The species of this genus highly resemble those of the preceding, 

 but they are of smaller size; they are likewise metallic coloured. 

 The head is semiglobular, excavated behind. a little broader than higli 

 and broader than the thorax. The face is not protruding but in a 

 level with the eyes. The antennæ are in.serted a little below the 

 middle of the head. Face and epistoma retreating: yowls very narrow, 

 not descending below the eyes but on the contrary bent upwards. 

 Antennæ short, seven-jointed in all, the two basal joints of equal 

 length, the four foUowing forming an annulated, compressed part, the 

 last forming an arista, inserted in the dorsal side of the foregoing 

 joint. Eyes bare or indistinctiy hairy, touching in the male, widely 

 separated in the feniale; in the male the upper facets larger than 

 the lower. The oral cone and the proboscis are short, the labella 

 rather broad, disciform when spread out; for the rest the mouth parts 

 as in Chloromyia. Thorax is somewhat longer than broad; scutellum 

 unarmed. Abdonien is slightly broader than the thorax, consisting of 

 tive segments. The male and female genitalia similar to those in 

 Sargus. The wings have a distinct radial vein and a forked cubilal 

 vein; four veins rise from the discai and second basal cell of which 

 the first and third are generally weak, the fourth is the anterior
