ground, gas lime should be thickly spread upon the surface and 
plowed under in autumn, and allowed to remain all winter in the 
earth, a second dressing ‘being also applied to the surface immedi- 
ately after plowing. 
The value of this application is attested by Mr. J. H. Hale of 
Connecticut, who writes me that he has used gas lme to help rid 
the land of grubs, and that following this, he has had grand crops 
of berries. 
The use of flour of sulphur for the purpose of repelling the grubs 
from newly set plants is also recommended by Mr. Hale. He says: 
“In a field full of them we saved all of our strawberry plants by 
mixing flour of sulphur in and around the roots of each plant at 
time of planting; and in some rows where this was not done, most 
of the plants were destroyed.” 
Ter GoupsmitH BEETLE. 
Cotalpa lanigera, Li. 
Order Conzoprzra. Family Scarapaipm. 
[Plate VII, Fig. 2 and 3.1 
The larva of this species is so extremely similar to the common 
white grub described in the preceding article, that the two are 
doubtless ordinarily confounded. 
It is, however, usually much less abundant than the preceding, 
alt hough it sometimes occurs locally in destructive numbers. The 
larva 1s known to feed upon the roots of clover as well as upon 
strawberries, and it is probably an indiscriminate feeder. 
The beetle (Plate VIT, Fig. 2) is about nine-tenths of an inch long, 
broad oval in shape, of a lemon-yellow color above, glittering like 
burnished gold on the top of the head and thorax; the under side 
of the body is copper-colored, and thickly covered wiih whitish wool ; 
and the legs are brownish yellow, cr brassy, shaded with green 
These fine beetles begin to oy ear in Massachusetts about the mid- 
dle of May, and. continue generally till the 20th of June. In the 
morning and evening twi a they come forth from their retreats, 
and fly about with a humming and rustling sound among the 
branches of trees, the tender leaves of which they devour. Pear 
trees are particularly subject to their attacks, but the elm, hickory, 
poplar, oak, and probably also other kinds of trees, are frequented 
and’ injured by them. Duiing the middle of the day they remain 
at rest upon the trees, clinging to the under sides of the leaves, 
and endeavor to conceal themselves by drawing two or three leaves 
together, and holding them im this position with their long unequal 
claws. In some seasons they occur in profusion, and then may be 
obtained in great quantities by shaking the voung trees on which 
they are lodged in the daytime, as they “do not attem pt to fly when 
thus disturbed, but fall at once to the ground.*
