The funicle of the antenna is present. 
A, Ovipositor not exserted nor prominent, nor are its valves. 
a. Antennae 9-jointed with two ring-joints, the club 3-jointed, two 
funicle joints. 
(1) . Marginal vein long, over half the length of the submarginal, 
very much longer than the stignmal. 
Stigmal vein neckless; funicle joints wider than long. 
Fore wings variable, the discal ciliation normal to 
moderately sparse and arranged in lines, the marginal 
cilia moderate; oblique line of cilia from stigmal vein 
may be present, usually absent. Pedicel larger than 
the funicle. Abdomen conic-ovate. Abbella Girault 
(Type: A. subflava Girault) 
Stigmal vein with a distinct neck; funicle joints longer than 
wide. 
Fore wings with dense discal cilia, the marginal cilia 
short; oblique line of cilia always present. Thorax 
with a median sulcus. Ittys Girault (Type: Tricho- 
gramma acuminatum Ashmead) 
(2) . Marginal vein short, not as long as the stigmal which has 
a distinct neck; marginal vein not much longer than wide. 
Fore wings with moderately short marginal cilia, their 
discal cilia dense but with three or four lines distinctly 
regular; oblique line of cilia from stigmal vein absent; 
thorax with a more or less distinct median sulcus. 
Neobrachista Girault (Type: N. fasciata Girault) 
b. Antennae 8-jointed, the club 3-jointed. 
(1) . Two ring-joints, one funicle joint. 
Fore wdngs broad, distad with long marginal cilia; ovi- 
positor only half the length of the abdomen, not exserted. 
Brachysticha Mayr (Type: Brachystira pungens Mayr) 
Fore wings with short marginal fringes; like Ufens. Sub- 
genus Parufens Girault (Type: P. argentipes Girault) 
(2) . One ring-joint, two funicle joints. Marginal vein of fore 
wing only slightly longer than stigmal. 
Funicle obliquely divided and apparently twisted, much 
larger than the pedicel. 
Abdomen short, stout, obliquely truncate at apex, the 
ovipositor inserted near the middle; fore wings short 
and broad, oblately rounded at apex, the discal cilia- 
tion with some peculiarly distinct lines, dense, the 
marginal fringes very short; neck of stigmal vein not 
slender; male antennae with one more joint, cylindrical.
