TWO SEASON'S COLLECTING OF APHID^, PRINCIPALLY 



ON LONG ISLAND, NEW YORK, WITH NOTES ON 



SOME OF THE SPECIES. 



By Chris E. Olsen, West Nyack, N. Y. 



The Alphidse listed below were all collected by the writer and 

 represent two seasons' attention to this group. The material was 

 gathered with the intention of building up a study collection but, 

 after making an earnest effort it was abandoned, through lack of 

 time to prepare material, for other groups in the Homoptera re- 

 quiring less time to prepare. One that has tried to work on this 

 family can well appreciate what others have accomplished. 

 These few words may be considered a modest apology for print- 

 ing a mere list with so few comments. 



The writer is much indebted to Miss Edith M. Patch of the 

 Maine Agricultural Experiment Station, Orono, Maine, and to 

 Mr. John June Davis, then at the United States Entomological 

 Laboratory, West La Fayette, Indiana, and wishes here to express 

 his appreciation for their willing and unfailing assistance in de- 

 termining the material, as well as to Mr. Norman Taylor of the 

 Brooklyn Botanical Garden for his kind determination of the 

 food plants. Credit must be given to Miss Dorothy Olsen for 

 the tedious work of copying the labels and compiling the list. 



With few exceptions, the slides have all been deposited with 

 the American Museum of Natural History. The comments on 

 the food habits are based largely on the recent work by Wilson 

 and Viccory, Trans. Wis. Acad. Sci. Arts and Letters, Vol. 

 XIX, Pt. I, pp. 22-355, 1918. The asterisk (*) indicates new 

 specifically determined food plants. 



Macrosiphum taraxaci Kaltenbach. 



Maspeth, N. Y., VI, 27, 1914, on Taraxacum officinale. 



There seems to be very little in American literature concerning 

 this dandelion aphid. I have seen no record of its being taken in 

 New York State. 



Macrosiphum pisi Kaltenbach. 



Wading River, N. Y., V, 30, 191 3, on Medicago lupulina*
