The pupa havea green intercornicular band and rows of white spots on the back. 
Alate viviparous female. —It is slightly smaller than the apterous female ; the cor- 
nicles also are comparatively smaller. The pattern on the abdomen is indistinctly 
marked; on the mid-dorsum of the abdomen three faint spots can be observed on the 
first three segments, also two bigger stripes on the two posterior segments. 
The structure of the antennae is characteristic, although its length varies accord- 
ing to the size of the individual; smaller specimens may be even less than three- 
fourths of the larger ones. 
The antennal articles are long and well marked; all are imbricate.
