Fiji Islands : Viti Levu, Colo-i-Suva, 20.vi.l924 (Bryan). 



This species, which is not known to occur in Samoa, is included here because 

 of the above-mentioned points of variance with the original description and 

 figure. It has not been previously recorded from this locality in Fiji. 



4. Tr^aneoides samoaensis, sp. n. (Text-fig. 1). 



Black, densely clothed with brownish-grey dust. Interfrontalia fuscous ; 

 face with three small, dark brown, almost connected marks in depression above

 black-brown mark on each cheek near vibrissal angle ; antennae brownish- 

 yellow, third segment black except upper basal angle ; aristae and palpi fuscous 



* A careful comparison of the example from Colo-i-Suva, Viti Levu, Fiji, here discussed by 

 Mr. Malloch, with the type (J and $ of Sapromyza leucosticta Bezzi, shows conclusively that the 

 three specimens are conspecific. In all three the colour of the abdomen is the same (dark mummy- 

 brown) ; the paired spots are not on the hind margins of their respective tergites, but are nearer 

 to the hind than to the fore margins ; and the small median spot on the fore margin of the third 

 and fourth tergites in the case of the ^ type, and at least on that of the third tergite in the 

 specimen examined by Mr. Malloch, extends on to the hind margin of the preceding tergite. As 

 regards the wings, the pale longitudinal streaks which, as stated by Mr. Malloch, are present in 

 the dark areas in the marginal, submarginal and first posterior cells in the case of the specimen 

 from Colo-i-Suva, would appear to be due to individual variation, if not to immaturity as Mr. 

 Malloch suggests. As a matter of fact, the distal portion of the first posterior cell in the case of 

 Bezzi's (J type shows a trace of such a streak, which is more evident in the left wing than in the 

 right. — E. E. Austen.
