122 THE ENTOMOLOGIST. 
‘“‘Clypeus entire, mouth closed. Maxillary palpi 4-5, labial 
3-jointed. Vertex short, occiput seldom margined. Mesothoracic 
sutures obsolete. Abdomen sessile or subsessile, sutures distinct. 
Cubital cells 2 or 3; in the latter case the second is minute, 
subtriangular or stirrup-shaped, often imperfect; radial cell ample, 
nearly reaching the apex of the wing; exterior nervures, and 
especially the radius, more or less attenuated and obsolete ; recurrent 
nervure rejected (except in Acelius), submedian cell longer than the 
median (except in Acelius). Terebra subexserted or exserted.”’

(2) 1. Antenne 14-jointed . ; 1. Miraz. 
(1) 2. Antenne with more than 14 joints. 
(4) 3. Antenne with 20 joints - : 2. Acelius. 
(3) 4. Antenne with 18 joints. 
(6) 5. Fore wings with two cubital cells *3. Apanteles. 
(5) 6. Fore wings with three cubital cells 
(the second very small, but 
always more or less complete). 
(12) 7. Spurs of hind tibie longer than 
half the metatarsus. 
(11) 8. Abdomen narrow, slightly or not 
at all rugulose at base, hind legs 
elongate, not incrassate, second 
cubital cell often incomplete, 
though never so open as in 
Apanteles. \ 
(10) 9. Second abdominal segment with 
two nearly parallel, longitudinal 
grooved lines or furrows on the 
disc. : 4. Dvolcogaster. 
(9) 10. Second abdominal segment ‘with- 
out impressed lines. 4 : 5. Microgaster. 
(8) 11. Abdomen broad rugulose at base, 
hind legs inerassate, second 
cubital cell quite complete : 6. Hygroplitis. 
(7) 12. Spurs of hind tibie shorter than 
half the metatarsus . ‘ : 7. Microplitis. 
* In Apanteles the spurs of the hind tibie are as long as, or almost as 
long as, half the metatarsus; yet on June 11th, 1911, I captured on my 
window an insect which, while having the wings of Apanteles, has the spurs 
of the hind tibize much shorter than half the metatarsus, in fact, quite as 
short as in Microplitis. The specimen is anomalous in other respects, the 
first three abdominal segments being finely and densely rugulose, the second 
rather longer than the third.
