ERRATA AND AUTHOR vS' EMENDATIONS 



Pages 60-63, legends to figures 3-S, "phosphate" should read "phosphorus." 



Page 175, Imes 45-46, Mr. Ainslie informs the author that he has never succeeded in rearing Pyrausla 

 ainsliei to maturity on Nelumbo lutea as here stated. In the discussion of P. ainsliei it should be stated 

 that the old name P. obumbralalis Lederer may eventually prove to apply to this species. Without an 

 examination of the genitalia of Lederer's types in Europe, however, it can not be determined whether 

 his name applies to this species or to P. penitalis Grote, if to either. In the meantime it is safest to employ 

 a definite name to a definite concept.
