and their bodies soon become snowy white with a dense cov- 

 ering of short wax threads. See Figure D, Plate XL 



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 ). 



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, 

 joint II one-half as long as III; permanent sensoria ciliated; beak 

 very short; hind femur and tibia each about .50. 



Proportionate lengths of the joints of eight antennae of stem- 

 mothers are as follows :
