CASE-MOTH OF THE OEANGE. 81 



others growing near also, a good spraying. If this be 

 properly done the poison, with the addition of a handful 

 of flour, will adhere to the whole surface of the plant 

 treated, thereby killing all the grubs which are feeding 

 upon the tissues of the leaves. One trial or two at most 

 will convince any one as to the efficacy of this treatment 

 for insects of this class. 



When vines and very young trees are attacked, and 

 the foliage of which is tender, reduce the strength of the 

 mixture to, say, 1 part to 200 gallons of water. Repeat 

 this dose for a couple of times, say at an interval of four 

 or five days. When the garden is small, hand-picking 

 may be resorted to, although this is a tedious and often 

 costly method. A similar result may be obtained by the 

 use of the so-called White Hellebore, Veratrum alburn^ 

 if the following directions are carried out: — 1 lb. White 

 Hellebore; 2 lbs. soft soap; handful of flour. Mix all 

 together, let stand for one hour, then add 35 gallons of 

 water, and spray as directed. 



It will be understood, of course, that both these spraying 

 materials, the former especially, are poisonous, so that 

 care and precaution must be taken against accident, but 

 with ordinary care they may both be used with perfect 

 safety both to the tree and fruit. 



A very curious matter connected with these stick-nests 

 has just been brought under my notice, viz., that at a 

 good elevation, on the branches of some Eucalypti growing 

 in the Cheltenham district, a large number of the 

 suspended cases have been found to have been split or 

 rather torn open whilst in that position. How this could 

 have happened is a puzzle to me, as it is somewhat of a 

 difficult matter to tear open the cases even where they 

 are removed from the tree, and most birds would appear 

 to be unable to tear them open, especially when in a 

 suspended position. 



This is a singular enigma that we must try to solve, as 

 there may be an enemy to these insects, which up to the 

 present time has escaped our observation, and which may 

 be turned to some good account.
