Kinsey : Gall Wasp Genus Cynips 
228 
This is a northern Pacific Coast subgenus of Cynips , the 
only one represented north of the California-Oregon boundary. 
Of the four species in the group, all are known from the 
Mendocino-Lake County area, only one ( multipunctata ) is 
found in the Central Valley, and only one (mirabilis) is known 
to extend north of California. There are no records of any 
species occurring south of Kern County, in what is technically 
Southern California, even tho Q. dumosa , the host of one of 
the species in the north, is the white oak of lower elevations 
in Southern California. 
FIG. 30. KNOWN RANGE, SUBGENUS BESBICUS 
Shading and figures indicate number of species known from each area. 
In numerous respects, including the 14-15 segmented an- 
tennae, the remarkably large hypopygial spine, and the en- 
tirely hairy abdomen, Besbicus is distinct from any other 
group of Cynips; and yet it agrees with Cynips folii (the geno- 
type) in many respects. 
Besbicus is known from but 3 species, representing 8 vari- 
eties. Two of these were described in 1911, one in 1922, one 
in 1926, and the remaining four in the present paper. The 
subgenus is of such recent discovery that our knowledge of it 
may be quite incomplete. 
The described species represent two groups. The insects 
of heldae and multipunctata are not distinguishable, and altho
