We have not seen this flea-beetle injuring the vines of cucur- 
bitaceous plants in Colorado. 
REMEDIES. 
Although the flea-beetles devour the tissues of the plants upon 
which they feed, the arsenites, London purple and Paris green, have 
not been very useful in destroying them or'preventing their attacks. 
From our own experience, we would put Buhach at the head of the 
list of remedies, if properly applied. To be of use, the pow^der 
should be applied dry before sunrise in the morning, while the 
beetles are cold, sluggish and damp with the dew of the night 
After the sun is up and the beetles have been warmed into activity 
they will quickly jump away from any attempted application. 
A strong kerosene emulsion, sprayed forcibly and thoroughly 
upon the plants early in the morning, will also be effectual in 
destroying the beetles. 
As the beetles feed on a great variety of plants, they can 
usually be driven from cultivated crops by a thorough application 
of lime, ashes or road-dust in the evening or early morning, while, 
the dew is still on. 
THE COLORADO CABBAGE FLEA-BEETLE. 
{Phyllotreta albionica Lee.) 
This is one of the smallest of the flea-beetles, measuring from 
l-15th to l-16th of an inch in length. It is uniformly black in 
color, with the first three joints of the antenna pale [Fig. 10]. 
Pig. 10. 
So far as we have been able to observe here, this is the only 
other flea-beetle that does serious injury to garden vegetables in 
Colorado. 
We have taken this beetle feeding on cabbage, radish, beet, 
mustard, cauliflower, horseradish, and the Pocky Mountain bee
