HOPS. 
maggot to be the early stage of the P. attenuates, which in such case 
we might perhaps more conveniently call the Hop Cone or Strig 
Beetle. 
1 and 2, Tooth-legged Flea Beetle, Clicetocnema concinna, nat. size and magnified; 
3, hind leg, magnified. 
With regard to the habits of this maggot, Mr. Goodwin, writing 
from Crancli, Sevenoaks, mentions that attack from it has been very 
general in that neighbourhood, where the attack has ruined several 
pieces of Hops. He observes that it pierces into or rather is bred in 
the “ strig ” or stalk of the cone or flower, where it eats its way up 
the inside of the stalk, which causes the Hops to wither and turn 
brown. The maggots varied in number in one strig, but one or two 
were the average. In the earlier part of September these maggots 
were very numerous, but at the date of writing, September 27tli, they 
had disappeared—“they drop out into the earth after eating the 
Hops.” 
Specimens forwarded to me by Mr. Goodwin and from other 
localities, all showed the burrows of the maggots very plainly, but in 
all cases the maggot was absent, which confirms the observation 
of Mr. Goodwin and the conjectures of other observers, as to this 
grub leaving the Hop to change to the chrysalis and beetle in the 
earth. 
Mr. R. Cooke forwarded specimens of Hops similarly attacked, 
from Detling, near Maidstone, mentioning that the altered colour was 
from the attack of a maggot, which channelled out a home for itself 
in the stem which forms the centre of the cone. The attacked Hops 
begin to go off from the tips, and the stem which supports the Hop 
dies back to the main branch. If in the next season some of the 
infested Hops were placed on earth in a flower-pot or box (tied over 
with a piece of stout muslin to prevent any escape), whatever beetle 
this maggot turned into might be secured when it came up from the 
earth and identified. 
In the case of the maggots of Psylliodes chrysocephalus (a nearly 
allied beetle), which I have observed tunnelling the flowering stems
