more brownish behind and with a few black bristly hairs about the tip ; 

 posterior cox» with abundant greyish yellow pubescence, the middle pair 

 with more numerous black bristles at the tip, and the hind pair with one 

 long bristle on the outside (usually hidden in the abundant yellow pubescence) ; 

 anterior femora with moderate inconspicuous pubescence behind and beneath 

 which may be either yellowish or blackish, and the posterior pairs with 

 moderate blackish or pale pubescence beneath near the base. Bristles on the 

 middle femora few and not conspicuous but with a few antero-ventral ones in 

 a row after the middle, while the hind femora have a conspicuous row of 

 about seven black antero-ventral bristles and two less distinct anteiior ones 

 near the tip ; front tibiae with dorsal and postero-ventral rows of easily 

 abraded black spicules ; middle tibiae with four rows of small but distinct 

 bristles and with two or thi*ee fair-sized apical spines besides some rather 

 shorter ones ; hind tibiae with smaller and more numerous black bristles which 

 are almost lost among the sloping black scales, and with a circlet of 

 apical spines. Scales on the front femora both in front and behind pale 

 and conspicuous though not crowded ; middle femora with similar but more 

 crowded scales almost all over ; hind femora with still more crowded pale 

 scales all over except on the apical dorsal and anterior surfaces, while closely 

 adherent black scales occur on this apical dorsal surface ; pale scales also 

 occur sparingly behind the basal half of the posterior tibiae, and sometimes 

 these pale scales are much more extended and become fairly consjiicuous on 

 the front part of the hind tibial ; closely adherent black scales occur 

 sparingly on the upper side of the front tibiae near the base and in 

 greater quantity on the middle tibiae, but on the hind tibia? besides dense 

 and adherent black scales there are numerous long splayed out sloping black 

 scales which give the tibia? the appearance of being considerably incrassated. 

 Pulvilli absent ; front tarsi with short delicate almost erect pubescence 

 above and beneath ; front claws shorter than the others. 



Wings shimmering glassy, but sometimes slightly greyish, with the base 

 and foremargin conspicuously yellowish brown from the costa to the subcostal 

 vein, while the space below that is occasionally faintly brownish down to the 

 discal vein ; prsemrca slightly margined ^^^th brown, and all these anterior veins 

 and the stem of the postical vein broAvoi while the other veins are black ; 

 the absolute root of the wing brownish black ; the broadened base of the 

 costa black or brownish black with a densely spinose foremargin, and bearing 

 dense small black scales amongst which are some pale ones near the base 

 but well away from the actual foremargin, but these pale scales vary very 

 much in extent and are sometimes restricted quite to the inner base, but 

 when more considerably extended over the widened base of the costa they 

 may be replaced at the inner base by some inconspicuous ferruginous scales ; 

 the patch of silvery (or yellow) scales on the wing-base has been described 

 before when dealing with the thorax, but between it and the spinose fore- 

 margin there is occasionally (but rarely) a black finger-like spine, and even 

 when this does occur it is usually very small and I feel convinced is 

 usually quite absent ; discal cross-vein often exactly opposite the base 

 of the cubital vein, but sometimes after and occasionally just before it ; 

 base of the radial vein often rectangular and sometimes thi'owing out a 

 short recurrent veinlet ; looji of the radial vein before its tip rather deep ; 

 the piece of the upper branch of the postical fork which forms the lower 

 mai'gin of the discal cell about as long as, or slightly shorter than, the 

 basal line of the discal cell ; the ambient vein obviously black, and becoming 

 rather conspicuous round the alula j alula? bearing some greyish white 

 scales on the inner two-thirds of their margin. Squamae brownish yellow 

 with a rather darker margin but l)lackened at the root ; fringe rather long, 

 very dense, scale-like and coarse, pale dull yellow to orange. Halteres small, 

 pale orange with darker orange stems. 



9. Rather like the male, but the pubescence less abundant and each of the 

 second, third, and fourth segments of the abdomen bearing a band of jiale 

 scales. 



Frons at the top about one-eighth the width of the head and steadily 

 widening to fully one-third its width at the antenna?, black, moderately
