34, figs. M, N, P, Q; pi. 35, fig. O. 



Length of body, 2.5 to 2.9 millimeters; forewing, 2.8 to 3.3. 

 General color greenish yellow; dorsum sometimes with whitish 

 longitudinal streaks; eyes brown; antennas black at tip. Body 

 long and slender. 



Head not deflexed, not quite as broad as thorax, anterior end 

 broadly rounded both horizontally and dorsoventrally. Vertex 

 quadrate, a very little longer than broad, inclined downward 

 somewhat roundly, without prominent f oveal depressions. Gense 

 slightly swollen beneath antennal bases but not meeting over 

 f rons ; f rons visible between gense ; anterior ocellus at front end 

 of head, at end of frons. Antennae about two and one-half 

 times as long as width of head, slender. 



Thorax narrow, not arched, pronotum long; dorsulum short. 

 Legs slender, rather long ; hind tibiae with spur at base and three 

 large, black spines at apex. Forewings long and slender, three 

 times as long as broad, hyaline, transparent, sometimes slightly 

 flavous, acute at apex, with pseudovein between radius and radial 

 sector and another between radial sector and media.. 



Abdomen long and slender, tapering to narrow apex. Male 

 forceps nearly as long as anal valve, slender, arched, roundly 

 acute at apex; anal valve broadest in basal third, tapering to 

 apex. Female genital segment about one-fourth as long as ab- 

 domen; dorsal valve longer than ventral, somewhat enlarged 

 at tip, ventral valve acute. 



Luzon, Laguna Province, Los Banos (Baker), 10 specimens, 

 both sexes, taken on Sterculia foetida. 



Type locality. — FORMOSA (Matsumura). 



Several specimens from Bengal were described by me as a 

 new species, T. elongata, very closely similar to the Formosan
