EMPIDIDAE AND PIPUNCULIDAE.

also very short, ending very little beyond the middle of the wing, with its short 

 curved prefurca arising from the subcostal vein near the end of the latter. The 

 anal angle of the wing is not at all developed, and the last section of the postical 

 vein is distinctly curved downwards towards the wing margin at the tip. 



5. Drapetis savaiiensis, sp. n. (Text-fig. 2). 



Frons shining black, narrowing towards front where it is almost as wide 

 as second antennal joint. Eyes microscopically pubescent. Occiput clothed 

 with brownish dust, but having a shining postocular ring, narrow above and 

 below, but much widened in middle because of concavity of eye-margin there. 

 Two pairs of long ocellar bristles, front pair parallel, hind pair divergent ; only 

 fine dark hairs on vertex and back of head. Antennae with third joint slightly 

 longer than first two joints together, and in addition having its upper angle 

 prolonged so that it looks like base of arista ; from end of this prolongation 

 proceeds at a slight angle the long microscopically pubescent arista. Palpi 

 dark, small and ovate. 



Thorax black, shining and apparently bare on disc, except for postalar calli 

 and scutellum, which are clothed with brownish dust. Prothorax and upper 

 part of pleurae also clothed with brownish dust, leaving lower part of sterno- and 

 hypopleurae shining. An upcurved humeral bristle ; a row of 3-4 bristles 

 above root of wing, of which front two are stronger and probably represent 

 notopleural bristles ; a small postalar, and a pair of strong apical scutellar 

 bristles placed close together. 



Abdomen dull brownish-yellow and apparently not much chitinized, except 

 for hypopygium, which is blacker. Pubescence short and dark, longer on 

 hind margin of last tergite and on hypopygium. 



Legs, including coxae and trochanters, yellow, with apical half of hind femora 

 blackish, and tibiae, especially hind pair towards tips, sometimes rather tawny ; 

 last joint of all tarsi brownish. Front coxae mth a few projecting small black 

 spines, including a stronger one at upper outer corner. Front femora with a 

 short yellow bristle or two and a small black spine at base beneath, a short 

 anteroventral row of tiny black points about base, and a posteroventral row 

 of short dark bristles on apical half. Front tibiae with two short rows of tiny 

 black points, anteroventrally about middle and posteroventrally towards tip. 

 (Other legs in case of type too obscured by gum to describe.)
