Kinsey: Gall Wasp Genus Cynips 
419 
Payson, Bountiful (types), Centerville, Farmington, Layton, and Willard 
(B. and H. J. Pack in Kinsey coll,). 
Probably confined to an area west of the Continental Divide. 
TYPES.-- -30 females and many galls. Holotype and paratype fe- 
males and galls in the Kinsey collection; paratype females and galls in 
the Museum of Comparative Zoology, the U.S. National Museum, and 
the American Museum of Natural History. Labelled Bountiful, Utah; 
galls September 10, 1927; insects December 18, 1927; Q. utahensis; B. 
and H. J. Pack collectors. 
This insect is best distinguished from variety undulata and 
more eastern varieties of the species by its more generally 
black color (but more rufous legs), by its slightly longer 
wings, and particularly by its rougher and even spiny, spher- 
ical gall. The gall suggests a small gall of an agamic form 
of Cynips gemmula rather than the smooth, faceted galls of 
the other varieties of hirta. Undulata is probably confined to 
an area in southern Colorado and northern New Mexico east 
of the Continental Divide. The cynipid fauna of Utah is 
usually related to but never identical with this fauna from 
the eastern side of the Rockies. 
How far packorum ranges in Utah is not determinable from 
our present insect material. Many Cynipidae in that state 
have more northern and more southern varieties whose ranges 
meet somewhere between Provo and Brigham. Most of our 
insect collections of packorum were made in this critical ter- 
ritory, but I cannot recognize two varieties in this material. 
Most of our galls of this variety were gathered early in 
September, at which time they were still young enough to be 
touched with a rosy pink, but old enough to breed with fair 
success. Adult insects emerged (out-of-doors, at Blooming- 
ton, Indiana) on November 18 and December 10 and 20. 
The type material and fine series of this variety from sev- 
eral other localities were collected by Dr. H. J. Pack, Ento- 
mologist of the Utah Agricultural Experiment Station, and 
his daughter Bessie Pack, for whom I am naming this insect. 
These collectors have sent me large series well representing 
the cynipid fauna of northeastern Utah, and they thus will 
contribute materially to our further revisions of the cynipid 
genera and our ultimate understanding of the distribution 
problems involved in that little-explored area west of the Con- 
tinental Divide.
