Kinsey: Gall Wasp Genus Cynips 
417 
rufous basally; lateral lines indicated by smoother areas; wings 0.23 of 
the body in length; body 2.5 to 3.0 mm. in length. Figures 379, 423. 
GALL. — Of moderate size, more or less ellipsoid, the faceted sur- 
face fairly smooth in appearance; on leaves of Quercus Gambelii and 
its varieties (NOT on Q. undulata!) . 
RANGE. — Colorado: Manitou (types, Gillette coll.). 
New Mexico: Kingston (galls, Kinsey coll.). 
Probably confined to Q. Gambelii and its varieties, in a Southern 
Rocky Mountain area of southern Colorado and more northern New 
Mexico. Figure 70. 
TYPES. — 19 females and numerous galls. Holotype and 4 para- 
type females and galls in the U.S. National Museum; paratype females 
and galls in the American Museum of Natural History and in the 
Illinois Natural History Survey collections. 
The present re-descriptions are based on all this type material, the 
holotype and 5 of the paratypes being compared directly with paratypes 
of macrocarpae (= macrescens ) . 
There appear to be no data on this insect beyond Gillette’s 
record of the type collection. His galls, collected on June 30, 
contained mature adults that ran about when cut out. It is 
difficult to understand summer maturity, in the light of the 
data for related varieties of the species, unless these were 
survivors of the previous year’s growth that had failed for 
some reason to emerge in the late fall or the ( winter. Gil- 
lette stated that from June 30 to November 19 none of the 
insects emerged, tho a number were cut out of the galls. His 
further statement that the galls were kept in a warm room 
after the last of September may offer one more explanation 
of the failure to obtain normal emergence. 
I have a single gall from Kingston, New Mexico, which 
might well represent the present variety. The insect had 
emerged when I collected this gall on December 27 (1919). 
We must await insect material before we can be certain that 
undulata extends as far south as Kingston. West of the 
Rockies, in Utah, there occurs variety packorum with its dis- 
tinctly blunt-spiny and spherical gall. True undulata does 
not occur east of Colorado. 
Variety undulata , so named because of Gillette’s confusion 
of the names of the Rocky Mountain oaks, really occurs on 
Quercus Gambelii and the closely related varieties or species 
of oaks. Fragments of leaves with the type material confirm 
our interpretation of the host.
