DoWELL: FERNS ATTACKED BY LEAF ROLLER 59 
Biology of the Staten Island Association of Arts and 
Sciences, the writer commented on the attacks of this 
larva, and recorded comments in the Proceedings of the 
Section of Biology as follows:* 
“The ferns were more than usually attacked by a leaf- 
rolling insect, the larva of which had destroyed the tips 
of many of the fronds especially of the Christmas fern 
_and various species of Dryopteris. The larva was deter- 
mined by Dr. H. G. Dyar, of the U.: S. National Museum, 
oe This attack on the tips of = 
‘the fern n fronds has also been noticed by Mr. Harold W. 
 Pretz, of Allento ntown, Pa., and commented on in a letter 
ie (Aug. BN [1908]), in fn which he said: ‘Our ferns near home 
are in poor condition from the attacks of some larva. D. 
cristata x marginalis has suffered vi very much.’ It might 
be added here that the attacks of the larva were teat 
chiefly during the early part of the season.” 
The same thing had been noticed by Mr. William ie 
Maxon and was recorded in the same proceedings} for 
the meeting of the Section of Biology on December 12, 
1908, at which meeting he was present, and “ sietiohed aes 
the fact that he had noticed the fronds of Dryopteris = 
_ simulata Dav. in Maryland attacked by an insect, which | 
had spun a fine web and drawn the Pees ~ os tips: 
together.” . ,
