In 1890 we received it from F. A. Brown, Everett, Mass., and T. A. 

 Williams, Ashland, ISTebr., found on watermelons and cucumbers. 

 Specimens of the same species, found infesting leaves of orange, were 

 brought by Mr. A. Koebele from Adelaide, Australia. 



In June of 1891 it was again reported as being injurious to orange trees 

 by Dr. L. (Jr. Yates, Santa Barbara, Cal., while Mr. Edward Burrough, 

 of Merchantsville, N. J., stated that it had caused thousands of dollars' 

 worth of damage to melon vines in that section of the State. Keports 

 from J. B. de Vincenzi, Fort Bowie, Ariz., and F. S. Earle, of southern 

 Mississippi, were to the effect that considerable damage was done to 

 melon and cucumber vines. 



During 1892 it was reported as being injurious to oranges at Ham- 

 ilton, Bermuda, and Lakeside, Cal. ; to melons at Punta Gorda, Fla., and 

 Laredo, Tex.; to squashes at Lincoln, Nebr., and to cucumbers at 

 Dalcour, La. 



In 1893 it was injurious in Kansas and Oklahoma. 



In 1891 it was brought by Mr. H. G. Hubbard from Montserrat, 

 British West Indies, found in considerable numbers on orange leaves. 

 Mr. E. A. Schwarz, while investigating cotton insects during the 

 month of August, reported it to be extremely abundant on melons at 

 Rockport, Tex., and in lesser numbers on cotton at Baton Eouge, La. 

 It was also reported as doing some damage to melons at San Diego, Cal. 

 During September it was reported by Prof. C. H. T. Townsend as being 

 quite plentiful on cotton at Zaragoza, San Juan de Allende, and Mat- 

 amoras, Mexico. 



FOOD PLANTS OF APHIS GOSSYPII. 



During the past season an effort has been made to ascertain the 

 various food-plants, besides the cucurbitacetie, upon which this species 

 may be able to subsist and to multiply, and we have succeeded in 

 tracing it to the following long list of plants, to which, in the course of 

 time, many others will, no doubt, be added : 



Purslaae ( Portidaca oleracea), in larj^er aud smaller colonies, from early in June 

 until the plants are killed by frost. On a leaf of one of these plants infested by 

 this aphidid a winter egg was found late in October. 



Shepherd's-purse {Capsella bitrsa-pasiorh), frequently in large colonies on flowers 

 and flower stalks; September to January or later; even after heavy frosts, sleet, and 

 snow. 



Pepper-grass (Lepidium rirgiiiiciim), in large numbers on flower-stalk in October. 



Amarantus sp? leaves, October. 



Dock {liumex crispits and other species), October. 



Burdock {Lappa, major), small numbers, early in December. 



Dandelion {Taraxacum dens-leonis), quite numerous in October. 



Pigweed {Chenopodiam album), often plentiful on flower-stalks and leaves, October 

 and later. 



Wormseed {Chenopodium anthelmiuthirum), October, in small numbers. 



Plantain (Plantago virginica), in numbers on leaves from October until December. 



Chickweed (Stellaria media), in considerable numbers, October.
