and harlequin bugs on cabbage, and as they feed by suction they soon 
exhaust a plant by depriving it of its vital juices, causing it in time 
to wilt and perish. The distribution of the species extends from New 
Hampshire to the Gulf, and westward to the Pacific States. It is sub- 
ject to the same atmospheric influences as the true chinch bug, damp, 
rainy weather being unfavorable to its development. 
Bemedies. — The best manner of holding this bug in control consists 
in clean culture, keeping down all purslane, a favorite host plant, the 
careful cleaning up of crop remnants and other trash before winter, 
and the collection of the bugs when they occur in numbers in pans 
or pails filled with water and a thin scum of kerosene. The free use 
of kerosene emulsion and 
pyrethrum is also of value, 
the latter, though expensive, 
being efl&cient in small fields. 
THE MINUTE FALSE 
CHINCH BUG. 
[Nysius miniitus Uhl. ) 
According to recent re- 
ports emanating from sev- 
eral sources in Colorado, 
thisdnsect is of growing im- 
portance as a beet pest. It appears to be more particularly destruc- 
tive to beets grown for seed, the injury being accomplished by the 
bugs sapping the green seed, which in consequence dries up and fails 
to mature properly. 
It differs but slightly from the previously mentioned species, being 
a little smaller, measuring only about a sixteenth of an inch in length. 
Its distribution and its food habits appear to be practically the same, 
in fact additional study is necessary to determine whether the two 
forms are actually distinct species. 
Remedies. — It has been ascertained by beet growers that the flood- 
ing of infested fields causes the insects to leave, and the growing of 
mustard as a trap crop has given excellent results, precautions being 
taken that the mustard be not allowed to run to seed, as it is likely to 
become a pest itself. Other remedies advised for the common false 
chinch bug just considered are also applicable. 
THE GARDEN FLEA-HOPPER. 
{Halticus uhleri Giard. ) 
In recent years this minute black bug has been the occasion of con- 
siderable injury in various parts of the country. In 1890 it did dam- 
age to beans in Kansas, and in 1896 like injury was inflicted on red 
clover and other plants in Ohio. It is commonly seen in beet fields,
