Antennal club ending in a spinelike seta; ovipositor as 
long as the abdomen, the latter as long as the rest of the 
body; no oblique line of discal cilia from the stigmal vein; 
marginal cilia of fore wing short, much less than a fourth 
the greatest wing width. Fore wings moderately broad. 
Body long. Lathromerella Girault (Type: L. fusciata 
Girault) 
Antennal club not terminating in a spine-like seta; ovi- 
positor the same but the abdomen short and acute, the 
body short and compact; an oblique line of discal cilia 
from the stigmal vein; marginal cilia of fore wing mod- 
erate in length, about a fourth or more the greatest wing 
width. Fore wings narrow. Ovipositor somewhat ex- 
serted. Lathromeroidea Girault (Type: L. nigra Girault) 
(2). Antennae 8-jointed, with one ring-joint, marginal vein short. 
Antennal club clothed with long, stiff, spinelike seta and 
fusiform-acuminate in shape, the terminal joint long and 
acuminate, the proximal joints transverse; fore wings 
as in Ufens as is also the body. Haeckeliania Girault 
(Type: H. haeckeli Girault) 
B. Antennal club 4-jointed; abdomen long. 
Antennae with a minute ring-joint; marginal vein moderately long, 
normal. 
Antennae 7-jointed, club slightly enlarged; marginal cilia of fore 
wing short, the marginal vein about one and a half times the length 
of the stigmal, the latter with a very short neck; discal cilia rather 
dense, not in very distinct regular lines; no oblique line of discal 
cilia from the stigmal vein. 
Lathromeris Foerster (Type: L. scutellaris Foesrter) 
Antennae without a ring-joint; marginal vein moderately long but 
clavate, gradually thickening apically. 
Antennae 6-jointed; marginal cilia of fore wing very short, the 
discal cilia arranged in peculiarly distinct lines and there is an 
oblique line of it leading back from the stigmal vein, the latter short, 
thick, neckless and only half the length of the marginal. 
Zaga Girault (Type: Z. latipemiis Girault) 
C. Antennal club 3-jointed; ovipositor at the most but slightly exserted. 
a. Antennal club not conspicuously enlarged, only slightly so; an- 
tennae 6- to 7-jointed with one or two ring-joints. 
(1). Marginal vein long, as long or nearly, as the submarginal. 
Discal cilia of fore wing sparse and in more or less regular 
lines, the oblique line from the stigmal vein usually pres- 
ent; abdomen conic-ovate, longer than the rest of the 
body, the ovipositor inserted at base and slightly exserted 
at tip. One ring-joint. Pterygogramma Perkins (Type: 
P. acuminatum Perkins) 
Discal cilia of fore wing dense and normal, the oblique
