have been taken so frequently upon that plant, and under such pecu- 
liar circumstances, that they, too, may preve to beits enemies. Among 
these latter I would mention several of the Eleodes, one Collops, and 
several Diptera. 
REMEDIES THAT CAN BE USED AGAINST BEET INSECTS. 
It will be quickly seen by any one who has taken the pains to go 
over the foregoing list, that in nearly every case, at least so far as men- 
tioned here, the insect enemies of the beet are identical with those that 
work upon our common garden weeds, or else they are such as are very 
general feeders. It will also be observed that most of them are 
leaf-feeders; ¢. ¢., they nearly all attack that portion of the piant 
above ground. These being the facts in the case, the remedies that at 
once suggest themselves are simple. A spray of some kind scattered 
over the plants will be effectual as well as economical. The beet tops 
are seldom utilized for food, either for man or beast. Hence for pro- 
tection against insects with gnawing mouth parts that attack them an 
arsenical spray can be used, whilst for such as receive their nourish- 
ment by means of a sucking mouth the kerosene emulsion will answer 
the purpose. This latter remedy will also be effective against No. 27, 
as has been demonstrated by actual experiment by at least one of our 
correspondents, who writes that “The kerosene emulsion which you 
directed me to try on my beets against the flea-beetles was a perfect 
success.” 
A direct as well as useful remedy is the careful destruction of all 
such weeds as furnish food for the same insects that attack the beet. 
Clean culture in this case becomes doubly necessary. First, to prevent 
the appropriation by the weeds of nourishment that should be taken by 
the beets, and secondly, to give less room for the propagation of inju- 
rious insects.
