Face with a sharp central keel ; the vertex of the male is long and 

 narrow; frons bare, short and slightly produced. Eyes large, quite 

 bare, touching for a fairly short distance in the male, but widely se- 

 parated in the female. Antennae moderate with a rather long and 

 rounded third joint, which bears dorsally a long and bare arista, 

 Thorax rather long and with the base, humeri, the sides down to the 

 suture, as well as all the pleurae, covered with pale, light coloured 

 dust. The abdomen is thin, elongated and brightly coloured with 

 yellow and black ; the anterior margin of the second segment runs 

 forward at each side, for a distance equal to nearly half 

 the length of the first segment. Legs with the two anterior pairs 

 quite normal but with the hind femora extremely dilated and 

 possessing short rigid spines beneath. Wings with the radio- 

 median cross-vein upright and placed at the middle or cell M2. 



This genus shows some relationship with Eumerus. Although 

 it is a very small genus, it is very widely distributed and seems to 

 be exceedingly abundant wherever it is represented. It occurs 

 commonly in the Ethiopian Region, Nubia, Aden, Sierra Leone, 

 Senegal, Madagascar etc., Asia, North America, New Zealand, 

 throughout Europe and in Eastern India.
