distinctions which have some desirable features to transfer Beri/tidce to the end of 

 the Coreoidea bringing the sub family RhopaUna next to Pseudophlwina. 



The previous list includes Cymodema tahida vrhich should probably be omitted 

 from the list entirely. The name was inserted in a preceding list from specimens 

 from an excellent authority on Hemiptera, who has, however, since stated the de- 

 terminations were incon-ectly given to hina, the species so named being Cj/tnus 

 claviculus, and I find my specimens to agree with European specimens of this 

 species. I am unable at present, however, to find any Iowa specimens of this 

 species and fear that the former record was inadvertently made from other speci- 

 mens. 



Gypona flavilineata. Fitch. After a careful comparison of a large number of 

 specimens of this form with Fitch's descriptions and with typical octolineata I am 

 satisfied that it is a distinct form. 



The entry of Acocephalus sp. was made from an early generic determination 

 from Mr. Van Duzee who has since described the species as Anthysanus comma. 

 and the species should so stand. 



Grypot'es unicolor, Fitch, is now made the type of Van Duzee's new genus 

 Chlorotettix. 



Chlorotettix tergatiis, Fitch. This is a rather common species, having somewhat 

 similar form and habits as unicolor, but of a tawny color 



Phlepsins strohi. Fitch. This is a common species, and occurs commonly on 

 the undersurface of the leaves of Pigweed, (Chenopodhim) causing them to turn 

 purple in spots. Its name — strohi — could hardly have been given with reference 

 to its food habits, as it appears here to be quite constantly confined to Pigweed in 

 larval stages and pretty generally, also, in the adult form. 



Paramesus twininqii, Uhl., is the form entered in precedmg list as Paramesus, 

 sp. Mr. Van Duzee having reached this conclusion after careful comparison with 

 the type of the species. 



Telamona accllvata andfaffi should be referred to the genus Heliria, Stal. 



Enchenopa curvata is now included in Campylenchia, Stal. 



Pachypsylla c-minuta Riley, is entered m previous list as Pacliypsylla sp. 



Pachypsylla c asterisciis, Riley, is another form occurring on the Hackberry. 



In another paper will be found additions to the list of Aphididte. 



I am indebted to Mr. E. P. Van Duzee for a number of these corrections.
