CEYLONESE APHIDES. 
183 
after the final moult, but soon darkens to brownish green; with 
the thorax and bands across the abdomen brown ; the eyes are 
bright crimson. The antennae, legs, and honey tubes are brownish, 
and the space below the eyes is brown. 
Winged Viviparous Female. 
Head furnished with three large ocelli; two at internal anterior 
margin of eyes, the third middle on the front. Eyes like apterous 
female. Front with a median impression, and very slightly pro¬ 
minent at base of antennae. Antennae with the first joint slightly 
larger than the second ; third the longest, more than twice the 
length of fourth, fifth slightly longer than fourth, (sixth) shorter 
than fourth, (seventh) shorter than third (sometimes nearly 
equal) ; relative lengths : third joint = 12-13*3 ; fourth joint 
= 4*8-5*6 ; fifth joint = 5*5-6 ; sixth joint = 4*2-4*3 ; seventh 
joint = 7*5-7T2 ; third joint with numerous foveae (fig. 3) ; third 
to seventh imbricated ; all the joints with some bristles ; fifth with 
a subapical fovea ; (sixth) with foveae at base of (seventh). Head 
and pronotum with somewhat rare bristles ; mesonotum with the 
bristles more numerous on posterior part; dark brown. Abdomen 
fasciated with brown, not setose. Cornicles dark brown, nearly 
cylindrical, longer than half the body ; tail short; caudal segment 
convex. 
Anterior wings longer than the body, elongated, with dark veins 
clouded at tip ; stigma elongated, first oblique vein straight, second 
peculiarly -—' curved ; cubitus not reaching the cubital vein (sensu 
Lichtenstein) usually twice forked, but sometimes the outer branch 
is not forked. 
Inferior wings longer than the body ; costa subparallel to the 
margin ; two oblique veins, not parallel, remote at base. 
Long.: 1*70-1*85 mm.; wing 2*20-2*35 mm. 
Greenidea artocarpi feeds in Ceylon on Artocarpus integrifolia 
and Onesma ferrea. 
Mr. Green observed that “ when alarmed the insects suddenly 
dropped from the leaves to the ground. They are very active and 
walk rapidly.” 
N.B .—The drawings which accompany the description given by 
Westwood are not at all exact; compare, for example, the antenna 
he represents (fig. 9 of his plate) with the one I here figure ! So 
he draws three short joints at base in place of two only. Owing 
to a remark of Mr. Green, Westwood in his second notice figures 
rightly the eye of the species (the drawing here reproduced was 
of too small size to give the exact proportion of the appendix).
