 scarcely longer than wide, the second with a long-spined process 

 outwardly - 2 



Basal joint of hind tarsi usually shorter than joints 2 to 5 united, or never much 

 longer; abdomen not or very little longer than the head and thorax 

 united. 



Second and third abdominal segments in female closely united and occupying 

 the whole or nearly the whole surface of the abdomen, very rarely 

 showing an indistinct dividing suture between; if the suture is pres- 

 ent, it is very oblique and the segment dorsally is fully two-thirds 

 the length of the abdomen; male sometimes with the second and 

 third abdominal segments subequal, but these segments occupy 

 most of the surface of abdomen; venter more or less completely 

 covered basally Subfamily I. synergin.e. 



Second and third abdominal segments, in female and male, well separated and 

 rarely occupying nuich more than half the whole surface of abdo- 

 men; segment 3 in male never longer than half the length of the 

 first dorsally, the second segment being usually as long as all the 

 following segments united; venter always visible. 



Subfamily II. cynipin^. 



2. A]:)domen very strongly compressed, cultriform, and much longer than the head

table of families. 



Hind wings exceedingly narrow, linear, peduncle at base; ovipositor issuing from 

 beneath just anterior to tip of abdomen; antennae without a ring- 

 joint, the scape rather small, short, compressed 12 



Hind wings never very narrow, nor linear, not pedunculate at base; ovipositor 

 issuing far anterior to the tip of abdomen; antennae elbowed, with 

 1, 2, or 3 ring-joints, very rarely without, the scape large and rather 

 long. 

 Axillfe triangularly jiroduced or advanced forward into the basal region of 

 the scapula^ their base or anterior margin on or in advance of an 

 imaginary line drawn from tegula to tegula; anterior tibial spur 

 most frequently small or weak; tarsi 3-4-jointed, rarely 5-jointed or 



heteromerous 10 



Axillae normal, or at least never produced forward into the basal region of 

 the seapuke, their base or anterior margin straight and always back 

 of an imaginary line drawn from tegula to tegula; anterior tibial 

 spur large and strong; tarsi 5-jointed (rarely 4-jointed, or 3 or 4 

 jointed in some wingless males) 3 



3. Head in female oblong, with a deep, broad longitudinal furrow above, the occip- 



ital margin sujieriorly, usually with a small recurved tubercle or 

 spine at its middle; mandibles or palpi most frequently furnished
