twice as long as the thorax, pale yellow, with a sparse pubescence; 

 ovipositor short. l^cgs shoit, rather slender, pale yellow, with browiiish 

 hairs; the first, third, fourth and fifth joints of the tarai short, sccond 

 Joint almost thrce times as long as the first. Wings pellucid, with a 

 very pale bluish tint, rather thickly haired; very little reflection. First 

 longitudinal vein very close to the costa, and scarcely distinguishabel 

 from it except for a short distance post the transvers vein; sccond lon- 

 gitudinal vein straight from the transverse vein, reaching the margin 

 of the wing at the apex; third longitudinal vein not forked and not 

 reaching the posterior niargin (Description drawn from dried specimen). 



Sub-genus Necrophlehia. 



Second longitudinal vein straighfc before the cross vein, reaching 

 the margin of the wing beyond its tip. Cross vein not very oblique. 

 Third longitudinal veine without an anterior brauch. Antennae in the 

 Q. 2+ 12 joinied, joints sub-cylindrical, pedicelled; two sparse verticils 

 on each Joint.

Expanse of wings 0,150X0,060 inch = 3,80X1,54 mm 

 Size of body 0,100X0,030 inch = 2,54X0,76 mm 



Antennae sordid grey, 2 + 12jointed, joints sub-cylindrical, darker than 

 and twice as long as the pedicels, two verticils to each Joint, hairs 

 somewhat sparse, light and not very long, basal joints brown, the first 

 more than twice the length of, and thicker than the second. Labium 

 and palpi faded yellowish or brownish-yellow; the three first joints of 

 the palpi of the same length, almost cylindrical, the fourth Joint one- 

 half longer than the others and more slender. Thorax brownish-red, 

 levigate, with two rows of yellowish hairs; scutellum paler villose, 

 pleurae darker than the scutellum, pale brownish red. Halteres greyish;

 thickly haired; first and second longitudinal veins paler than the costa; 

 second longitudinal vein reaching the wing margin beyond its tip; 

 cross-vein pale, but distinct; third longitudinal vein becoming paler 

 towards its end, though visible throughout its length. No anterior 

 brauch (Dry.) Hab. Middle Harbour (Skuse), Woronora (Masters).
