terior parallel lines more distinct toward the pronotum; the 
smooth area on the scutellum is smaller, more distinct in outline, 
not so rugose, and connected to the mesonotum by a narrower 
isthmus; the transverse, rugose band across the mesopleura is 
considerably narrower and more distinct in outline: the rufous 
area on the abdomen, dorso-basally, is smaller and darker; the 
areolet is a little larger. 
Male. — Differs from the male of variety utahensis only in 
varietal characters as described for the female. 
Gall. — Practically the same as the gall of utahensis. 
Range. — Utah: Provo, Brigham (Kinsey). Probably con- 
fined to more northern Utah and adjacent Idaho. 
Types. — A great many females, about forty galls. Holotype 
female, paratype females, males, and galls at The American 
Museum of Natural History; paratype adults and galls at the 
Museum of Comparative Zoology, the U. S. National Museum, 
the Philadelphia Academy, Stanford University, the California 
Academy, and the Kinsey collection. Labelled Provo, Utah; 
April 18, 1920; Kinsey collector. 
The variety utahensis is found at Price, Utah, while variety 
angustior is found at Provo; the two localities are separated by 
only sixty miles, but Price is a thousand feet higher in elevation. 
The two varieties are so closely related that they have heretofore 
been considered the same; the relationship is so close that they 
are hardly separable on any one character, but they are easily 
distinguished by a combination of characters. The most dis- 
tinctive characters are the transverse rugose band on the meso- 
pleura, the size of the areolet, and the smooth area and isthmus 
on the scutellum. 
It is interesting to note that all other Cynipidse known from 
Utah have two very closely related varieties in a more northern 
and more southern faunal area; utah^nesis has been the only excep- 
tion, but now that angustior has been described, the rule holds 
without exception. Plana, another variety of the same species 
from southeastern Oregon, is almost as closely related to utahen- 
sis and angustior. 
Dr. Kinsey of the Zoology Department of Indiana Univ- 
ersity has supervised this study.
