 broad, longish line, narrowed at base and apex in the centre of scutellum, 

 a mark at the sides of postscutellum, the greater part of the metanotum, 

 four transverse bands (the second much larger than the others) on the 

 back of the abdomen, the apical segments almost entirely, a large some-
