This conspicuous species varies in the markings on the scutellum 

 and postscutellum : sometimes the former has a broad white margin, 

 the latter having only a short white line. Probably a series of spe- 

 cimens would show many variations in these markings.

 tellum, metathorax, pectus, and legs black. Antennas red ; the 

 tubercles, and a patch behind but united with them in colour, a 

 large macula on the scutellum, and the postscutellum yellow ; the 

 tibiae and tarsi more or less obscurely red ; wings hyaline and iri- 

 descent, the nervures ferruginous ; the mesothorax closely punc- 

 tured. Abdomen finely punctured ; beneath more or less black 

 towards the base.
