444 ARBELA TETRAONIS. 

Mr. Fischer has discovered that the larva feeds upon the 
bark of many grove and avenue trees in the vicinity of the 
attacked plantations in Chatrapur. He mentions the . 
following :—Acacia leucophloea, Acacia arabica, Holarrhcena 
antidysenterica, Anogeissus latifolia, Millettia auriculata and 
Eucalyptus globulus (one). 
Protection.—My inspection at Chatrapur enabled me to suge 
gest a remedy to Mr. Fischer. We have seen that larve are 
to be found between December and June, and that during 
this period or portions of it they are to be found in covered 
ways on the bark of the trees, only leaving these to bore down 
jnto the wood to change into the chrysalis state. I would 
suggest that the larve be searched for and killed during the 
period they are feeding upon the trees. The covered ways 
are very visible, and each fresh one should be carefully pulled 
to pieces and the larva taken out and killed. Boys in charge 
of a watcher could be put on for this purpose. The watcher 
would first count the number of covered ways upon a tree and 
then send up the boy to take out the caterpillars, and the 
number of these latter should tally with the number of covered 
ways counted and the boy be paid accordingly. The covered 
ways should be pulled off the bark only after the caterpillar 
has been taken out. Inthe cases where they coalesce the 
operation should be done carefully, so as to make certain of 
taking all the caterpillars. If any of these latter escape they 
will soon construct a fresh. covered way and continue their 
Cepredations. A kerosene tin with some kerosene mixed with 
water at the bottom will form a convenient receptacle in which 
to throw the caterpillars, This work should be started as soon 
as the new covered ways are seento be making their appear- 
ance on the trees; and if done carefully and systematically 
throughout the plantations, I see no reason why it should 
not be possible to stamp out this pest or reduce its numbers 
to such proportions as will no longer endanger the plantations.*

* Since this was written Mr. Fischer has shown that this method is not 
sufficient when the attack is on the scale of the 1903-04 one. Such, however, 
will in all probability be very tare and ordinarily the above measures, if 
undertaken in a thorough and efficient manner, should suffice to keep the 
plantations clean,
