 of the metanotum immediately before each other golden 

 yellow. The elytra black, with the shoulders narrowly 

 and the suture broadly golden yellow; the wings iridescent, 

 hyaline , with the costal portion brown. The legs black ; 

 at the anterior pair the apex of the coxae , the trochanters 

 and about the basal half of the femorae , at the interme- 

 diate pair the apex of the coxae and the trochanters and 

 at the posterior pair the coxae and the base of the tro- 

 chanters and femorae pale yellow. The abdomen black, 

 the lateral margins of the segments yellow , broader at the 

 posterior edges, but less distinct towards the apex; the 

 posterior margin of the segments most narrowly margined 

 with yellow , that of the two penultimate segments broader.
