The single female, described above, was reared from leaf 
galls on Antidesma leptocladum Tul. The species is tentatively 
placed in this genus, though the wings are decidedly broader 
than in the type species, and there is a possibility that it should 
be referred to a new genus. Such action is deferred until both 
sexes can be secured. 
Lasioptera falcata sp. nov. 
Female.—Length, 1.5 millimeters. Antenne extending to near 
base of abdomen, sparsely haired, dark brown, of 24 segments,
