but sparser pubescence, and all tlie rest of the pleurae quite bare. Scutellum 

 brownisli with the tip almost blackish ; pubescence longer, more erect, and 

 paler than on the thorax. 



_ Abdomen black and orange, broad at the base and tapering almost to a 

 point, rather longer than the thorax and scutellum together ; the black colour 

 includes the basal segment, a triangular spot against the middle of the base 

 and a spot on each side of the second segment, and a largish middle spot and 

 distinct side-spots on the third and fourth segments : the fifth segment is also 

 black except at the basal corners and hindmargin, while all the sixth and 

 -seventh segments are black. Genitalia long ancl stout, all orange except at 

 the tip. Pubescence universal, depressed, rather abundant and fairly con- 

 spicuous _ on especially the hindmargins, pale orange with traces of a few 

 black hairs across the disc and about the middle of the base of some segments 

 and especially on the second and third segments. Belly with the very short 

 basal segment black, but otherwise mainly yellow with a transverse black 

 spot on the middle of the base of the second segment and on the disc of 

 each of the next three segments, and with spots outside these and with still 

 more conspicuous sidemarginal spots ; on the third segment these spots may 

 coalesce or the side-spots may be faint, and on the fourth and fifth segments 

 the black spots do coalesce ; sixth segment all orange ; pubescence thinner 

 and more erect than on the doi'sal sicle. 



Legs mainly orange, but the coxaj and trochanters greyish black, and the 

 front femora mainly blackish or brownish black except on the apical 

 quarter, while the posterior femora are usually nearly ,, 



all brownish orange but partly blackened beneath on S^'^^k 



the basal half of the middle pair; the coloring of the 

 femora however varies extensively, even to the greater 

 part of the four posterior femora being almost 

 blackened ; tarsi obscured after the base ; front tarsi 

 about one and half times as long as, middle tarsi about 

 equal to, and the hind tarsi shorter than, their tibiae ; 

 hind tibi« stout. Pubescence on the coxa3 and behind 

 the anterior femora rather long and mostly black, but 

 pale on the front femora near the base and sometimes 

 more pale beneath but black in front; middle femora 

 with rather similar pubescence ; the rest of the clothing 

 of the legs mainly composed of tiny black bristles which 

 become rather longer on parts of 'the hind femora and 

 tibiae; front tarsi with the "touch-hairs" very few, p^_, ^ , ^.^ 



short, and inconspicuous; middle tibite with two spurs Left front tarsus?" x"o 

 of which the _ front one is distinctly the longer, but the 

 hind tibiie with two almost equal spurs. Pulvilli on the front legs with the 

 outer pulvillus reduced in size and the outer claw enlarged and twisted over 

 it (fig. 190), but the middle imlvillus enlarged; posterior claws and pulvilli 

 normal and not short. 



Wings mottled blackish and hyaline, but with the mediastinal cell 

 brownish ; the blackish markings form three or four irregular and incomplete 

 bands across the wings, of which the most conspicuous is the one which 

 extends across the middle of the wing and forms a large blotch under the 

 stigma extending fairly distinctly to the fork of the postical vein or even to 

 the end of the postical vein. Stigma brownish black, but leaving the tip 

 of the marginal cell conspicuously pale yellowish brown. Squamae (alar) 

 obscure whitish with a thick pale yellowish margin on which is a very short 

 but rather dense fringe ; thoracal pair consisting of only a narrow pale greyish 

 yellow bare frenum. Halteres with large elongate dark-brown knobs and 

 with brownish yellow stems. 



. Considerably distinct from the male. Frons at the occiput more than one- 

 quarter the width of the head and gradually widening downwarcls, with 

 no middle channel but with a rather short rather dense black pubescence 

 except on the middle ; back of the head light greyish brown, puffed out from 

 the eyes, and bearing very numerous very short bristles on the upper part
