tured ; the scape of the antennae black, the flagellum reddish yellow 

 and more or less fuscous above ; a minute spot at the anterior 

 margin of the clypeus and an oblong angulated one on each side 

 of the face reddish yrllow. Thorax : the collar, tubercles, tegulae 

 in front, and the basal half of the tibiae yellow ; the apical joints 

 of the tarsi fusco-ferruginous ; the metathorax covered with short 

 white pubescence, except the enclosed portion below the scutellum, 

 which is deeply rugose. Abdomen short, rounded, smooth and 

 shining. The spots on the face sometimes quite or nearly obso- 

 lete. B.M. 



Male. Black ; the face below the insertion of the antennae and their 

 scape in front pale yellow ; the tiagellum fulvous beneath. Thorax, 

 the collar, tubercles, and tegulae in front, tibiae and tarsi bright 

 yellow : a spot on all the tibioj behind and the apical joints of the 

 tarsi ferruginous ; wings hyaline, splendidly iridescent. Abdomen 

 closely and finely punctured. B.M. 



This is a rare species ; I never met w ith it at large, but have bred 

 it from bramble- and rose-sticks sent from Bristol. In the British 

 Museum are specimens from Devonshire.
