A NOTE ON CERTAIN PSYLLIDAE 



D. L. CRAWFORD 

 STANFORD UNIVERSITY, CALIFORNIA 



By an unavoidable delay in the publication of a more extensive paper on 

 the Psyllidae, the manuscript of which has for some time been in the hands of 

 the publishers, the description of the new genus Psyllopa, and of Psylla americana 

 have not yet appeared. Reference was made to both of these names in my last 

 pa])er on American Psyllidae V, in this Journal, pages 628-32. These descriptions 

 will be published very soon. 



On page 629 of the above mentioned article, the name Psyllopa fioridensis 

 should be replaced bj- Psyllopa ilicis Aslimead, and the note on jiage 6.S2 relating 

 to this species should follow the description.
