antenn?e 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 oeiitre, and on the sixth segment the three black spots almost 

 cover it, so that the spécimen ùs almost identical with the var. 

 strigata of Staeger. 



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

 from North Africa (Ethiopia) apparently it has nevcr previously 

 becn found in Egypt. The small série» whieh I posscss, hâve been 

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

 Pyramids) and one fcniale froni the Wadi-IIoff. My dates extend 

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

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

 Europe.
