up and the queens destroyed by pouring a few ounces of the liquid into 

 the galleries, or into a hole made by a stake driven as close to the nest 

 as possible. The hole should then be closed with earth to insure perco- 

 lation of the vapor through the soil. 



Ashes, Lime, and Sulphur are without effect in protecting orange trees 

 from the attacks of Termites. In the cases where these substances have 

 seemed effective in driving them away the result has been accomplished 

 simply by the disturbance to their mines and exposure to the drying 

 action of the air. 



Ingrafting Scions. Trees completely girded by Termites may be saved, 

 it' taken in time, by inarching scions between the root below and the 

 stock above, thus ivstablishing the connection between the two. The 

 tree will in time restore the eroded bark, and the scions may be allowed 

 to remain or may be afterwards cut out. 



Supplementary stocks may also be planted close to the injured tree, 

 and grafted in above the girdled portion, to sustain the life of the trunk 

 and enable it to restore the severed connection. A poultice of mud and 

 cow dung, applied to the injured part, will protect it and materially as- 

 sist the formation of new wood and bark. 



CALOTERMES CASTANEUS. 



A second species of Termite, somewhat larger than Termesflavipes., but 

 otherwise closely resembling it, has been found in decaying branches 

 and stumps of orange; but as far as its habits have been observed it is 

 a tree-inhabiting species, seldom forming very large colonies, and not 

 likely to do injury to growing plants, as it prefers very dry wood, and is 

 most frequently found in dead branches from the tops of forest trees. 

 Should it prove injurious to the orange it will probably require the same 

 treatment as the related species.

 THE COMMON ORANGE SAWYER. 



(Elaphidion inerme Newman.) 

 [Fig. 47.] 



The larvae of this beetle are cylindrical, whitish, fleshy grubs or 

 sawyers, with rudimentary legs, which cannot be of much assistance to 

 the animal in moving about, and a pair of strong short jaws. As with 

 most borers of this family, the head is small and can be withdrawn en- 

 tirely into the body. The first body-joint is somewhat enlarged, and
