raised above the surface and indicated by a dark ring; antenna .55 to 

 .65; joints III and VI with its spur, about equal; joints II and IV, 

 about equal; joint IV about .80 as long as joint V; joints II and IV 

 are about two-thirds as long as joint III or VI ; spur about one-fifth 

 as long as joint VI; body about 1.30 to 1.60; cauda broadly rounded; 

 ventral wax plates about .25 in diameter. 



Male. The male is very slender compared with the forms above de- 

 scribed and varies in general color about the same as does the oviparous 

 female, the prevailing color being pink at first, the color changing to 

 a brownish yellow with age; head, thorax, antennae and wing veins, 

 blackish ; eyes bright red ; anal plate black ; anterior wings with cubital 

 vein twice forked ; posterior wings short and narrow and with one 

 transverse vein only, rising at a point about twice as far from the base 

 of the wing as from the tip. Length of body, .95 to 1.05; wing, 1.40 

 to 1.50; hind wing, .85 to .90; antennae, i.io; joints III, IV, V, and 

 VI with its spur sub-equal; posterior wing .90; wing veins all heavy 

 and with narrow dusky margins ; stigma of fore-wing lanceolate, nar- 

 row and translucent ; sensoria of antenna about as follows : Joint III, 

 4 to 5 ; joints IV to VI, with 5 to 7 sensoria but usually 6; all sensoria 

 oval or circular and the permanent ones surrounded with cilia ; anten- 

 nal joints very rough and irregular in outline; beak attaining third 

 coxae. A day or two after becoming winged, the males have a few 

 long, fluffy cottony threads over head, thorax, and abdomen, even the 

 legs and antennae being more or less covered with these threads and 

 a powdery secretion. 



Eggs. The eggs are deposited singly and are covered with short 

 fragments of waxy secretion from the two large wax plates that are 

 on the posterior ventral surface of the abdomen. The oviparous female 

 places these broken wax threads upon the egg while she is depositing 

 it, by means of her hind tarsi which she rubs over the dense mass of 

 short wax threads and then over the egg. I have watched a similar 

 process in species of Lachnus. The color of the recently laid eggs is 

 pale green and in shape they are broad oval, being approximately .50 

 x .30. The eggs observed were all deposited in a breeding cage and 

 were scattered promiscuously over either the upper or lower surface 

 of the oak leaves. 



The fundatrix and alate virgogenia I have not seen. 



Mr. Asa C. Maxson, Longmont, Colorado, recently sent me 

 a closely allied but apparently distinct species from the leaves 

 of the live oak taken at Spreckels, California, June 28, 1913. 

 In this sending there were both oviparous and viviparous fe- 

 males but no males or other allied form. These lice differ 

 from those taken from the scrub oaks in Colorado by the more
