Extract

An apparently undescribed Amphorophora was received from Richard Stace-Smith of the Canada Agriculture Plant Pathology Laboratory, Vancouver, B.C., Canada. This species produced leaf symptoms on Munger black raspberry, Rubus occidentalis, which differed from anything associated with the feeding of Amphorophora rubi (Kaltenbach). An examination was made of the material by Professor M. A. Palmer, Dr. F. C. Hottes and the writer. This failed to place this blackberry aphid as a described species. Therefore, it is here described as new.
