GRAPE-VINE. LEAVES — rGAKTERED PLUME. REMEDIES. 143 



As this insect completes its ttansformations 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 winged 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 worms 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 becoming so multiplied as to injure the vines, 

 they should be car€fully 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 th« 

 worm may not be alarmed and escape from his retreat, and thrown 

 into the fire, or crushed beneath the foot. The pupa probably 

 attaches itself to the trellis work of the arbor, roost 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 

 molhs that has ever been described. In connection with it, there- 

 fore, a few other species pertaining to the same genus may he 

 briefly noticed. The genus Pterophorvs embraces those species of 

 ALuciTiDiE 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 LoEE-wiNGED Pldme (Pterophorus lobidactylus) is of a blackish color. Its 

 fore wings are ash grey towards their bases, freckled with tawny brown atoms; to-
