Kinsey: Gall Wasp Genus Cynips 
321 
TYPES. — Holotype and 3 paratype females and galls in the U.S. 
National Museum. Paratype females in the American Museum, Field 
Museum, Stanford University, Philadephia Academy, and Kinsey collec- 
tions. From Ironton, Missouri; galls October, 1917; adults May 15, 
1918; Q. stellata; Weld collector. 
The present re-descriptions are made from the holotype and seven 
of the paratypes. 
I found not fully mature galls of unica, which, however, 
were already dropping from the leaves of the post oaks, in 
southern Illinois during the second week of October (1927), 
and in southeastern Missouri and southern Ohio during the 
last week in October (1926). Live adults were in galls from 
western Missouri on November 21 (1928) . I have bred adults 
on December 12, on March 22, during the last week of March, 
and an April 10. From the galls which Weld collected in 
Missouri in October, he bred adults at Chicago on May 15, 
1918. 
The distribution data for this variety are typical for an 
Ozark cynipid. The hills of western Kentucky and southern 
Illinois, which are geologically of the same origin as the body 
of the Ozarks in Missouri and northern Arkansas, contain an 
interesting extension of the Ozark fauna. The Mississippi 
Valley in this region has a Coastal Plain fauna. Two of my 
forty insects of this species from Dexter, Missouri, represent 
unica , the other 38 being the typical Coastal Plain Carolina. 
Dexter stands at the boundary between the lowlands of the 
Mississippi and the uplands of southern Missouri. The single 
insect from my Poplar Bluff collection has an interesting com- 
bination of unica , rydbergiana, and compta characters. Weld’s 
records (1926) for unica in southern Arkansas and in Texas, 
based on galls only, probably apply to anceps, and his Florida 
record to variety mellea. I cannot interpret his Virginia 
record (Pergande collection), but I question the occurrence of 
unica that far east. 
While the areolet in all of the type series is moderately 
small to closed, one large adult which I collected at Arcadia, 
Missouri (very near the type locality), has an areolet of con- 
siderable size.
