It is not expected that the above recorded flights in cities and) 
villages will be followed by extensive injuries another season, since 
it is very probable that the English sparrows destroyed many of 
the adults before there was an opportunity for the deposition of

Spruce gall aphid (Chermes abietis Linn.). This intro- 
duced, widely distributed species has been the cause of an unusual 
number of complaints in New York State. Mr John Herliky, 
arboriculturist of Brooklyn, writing under the date of June 22d 
stated that many Norway spruce trees throughout Prospect park, 
and in fact in different parts of that section of the State, have been

were found to contain a few of the characteristic galls of this in- 
sect and, in addition, an apparently undescribed injury. Numerous 
subglobular, aborted buds were found here and there at the base 
of the branches or at the base of new growth and on investigation 
were found to contain numerous small, light brown aphids. It is 
probable that these aphids entered the developing buds the preced- 
ing year and, on account of their abundance, prevented the usual 
growth and the development of the normal type of gall. An ex- 
amination, at this time, of spruces in Albany showed that these trees 
likewise, in addition to the typical galls produced by this aphid, 
bere the subglobular dead buds inhabited by numerous aphids de- 
scribed above. An examination of infested trees in Albany the 
latter part of September showed that the dead buds described
