where the species was very common, infesting, for the most 
part, the under (ventral) side of the leaves. The lice were 
readily detected by the cottony secretion which they produce 
in great profusion. I found very few of the summer form, 
but large numbers of oviparous females in all stages of de- 
velopment and also a large number of pupae, all of which 
were developing into males. A single winged male was also 
found. The lice seemed to prefer a folded leaf, and colonies 
were frequently found in folds that had been produced by leaf- 
rollers or other causes. The punctures of the insect do not 
seem to have much, if any, effect to cause the curling of the 
leaves. 
Apterous Virgogenia. This form had mostly disappeared. The 
examples taken were light green, the color being strongest along the 
lateral margins of the body; body everywhere covered more or less 
densely with loose cottony secretion; eyes bright red: head and thoracic 
segments, antennae, except the terminal segments which are somewhat 
dusky, and legs yellowish to yellowish brown in color; length of body, 
1.10; antenna, .50; joints II, III, IV, and V vary but little in length; 
joint IIT is usually the longest of those mentioned, but.always shorter 
than joint VI with the spur; joint ITV usually shortest, and even joint 
II sometimes exceeds joint III in length. The only sensoria present 
are the permanent ones on joints V and VI. The length of the body 
as given above may be too little, as the specimens taken are rather 
old and the body segments are somewhat contracted. 
Oviparous Female. The color in this form varies, some examples 
being uniform straw yellow throughout, while others are as uniformly 
pink, and others are pale yellowish green. Body everywhere covered 
more or less densely with loose cottony secretion, the wax plates show- 
ing very plainly as minute dark dots upon the dorsum, there being 
three longitudinal rows on either side of the body, with the usual re- 
duction in numbers upon the thorax and terminal segments of the 
abdomen; two large circular wax plates of remarkable size occur on 
the under side of the abdomen upon joints V and VI and partially 
covering joint VII, each of which has two pores or clear spots in it. 
These plates are covered with a dense deposit of short wax threads 
making two very conspicuous white patches which may be seen pro- 
jecting beyond the lateral margins of the abdomen when viewed from 
above; eyes bright red; antennae, legs, head, anal plate and gland plates 
dusky in color; hind tibiae and antenna quite dark; hind tibiae much 
swollen and set with a large number of oval scent glands; beak just 
surpassing the second pair of coxae, the tip only being black; pores not
