^* The list in this fartiily was originally prepared by Dr. E. P. Felt, and the manuscript has been 

 looked over by Dr. W. E. Britton. 



25 To the list of the Coccidae compiled by Dr. E. P. Felt several years ago, has been added, 

 through Harold Morrison, a summary of the numerous New York species, host, and distribution 

 records contained in the coccid note files of the Bureau of Entomology of the United States 

 Department of Agriculture. About fifty new species and many additional locality records 

 have been obtained from this source. The majority of these are based on determinations by Mr. 

 Morrison. No special attempt has been made to separate the statements made by each, nor is 

 either of these authorities to be held responsible for errors in the list. All dates are omitted, since 

 many specimens are collected long after their death.
