 1. 15 ? . 



Female. Length 5-5^ lines. — Black ; a spot between the an- 

 tennae, and a minute one behind each eye, yellow ; the scape 

 of the antennae at its apex beneath, and the apical joint of the 

 flagellum beneath, fulvous. Thorax : the border of the pro- 

 thorax yellow ; the knees, tibiae and tarsi ferruginous, the an- 

 terior, and sometimes the intermediate pair also, with a black 

 stain behind ; the wings fulvo-hyaline, with a fuscous stain 

 along the anterior border of the superior pair. Abdomen : the 

 first, second and third segments bordered with yellow, that on 

 the first a little widened at the sides of the segment, the second 

 continued beneath. 



The Male is rather smaller than the female, and differs from it in 

 having the mandibles, clypeus, and scape in front, yellow, and 

 four or five of the apical joints of the flagellum ferruginous ; 

 the legs are yellow, with ferruginous stains; the second and 

 third fasciae of the abdomen both continued beneath. 



This pretty species is not found near London. I have taken 

 it at Walmer and Kingsdown, Kent, during July and August ; 

 also at Pakefield and Lowestoft, Suffolk ; it occurs in Scot- 

 land, and has been taken at Loch Rannoch, in Perthshire.
