and their bodies soon become snowy white with a dense cov- 
ering of short wax threads. See Figure D, Plate XI. 
All of the second generation lice become winged. An in- 
fested leaf brought to the laboratory by Mr. Bragg, June 17, 
1913, had one vigorous fundatrix in the gall with a few first 
instar young, and outside the gall a large number of second 
generation lice, two of which had developed wings, probably 
the first of the year. This leaf is shown in two views at Fig- 
ures C and D. 
Another species, gravicornis Patch, described in Bulletin 
213, Maine Experiment Station, is very similar in its appear- 
ance upon the leaf, but is quite distinct. 
The Fundatrix (Plate XI, Figure E). 
General color a yellowish olive green, lighter over the middle por- 
tion of the abdomen; covered more or less heavily with white powder, 
and some threads about the margins of the body, especially poster-- 
iorly; head, eyes and tarsi blackish; legs and antennae dusky; rather 
broadly oval in form, when fully adult measuring about 4 by 3 milli- 
meters; antenna .55 mm., five-jointed, joint III longest, being a little 
shorter than joints IV and V together without spur, joint IV shortest,
