THE HOP FLEA-BEETLE. 91 
abouts, and thrown into hot water, and after drying will be available 
for use in other seasons. 
If, with another year's experience, we could ascertain how best to 
control the insect, either by killing the beetles with arsenate of lead 
or other arsenical, kerosene emulsion, or whale-oil soap, or by destroy- 
ing the larva? in the ground, the problem would be partially solved. 
One, two, or perhaps even three of these remedies might be used in 
combination and excellent results obtained. In any ease, if we can 
partially control the insects by any one of them we should not forget 
that cultural remedies, and especially clean culture, are the most 
valuable remedies that can possibly be employed against insect pests. 
Indeed, with many species, if cultural practices were properly fol- 
lowed out, with the cooperation of our neighbors, insecticides would 
in the course of time, after the balance of nature had been restored, 
seldom be needed save in case of severe outbreaks, which are likely 
to occur more or less spasmodically with most of our noxious insects. 
LITERATURE. 
A complete bibliography of this species is appended and only a 
brief review of published accounts need be given. The original 
description of the species appeared in 1847, 1 and it was not until 
twenty years later that we had any record of the insect's habits. In 
1867 Fitch 2 wrote a two-page account regarding injury to cucumber, 
rhubarb, and radish, furnishing notes on a parasitic natural enemy. 
In 1884 our first account of injury to hops, a brief one, was written 
by Dr. J. B. Smith. 4 These accounts were followed by one from 
Piper on injuries to certain truck crops in Washington State in 1895 
and by Doane s of similar injuries in 1900. The writer 7 noted the 
abundance of the species on rhubarb near Washington, D. C., in 1897. 
Forbes and Hart have given a brief account of the insect from the 
standpoint of its injuries to sugar beet in Illinois, and Fletcher 10 - 11 
published f wo accounts of the species in 1904 and 1907, respectively. 
In 1908 ws s published II. J. Quayle's article, 12 in which first mention 
is made of the larval habits of the insect.
