1918.] _ BASHAMBAR Das: The Aphididae of Lahore. 247 
Eyes brilliant red, with well-developed ocular tubercles. 
Antennae wide apart at their bases, reaching half way down the back; junctions 
of articles black, alternating with the rest of the segment that is whitish or yellowish ; 
appearance ringed. Last segment (VI) with a very short spur or ‘‘ processus termi- 
nalis,’’ similar to that found in Lachninae or Phyllaphis ; 3rd article longest, about 
twice the size of IV, V or VI, which are all subequal ! :— 
| III. IV. VE VI. 
Lengths 0°34 0277 0'17 0o'I6 mm. 
Prothorax well defined, elliptic, broader than long; lateral edges rounded, bear- 
ing large black glands; four more glands in two pairs, one behind the other, on the 
upper surface, and two latero-dorsal black depressions. 
Meso- and metathorax like the abdominal segments furnished with two median 
and two lateral dusky round glands. 
The abdomen bears four rows of black spots which are the wax-secreting glands, 
one on either side on the carinae and bulging outwards and two on the middorsum. 
Over the greenish or pinkish dorsal surface three or four faint whitish longitudinal 
lines or grooves are noticeable; transverse segmentation of the abdomen cut these 
grooves across, marking the surface into squarish areas in the middle of which lies a 
gland. À row of blackish depressions runs upon the lateral grooves, continuous 
along the whole body. The two median spots of the penultimate segment are larger, 
while those of the last one are confluent with each other. This segment has no lateral 
glands. 
Cornicles little more than black rings with whitish centres, hardly rising above 
the level of the wax-glands; outline double, like a sensorium. 
Cauda of the colour of the body, with the tip only dusky ; almost cylindrical, 
resting on a broad watchglass-like swollen base ; there are strong spines as usual. 
Anal plate blackish, deeply bilobed or cleft like the letter U ; the two limbs of 
the U enclose the cauda and project as far, so that three processes seem to be present 
at the anal end. 
Genital plate much in front, large and prominent, about the same colour as the 
anal plate. With a high power three rudimentary gonapophyses can be discerned 
just behind the genital plate.’ 
Legs pale brown, almost of the body colour, except the stout black coxae, spe- 
cially the hindmost ones. Distal femora and tarsi also black. In life covered with 
thick flocculence.’ 
! [The spur of the sixth joint is not so very short, its length being about 1 the basal part of the 
ultimate joint. 
On the under side of the antennal joints 3, 4 and 5, there are present at the tip a number of small 
wax-glands, of the same form as those on the dorsum. P. v. d. G.]. 
? [The number of rudimentary gonapophysae is apparently 2; they are placed very close together 
and often seem to be united. P. v. d. G.]. 
8 [On the basal part of the tibia and the distal half of the femur small wax-glands are visible of 
exactly the same form as those on the dorsum of the body. P. v. d. G.].
