Mr. Kiyatake collected some wingless viviparous females and 
a nymph of the winged form on an unknown plant in March, 
1921. The specimens from Johore differ slightly from the 
original description as follows: 
Wingless viviparous female——Yellowish green; antenne pale 
yellowish green, with the apex of the fourth joint and the fifth 
dusky; legs and abdominal tubercles pale yellowish green; eyes 
dark reddish (color notes from specimens preserved in alcohol) ; 
body oval, lacking hairs; head provided with a few very small 
hairs; front wide; frontal tubercles almost absent; eyes very 
small, composed of three facets; antenne short, 5-jointed, im- 
bricated, with three or four very small hairs; the third joint 
lacking sensoria; the fourth with a circular apical sensorium 
of medium size; the relative length of joints as follows: III, 
50-52; IV, 25-30; V, 37 (22+15)—41 (23+18). Rostrum 
somewhat stout, reaching the middle coxxz; body lacking lateral 
tubercles; spiracles not protuberant. Abdomen just above the 
cauda provided with a pair of long and slender, hornlike tuber- 
cles, projecting horizontally far beyond the caudal apex, which 
is a little shorter than the fifth antennal joint, striate, slightly 
curved, sharply pointed and almost twice as long as the hind 
tarsi, provided with a short bristle at the apex; cornicles very 
short, cone-shaped, of lachnid appearance, slightly striate, pro- 
vided with one or two very small bristles; cauda not distinct, 
with some rather long, very stout bristles; legs provided with 
a few short bristles, tarsi rather short, roughly imbricated, with 
very long bristles at the apex. Length of body, 1.9 millimeters ; 
antenne, 0.9. 
This species is hitherto unrecorded from the Malay Peninsula.
