Report of the Consulting Entomologist. 
infested plants were not more than about ten inches high, and one 
not as much as four inches in height, with the stem widened, flat- 
tened, and swollen at the base. This stunting of the stem, the side 
shoots being abnormally close together, and many of the pods 
stunted and distorted, appeared to be characteristics of the attack. 
The stem eelworins were present both in male and female state, 
also very numerously in larval condition in soft matter inside the 
stem. 
This stem eelworm is a minute, transparent, white threadworm, 
at its full growth scarcely more than l-25th of an inch in length,' 
and its greatest breadth may be said in a general way to be l-30th 
of its length. 
The treatment which has been already noticed as serviceable for 
prevention of eelworm attack to clover and oats will be equally

applicable for beans, and when infestation is present probably the 
dressings of sulphate of potash, or mixtures of sulphate of jjotash 
and sulphate of ammonia, etc. which have b^en found excellently 
successful in stopping attack, will be as serviceable for bean attack, 
if applied as soon as the first beginnings of deformed and stunted 
growth are observable. 
Another attack which has been very little noticed before, but 
which we now find sometimes does much harm in orchard growing, 
is that of a small insect, very much resembling a small froghopper, 
with apple-green body and four transparent wings. This is the 
apple chermes, or " apple-sucker," the Paylla mali scientifically. 
These Psyllas, or apple-suckers, I found, could run very well, 
and then, with a sudden skip, fly away. Their length is somewhat 
under the eighth of an inch. The general colour is apple-green
