The only one of these varieties with full-length wings is 
simulatrix, of southern Arizona and New Mexico. Variety 
dugesi has a fifteen per cent reduction in the wing length, 
which is the same as the reduction in the related species cava. 
This shortening is distinct but so slight as to readily pass 
unnoticed ; and dugesi and cava are the only species of Cynips 
in which there is any wing reduction less than forty per cent 
of the length normal for the subgenus. Two other varieties 
of dugesi , namely pupoides and brevipennata from southern 
Rocky Mountain areas in West Texas, northern New Mexico, 
and southern Colorado, have the wings reduced thirty-three 
and thirty-seven per cent, this reduction being marked, altho 
all of the veins are still represented in the reduced wings. 
The modifications of the proportions of the thorax are slight 
altho evident.

FEMALE. — Head dark rufous, darker to black over much of the 
face; antennae dark brown, dark rufous on the first two segments only; 
thorax rufous to dark rufous, darker to black in many places; the 
abdomen mostly piceo-black, only limitedly ruf o-piceous ; the legs wholly 
dark rufous, brightest basally; head somewhat narrower than the 
thorax; parapsidal grooves moderately convergent at the scutellum; 
foveae largely smooth but sparingly, irregularly sculptured at bottom; 
wings long, 1.35 of the body in length, extending for half their length 
beyond the tip of the abdomen; first abscissa of the radius distinctly 
angulated at something more than 90°; second abscissa of the radius 
ending in a (usually) rather large, angulated tip; radial cell short but 
distinctly longer than wide; areolet large to very large, elongated on 
the cubitus; the spots well removed from the basal blotch in the cubital 
cell; length 2.8 to 3.2 mm., distinctly larger than the other varieties of 
the species. Figures 264, 266, 276, 287. 
GALL. — As described for the species. Apparently not to be dis- 
tinguished from other varieties of dugesi, nor from Cynips bella bella 
which occurs in the same region. On leaves of Quercus undulata, Q. 
grisea, Q. oblongifolia, Q. arizonica , Q. Gambelii, and probably related 
oaks. Figure 263. 
RANGE. — New Mexico: Magdalena ( Q . grisea, acc. Weld in Kin- 
sey coll.). Near Alamogordo at 7000 ft. (galls, Q. undulata and Q. 
arizonica, Kinsey coll.). Highrolls (galls, Q. undulata, Kinsey coll.).
