THE CAiNAiDIAN ENTOMOLOGIST 95 



I repeat that the instances which I have cited above are simply a few of 

 the examples to be found in the treatment of the Diaspinae. An extended 

 analysis will show many others equally worthy of criticism. I can not believe 

 that such work as this can do anything more than extend the confusion already 

 existing in the group. 



THE ACADIAN ENTOMOLOGICAL SOCIETY. 



It will be of interest to many of the readers of the "Canadian Entomo- 

 logist" to learn that at the last meeting of the Entomological Society of Nova 

 Scotia, held recently in Halifax, it was decided to broaden out this Society 

 into a Maritime one to include the three provinces, Nova Scotia, New Bruns- 

 wick and Prince Edward Island. 



The name of the Society was also changed from the Entomological 

 Society of Nova Scotia to the Acadian Entomological Society, this name being 

 chosen on account of the fact that the territory embraced by the new Society 

 includes practically the same area as did the ancient Acadia. 



The Entomological Society of Nova Scotia has been steadily increasing 

 in numbers and influence since its organization in l^US, and it is felt that this 

 change is another decided step in advance. 



NOTE ON THE ROSY APHIS. 



BY A. C. BAKKR, 

 Bureau of Entomology, Washington, D.C. 



In 1916 \V. F. Turner and the writer published some results of a study 

 of the rosy apple aphis. We found that the insect was quite distinct from 

 A. sorbi Kalt. of Europe, and, following the lead of Mr. Pergande, we used 

 malifoliae Fitch for the species. At the time we had access to only a few of 

 Mr. Pergande's notes and were unaware that he had made studies on sorbi 

 in Gerinany. These studies convinced him that .wrbi and the rosy aphis are 

 distinct. Theobald reached the same "conclusion in England and Gillette from 

 Russian material was equally convinced. All who studied actual material agree, 

 therefore, that two forms are concerned. 



At the time we wrote our paper the Fitch type of malifoliae was thought 

 to be lost but this has since been located in a group of slides presented to the 

 National Museum by Miss Pergande. This material still bears the original 

 Fitch note book numbers. The species, however, is cratacgifoliae Fitch, the 

 type of which is also in the National Museum collection. The rosy aphis, 

 therefore, is again without a name, as the former names given it all refer to 

 different insects. We herewith give the species the name Anurapiiis roseus. 

 A full discussion of the synonymy will be given in a paper on the genus Anuraphis 

 which will soon be ready for the press.
