S. pallicornis Hartig (acc. Mayr 1872). Emerges from April to 
June in the following year (acc. Riedel 1896). 
S. varius Hartig. Emerges in April in the following spring (acc. 
Dalla Torre and Kieffer 1910). 
S. nigripes Hartig and S. flavicornis Hartig, described by Hartig 
1840 as from agama, are considered synonymous with S. pallicornis by 
Dalla Torre and Kieffer 1910).

The galls of this species are not as well represented in the 
collections as the similar galls of Cynips divisa . Agama galls 
are to be distinguished by their smaller size, more uniformly 
ellipsoidal shape, and much thinner walls. The young galls 
appear in June (acc. Mayr 1872), becoming mature by the 
end of August (acc. Connold 1908) or early in September 
(acc. Kieffer 1901). The non-parasitized galls are decidu- 
ous (acc. Kieffer 1901). The adults emerge in October and 
November (acc. Schlechtendal 1870 and Mayr 1882), more 
often in November (acc. Kieffer 1901). Further data on the 
biology of the species are not available. The alternating 
bisexual insect is not recognized, but it may be expected to 
inhabit a small cell-like gall in the buds or on the leaves of
