Distribution. Coimbatore. Probably throughoul Southern India. 

 Lifehistory. The insects, in various stages from young to winged 

 adults, occur on the undersurface of leaves ol thi Gianl B 

 (Dendrocalamus), sometimes in verj large numbers so that the plant 

 is smothered with a black fungus which grows on the honey-dew 

 1 by tin- insect-, this sweet excretion being also visited In 

 hordes of flies, ants and other insects. Tin- young insect is pair 

 greenish-yellow with a pair oi very long projei ting cephalic 



.lined in size in the adult ins< 

 it grows, the bod) becomes spherical, flattened, hut the head and 

 thorax remain distinct ; in colour it is pale \ ellowish-green, the tip 

 intenna darker, the eye blai kish, the anterior portion of the 

 abdomen dark-green as tar as a line drawn between the 

 which scarcely project above the surface oi the bod) ; the whole of 

 the abdomen is surrounded along its edge In a marginal bordei ol 

 short pure-white waxy Glami I 3 of which sometimes occur 



also on the sides of the thorax. In the winged adult the general 

 colour is dull-green with a dark area on the abdomen correspond- 

 ing to that in. the immature form ; prothorax yellowish with a pair 

 of ill-defined brownish spots ; eyes reddish; antennas black ; legs 

 pale-greenish infuscated at apices of segments. When disturbed, 

 the immature insects elevate their bodies at right angles to the 

 g surface in a very characteristic manner. 



Foodplants.- -Bamboo (Dendrocalamus giganteus). 

 Status. Apparently a minor pest, doing little harm even when 

 in large numbers, although the drain of plant-juice must then be

 the appearance of garden-grown bamboos.
