NOTES ON THE EXTERNAL CHARACTERS OF THE SAN JOSE SCALE, CHERRY SCALE, AND PUTNAM'S SCALE

Abstract

March 14th, 1898.—During the last two or three weeks, I have received inquiries from Georgia, Iowa, Kansas, and Canada, regarding the structural external character of the San José scale (Aspidiotus perniciosus), Cherry scale (A. Forbesi), and Putnam's scale (A. ancylus). I present, therefore, a few notes on these species, which I hope may be of some use to my fellow workers.
