to six gallons of water, and applied in a spray in the same man- 
ner as the kerosene emulsion. In addition to this the vines should 
be frequently examined and the affected leaves plucked and 
destroyed. The above remedial measures are suggested because 
they have proved beneficial in dealing with other similar insects. 
Tue Srripep CucumBeR BEETLE. 
(Diabrotica vittata, Fabr.) 
This little yellow and black beetle has been very abundant on 
Long Island this past season. In the vicinity of New Lots, 
Jamaica and Queens it was found doing much damage to cucum- 
ber vines. It feeds freely on many other of the cucurbitaceous 
plants, however, and has been for some time a very troublesome 
pest in Michigan, Ohio, Iowa and other of the central and west-. 
ern States. | 
Although very generally known, I am 
inclined to think that this beetle is little 
suspected by Long Island farmers in gen- 
eral as being injurious. It belongs to a 
very large and important order of insects 
known as the Coleoptera, but to a differ- 
ent family from that to which the boreal 
lady-bird beetle belongs. The mature 
insect is not large, being only about one- 
fourth of an inch in length. It is yellow 
in color, with two black stripes running 
the whole length of each wing cover and .

wing covers come together. The larvee 
are about two fifths of an inch long, very slender, white in color, 
with a brown head and obtuse proleg behind. Fig. 3 phd Sh oe

Life-History and Habits. 
The beetles appear early in the spring and, for the time being, 
are to be found feeding on a great variety of plants. As soon 
as cucumber vines appear, however, they desert everything 
else and attack these, at times even burrowing into the ground ~ 
to meet the tender shoots. The eggs are said to be laid below 
the surface of the ground, usually on the roots of the host plant
