 ing from 50 to over 100 eggs. 



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 



eggs. 



Spruce gall aphid (C h e r m e s a b i e t i s 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 22(1 

 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, 

 bore 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
