Attack by this species to pole Lima beans at St. Elmo, Va. , was 
reported by Mr. Pratt, August 27 and later in 1900. It seems that 
even a single boring in a pod of beans is enough to insure injury. He 
estimated that about 25 per cent of the crop of that vicinity was 
damaged. 
An illustrated account of this insect, entitled "The gray hair-streak 
butterfly and its damage to beans" was published in Insect Life (Vol. 
VII, pp. 351, 355). 
It is illustrated in its various stages in the accompanying figure 24. 
A natural enemy of this insect has been observed in a small ichneu- 
mon fly Anomalon pseudargiole How. 
This species seldom does very severe damage, hence little precau- 
tion need be observed in the treatment of it early in the season. It 
would be well, however, to destroy all affected bean pods, that the 
insect may not develop and do injury in after years. 
The Bean Leaf-beetle (Oerotoma trifurcata Forst.) — This insect has 
already been reported by Professor Johnson in Bulletin No. 26 (n. s., 
p. 81) as having been very destructive in 1900 to wax and Lima beans 
throughout the trucking area of Maryland. 
May 11, of the same year, the writer found this species at work on 
bean at Cabin John, Mel., doing, it would seem, the greatest damage 
ever observed in the East. Not a single leaf had escaped its ravages: 
all were pitted full of large holes or had been stripped to the midrib. 
The following day Mr. Henry Olds, of this Department, reported 
this insect injuring bean at TVoodside, Md., and Mr. Pratt noticed the 
same insect at work on beans at St. Elmo, Va. 
May 26, Mr. B. M. Hampton sent specimens from Peacocks Store, 
N. C, with report that this beetle was known locall}^ as the ''terrapin 
bug" (a name which it shares with Murgantia histriondca), and that it 
was a perfect nuisance, doing much injury to snap beans by eating- 
holes in the leaves. 
A second visit was made to the infested garden at Cabin John June 
12, a month after infestation was first noticed. The rows of beans 
that had been first planted and that were noticed to be most injured 
were practically ruined. They had not made such good growth as 
other rows planted later, and many of the leaves had dried up and 
fallen ofl. The later rows, though they had made better growth, 
looked, as an observer remarked, "as though they had been shot full 
of holes from a shotgun." . 
The Lima-bean Vine-borer (Monoptilota mibilella Hulst.). — This spe- 
cies, an account of which was given by the writer on pages 9-17 of 
Bulletin No. 23, n. s., made its appearance the past year on Lima 
beans, and in a new locality. August 27, 1900, Mr. Pratt reported 
the larvae at work on pole Lima beans at St. Elmo. Va., and late 
in September found that the same species was working on bush
