The editors will thankfully receive news items and other matter likely to be of interest to sub¬ 
scribers. Papers will be published, so far as possible, in the order of reception. All extended con¬ 
tributions, at least, should be in the hands of the editor the first of the month preceding publication. 
Contributors are requested to supply electrotypes for the larger illustrations so far as possible. Photo¬ 
engravings may be obtained by authors at cost. The receipt of all papers will be acknowledged.— Eds.

The recent discovery of large areas with a gipsy moth infestation of 
some years’ standing and a similar find in relation to the European 
corn borer raises a series of interesting questions. Those familiar with 
the subject may recall that the gipsy moth maintained itself in this 
country practically unnoticed for twenty-two years, and the evidence 
at hand indicates that the European corn borer was probably intro¬ 
duced some ten years before its recognition. Furthermore, these 
records are by no means peculiar to these two insects or to certain 
infestations by one or both. The facts are that outbreaks by unknown 
insects largely escape attention unless of marked severity and even 
then may not be brought to official attention with desirable prompti¬ 
tude. This is due to two causes. It is frequently very difficult to 
decide in advance the true status of an importation, and in not a few 
instances the observer, if there be one, is unable to distinguish between 
an unusually abundant native species and a newcomer. The assist¬ 
ant farm bureau agents, working in some counties of New York state, 
will render material assistance along these lines since they give special 
attention to insect pests and plant diseases. County farm bureau 
agents are extremely valuable in the early detection of new insect pests. 
There should be, however, wider appreciation of the important part 
played by insects and this can be brought about only by more general 
knowledge of the group, not so much along systematic lines as in 
popular and practical ways. The general public should appreciate 
more fully the economic status of the group and come to have a sym¬ 
pathetic appreciation of the part played by the hexapoda in the scheme 
of nature. Not all are willing to become entomologists and it is not
