Kinsey : Gall Wasp Genus Cynips

situation, nevertheless, warrants the conclusion that a consid- 
eration of the insect morphology alone would have led to a 
highly artificial classification. 
The bisexual forms are known for four of the varieties rep- 
resenting three of the species ( folii , longiventris, and divisa) 
of European Cynips. The agamic galls appear in Central 
Europe in late June, maturing in August, the insects trans- 
forming into adults in September or October but delaying 
emergence until late in October, November, December, or 
warmer days in later winter. The eggs of these agamic fe- 
males are layed in buds, the bisexual galls appearing in April 
or May in the adventitious buds on older branches, or on 
younger shoots, or on the tips of the leaves, depending on the 
place of oviposition of the agamic mother. In the uniformity 
of these four life histories we have an evidence of relation- 
ships which is stronger than that furnished by the few mor- 
phologic characters available for delimiting the subgenus; 
and we may confidently predict that the bisexual generations 
of the other varieties, with the possible exception of C. corni- 
fex, will prove nearly identical with the bisexual forms al- 
ready known. There is, however, a possibility that some of 
the most southern varieties may have only a single, agamic 
generation in a year, without alternation of generations — a 
condition evidently existing among some of our more southern 
American Cynipidae. 
In addition to the above-mentioned, bisexual Cynips, there 
is another, Cynips schlechtendali Kieifer, that seems unrecog- 
nizable to me at this time. The data for this insect are given 
directly below, instead of in place with the known species of 
Cynips, for schlechtendali is not more than a bisexual form of 
agama or divisa (the only Central European Cynips for which 
bisexual forms are not known) , if indeed it is not a synonym 
of one of the other bisexual forms.
