than the flagellar joints, both densely scaled ; flagellar joints short, 
cylindrical, verticillate-pilose at the base, separated by short 
pedicels, the terminal joint longer than the rest, coniform. Thorax 
oblong, arched ; prothoracic lobe scarcely noticeable ; scutellum 
small ; metathorax steep. Halteres small. Abdomen almost 
cylindrical, tapering towards the extremity, with eight segments. 
Legs long, slender, the fore pair the shortest ; minutely spinulose ; 
metatarsal joint very long, in the hind-legs longer than the tibim ; 
ungues small, acute. Wings longer than the abdomen, narrow, 
elongate, densely ciliated, the veins very densely covered with 
more or less elliptical scales which completely cover the 
wings 3 incumbent in repose. Humeral cross-vein and sub- 
costal cross-vein present, the latter situated much before the 
middle of the auxiliary vein. Marginal cross-vein wanting. 
Second longitudinal vein starting from the first longitudinal 
vein a short distance beyond the sub-costal cross-vein, ter- 
minating in a long narrow fork the branches of which run 
parallel. Third longitudinal vein bent sharply downwards at its 
base then running perfectly straight to the apex of the wing, 
originating at a point a little nearer to the base of the fork of the 
second longitudinal than to the origin of the latter. Middle 
cross-vein situated close to the base of the third longitudinal vein. 
Fourth longitudinal vein terminating in a fork about equal in 
width and length to that of the second longitudinal vein, its base 
lying before that of the latter. Posterior cross-vein situated 
before the middle cross-vein and and about opposite the tip of 
the sixth longitudinal vein (PI. XL., fig. 4).
