62 LEAF-BUGS. 
marked with rather sparse scale-like tufts of yellow hair, which 
are readily detached, so that older specimens are smooth. 
The insects have been found but once in our state, injuring 
the sugar beets, but they may be much more common than is 
supposed, as they are difficult to capture, being able to jump 
many times their own length. They hop from the leaves of 
the infested plants like genuine flea-beetles. They are found 
upon many wild plants, but occur also in injurious numbers 
upon late potatoes, tomatoes, egg-plants, beans, peas, clover, and 
even grass. 
Prof. Popenoe was the first to give an account of their in- 
jury to beans in Kansas during the season of 1890: “Living in 
great numbers on the under side of the leaves of the garden 
bean, puncturing the tissues, and sucking the sap, and by these 
punctures causing the death of the tissues in small, irregular 
patches that appear upon the upper surface of the leaf as white 
spots. These two species are so nearly alike, so far as habits 
are concerned, that they may be noticed together. They op- 
erate mostly near the ground and upon weak, low-growing sorts. 
They sometimes do appreciable injury to the plant. The in- 
sects of both species are able to jump many times their own 
length, and when disturbed they hop from the leaves like flea- 
beetles. They have also been observed to feed upon red clover 
in the manner and with the effect described above.” 
Mr. Chittenden thinks that the most feasible method of treat- 
ment would be the use of kerosene in some of its forms. A 
spray of kerosene emulsion, as strong as the plant will bear 
without injury, would doubtless be effective in the destruction 
of the bugs in all stages, or they might be jarred from the 
plants upon which they are feeding onto sheets saturated with 
kerosene, or into pans of water on which a thin scum of kero- 
sene is floating. For the mechanical method of treatment it 
would be preferable to go over the infested plants early in the 
morning or late in the day just before dark, when the insects 
are less active than in the bright sunlight. 
Agalliastes associatus Uhler. (False Flea-hopper). 
This minute insect, illustrated in Fig. 51, Plate III, is easily 
mistaken for the insect just described. It is also very active and
