TABLE OF GENERA 
a. Subcostal vein {Sc , ) long, reaching at least one- fourth ilie length of the 
iving and usually ending in the casta. 
b. -ff^-i-j and R^-ys both arise at the R-M crossvein (PI. 3, Fig. 6) . 
bb. R^j^j and R_f^s separate distad of the crossvein (PI. 3, Fig. 7) . 
aa. Subcostal vein {Sc r) very short. 
h'. The media forks distad of the base of R^^.j (PI. 3, Fig. 8) . 
bb. The media forks proximad of the base of R^ys (PI. 3, Fig. 9) .

Characters. — Head spherical, flattened in front; e_ves reniform. somewhat approximated; 
ocelli three, arranged in a triangle on the front, the anterior one smaller; palpi four segm.ented, first 
joint ver}' small, cylindrical, the second enlarged, the last two cylindrical, the last one longest; face 
bare: antennas projecting forward, cylindrical, 2-|-i5 jointed, the first two cupuliform, the flagellar joints 
broader than high, almost annular, the last very small. Thorax ovate; scutellum small, nearly semicir- 
cular in outline; metanotum somewhat arched. Abdomen seven segmented, that of the male almost 
cylindrical, of the female laterall)' compressed. Legs quite slender; the femora slightly thickened, the 
tibiae somewhat broadened, with short and slender spurs; the fore tibia; without, the middle and hind 
pairs with one row bf ver}' small and slender lateral setae. Wing large, with broad base, microscopically 
setulose, folded flat over the back when at rest, longer than the abdomen. Subcosta simple, i, e. not 
connected with Rj hy Scs , ending near the middle of the anterior margin, R2-1-3 arises at the R-M cross- 
vein. R4-1-5 ending near the tip of the wing, the costa prolonged a little be^'ond it, the media arises appa- 
rently at the M-Cu crossvein though in some species there is an indication of a vein which bisects the 
basal cell and may represent the basal section of the media; cubitus forks slightl}' proximad of the M-Cu 
crossvein; anal vein ends in the margin of the wing (PI. 3, Fig. 6).
