broad black spots on the lower half ; subocular dark spot less distinct ; antennae 

 entirely yellow, the second joint with some short and one long bristly black hairs, 

 the third joint rather short and a little attenuated towards the end ; palpi yellow, 

 much dilated at the end, the dilated part almost rounded ; all the bristles black, 

 three pairs of lower fronto-orbitals present, the two apical pairs being less approxi- 

 mated than usual. Thorax entirely black, punctulate, rather shining, chiefly on 

 the pleura and breast ; on the dorsum there is a greyish pubescence, which is longer 

 than usual, and on the sides, humeri and pleura there are rather long and soft hairs 

 of a pale yellowish colour ; on the dorsum, seen from behind, there are two broad 

 and distinct parallel stripes of grey dust, abbreviated behind, but not interrupted at 

 the suture. All the bristles are black ; middle scapular indistinct ; anterior supra- 

 alar and praescutellar well developed ; pteropleural very thin. The yellow markings 

 are rather small and as follows :■ — the humeral calh, but while in all the preceding 

 species they are entirely yellow, in the present species they have a black border on 

 the inner side ; a very narrow streak on each side behind the suture ; a narrow 

 mesopleural stripe, not extended above because the sutural callus is quite black, and 

 not prolonged on the sternopleura, which has only the upper border dark reddish 

 brown ; this mesopleural stripe is besides not dilated above on the notopleural 

 suture, being almost of equal width throughout ; two contiguous hypopleural spots. 

 Mesophragma entirely black. Scutellum black, punctulate and pubescent like the 

 dorsum, with a pair of strong, apical black bristles ; the two yellow spots are very 

 narrow, rounded, and placed on the extreme lateral angles, but decidedly dorsal ; 

 the inferior side of the scutellum is yellowish. Squamae pellucid, with a white fringe, 

 halteres whitish yellow. Abdomen entirely black, punctulate and pubescent like the 

 thorax, and with rather long pale hairs towards the base ; first segment with a very 

 narrow, linear, hardly distinct yellow hind border ; second segment with a little 

 broader yellow hind border, which is interrupted in the middle and does not reach 

 the sides ; fifth segment with a narrow yellow hind border, which is dilated above in 

 the middle ; venter and genitalia black ; third segment with long black ciUa at the 

 sides. Legs with black coxae and trochanters ; front femora almost entirely, the 

 four posterior ones on the apical third, shining black ; the four anterior tibiae yellow, 

 hind tibiae black ; all the praetarsi yellow, the four other joints more or less blackish ; 

 femora with rather long white hairs ; middle tibiae with a black apical spur. Wings 

 slightly yellowish hyaline, with blackish veins ; no costal border, but the stigma 

 black and the very narrow subcostal cell dark yellowish ; a rather broad, isolated 

 brown spot at the end of the third vein ; a less distinct dark spot at the lower end of 

 the hind cross-veins and at the apex of the fifth vein ; anal cell altogether hyahne, 

 no anal stripe and even the dark spot at the end of the anal vein rather small. 

 Supernumerary anal lobe distinct, but less developed ; last section of fourth vein 

 curved at the base, but straight at the end.
