AMERICAN SPECIES OF ITONIDIDiE. 



A reference to the above table shows a fairly uniform tribal and 

 subfamily representation in the known New England forms. A 

 detailed examination of the list will show that much of our knowl- 

 edge of Cincticornia and Caryomyia is due to the work of Miss 

 Clarke. Comparing the New England fauna with that of the 

 western part of the Continent, it will be noted that in the latter, 

 both the Lestremiinariae and the Campylomyzariae exceed the New 

 England forms by considerable, while no representative of the 

 Heteropezinse has been collected and there is a relatively small 

 representation of the Itonidinaria?. Over half of the known Ameri- 

 can species have been reared. There is still an immense amount 

 of work to be done along this line and in New England at least, 

 one would expect judicious collecting to result in the discovery 

 of at least a fairly rich fauna in both the Heteropezinse and the 

 Epidosariae. 



A considerable porportion of the many forms occurring on Salix 

 and Solidago 3 should be found in New England. 



In addition to the species tabulated below, there are some 

 twenty-two names which have been applied to galls collected in 

 New England and which probably represent undescribed forms. 

 These latter names, some of which are valid, are given at the end 

 of the list.
