VIII. CYNIPINAE 
Plant inhabiting i.e.gall makers or guests. Thirty-seven of the 68 
• genera in the subfamily have been recognized from the area. This 
subfamily, because of the great variety of galls produced on oaks 
and roses, contains the largest number of described species and is 
the one most likely to come to the attention of the amateur. 
Key to genera 
. ( based on females ) 
1. Pronotum broad i.e. 1/6 and usually 1/5 as long in median dorsal line as 
greatest length on outer lateral margin (Fig. 9). Ventral spine 
always short (Figs. 12,15). 
Guest flies or gall makers on herbaceous plants. •••• . 2 
Pronotum narrowed in middle to 1/7 or less (Fig. 10). 
Gall makers on oaks or roses... 15 
2. Tergites II and III occupying practically the whole abdomen and either: 
a. Completely fused as in Synergjis (Fig.12), 
b. Showing a fine suture behind the short hairy tergite II (Fig. 15), 
c. Not fused but foliiform as in Euceroptres (Fig. l4)• 
These genera are inquilines in the galls of the true gall makers. • . 5 
Tergites II to VII usually showing along dorsal curvature, II longest 
and usually occupying about half the abdomen. 
Gall makers on herbaceous plants... 7 
5* Tergite I (petiole) in the form of a ring or collar which is longitudinally 
ridged (Fig 12). Face and mesopleuron striate. ... 4 
Tergite I (petiole) a short,smooth inconspicuous crescent. *••••.. 5
