THE HICKORY TUSSOCK-MOTH. 
(Halesidota carye Harr.) 
At Waterville and vicinity | found a number of caterpillars, when 
fully grown about one inch or a little more in length. The head and 
under side of the body are black; the upper part, so far as can be per- 
ceived, is white, sprinkled with black dots, and with transverse lines 
between the rings. They are covered with short, spreading tufts of 
white hair, with a row of eight black tufts on the back, and two long, 
slender, black pencils on the fourth and tenth rings. The tufts along 
the back are so close together as to form an apparently unbroken ridge 
of short, dense, and somewhat bristly hair. The hair on the front part 
of the body is longer than the rest and overhangs the head. These 
caterpillars are full-grown about the 10th of September, spin a cocoon 
in some crevice, under stones or in heaps of rubbish, and transform into 
a brown chrysalis. In June following the moths appear. They expand 
from 14 to 2 inches; the fore wings are long, pointed, of a pale ocher- 
yellow color, finely sprinkled with brown dots, and crossed by four 
irregular rows of large white and semi-transparent spots. 
The caterpillars do not seem to feed very heartily, as even where 
they were most plenty the leaves were not noticeably eaten. They are 
nowhere very abundant, have not been known to do any serious injury, 
and are probably kept in check by the fact that before they are ready 
to spin up the vines are cut down, and then, when forced by want of food 
to make their cocoons in the piles of vines, they are destroyed when 
the vines are burnt. 
THE HOP PLANT .LOUSE. 
(Aphis | Phorodon| humuli Schrank.) 
This insect is well known to all growers, and was especially injurious 
during the past season, the hops being rendered universally of an infe- 
rior grade,and many spots so greatly injured that they were not picked. 
For many years past the hops have been more or less injured by lice, 
but this year they were especially abundant, the universal testimony of 
all growers being to the effect that never before had they known of such 
injury caused by them. Nothing at all was done to combat them, the 
worst infested parts of the yards only being first picked, sometimes a 
little before fully ripened, and most of the energy and ingenuity being 
devoted to bleaching out of the hop all trace of the ‘“ mildew” and 
‘* rot” caused by the insects. 
As in respect to these insects my notes are full, I will simply tran- 
seribe them. 
June 21.—At Herkimer, in Mr. Pine’s yards, examined carefully for 
aphids, but find no traces of them. Mr. Pine says his low-lying yards
