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 i, 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.
