Doran, forms Bulletin No. 16 of the Maryland Station. 
Dr. J. B. Smith continues his contributions to a monograph of the

Entomology at Rochester.—The Rochester meeting of the 
A. A. A. S. was one of unusual interest to entomologists, both from 
the number present and the interest shown in the papers presented. 
Most of the entomological papers were presented before the Associa- 
tion of Economic Entomologists and the Entomological Club, while a 
few of especial interest were presented before the Society for the Pro- 
motion of Agricultural Science and Section F of the general Associa- 
tion. ,
