'iiiiu! ;ii;ii'yiii ishroader; thèse distinctions are however variable.as I 

 '"hâve seen females quite as orange as an ordinary maie, while on 

 "thc other hand I hâve seen a female from Bigot's collection labelled 

 "Corsica" in which the middle bancls were devided into side spots. 



"Puhescence shorter, and more black on the abdomen. Frons 

 "narrow but gradually widening down to the base of the antennae, 

 "aud it is greyish-yellow with an idefinite dark middle line, but 

 "shining orange above ths antennaN while the ocellar triangle is 

 "almost shining black. Anlcniuu oiten aliiiost ail brown. 



"Length aboul 10 mm. 



''The métamorphoses of this species bave been often observed 

 "and Zetterstedt states that ths larva feeds on the Aphids of the 

 "common iiean (Faba) and Potatoe (Solanum esculentum); Mr. G. 

 "C. Bignell bas bred it from Avhis pruni; Mik has dealt with it 

 "at some length in Wien. Entom. Zeitg. XVII. p. 169. (1898)." 



As I possess only a single si^ecirnen of this species the above 

 account has been copied from Verrall's excellent description. This 

 individual, a maie, measuring over 12 nun. in length was caught 

 by Mr. Kirkpatrick at Giza. December 2nd, 1921, where it was 

 found hovering in a field of clover. 



This spécimen agrées with Verrall's description, except for the 

 second segment of the abdomen in whicli the orange is much less 

 extensive ; in fact the whole of the second .segment is rather shining 

 black, except for two isolated and elongale orange spots on the 

 sides, (Plate IV, f.g. 6). 



As far as I am aware this is thc fir.st record of thc occurence 

 of S. haltmtus in Egypt but it is kiiown to ocenr in other parts 

 of Nortli Africa, (e.g. Morocco). 



It has also bccn reeorded from Asia, Tiidia. .\us'.ralia, Spain, 

 Cliina, Japan, Tcrnatc and is commun throughoiit Europe.
