ones on outer side ; posterior tibiae with bristles on outer and 

 Milder sides. Tarsi with a few bristly hairs below. Wings dis- 

 tinctly pale yellow, very iridescent, quite unmarked ; venation 

 exactly as in S. ceylonica, and the costa with a distinct fringe of 

 short bristly pale hairs, which are nearly absent at the base, both 

 on front and hind margins. Halteres pale dirty yellow.

 GENOTYPE, L. singular is, Skuse ; by original designation. 



" Two submarginal cells, the first verv short, sub-triangular ; 

 four posterior cells ; no marginal cross-vein, but inner marginal 

 cell closed by first longitudinal vein, which ends at inner end of 

 first submarginal cell ; small cross-vein situated some distance 

 before inner end of second submarginal cell ; praefurca 

 originating beyond the middle of the wing ; discal cell closed, 

 elongated, its inner half cuneate, and its inner end situated 

 before origin of prsefurca ; wings glabrous. Antennae 16-jointed, 

 short. Feet long, slender ; tibiae with spurs ; ungues small, 

 smooth ; empodia indistinct. Male forceps with two horny 

 appendages ; an outer linear one, and a longer somewhat hooked 

 inner appendage ; also five long, horny, needle-like processes of 

 the internal apparatus. Rostrum nearly half the length of the 

 head ; palpi of moderate length, the first joint apparently 

 slightly the longest, the last three rather thicker, equal. The 

 antennas little longer (if any) than the head ; joints of scapus 

 somewhat thick, subcylindrical, the first rather longer than the 

 second ; flagellar joints subcylindrical, with very short hairs. 

 Eyes contiguous above, and almost so on the underside. 

 Collare inconspicuous. Legs clothed with only a microscopic 

 pubescence. Wings very cuneiformly narrowed towards the base, 

 with only a slight anal angle ; covered with microscopic dots, 

 visible only under a high power ; the veins at apical end of wings 

 densely beset with minute hairs ; stigma narrow, elongate, 

 enveloping terminal portion of first longitudinal vein. The tip 

 of auxiliary vein is opposite the end .of the prsefurca and the 

 small cross- vein ; the subcostal cross-vein at its tip ; praefurca 

 very short, originating at an angle ; the first longitudinal gently 

 arcuated into the second longitudinal, joining at the base of its 

 fork ; the first submarginal cell is very short ; the anterior branch 

 of the second longitudinal fork about half the length of the 

 posterior, the latter converges towards the tip of the third
