During 100.") this species l)ecanie unusually abundant in the Dis- 

 trict of Columbia and in localities in adjacent States. Specimens 

 of mined apple lea.ves were received from Afton, Va., Newark and 

 "Woodside, Del., Cheltenham, Pa., and Vermont. Judging from the 

 condition of the leaves sent, the insect in these several places was 

 much less abundant, however, than in the immediate vicinity of 

 Washington. During 190G the insect Avas again exceedingly abun- 

 dant in the environs of Washington, was the subject of further com- 

 plaint from DelaAvare. and was received from Connecticut. 



HISTORY. 



This species was described in 18G0 l)v Clemens in the Proceedings 

 of the Philadelphia Academy of Sciences. Volume XII. page 208. 

 from material presumably from Pennsylvania. Interesting observa- 

 tions concerning its food plants are presented by Chambers in thf 

 Canadian Entomologist. Volume III (1871). page 208; Volume V 

 (1873), page ."SO. and Volume VI (1874). page 150. Additional note- 

 are given by him in the Cincinnati Quarterly Journal of Science. 

 Volume II (187.5). page 3; in Bulletin U. S. Geological and Geo-
