Botli for this and the following species the full synonymy will 

 no doubt be mainly the same as given for arcuata, all tliree species 

 probably being included in the descriptions. 



Male. Frons black, less greyish pruinose than in arcuata, slightly 

 shining; outer bristles of second row not present (in any of my numer- 

 oiis specimens). Antennæ brownish black. Palpi yellowish to blackish. 

 Thorax black or a little brownish black, somewhat shining, the 

 longitudinal fiirrows and the flat area behind not pruinose, but the 

 furrows not rarely reddish or brownish translucent. Scutellum with 

 four bristles (according to Schmitz very rarely with six). Abdomen 

 greyish black, dull. Hypopygium generally withdrawn, wlien exposed 

 not large, yellow, shining; anal tube yellow, small and very slightly 

 projecting. Legs yellow, femora sometimes darker. Wings brownish 

 or sometimes more blackish tinged, veins blackish brown or thin 

 veins black; costa not reaching to the middle, increasing in thickness 

 from the base outwards; it is curved a little inwards so that the wing- 

 margin is here a little concave; division 2 and .3 of about equal length; 

 fourth vein nearly straight, but curved strongly upwards in the apical 

 part, ending a little anterior to the apex of the fifth vein. Halteres 

 yellow. 



Female. Similar; abdomen without tergal plate only on fourth 

 segment, the third tergite is short, broadly rounded behind, the fifth
