INSECTS DAMAGING ORANGE TREE. 125 



above the wound, and cover over with sand. Fin- 

 ish with a top-dressing of fresh wood-ashes or 

 slaked lime. If the tree is not too far spent it 

 will send out young roots above the wound and 

 finally recover. 



Another insect to be noticed resembles the squash- 

 bug, and is called by the entomologist of the De- 

 partment of Agriculture Euthoctha Galeator. This 

 insect is very bold in its attack. I have watched 

 them frequently in their operations as they were 

 lying in the hot sun basking, while their probosces 

 were inserted in the tender shoots. I have held my 

 magnifying-glass within a half or three quarters of 

 an inch from them, and had the finest opportunity 

 of observing the operations of this bold enemy of 

 the orange. I have seen the tenderer shoots wilt 

 when the insect was sucking them, from the ex- 

 tremity to the point at which this insect had insert- 

 ed its proboscis. As this insect is large, the injury 

 inflicted by it is speedy. But when the shoot is 

 older and more vigorous the effect is very similar 

 to that produced by die-back. These insects are 

 more apt to 'attack trees starting young shoots at 

 periods of the year when the grove is not generally 

 making new wood. As they cannot pierce the old 

 wood they seek for the tenderest. This accounts 

 for the impression that stimulating or forcing a tree 

 produces the die-back. 



The Euthoctha Galeator is fond of concealing 

 itself under litter of any kind during the night or
