Kinsey : Gall Wasp Genus Cynips 
355 
RANGE. — Utah: Bountiful (types; B. and H. J. Pack in Kinsey 
coll.). Farmington, Santaquin, and Layton (B. and H. J. Pack in 
Kinsey coll.). 
Probably restricted to an area in more northeastern Utah. Fig- 
ure 59. 
TYPES. — 149 females and many galls. Holotype and paratype 
females and galls in the Kinsey collection. Paratype females and galls 
at the American Museum of Natural History, the U.S. National 
Museum, the Museum of Comparative Zoology, the Utah Agricultural 
College, the Stanford University museum, the California Academy of 
Science, and the Field Museum. Labelled Bountiful, Utah; galls Sep- 
tember 10, 1927; females December 5 and 23, 1927; Q. utahensis; B. and 
H. J. Pack collectors. 
This is an apparently common insect in the mountains of 
northeastern Utah. Its closest relatives are alaria , which 
occurs in southern Colorado and northern New Mexico east of 
the Continental Divide, and the variety villosa , which ranges 
from Kansas into New York State. Calvescens is imme- 
diately distinguished by the large, naked area on the abdomen, 
the more eastern insects having the sides of their abdomens 
entirely hairy. The name calvescens (becoming bald) empha- 
sizes the striking appearance of the new variety. This Utah 
insect also has a distinctly longer wing and averages shorter 
in body length than either of the other varieties. 
The Cynipidae of Utah, as far as I have studied them, are 
never the same as those of Colorado, and the present species 
serves to illustrate how distinct these faunas may be. 
We are indebted to Dr. H. J. Pack and his daughter, Bessie 
Pack, for all the material we have of this insect. The galls 
collected early in September (1927) seemed fully mature. Out- 
of-doors at Bloomington, Indiana, I bred 66 adults by Decem- 
ber 5, another 76 by December 13, and another 9 at some later 
date (all in 1927).
