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 I 'irgogcnia. 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, 

 i.io; antenna, .50; joints II, III, IV, and V vary but little in length; 

 joint III is usually the longest of those mentioned, but always shorter 

 than joint VI with the spur; joint IV 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 nu 

 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 thread 

 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 am! set with a large number of oval scent glands; beak just 

 surpassing the second pair of coxae, the tip only being black ; pores not
