lars with a repellent insecticide, such as whale oil soap or the 
carbolic soap wash. These applications should be made about 
the first of July and probably repeated toward the latter end of 
the month, the time for second treatment depending somewhat 
on the amount of rain. 
Nun moth, Psilura monacha Linn. Our attention has 
recently been called to the reported presence of this European 
insect at Brooklyn N. Y. According to the published account,’ 
Mr George Franck stated that, on looking over the small collection 
of a local collector during the summer of 1901, he found among 
other material five individuals of this species, which he identified 
by comparison with European specimens, of which he possessed 
anumber. The collector in question had no communication with 
others than Mr Franck, from whom he obtained material in 
exchange, and, when he was questioned regarding this species 
and its occurrence, Mr Franck was assured that the specimens 
had been captured at light in Brooklyn. No other person who 
had been consulted in regard to this species knew anything of 
its occurrence in that vicinity, and it was put down as an acci- 
dental importation, which is possibly true. The person who 
made the capture resides in a district where there are numerous 
lumber yards, and shipping is quite extensive. The location is 
described as being around North 2d street and Metropolitan 
avenue, near a creek which adjoins that portion of the bay run- 
ning through the eastern part of Brooklyn. Since only five of the 
insects were taken, it may not be that the species has been intro- 
duced; but, as pointed out by Dr Howard, we may have here a 
parallel case to that of the gipsy moth, Porthetria dispar 
Linn., which was known to be actually introduced into this coun- 
try 25 years before it attracted the attention of economic ento- 
mologists. The two species are related and have similar habits; 
and there is reason to believe that, if this species does become 
permanently established in the vicinity of New York, it will 
prove a serious enemy and perhaps be even more troublesome than 
the gipsy moth. The latter was established inland, while the 
nun moth, if it has obtained a foothold, will probably spread to 
the immediate vicinity of water ways on either side. This feature
