No. 34.] HEMIPTERA OF CONNECTICUT: CICADELLIDAE. 161 



Only a few of the varieties occur in vineyards and these in very 

 small proportions. Such forms as ziczac are more abundant on 

 woodbine and other vines and are seldom found on grapes. So 

 from field observations it is doubtful whether some of these should 

 have varietal or specific ranking.
