Kinsey: Gall Wasp Genus Cynips 
293 
Probably restricted to a limited area that lies east of Phoenix in 
Arizona. Figure 45. 
TYPES. — 1 female and galls (the galls possibly confused with ma- 
terial of some variety of dugesi ) ; in the Kinsey collection. Labelled 
Globe, Arizona; January 20, 1920; Q. g rise a; Kinsey collector. 
Most of the insects of this variety had emerged at Globe, 
Arizona, before January 20 (in 1920), but the type female 
emerged after that. 
It is never good practice to publish a new species on the 
basis of a lone specimen, but it is perhaps permissible when 
the new form is clearly differentiated from a group of related 
things whose variation, range, and host relations we already 
understand.

FEMALE. — The head entirely rich rufous, or rarely blackish on the 
face medianly; the antennae rufo-brown, more rufous on the first two 
segments; the thorax of moderate size, rich, bright rufous, darker 
brownish rufous in places; anterior parallel lines rather broad; lateral 
lines rather broad, not long; scutellum rich, bright rufous, moderately 
rugose, flattened or even slightly depressed along a median line, with 
two more or less defined foveae which are largely smooth and only 
shallowly sculptured; pronotum rich, bright rufous; the abdomen mostly 
dark rufous, lighter rufous antero-laterally and on the hypopygium; 
the hypopygial spine of moderate weight; legs including the coxae wholly 
rich, bright rufous; wings not quite full length, about 1.15 of the body 
in length; the first abscissa of the radius without a projecting point; 
the second abscissa with a moderately swollen tip; areolet moderately 
large; an indefinite, very light, smoky patch near the base of the cubital 
cell and a very few, indefinite, light colored spots nearer the tip of the 
same cell; the radial and aiscoidal cells unspotted; a slight infuscation 
at the break in the discoideus; length 2.7 to 3.9 mm., averaging nearer 
3.4 mm. Figures 270, 283. 
GALL. — A large, gourd-shaped leaf gall with a spherical body, 
with fine, dense fibers supporting the central larval cell. Monothal- 
amous. Most of the gall strictly spherical, up to 22.0 mm. in diameter, 
drawn out into a short, rather stout, more or less cylindrical base 
which may be as much as 3.0 mm. in length and 3.0 mm. in diameter; 
the surface essentially smooth but not very shining, microscopically
