The cottony flocculence resembles very much a similar secretion met with in Pem- 
phiginae and Chermesinae, but the structure of these glands is quite different.' 
Alate male.—Body rather slender ; its small size and black colour differentiate 
it from the alate viviparous female. There are alate viviparous females which are 
of the same dimensions and even smaller, but their bodies are either greenish or pink- 
ish, never dark rusty which is the prevailing tinge in the male. Moreover, the anten- 
nae and legs are black throughout, the former unlike the ringed antennae found in 
viviparous females. . 
Head black, with conspicuous eyes; much broader than long; front bifid ; not 
very flocculent in life. 
Antennae comparatively long; 3rd joint longest; all the rest subequal.

Sensoriae somewhat elliptical, not quite circular; present on all the joints. On 
article III about twenty (20); on IV, 8—10; on V,8—10; on VI, 6—8. These are in 
addition to the primary sensoria on articles V and VI. Almost all the sensoria have 
a hair-rim ; on the primary ones it is more distinct, consisting of larger hairs. 
Prothorax with rounded lateral edges, narrower than the head, concolorous ; two 
glands of a whitish colour are conspicuous near the posterior edge. 
Mesothorax and metathorax, including wings and legs, like the alate viviparous 
female, but darker. 
Wings not voluminous as mentioned by Western authorities for males in other 
Aphids. In the males of other Punjab Aphids also I did not find the wings voluminous. 
Abdomen narrow, well segmented, blackish rusty, with the usual four rows of 
glands. 
Cauda distinctly smoky ; below it is the conspicuous genital armature. It con- 
sists of two lateral claspers, triangular in form and with the apices directed forwards ; 
their ventral surface has a black boundary and is beset with whitish spiny tubercles. 
Between them, in the angle formed by their inner edges and nearer their bases, is the 
conical light-coloured, small penis, also bearing tubercles ending in curved spines. 
On either side of the penis running backwards and outwards is a lateral black ridge. 
There is a ridge in front of the two claspers and two more, one on either side, 
1 [Mr. Das’ description of the wax-glands of Shivaphis celti not being quite accurate I feel obliged 
to add the following notes :— 
The wax-glands open on rounded or ovate, somewhat chitinized wax-plates. A plate bears numerous 
groups of facets, the groups being always distiuctly separated from one another; each group consists of 
a small number of facets (mostly 4 to 10), of a polygonal form, with a broad chitinous rim, and completely 
fused together. ‘I'he membrane of all facets shows some fine pores, through which the waxy substance 
is secreted. 
Each plate bears a single long plate-hair ; the outlines of the plate are in most cases not distinct.
