Pupa long oval; on the brown head the red eyes and smaller ocelli are visible. 
Prothorax and central mesothorax green. Wing-pads whitish. The abdomen shows 
a similar pattern on the back as in the apterous viviparous female. | 
Alate viviparous female.—Body a little smaller than the apterous viviparous 
female, but very variable, with long hairs all over the body situated on tubercles. 
Head dark brown, slightly grooved in front; median ocellus placed ventrally. 
Eyes red. 
Antennae dark, short, reaching half way down the back, somewhat curved near 
the apex. 
The length proportions of the articles vary considerably, but usually III is sub- 
equal to IV and V taken together and smaller than VI including the spur, which is less 
than three times the base (about two and a half times). ‘The spur in most speci- 
mens is a little shorter than III but sometimes subequal.

(='30 mm). 
The secondary sensoria are large and few in number, placed only on the distal 
half of article III. The number varies from two to five (2-5), usually there are four. 
There are no hair-rims and the double contour is circular. . 
The primary sensoria possess a circlet of hair and are of normal type. 
Prothorax and mesothorax normal, black ; after immersion in alcohol two spots 
are seen on the former. 6 
Wings hyaline; venation normal but variable, as shown in the figures. Costa 
thicker than other veins, but not asthick as the subcosta. Stigma brown; its 
posterior border beats a row of characteristic hooked spines, and behind these runs 
another streak like a false vein. The cubitus sometimes has three forks. The pos- 
terior wing rarely has two oblique veins, usually only one. 
Abdomen pyriform, greenish-yellow, with a similar pattern of dark green bands 
as in the apterous viviparous female, that is two large latero-dorsal spots on first 
abdominal, two crescentic ones around cornicles not meeting with each other any- 
where, and two small spots on the precaudal segment. There are no lateral tuber- 
cles but two rows of black dots are well seen on the lateral grooves and margins. 
The cornicles appear as rings from above, with a clear light greenish space around 
their bases. They are similar in form to those of the apterous viviparous female but
