IDIOCERUS SCURRA GERMAR, A POPLAR 

 LEAFHOPPER. 



By Edgar L. Dickerson and Harry B. Weiss,* 

 New Brunswick, N. J.

 1916 when Lombardy poplars in a nursery at Irvington, N. J., were 

 found to be badly infested by nymphs and adults. During the sum- 

 mer of 1917 an opportunity was presented to study this insect. When 

 our work was almost completed, it was brought to our notice by 

 Mr. E. P. Van Duzee that Idiocerus g enimisimulans L. & C, was a 

 synonym of scurra Germ., and Mr. W. H. Brittain, who has examined 

 the types of /. gemmisimulaiis at Cornell, came to the same conclu- 

 sion. Idiocerus gemmisimulaiis was treated in part by Leonard and 

 Crosby in the Jour. Econ. Ent., Vol. 8, No. 6, p. 541, but in order to 

 add further to the knowledge of the species, the publication of this 

 paper was decided upon. 



Idiocerus scurra Germ, appears to be well distributed in New 

 Jersey in spite of the fact that it does not appear in Smith's " List of 

 the Insects of New Jersey." It has been found in New Jersey on 

 both Lombardy (Populus nigra italica) and Carolina poplars (Popultis
