Second — Regarding Monellia caryae (Mon.) Gill. This species does not 

 hilong to this genus, but was plrieed there by mistake — the only species belonging 

 to this genus being cari/clla I'iteii. 



Third — Megoura nolani is not a synonym of Myzus pcrsicae (Sulz.), but a 

 good and distinct species. 



Fourth — That I'emphigus ritifolinc Fitch should have priority of P. vastatrix 

 I'lanch., because it was so described twelve years before the latter. 



Fifth — That it has never been positively proven that Lachnus deniatus Le 

 Baron is a synonym of the P'uro])ean LacJnivs viiiiinalis Boyer. 



I believe that this information will be valuable to all workers of this group 

 and wish to state that if all would send criticisms and suggestions such as these 

 from Mr. Davis the work would soon be placed upon a more certain and definite 

 basis. It is my sincere wish that no mistake shall go without immediate correction 

 and always extend an invitation for corrections such as the above.
