the cross-vein closing the discal cell is situated, in one specimen at, 

 in the other somewhat before, the base of the anterior fork. All 

 have the base of the third posterior cell before that of the second 

 posterior cell. The Fijian form has considerably longer legs 

 (.42 mm.) ; the white on the knees extends equally (2 mm.) on the 

 femora and tibiae ; the apical third of the tibiae is white ; and the 

 extreme base and rather more than the apical half of the metatarsus, 

 with the remainder of the tarsal joints, white ; also, the wings are 

 longer than in T. australasiw.
