Kinsey: Gall Wasp Genus Cynips 291 
Trail country of Arizona represents a distinct variety, van- 
escens . 
It is surprising to find so many oaks serving as hosts of this 
one variety, but as far as I can determine they do not effect 
the isolation of distinct varieties. In this respect hella paral- 
lels Cynips dugesi simulatrix. 
Weld found nearly full-grown galls in southern Arizona 
(Huachuca Mts.) as early as July 9, and I have fully grown 
galls dated August 16 and 22. Weld found pupae in galls at 
Hackberry (representing another variety?) on October 6. He 
found mature adults emerging from the galls as early as 
November 1 (1921), and sent me a wasp which was alive for 
almost three months (until nearly the end of January) after 
thus coming out of the gall. There were a few live adults 
left in the galls I collected in New Mexico at Alamogordo on 
December 21, and at Hillsboro on December 26 (1919), and in 
Arizona in the Santa Catalina Mts. on January 1 (1920) ; 
and these insects emerged soon after collecting. Last winter 
(1927-28 I had adults emerge from Organ Mountain material 
on January 2. Weld secured one lot of galls at Tijeras, New 
Mexico, which were only scantily parasitized, but records only 
6 gall makers left in 65 galls collected in the Chiricahuas, and 
one in fifty in Santa Rita specimens. In my own experience 
I have never found very high parasitism in this species, tho 
it might well be expected locally. 
I have examined the types of both bella and maculipennis, 
and checked them with series representing the wide range 
and hosts of the present insect. I had already concluded that 
the two names were synonyms when Weld published the 
same opinion. The types of bella and of maculipennis were 
collected at points 270 miles apart but well within the limits 
of the range of the present insect. The hosts of the types 
were not the same, but both are represented in our recent 
collections. As we now understand it, the only insect of the 
region with which bella can be confused is Cynips dugesi simu- 
latrix, but altho the galls of these two are absolutely indis- 
tinguishable, the insects are abundantly distinct.
