28 THE CANADIAN ENTOMOLOGIST. 



It therefore necessarily follows that the male of the plate, and its- 

 proper female, which is described, but not figured, is the true Angulosa, 

 S. & A., of which Georgica, H.-S., is a synonym, and that what we have 

 called Angulosa has never been properly described and named, but as 

 these moths have been so long known under these names, it is probably 

 best to allow them to stand as they are, as no injustice is thereby done, 

 and the female of the species now known as Angulosa was figured by 

 Smith and Abbot, though erroneously, under that name. 



THE SCIENTIFIC NAME OF THE CHERRY FRUIT-FLY. 



BY M. V. SLINGERLAND, CORNELL UNIVERSITY, ITHACA, N. Y. 



In September, 1899, I published an account of a new cherry pest, 

 which I called the cherry fruit-fly (Bulletin 172, Cornell Experiment 

 Station). As stated on pp. 31 and 7,2 of this bulletin, the identity of the 

 adult insect had not then been established, although the evidence strongly 

 indicated that it was the fly known as Rhagoletis cingulata, Loew. 1 

 kept my breeding cages containing the hibernating puparia of the insect 

 in the warm greenhouse or insectary all winter, and on March 9th, 1900, 

 the first cherry fruit-fly emerged. It did not disappoint my expectations, 

 for it demonstrated beyond further doubt that this new cherry-fruit pest is 

 Rhagoletis cingulata, Loew. By May 31st nine more of the flies had 

 emerged, and then cherries near the insectary were nearly half grown. 

 The flies continued to emerge until July nth in my cages, and on June 

 30th I received word from Geneva that they were abundant about 

 the trees where the fruit was ripening. This correspondent caught quite 

 a number of the flies with sticky fly-paper hung on a shingle in a tree ; he 

 said they seemed to be attracted to any bright-coloured thing like a new 

 straw hat. 



Since the Bulletin was written, I have received evidence to indicate 

 that the pest had been destructive during the preceding three to five 

 years at Bonaparte, Iowa; Westboro, Mass.; State College, Pa.; Batavia, 

 Syracuse, Portland, and Cataraugus, N. Y. Correspondents at West- 

 boro, Mass., and Clifton Springs, N. Y., think that the same insect worked 

 in their cherries at least thirty-five years ago. 



Considerable damage was done by the insect in New York in 1900, 

 but we heard little of it in 1901. 



Mailed January 10th, 1902.
