 This species occurs throughout North- West Irdia on peach and is 

 also found on Ageratum comjzoides. 



It is one of the worst insect pests that the peach-grower has to con- 

 tend against in Northern India. The leaves are contorted into pseudo- 

 gdls and the trees become sickly and unsightly. The leaves appear 

 closely crowded and never expand fully. They turn whitish and in some 

 cases pinkish. It is found with Myzus persicm on the same plant. 



Lachnus pyri, Buckt. 



South Ind. Ins., p. 503, f. 391 ; Proc. Second Entl. Meeting, p. 247. 



This species occurs commonly on pear in Ootacamund and the 



Shevaroy Hills and Ceylon (Hills), but apparently does not extend into 



Northern India. It occurs in masses on the stems and branches and 



is easily dealt with by brushing or spraying.
