This new raspberry pest has been discussed in detail in Bulletin 126, issued in February, 1897, from the Cornell Agricultural Experiment Station. The life-history and habits of this Anthomyiian are fully illustrated in the Bulletin. At the time the Bulletin was written; however, the name of the insect had not been determined. In April, 1897, I reared several more of the flies and sent some to Mr. D. W. Coquillett at Washington. He soon reported that the insect was a new species of Phorbia, and sent me the following technical description of the fly, which he had drawn up from the specimens I sent him.
