marginal cells long and large. Hind wings about half B8 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- 

 ward than forward; antennse a 

 little shorter. Forewings rela- 

 tively a little broader and mar- 

 ginal cells shorter and broader; ^ 2 Mwrniou mwwtomf* nr — 

 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
