 rather common butterfly in southeastern Nebraska, and the hack-berry 

 trees are scarce, it is evident that its chief source of food in this region 

 is found in the more common wolf-berry. — H. G. Barber, University of

Entomological Literature. 



[The Associate Editor, contemplating an extended absence from Phila- 

 delphia, offered his resignation to the chairman of the Publication Com- 

 mittee of the News. While this has not been accepted, his editorial 

 connection for the present will be nominal only, and beginning with the 

 next (September) number the Entomological Literature will be under the 

 charge of Mr. William J. Fox. It may be well to add that the Associate 

 Editor has exercised his editorial functions, during the past five years, 

 only in preparing the monthly summaries of the entomological literature 

 and the annual indices to the volume. — P. P. C]
