marginal cells long and large. Hind wings about half a,s long 
as forewings. 
Male forceps long, acuminate, curved, acutely pointed, hairy. 
Anal valve a little longer than forceps, broadest at base, some- 
what triangular in outline, about twice as long as basal width. 
Female genital segment about half as long as abdomen, dorsal 
valve a little longer than ventral, both subacute. Ovipositor 
very slender and acute, styliform, exserted. 
Singapore (Baker) , 1 pair. Luzon, Laguna Province, Mount 
Maquiling (Baker) , 1 female. 
In wing venation this species is apparently allied closely to 
M. vitiensis. 
Megatrioza asiatica Crawford. 
Trioza asiatica Crawford, Philip. Journ. Sci. § D 10 (1915) 266. 
This species must be referred to Megatrioza, although the 
basal spur of the hind tibia is almost wanting and the subapical 
spine is very near the apex. The large anterior metacoxal spurs 
and the shape and venation of the forewings indicate a close 
alliance to Megatrioza species. The hind wings in this species 
are remarkable in being reduced to mere stubs that are not at 
all functional. 
This and the following species (M. magnicauda) bear a closer 
similarity to the American T. diospyri Ashmead than any other 
known species, indicating a probable relationship. 
Mindanao, Davao (Baker), 1 pair. 
Megatrioza magnicauda sp. nov. Text fig. 2. 
Length of body, 2 millimeters; forewing, 4. General color 
glossy black; antennae yellowish, black at tip; legs black, hind 
tibiae yellowish or whitish on basal two-thirds; forewings clear, 
a black spot in clavus. 
Head and thorax similar to M. asiatica, to which this species 
is closely related, but distinctly narrower; genal cones a little 
shorter and directed more down- 
hind wings reaching to end of 
abdomen, while in the related species they scarcely reach half 
way there. 
Male forceps similar, but anal valve immense, reaching caudad 
beyond forceps, rectangular in outline with anal opening much 
ward than forward; antennas a 
little shorter. Forewings rela- 
tively a little broader and mar- 
ginal cells shorter and broader;
