FIELD NOTES 



Chermesinae 



Phylloxera c-vence Fitch. Abundant on hickory leaves at Roches- 

 ter and Georgetown. Galls along midrib or main veins and usually 

 near the margin of a leaf. Within were eggs, larvae and pupa ; none 

 alate at Rochester. Syrphus larvse were also common in the galls. 

 Stem females, eggs and alate adults were in the galls at Georgetown. 

 The eggs and stem females are very pale yellow, almost white; pupse 

 dusky yellow. 



Phylloxera c-fallax Walsh. Noticed at Rochester only on hickory 

 leaves. Many of the lice were alate ; galls abundant. 



Phylloxera intermedia Perg. Taken on hickory leaves at Rochester 

 and Geneva, N. Y., and Georgetown, D. C. At Rochester stem-moth- 

 ers, eggs, larvas, pupaj and alate adults were abundant. 



Phylloxera vastatrix Planchou. Galls on leaves of wild grape vines, 

 common at Portland, Mich.. Geneva and Georgetown. 



Chermes ahietis L. Abundant on Abies nigra in City Park, Al- 

 bany, July 29. None of the lice ready to leave the galls, though many 

 are pupge. The very pale yellow, almost white, color of larva^ and 

 the position of the galls, not terminal, are conditions quite in con- 

 trast with the rusty brown lice and the terminal position of the galls 

 in case of Chermes cooleyi. Galls also taken at Geneva.
