162 THE CANADIAN ENTOMOLOGIST. 



The moth proved to be the one described by Grote and Robhison in 1868 

 as purpurifascia. Imagine the Hght spots in the figure to be of a 

 delicate creamy white colour, the other shades as various shades of orange, 

 purple, and russet brown, and you will have a faint conception of the 

 rather uncommon but beautiful combination of colours presented on the 

 wings of this insect. 



I can find no reference in the literature to the early stages or habits 

 of this insect. On account of its destructive work in Mrs. Glessner's 

 columbines, it may be appropriately called " the Columbine borer." The 

 moth has been recorded as occurring in Maine and Massachusetts in 

 September and October,- and in New York in August ; it is also known to 

 occur in Illinois and Colorado. Mrs. Glessner writes that she has found 

 that rich soil, cultivation, and Fowler's solution of arsenic (diluted one- 

 half with water) poured around affected plants seemed to check and control 



the pest.

THE RASPBERRY-CANE MAGGOT' 

 (Phorbia rubivora, Coquillett). 



by m. v. slingerland, cornell university, ithaca, n. y. 



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 illus- 

 trated in the Bulletin. At the lime the Bulletin was written, however, the 

 name of the insect had not been determined. In April, 1897, ^ 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. 



Phorbia rubivora, Coquillett, n. sp. — $. Ground colour black; 

 sides of front and of face white poUinose, eyes sub-contiguous, more 

 approximated to each other than are th^ two posterior ocelli, frontal vitta 

 at the narrowest part linear ; third antennal joint less than twice as long 

 as broad, slightly over twice as long as the second, arista thickened on 

 the basal third, the penultimate joint slightly longer than broad. Thorax 

 grayish poUinose, marked with three black vittae ; three postsutural and 

 three sterno-pleural macrochaette. Abdomen quite thickly covered with 

 suberect bristly hairs ; narrow, subcylindrical, greenish-gray poUinose,
