Rulelinw. 

 Popillia Morion. Xi'WJii. This little shining green insect is a pest 

 in its larval stage on cinchona roots in Dodabetta. 



Melolunthince. 



(1) Ilololrichia rcpciila, Sharp. This was found in large numbers 

 in the soil in the cinchona plantations at Dodabetta. The grubs injure 

 the roots of young cinchona plants. 



(2) Holotrichia sp. This is of the same general appearance as //. 

 refetita but is slightly smaller. This was found in gi-eat abundance 

 in the cinchona plantations at Dodabetta, in the ground, awaiting the 

 South- West-Monsoon to fly out. These are injurious to cinchona seed- 

 lings in the larval stage. 



Both these species of Holotrichia were caught in large numbers in 

 light traps. 



From individuals of both species confined in cages it was found 

 that they lay small white eggs singly and that each female can lay about 

 100 eggs. 



(3) Holotrichid rvjojlara, Bi s. This was taken near roots of orange 

 plants at Coimbatore. It is believed that the grubs of the species ate 

 off the bark, just below ground level, from orange plants and caused 

 their death. 



(•1) Serica nilgirensis, Slip. The larvte of these were found in com- 

 pany with those of the two Holotricliias mentioned above at roots of 

 cinchona seedlings. 



It is hoped to do more work on the group, now that it is safe to trans- 

 mit specimens to, and receive comniunications from, experts abroad. 



This paper might have been taken earlier when we were discussing Mr. Fletcher. 

 crop-pests. There does not seem to be much systematic work in it, 

 although the title was communicated for inclusion in the programme 

 under the head of Systematic Entomology. 



In Sylhet I found the bark of orange-trees eaten away near the Mr. Ghosh, 

 ground by something. I could not associate this with an insect. It 

 might have been due to some bacterial or fungal disease. 



At Coimbatore we were able to observe fresh cuts from day to day Mr. Isaac. 

 and the only thing found near these were the Melolontliid grubs. 



Species of Holotrichia are common girdlers and are also accom^^anied Mr. Beeson. 

 by Adoretiis and one cannot differentiate their work. I am not, how- 

 ever, in a position to add any definite observations.
