into two and the 
hind wings into three lobes. The two first of the following spe¬ 
cies have several points of resemblance to the Gartered Plume, 
but are much darker colored, and are otherwise clearly distinct 
from it. 
The Lobe-winged Plume (Pterophorus lobidactylus) is of a blackish color. Its 
fore wiags are ash grey towards their bases, freckled with tawny brown atoms; to-
