Kinsey : Gall Wasp Genus Cynips 
349 
RANGE.— In the Southwestern United States from Arizona and 
Utah into West Texas and southern Colorado, eastward in the Middle 
West to Indiana and New York State; also to be expected southward 
into Mexico. Figure 59. 
The very attractive galls of this species are to be found over 
a wide area in the Southwest, but they are rarely common. 
They appear early in the summer, full-sized galls developing 
by late August. The adults mature sometime in the fall but 
do not emerge until November, December, or early January. 
One of the varieties, apache , has shortened wings, but its 
gall is indistinguishable from that of the long-winged acras- 
piformis. The long-winged variety from West Texas, namely 
expositor , produces a distinctive gall which more closely re- 
sembles the work of the short-winged variety alaria. Thus 
the unity of this interesting assemblage of short-winged and 
long-winged insects is assured. The contiguous distributional 
areas of the short-winged and long-winged insects in the South- 
west further justify our opinion that these superficially diverse 
forms are no more than geographic segregates of a single an- 
cestral stock. 
Cynips villosa is closely related to C. nubila. A study of 
the comparative descriptions of the two shows surprisingly 
few differences outside of the coloration, the wider pubescence 
of the abdomen, and the more elongate hypopygial spine of 
nubila. The two clouded patches are distinctly separate in 
the wings of acraspiformis, while they are more or less fused in 
nubila . With the insects so similar, it is interesting to find 
that the galls are also similar, the stiffer spines of acraspi- 
formis being replaced by long, flexuous, hair-like spines in 
nubila.

FEMALE. — Entire body, including the antennae and legs (except 
the coxae) piceous to black, light brownish piceous in places; head 
rather narrower than the thorax, evenly shagreened; thorax quite large 
and robust, about half again as long as wide; parapsidal grooves more 
or less complete tho indefinite anteriorly; scutellum moderately rugose,
