The “ anal end ’’ is characteristic on account of a large rectangular almost verti- 
cal anal-plate, outlined with dark stiff hairs ; its centre is occupied with a prominent 
wax-gland !, the secretion from which flows like a tail behind the insect. The anus is 
raised upwards and is placed almost on the dorsal surface, forming a semicircular 
opening. Ventrally there is a black crescentic genital plate with its concave end 
facing backwards. 
The rudimentary gonapophyses are conspicuous as two rounded dots, beset with 
a few hairs to each. 
Legs very small; tarsi long, about half the size of tibiae. 
Rostrum short and stout; it reaches up to about the third coxae, because all the 
legs are situated close together. Its three segments are subequal; the last one black- 
tipped and triangular.

The pupae, which develop about October, are very similar in appearance to 
apterous viviparous females. They are quite yellow and tassellated with glands as 
usual; they only change colour when approaching their final moult in November. 
Slowly the dirty greenish tinge invades the thorax and abdomen. The shoulders 
are whitish. 
Alate viviparous female.—Body elongate oval; dull black or very dark green. 
Head, antennae, prothorax, legs and rostrum black ; mesothoracic bosses large and 
shining black. The white powder forms only a thin layer over the surface. 
Head broad, without frontal tubercles, with two or three depressions on vertex ; 
front bilobed with a median groove. Eyes and ocelli well developed, black. Anten- 
nae short but relatively a little longer than those of the apterous female. Unlike the 
latter the number of articles here is six. All the joints are narrow at the base and 
gradually widen towards their distal ends. The spur is about half the base of VI.’
