Alate viviparous female.—Body smaller ; colour similar to the apterous female ; 
dirty light green, deep anteriorly and light behind, with about six irregular dark 
spots; also a rusty area in the mid-dorsum. 
There is no pattern on the abdomen except the reddish-brown patches around 
the cornicular bases, and three darkish spots on the carinae in front of the cornicles. 
Head broad, pitch black, with similar antennae and eyes. 
Antennae large, black, except for a very small basal part of the third article 
which is lighter, narrower and devoid of sensoria. The rest of this joint and the 
fourth are strongly tubercled and studded all round with sensoria. ‘The spur and the 
third joint about equal in length or the 3rd a little longer. ; 
Sensoria very many on the third, upwards of thirty-five (35); the fourth has 
about a dozen (12); often one or two on the fifth and sixth in addition to the two 
primary sensoria which have a distinèt hair-rim. 
All the secondary sensoria on III and IV have a double contour.
