line from the stigmal vein absent, the wing with an oblique 
hairless line as in Aphelinus; abdomen short, obtusely 
conical, not longer than the thorax. One ring joint. 
T' umidif ernur Girault (Type: T. pulchrurn Girault) 
Discal cilia of fore wing dense and normal but no oblique 
hairless line; no line of discal cilia leading back from the 
stigmal vein; thorax with a median sulcus; abdomen very 
long and tubular, nearly twice the length of the rest of the 
body, the very long ovipositor somewhat exserted; two 
ring-joints. Club with no terminal seta. Lathromeroides 
Girault (Type: L. lungicorpus Girault) 
(2). Marginal vein shorter, only about half the length of the 
submarginal. 
Discal cilia of fore wing dense, and in more or less regular 
lines, the oblique line from the stigmal vein present; 
abdomen short and blunt, no longer than the rest of the 
body, the ovipositor not inserted at base but distad of the 
middle or at the middle, short, not exserted. Uscana 
Girault (Type: U. semifumipennis Girault) 
b. Antennal club conspicuously enlarged and ending in a prominent 
seta; antennae 7-jointed with two ring-joints, the club 3-jointed. 
Discal cilia of fore wing not very dense and more or less irregu- 
lar or normal; marginal vein long but the stigmal practically 
absent, a mere spur from the marginal; abdomen not especially 
long. Tumidiclava Girault (Type: T. pulchrinotum Girault) 
D. Antennal club 2-jointed; ovipositor at the most barely exserted. 
a. Antennae 4-jointed, without a ring-joint. 
Discal cilia of fore wing rather dense and arranged in regular 
lines, the marginal cilia moderately short, the line of discal cilia 
from stigmal vein present; abdomen conic-ovate, as long as the 
head and thorax combined; stigmal vein short, its neck a mere 
constriction, the marginal twice its length. 
Uscanoidea Girault (Type: U. nigriventris Girault) 
b. Antennae 6-jointed, with two ring-joints. 
Discal cilia of fore wing rather sparse and dotlike, arranged in 
very regular lines, the marginal cilia moderately long, the oblique 
line of discal cilia from stigmal vein absent; abdomen short and 
blunt; stigmal vein moderate, its neck gradual, the marginal not 
twice its length. 
Uscanella Girault (Type: U. bicolor Girault) 
c. Antennae 5-jointed with one ring-joint. 
Discal cilia of fore wing dense and normal, the oblique line 
from the stigmal vein absent, the marginal cilia short; abdomen 
conic-ovate, slightly longer than the thorax; stigmal vein a mere 
small spur from the marginal, the latter sometimes swollen; club 
cylindrical. Aphelinoidea Girault (Type: A. semifuscipennis 
Girault)
