Antennas not much longer than abdomen, scape black, the rest of 

 the joints black, those near the scape brownish on underside ; the third 

 joint a little shorter than the second, and not much longer than the 

 fourth and fifth together. Head black, a line on clypeus, mandibles 

 at base, a broad fascia proceeding from the inner side of the eyes to 

 back of head, where it becomes broader, and a narrow stripe along the 

 sutures on vertex, yellow. Behind the ocelli the head is smooth, 

 shining, with only a few shallow scattered punctures ; below them it is 

 more strongly and more numerously punctured, and is not so shining. 

 Thorax black, shining; tegulae, the base of pronotum, scutellum, and 

 post-scutellum, yellow. Abdomen black above, the third and fourth, 

 and part of fifth, and apical segments, fulvous, the sides and ventral 

 surface yellow. Legs straw-yellow, coxae black at base, tarsi reddish- 

 yellow. Wings hyaline, stigma fuscous, paler in the middle. 



Length 5 lines. 



The short third joint of the antennae separates easily

The larva is unknown, but Saxesen (Zaddach, 1. c.) 

 suspect that it feeds on rose. My specimens were
