wings broadly convex. Female genital segment very short, 

 much shorter than abdomen, dorsal valve a little longer than 

 ventral, both subacute. 



Type locality. — Fiji Islands, Rewa (Muir), March, 1906, 

 3 males and 2 females. 



Singapore (Baker), 1 pair. Amboina (Muir), 1 female. 

 Pemalonga (Leeuwen-Reijnvaavi) , 1 male and 1 female, on Eu- 

 genia malaccensis, April 10, 1912. Ceylon, Peradeniya (A. 

 Rutherford) , 9 males and females from galls on leaves of Eugenia 

 malaccensis, May 12, 1913 (described as Trioza eugenise). 



This appears to be a widely distributed species in the South 

 Pacific in tropical Asia, making galls on Eugenia malaccensis 

 (known also as Jambosa domestica) . The name Trioza euge- 

 nise, applied to some newly emerged Ceylonese representatives 

 of this species, was preoccupied by an Australian species named 

 by Froggatt, but subsequent study shows the species to belong to 

 Megatrioza and furthermore to be synonymous with Kirkaldy's 

 T. vitiensis. The Fiji specimens before me bear no identifica- 

 tion mark indicating that they were examined by Kirkaldy, but 

 they agree well with his description of T. vitiensis and probably 

 are paratypes in as much as the date of collection and locality 

 are identical in both lots.
