has become brown and dead, and the leaves themselves have 
eventually dropped off whilst still green. Sometimes but one of 
these bodies is present on a leaf ; oftentimes,^ however, five 
or six ; and as for size they vary from Jiii. to 2in. across. So 
prevalent is the afteetion that in many eases trees have been 
completely denuded of their foliage. Some of them have, 
however, been fortunately able to develop terminal shoots and so 
commence afresh their vegetative growth ; others, too debilitate 
through loss of their assimilative organs to do so, have emitted 
frah lateral offsets, which in turn have either become covered 
with a curious dwarfed foliage or have even also perishe . n 
many trees, as a consequence, the symmetry of form has been 
permanently affected ; in all, the growth has been serious y 
retarded. 
This mjury is due to the attacks of a small transparent 
four-winged snout-hearing jumping insect referable to the order 
Homoptera and the genus Psylla, measuring obouttwo lines m 
length. Its inimical relation to the fig tree, on winch 
subsists, will be seen from the following particulars concerning 
its life history.
