“ American Blight ” or “ woolly louse ” is stated to occur in South 
India and to have been extremely destructive ; a great deal has been 
written about this pest in temperate 
climates, and what is known of it 
in India will be found in Indian 
Museum Notes, II, p. 52. 
Buckton described Rhizobius juju- 
bee from the roots of ber (Zizyphus 
jujuba) and also recorded the 
European rose aphis (Siphonophora 
MACULATUS 
Fig, 521 —Chaitophorus 
Wings. 
rosce) from India (British Aphides, Vok 
IV). Though occurring outside the 
limits of the plains, we may notice the 
gall-making aphid on Pistachia terebin- 
thus described by Buckton as Pemphigus 
cedificator (I. M. N., Ill, 71) as well as 
P. napeeus , Buckt., and P. immunis , 
Buckt., on Poplar and Aspen in the 
Himalayas (I. M. N., IV, 50). Oregma 
bambusce, Buckt., is described as at¬ 
tacking bamboo in Debra Dun. (I. M. 
N., Ill, 87.) 
Buckton also described Chaitophorus 
maeulatus (I. M. N., IV, 277), which 
attacked lucerne in Jodhpur. It is a 
frequent pest to lucerne in other parts of India where this crop is grown 
for fodder. The following is a list of definitely recorded or identified 
species
