black, except at the base where they are brown, and the subcosta 

 yellowish; Radius 4 + 5 is much more dipped than in the other 

 species of this genus, nearly as much as in Eristalis; the stigma 

 is short, small and only slightly darkened. Squamulae with their 

 fringes white, and their margins yellow. Halteres white. 



Length, about 13 mm. 



This species is provisionally included in the Lisl of Egyptian 

 Syrphidse, but hitherto it has only been recorder from Romani 

 where a single female was captured by A.W.Boyd on 23.9.1910, 

 the specimen being in the collection of the Entomological Section, 

 Ministry of Agriculture. This specimen lacks both antennae, con- 

 sequently the above description of them has been burrowed from 

 Prof. Bezzi's type. The only other female known, from Tatahonina 

 (North ? Africa), belongs to the Budapest Museum, from which 

 Prof. Bezzi made his original description. Our specimen from Ro- 

 mani, however, seems to be different from the type as regards the 

 colour of the abdomen ; in the original description : 'Abdomen 

 "elongatum, jilanum sed conicum, basi thorace non latius, apieem 

 "versus valde attenuatum, totum nigroaeneum nitidum, passim 

 "paullo purpurascens; segmentum primum immaculatum, secundum 

 "lateribus paullo et obscure rufescentibus, lunulis duabus albis, ob- 

 "liquis, separatis intus rotundato-dilatatis et semper sat distan- 

 "tibus; quintum breve, immaculatum..." 



Further knowledge of this curious and interesting fly is much 

 to be desired, as it represents a distinct group of this genus ow- 

 ing to its comparatively slender hind femora, and its wing vena- 

 tion; moreover nothing is known about its habits. The male is un- 

 known.
