of tlie tibiae always to a small extent (so small as to be easily overlooked) 

 reddisli brown. Pubescence (as distinguished from bristles unless included 

 under bristles) on the front coxae abundant coarse drooping long and whitish, 

 on the middle coxae similar but limited to the apical half, and on the hind 

 coxae only moderate, whUe a short depressed pale pubescence occurs all over 

 the legs though less depressed longer and yellower on the front femora, and 

 some long pubescence occurs on the back and underpart of the front femora, 

 moderately beneath the middle femora and sparsely beneath all the tibiae. 

 Bristles on the front femora limited to a row of (about six) long black 

 bristly hairs beneath, and a few subapical ones of which four or five are 

 small orange antero-dorsal and three insignificant black postero- dorsal ; on 

 the front tibiae one or two small orange or black slightly antero-dorsal near 

 the base, about five black postero-dorsal on the apical three-fifths Avith 

 frequently a slight row of (3-4) of rather shorter black bristles just posterior 

 to them, about six ( = more than usual) long orange postero-ventral in an 

 irregular row on the apical three-fifths, and the usual apical circlet of orange 

 bristles (unless two small dorsal ones be black) ; on the front tarsi the bristles 

 all strong and yellow except a few black plantar and one or two others on the 

 third and fourth joints ; on the middle femora three or four long antero-dorsal 

 (almost anterior), about five rather smaller antero-ventral on the basal three- 

 fifths, a few small praeapical of which one postero-dorsal is conspicuous, and 

 eight to ten rather long postero-ventral (almost ventral) thin hairs of which 

 the last two or three may merge into the praeapical postero-dorsal bristles 

 and be black ; on the middle tibiae are numerous mainly yellowish bristles in 

 rows, there being about five usually pale dorsal (none near the base), three 

 antero-dorsal (the uppermost a long one at the middle), about three antero- 

 ventral after the middle, five postero-dorsal (nearly posterior), and about ten 

 long thin postero-ventral hairs of which two are extra long and sometimes 

 blackish or all may be blackish ; on the middle tarsi are long and con- 

 spicuous bristles, mostly yellowish white but one or two black ones occur in 

 the apical circlets of the thii'd and fourth (or even first and second) joints 

 and one posterior one on the third joint ; on the hind femora are five to seven 

 V yellowish black anterior bristles of which the last two become rather 

 antero-dorsal, five (or more) yellowish antero-ventral, six or seven almost 

 hair-like postero-ventral, and a praeapical circlet of about six yellowish 

 bristles ; on the hind tibiae are two dorsal after the middle and one almost in 

 the same row near the base (or even one or two more in the same row) 

 which are sometimes all black, four or five antero-dorsal, one long postero- 

 dorsal near the middle with sometimes others (not quite in the same row) 

 before and after it, about four antero-ventral not extending to the base, a 

 ciliation of partly blackish thin ventral hairs, and the all yellowish apical 

 circlet ; on the hind tarsi the bristles are mostly yellowish, but usually each 

 of the four basal joints has one apical antero-ventral black, and the third 

 and fourth (or even second) joints one postero-ventral black. Pulvilli elongate 

 oblong, brownish orange ; claAvs long and dull black, but dull reddish orange 

 about the base. 



Wings hyaline, but rather brownish orange about the base and in old 

 specimens with a distinct brownish yellow sutiusion and then with the veins 

 (except about the base) darkened, but without any ti-ace of the peculiar greyish 

 " gloom " which occurs in so many species about the tip and hindmargin ; 

 cubital fork-cell proportionately rather short and broad with a wide bell- 

 mouthed opening. Squamae (alar) brownish white on the muscular basal part 

 but whitish or yellow on the disc and on the thick margin ; fringes whitish, 

 rather long and abundant, but ceasing at the angle. Halteres brownish 

 orange. 



5 . Very much like the male except for the conspicuous ovipositor. 



Face-beard sometimes with more black hairs on especially the upper part. 



Thorax with the anterior praesutural bristles more frequently black. 



Abdomen still more conical. Ovipositor (fig. 357) black, strongly compressed, 

 and of a very characteristic broad triangular sabre-shaped figure which is pro- 

 duced so that the upper margin is rather concave but the under margin 

 strongly convex ; the basal upper piece bearing dense minute bristles about
