68 Annals Entomological Society of America  [Vol. VII, 
at Fort Collins), little star-shaped mouths (Figures 18 and 19, 0) 
appear at the apices of the more prominent lobes thru which the alate 
lice escape. Many of them appear on a single gall as shown in Figure 
18. The galls nearly always are from terminal buds, and whether 
one or more of the leaves form a single gall I have no certain knowledge, 
but apparently it is one in each case. Large galls measure as much as 
SO to 95 mm. in greatest diameter, and about 50 to 60 in the greatest 
thickness. 
The Fundatrix. Figures 15 and 16. 
One fundatrix was found in every gall opened. General color 
of body yellowish green, the yellow tinge seeming to come from a large 
number of small embryos within; nearly unicolorous throughout, 
but a little darker along the lateral margins; legs and antennz yellowish, 
the antenna blackish at tip; both antennz and legs very short; joints 
of antenna 4; joint III about one-half the entire antenna in length; 
spur two-thirds as long as joint IV; permanent sensoria ciliated. 
Length of body 5; width 3.70; constricted a little at base of abodmen. 
In general, stout, pear-shaped, the small end being at the head; covered 
everywhere with a light covering of white powder. 
Young lice and pupe in the galls are very pale yellowish and much 
powdered. There are a great number, possibly a thousand in all, 
in a gall and apparently the stem females were just in their prime and 
packed full of embryos on July 11. All of the offspring get wings 
when adult. ; 
Fundatrigenia, Figure 17. 
All alate lice with black head thorax and antenne, and dark green 
abdomens, and the thorax and abdomen are heavily pruinose with 
more or less cottony threads towards tip of abdomen, making a tuft. 
Length of body 2.50 to 3.00 mm.; antenna .85; joint III as long as 
joints IV, V and VI to base of spur; joints IV and V sub-equal; spur 
about equal to joints IV and V together; a distinct spur near the base 
of joint III; sensoria on transverse ridges, but not surrounding the 
joints; joint III with nine to eleven sensoria; joint IV, two; joints 
V and VI with permanent sensoria, only; spur with two or three sen- 
soria, usually three, scattered along its length; cauda very small, 
rounded. 
Described from lice escaping from the galls July 11, 1918.
