80 Indian Museum Notes. [ Vol. VI, 



frightened the insects are said to drop off the leaves and to hide in 

 the furrows between the rows of plants. The beetles were said 

 not to have been found on irrigated land. They were reported from 

 the Cawnpur Farm towards the end of December 1902, when they 

 appeared in great numbers on almost every plant in the early 

 stages of growth. The insect is new to Indian Museum Collections. 

 Nothing further appears to be known about its life-history. 



Points in the life-history requiring further observation. 



1. Where are the eggs laid ? 



2. Where do the grubs feed ? 



3. How often do the beetles appear in a year, i.e., how many 



generations are passed through ?

 This insect was very fully described in the above quoted number 



of these notes. 



Juar stalks were found bored by a caterpillar in the rains in the 

 Central Provinces. The grub was said to do considerable damage 

 to young plants in seasons of light rainfall, but seems to be killed off 

 by heavy rain. The grub hollows out the interior of the stem and
