their nests with plant lice.^ Perhaps S. conesiogorum also nor- 

 mally makes its nest in such twigs and only occasionally accepts 

 galls. In any case, it is not a far cry from pithy twigs to pithy 

 cynipid galls. 



This species is, I believe, here recorded for the first time from 

 New Jersey. It was described from specimens obtained in Penn- 

 sylvania.- I am indebted to Mr. Rohwer for the identification of 

 the New Jersey specimen. 



NOTES ON THE OCCURRENCE OF SOME ECONOMIC 



INSECTS NOT HERETOFORE RECORDED 



FROM NEW JERSEY. 



By Harry B. Weiss, 

 New Brunswick, New Jersey. 



GracUaria azaleae Busck. 



This species has been noted in several greenhouses in northern 

 New Jersey. The small larvae turn over the tips and edges of 

 azalea leaves and feed therein causing them to turn black and die. 

 Pupation takes place in a silken, whitish cocoon usually attached 

 to the leaf near where the larva has been feeding. This insect has 

 also been taken in the larval and pupal stages on azaleas imported 

 into New Jersey from Belgium. As yet, it has not become a serious 

 greenhouse pest, probably because azaleas as a rule are not carried 

 over until the next season or grown by most florists. After being 

 forced, practically all are sold and fresh ones imported the next 

 year. 



Kaliosysphinga ulmi Lund. 



This saw-fly leaf miner was noted at Westfield, N. J., during the 

 summer of 1914, doing noticeable but not serious damage to the 

 foliage of elm trees. The mines were irregular and blotch like in 

 appearance. In Smith's 1909 list, it is mentioned only as being 

 sure to occur in New Jersey.
