Tue CASTILLOA BORER AND THE ORANGE Boren. 
There is nothing to be said on these two insects which, mutatis 
mutandis, has not been said above on the coffee borer. 
Dr. Easmon says “two classes of borers affect these plants, one 
attacking them at the roots, the other at the branches. It would appear 
that the ‘operations of the latter are dependent upon those of the former, 
and that, as a matter of fact, they are inoperative until a certain degree 
of diminished vitality of the wood is reached.” This is probable, ‘and 
is in agreement with what has been suggested as possible, even if not 
likely, in the case of the coffee shrubs. 
The Longicorn beetle, Eunidia, is the stem-borer, and its attack is 
therefore to be regarded as secondar

Nothing is known to me of the habits of these insects, and, with the 
exception of Metallonotus denticollis, it is likely that their presence on 
d trees is of no importance. They probably bear the same 
relation to the injurious "—— beetles as saprophytie do to 
parasitic fungi.
