ending at about two-thirds of the way down are continued to the 

 lower margin, thus rendering the latter a uniform dull grey. The 

 fifth segment of the abdomen is small and triangular. Wings more 

 pellucid than in the male. 



Length from 9 to 12 nun. 



This species is extremely common in Upper as well as Lower 

 Egypt, and it may be found on flowers practically all the year 

 round. My dates are from October to the same month of the follow- 

 ing year, in Cairo. 



It is recorded from nearly all Europe, and North America, 

 Algiers, Syria, even far down in Africa and probably occurs in 

 many other parts of the world.
