in keeping the beetles away. When plants were examined, the 
day following the treatment, the beetles were found feeding on the 
plants, and when disturbed, they hid themselves in the tobacco 
dust at the base of the plants. (These were Long Island “ cuck”’ 
beetles.) Possibly a good quality of snuff would be more effec- 
tive than tobacco dust, but it would be an expensive remedy. 
Road-dust, ashes, soot, charcoal, salpetre, cow-manure, hen- 
manure, burdock infusion, slug shot and “ bug death” are a few 
of the numerous measures often recommended which have no 
value except to frighten the beetles away from the plants at the 
time they are applied. 
CONCLUSION. 
From what has been given regarding the habits of the striped 
beetle, and the results of tests of different remedies, it will be 
seen that no one measure will give absolute protection to the 
vines of cucumber and melon. Furthermore, it will be seen that 
if Paris green, green arsenite or in fact any of the arsenites are 
used with Bordeaux mixture or with air-slaked lime, with the ex- 
pectation of killing the beetles, they will be failures. Hence, I 
recommend the use of squashes as a lure and as a poisoned bait, 
combined with the use of Bordeaux mixture on the cucumber vines, 
and in some cases, also combined with the use of covers. I also 
recommend the planting of squashes or beans in September for 
the purpose of poisoning as many of the beetles as possible during 
the fall. Green arsenite and Paris green can be, and frequently 
are, used with water for poisoning the squashes and beans, but as. 
the object of the latter is to kill as many of the beetles, in as short 
a time as possible, it is better to use the arsenites dry, for the 
simple reason that they can be applied stronger and not kill the 
vines as quickly as when used with water.
