Table of the Genera of Trichogrammatini. 
A. Antennal club solid, comprising but a single joint; antennae 
6-jointed, the funicle 2-jointed*. 
B. Ovipositor not exserted, merely attaining to the end of the 
abdomen, the latter blunt. 
C. Fore wings relatively broader, the discal and marginal cilia- 
tion short; antennal funicle without minute bladder-like 
appendages; male antennae not distinctly segmented, appar¬ 
ently 4-jointed, the distal joint long, a funicle-club, and 
nodular. Trichogramma Westwood (Type: T. evanescens 
Westwood). 
CC. Fore wings relatively narrower, the marginal ciliation distad 
moderately long; antennal funicle with minute bladder-like 
appendages; male antennae distinctly 8-jointed. Tricho- 
grammatoidea Girault (Type: Chcetostriclha ncma Zehntner). 
BB. Ovipositor plainly exserted, but not for a great length; 
abdomten more or less acutely pointed. Like Trichogramma 
Westwood. Neotrichogramma Girault (Type: Trichogramma 
japonicum Ashmead). 
AA. Antennal club 3 to 5-jointed; antennae 8-jointed; the funicle 
sometimes abs'ent. 
B. Antennal club 3-jointed, the funicle 2-jointed; abdomen sub- 
cylindrical, thorax long. (Male) Calleptiles Haliday (Type: 
C. latipennis Haliday). 
BB. Antennal club 5-jointed, the funicle absent; abdomen with 
parallel sides and blunt apex; intermediate tibial spurs long 
and slender; posterior wings short. Trichogrammatella 
Girault (Type: T. tristis Girault). 
The males of Trichogramma and Neotrichogramma differ 
from the females in antennal structure, the funicle not being - dif¬ 
ferentiated from the club; the males of Trichogrammatoidea bear 
8-jointed antennae; those of Trichogrammatella are practically 
identical with the females. 
Table of the Genera of the Poropceini. 
A. Ovipositor exserted, long* 
Antennae 7-jointed, clavate, without a ring-joint, the funicle 
2-jointed, the club 3-jointed. Fore wings moderately broad, their 
marginal cilia moderately short. Submarginal veins much longer 
than the stigmal or marginal veins. Pedicel of antennae shorter 
* Funicle 1-jointed —Paratrichogramma Cinderella; see introductory.
