Macromastix pallida Hutton. 
Macromastix pallida Hutton, Trans. N.Z. Inst., vol. 32, p. 31, 1900. 
Hutton's brief description omits mention of what is perhaps the 
most characteristic feature of the species, the length and slenderness of 
abdomen when compared with obher species of the genus. e first 
antennal joint is also unusually short, and the penis is much stouter than 
in any other species which I have examined, though in other respects the 
structure of the hypopygium is typical of "Macromastiz. There is some 
variation in the position of the radial cross-vein, which in some speci- 
mens is.placed exactly at or even immediately before the base of К 
The halteres are unusually long, and, like the antennae and legs, are light- 
brownish.
