whitish patches gradually enlarge until the leaf has a mottled 
appearance and in severe infestations, the entire leaf becomes 
yellowish brown and withers completely. The under sides of 
the leaves also become covered with the brownish excrement 
of the nymphs and adults. Where the plants were growing in 
the sun, most of the insects were found on the under sides of 
the leaves, but in shaded situations and where the foliage was 
dense, many nymphs were found on the upper surfaces. After 
the second stage, the nymphs seem to migrate somewhat and 
feed singly and in colonies on any portion of a leaf which is 
shaded. No particular portion of a plant seems to be pre- 
ferred as entire bushes were found infested from top to bot- 
tom. ; 
On July 7, 1914, a few adults and all stages of the nymphs 
were found. On August 15, 1915, adults and nymphs were 
very abundant, and on September 1, 1915, adults and last stage 
nymphs only were present. It is quite possible that there are 
two generations each season and that the adults hibernate. 
Egg. Length, 0.36 mm.; greatest width, 0.22 mm. The 
somewhat flask-shaped, smooth, whitish eggs were found on 
the under surface of the leaf, inserted as a rule in the mid- 
rib, but sometimes in the leaf tissue adjoining the mid-rib. 
Usually they occurred in small clusters, being stuck sometimes 
vertically in the tissue and at other times at an angle. The 
necks of the eggs seemed to be bent slightly so as to bring the 
caps on a level with the leaf surface. Where many eggs were 
found in a mid-rib, a distortion was present, the rib extend- 
ing out on one side and being thickened at that point. The 
tissue surrounding the eggs was somewhat hard and corky 
and each egg-cap was topped by a brownish scab-like crust 
evidently deposited by the parent insect.
