antennae blacker on the dorsal surface and at the apex, and with 

 the three yellow bands of the second, third and fourth segments 

 of the abdomen very narrow and rather widely interrupted in 

 the centre, and on the sixth segment the three black spots almost 

 cover it, so that the specimen - is almost identical with the var. 

 strigata of Stseger. 



S. scripta is a rare species and although it has been recorded 

 from North Africa (Ethiopia) apparently it has never previously 

 been found in Egypt, The small series which I possess, have been 

 captured at Marg (near Cairo), Kerdace (North East of the Ghizeh 

 Pyramids) and one female from the Wadi-Hoff. My dates extend 

 from February to June. It is known to occur in Asia Minor, 

 Canary Islands, Japan, North and South America, and throughout 

 Europe.
