Kinsey: Gall Wasp Genus Cynips 
85 
sometimes the entire abdomen has a not dense coating of hairs, or (in 
the agamic forms of the subgenus Besbicus and in still other agamic 
forms) the sides of all the abdominal segments are well coated with 
appressed hairs. Hypopygial spine of agamic forms large but not ex- 
tending much further than the lateral lobes of the hypopygium; the 
spine distinctly broad, in some instances very broad, a broadened area 
usually nearer the tip than the base of the spine (in most wingless 
forms of the subgenus Acraspis the spine is of uniform width for its 
whole length) ; sometimes the dorsal point, sometimes the ventral point 
of the spine extends furthest; much of the spine punctate and hairy, 
the tip bearing a tuft of long, yellowish hairs; the whole spine a little 
smaller in short-winged forms and still smaller, narrower, and less 
hairy in bisexual forms. Ventral valves not prominent. 
Legs long, wholly punctate and hairy; tarsal claws usually of 
moderate weight, heavy in the subgenera Besbicus and Philonix; usually 
strongly toothed, less strongly toothed in bisexual forms, in a few 
agamic females only weakly toothed. 
Wings usually long, extending fully one-half of their length beyond 
the tip of the abdomen; or wings reduced to three-quarters or to half 
the normal length; or wings reduced still further, being in many cases 
mere stubs; the shortened wings with reduced venation. If long, the 
wings are clear or slightly tinged with yellow, set with short, dark 
hairs which form a short fringe about the entire margin, the fringe 
longest on the hind margin; veins moderately heavy to very heavy, the 
subcosta, radius, and ba,salis always the heaviest, dark brown, and more 
or less limitedly infuscated; the subcosta not reaching the margin, 
colorless at a point near the origin of the radius; the first abscissa of 
the radius arcuate-angulate to distinctly angulate at a little more than 
90°, more or less infuscated, without a point or with a short point pro- 
jecting from the apex of the angle into the radial cell; the second 
abscissa nearly straight or slightly curved or, usually, more curved 
especially toward the tip, the vein ending distinctly back of the margin 
of the wing, the tip in many species triangularly expanded; the radial 
cell moderately broad, sometimes short, sometimes long, always open; 
areolet always present; cubitus fine, continuous, reaching the basalis 
near the mid-point, slightly infuscated at the basalis; all of the cells 
clear, or the cubital and (less often) the discoidal and (rarely) the 
radial cells with irregular, dark spots or larger, more indefinite, more 
smoky patches. 
Length 1.2 to 5.0 mm., the agamic forms averaging nearer 3.0 mm., 
the bisexual forms nearer 2.0 mm., the agamic insects in general mod- 
erately large and robust, the bisexual forms usually more slender but 
not always shorter than the corresponding agamic generations. 
MALE. — Differs from the bisexual female of the same species in 
having the compound eyes a little larger, protruding further beyond 
the cheeks; the antennae almost uniformly dark or at least darker on 
the basal segments, with one more segment than in the female, the third 
segment a little longer than in the female and with a suggestion of a 
curve; the abdomen small, elongate triangulate, moderately long petio-
