7500 feet. On August 9th, four more of the galls were taken 
near the Half-way House on Pike’s Peak, at an altitude of about 
9000 feet. In two of these galls there were no living lice. In 
each of the occupied galls taken (four), there was one large 
stem-female present, with a large number of her offspring in all 
stages of development up to the adult alate lice. There were 
no adult apterous lice and all that were half grown or more gave 
evidence that they were to get wings. In the breeding cages 
the alate lice began at once to deposit young with long beaks. 
In every case the lice were accompanied by a species of large 
black ant. 
The Gall. An infested leaf becomes very much enlarged, 
and somewhat thickened with the edges turned in so as to make 
a heart shaped pocket, and the apex of the leaf is extended and 
turned back as shown in Plate XV, Figure 10. The color of the 
infested leaf is yellowish green, and lighter than the healthy 
foliage surrounding it. 
Fundatrix. Figures 11 and 18. 
A very large, oval, slatey gray louse, lightly covered with a fine 
white powder, and set everywhere with delicate gray hairs above and 
below; length of body about 4.50; width 4.00; antenna, .75; joint III 
longest and almost as long as joints IV and V together; permanent 
sensoria ciliated, joints I, II, and III with numerous delicate hairs; 
beak barely attaining third coxee; hind femur .80; hind tibia .80. 
Pupa. Figure 12. 
The pupz are quite dark in color, the abdomen being very dark 
olive green and the head and thorax a rather blue slated gray; the tarsi, 
eyes and terminal joints of the antenne black. A conspicuous marking 
of the larve and pupe consists of a row of five tufts of white waxy 
secretion along either lateral margin of the abdomen. 
Fundatrigenia. 
All the young of the fundatrix, the second generation, become 
winged and leave the galls. General appearance, that of a black louse; 
abdomen olive green; thorax, head, and antenne blackish, or dusky; 
legs yellowish; tarsi dusky; wings a trifle smoky; the veins slender with 
a narrow dusky line on either side; stigma narrow, lanceolate, dusky, 
fork rising about midway on the cubital vein; length of body 3.50; 
wing 4.50; antenna (Figure 14) 1.00; joint III with 7 to 9 oval sensoria 
and a well developed spur near the base; joint IV, with two similar 
sensoria near the distal end; joints V and VI with the usual permanent 
sensoria only which are ciliated about the margins; joint III longest, | 
fully as long as joint VI with the spur; joint V slightly longer than joint 
IV; cauda a broadly rounded lobe. 
Habits for the remainder of the year unknown.
