Black with the abdomen golden-yellow except the base 

 of the two first segments. On each side of the 2d and 3d 

 segment in the hind angle there is a little elliptical dark 

 reddish spöt projecting upwards as a short curved stripe of 

 the same colour. On the fourth segment only the stripes 

 reinain, and in addition to these comes a large transversal 

 spöt of the same colour in the middle of the dorsal part. 

 The body is clothed with cinereous-yellow hairs, the abdomi- 

 nal segments ciliated with golden-yellow ones. The head is 

 nearly impunctated except round the base of the antennee. 

 The pronotum is densely punctured, but the other parts of 

 the thorax nearly impunctated. The side-furrows on the 

 mesonotum are very deep and distinct. The median segment 

 projects a little upwards in the middleline. The abdomen is 

 nearly impunctated. The wings hyaline with the base and 

 the costal margin dark fuscous-brown and with a verv dull 

 violet effulgence. The radial cell not twice as long as high. 

 The interval between the anterior inserting-points of the both 

 recurrent nervures on the cubital nervure a little longer than 

 the distance between that of the second recurrent nervure 

 and the posterior one of the second transverse cubital ner- 

 vure. 



Length 13.5 mm. Exp. 26 mm.
