"bind margin lsbroader; these distinctions are however variable.as I 

 "have seen females quite as orange as an ordinary male, while on 

 "the other hand I have seen a female from Bigot's collection labelled 

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



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

 "narrow but gradually widening down to the base of the antenna?, 

 "and it is greyish-yellow 7 with an idefinite dark middle line, but 

 "shining orange above the antenna?, while the ocellar triangle is 

 "almost shining black. Antenna? often almost all brown. 



"Length about 10 mm. 



"The metamorphoses of this species have been often observed 

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

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

 "('. Bignell has bred it from Avhis pruni; Mik has dealt with it 

 "at some length in Wien. Entom. Zeitg. XVII. p. 109. (1898)." 



As I possess only a single specimen of this species the above 

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

 individual, a male, measuring over 12 mm. in length was caught 

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

 found hovering in a field of clover. 



This specimen agrees with Verrall's description, except for the 

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

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

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

 sides, (Plate IV, tig. 6). 



As far as I am aware this is the first record of the occurence 

 of S. balteatus in Egypt hut it is known to occur in other parts 

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



It lias also been recorded from Asia, India, Australia, Spain, 

 China, Japan, Ternate and is common throughout Europe.
