MORPHOLOGICAL DESCRIPTION. 
_ Apterous viviparous female.—A small-sized species, hardly visible when only a 
few are sitting in the indented margin of a leaf; rounded or broad oval in form; 
widest just in front of the cornicles and gradually narrowing towards the head. 
Colour shining green,-without mealy powder, very much resembling the leaves of 
the host. 
Eyes brilliant red, without distinct stemmata. 
Head yellowish-green, as long as broad; front large and convex, with bases of 
antennae quite wide apart, without any trace of frontal tubercles; some capitate 
hairs project anteriorly. 
The absence of ocular tubercles is rather rare in Aphidinae.' 
Antennae short, about half the body length, proximal half of the colour of the 
head, the rest black ; the joints are distinctly marked. 
Spur of article VI slightly shorter than that of III; IV, V and base of VI sub- 
equal. The length of the basal part of VI is noticeable.
