A common Tingid that infests hazlenut, Corylus americana 

 Walt. We have specimens that were taken by Mr. W. L. 

 McAtee "near Plummers Island, Maryland, August 20, 1914." 



Corythucha floridana Heidemann. 



Our specimens are from Kissimmee, Florida, where they 

 were reported by Dr. Berger as doing a considerable amount of 

 damage to the oak trees. Heidemann reports the species as 

 being found on Cephalanthus. 



Corythucha gossypi Fabricius. 



Our Florida specimens were taken on the leaves of Icthyo- 

 nethia piscipula. We also have a few specimens from Grenada, 

 British West Indies. 



Corythucha pergandei Heidemann. 



This is a very common species that infests Alder. We have 

 specimens from Wisconsin, Illinois, Ohio, New Jersey, Wash- 

 ington, D. C, Maryland and Tennessee. 



Corythucha crataegi Morrill (Osborn and Drake). 



The hawthorn Tingid is common throughout the greater

 Dakota, Nebraska, Iowa, Wisconsin, Ohio, Pennsylvania, 

 Massachusetts, Maryland, Virginia, South Carolina, Georgia, 

 Texas and Colorado. Some w^orkers have questioned the 

 priority of the name, claiming that the species is identical with 

 C. cydonia Fitch. According to the International Code the 

 original description of cydonia is invalid, as it was not published 

 in a scientific journal. We would be glad to recognize cydonia 

 if the identity of the two forms can be fully established. 



Corythucha pallida Osborn and Drake. 



This species was described from a series of specimens that 

 were taken on linden, Tilia americana, by Kellicott and Hine. 

 During the past summer we have received numerous specimens 

 that were taken on mulberry. Morns rubra, in Ohio, Maryland,
