METHODS OF CONTROL. 
Several remedies were tried in Colorado during the year of greatest 
infestation there with satisfactory results. These included Paris green 
and kerosene emulsion. Both killed the insects, checking their num- 
bers for the following year. Paris green was applied in the form of a 
spray and dry, mixed with flour. Used with flour it cost about 80 
cents an acre. Two sprayings with the liquid preparation were found 
to be most effectual. 
When this species occurs in fairly injurious numbers the remedies 
that have been specified should be sufficient. When it is unduly abun- 
dant, however, army-worm remedies should be applied. The latter 
form of remedies is discussed in Bulletin No. 29 (n. s.), a copy of 
which will be furnished to anyone desiring it. 
NOTES ON WEBWORMS. 
During the last two years three species of webworms that occur in 
gardens and do more or less injury to various crops have been reported 
as the cause of damage in various parts of our country. These are the 
garden webworm, beet webworm, and imported cabbage worm, each of 
which will be considered under a separate heading. 
THE GARDEN WEBWORM. 
(Loxostege similalis Guen.) a 
The reported injurious abundance of the garden webworm during 
the year 1900 in localities in three different States indicate that this 
species was somewhat generally destructive in that region that year. 
It is rather singular that, although the insect is widely distributed, real 
injuries by it appear to be confined to the States bordering the Missis- 
sippi River in the South. Some of the notes given show that it has 
even a longer list of food plants than have } T et been credited to it. 
May 14, 1900, Mr. J. D. Mitchell, Victoria, Tex., reported this web- 
worm as abundant in his vicinity, where it was known locally as the 
grass worm, a name which it shares with the better-known grass worm 
or fall army worm (Zaphyg ma frug ijierda) . Its favorite food in that 
a In early works this species has been generally referred to Eurycreon rantalis Guen., 
and now to Phlyctxnodes similalis Gn. The following synonymy is credited by Sir 
G. F. Hampson (Pr. Zool. Soc. Lond., p. 210, 1899), in addition to eight names 
bestowed by Walker: 
Phlyctxnodes similalis Guen. Delt. & Pyr., p. 405. 
Nymphula rantalis Guen. Delt. & Pyr., 405. . 
Botys posticata Grote and Rob. Trans. Am. Ent, Soc, 1, p. 22, pi. 2, f. 25. 
Eurycreon communis Grote. Can. Ent., ix, p. 105. 
Eurycreon occidentalis Pack. Ann. X. Y. Lye, x, p. 260. 
The list of "Walker's names includes: Ebulea murcialis, Botys Ureal is, B. siriusalis, 
Scapula nestusalis, crinisalis, thoonalis, and diotimealis, and Nephopteryx intracteUa.
