Reports of the Honorary Consulting Entomologist. 327 
have been given of the 
generally believed to appear first in the form of flj (that is, of 
the winged aphis) on the up])ermost shoots and leaves ; but 
there are also a few notes of the so-called " lice " being first 
seen, also of their being observed in the ground, and creeping 
up the stems. 
In a case of isolation of a hop-plant, which was carefully 
enclosed from outer attack, it remained quite clean for about 
three weeks or more, and afterwards was so badly infested that 
it was almost killed. I have been confirmed by Mr. Buckton 
in the certainty of one kind of aphis, which infests the plum, 
being the same as the hop aphis ; and I have also received 
specimens of the common nettle with aphis multiplying on 
the leaves, which differed in no way that 1 could see from the 
hop aphis. 
The subject of dealing with hop aphis attack is one which 
can only be judged rightly of by those practically acquainted 
with the matter, and I am therefore arranging the notes for 
distribution amongst the contributors, who may then help to 
give further information. 
In the course of inquiry, notes 
hop frog-fly, jumper or cuckoo-fly 
(Euacant/ius), of which two kinds at Fig.;;3.— T^e Hop Frog-flij. 
least infest the hop, and of which 
the starting-point was wanted. It has 
been found in its earliest stage 
coming up from the earth round the 
hop ; therefore, any application which 
would keep the cuckoo-flies from 
going down or laying their eggs on 
the surface in autumn, or any treat- 
ment which would clear esss or larvae 
from round the stems, or would pre- 
vent them getting up the stems in 
early summer, would be very ser- 
viceable. 
jNotes on many other attacks have 
been sent in from practical agri- 
culturists ; and among those to fruit and bush fruit it may 
be remarked that a large proportion would be much lessened 
by paring off about two inches of the soil under the attacked 
trees during winter, and so disposing of it that the chrysalids 
or cocoons within it should be destroyed. 
Inquiries have also been sent regarding other crop pests, as 
false wireworms or millepedes, and field slugs, to all of which 
I have attended carefully, and have satisfaction in mentioning 
that sometimes, and especially with regard to slugs, I have 
1, Larva; 2, Fly ; both magniBed. The
