Since these observations were made iu 1882 it appears that no one 

 has met with it again until Professor Weed's attention was called to it 

 by Mr. S. R. Kramer, of Gahanna, Franklin County, Ohio, who submit- 

 ted specimens during the latter part of August, 1889, which he found 

 to infest the roots of his strawberry plants, with the report tliat he tirst 

 noticed them to be very abundant upon his plants about the middle of 

 July, since which tune they had ruined a plantation some two and a 

 half a',-res in extent. An investigation by Mr. Weed of the plants upon 

 the station grounds atOolnmbus, Ohio, showed that a large proportion 

 of them were also infested by the same insect. He ascertained also 

 that it was quite generally distributed over the State. 



Prof. J. B. Smith, in an article on the melon aphis published in Bul- 

 letin 72 of the New Jersey Agricultural Experiment Station (October 

 4, 1890, pj). 24-20), makes the statement that this species has been very 

 destructive to all kinds of cucurbitaceous vines for years, and that 

 numerous complaints of injury had been received m the fall of 1889 

 from farmers in all i)arts of the state. 



The notes of this office regarding distribution of, and damage caused 

 by, this species date back as far as July, 1878, when it was reported as 

 being very numerous on the leaves of orange trees at Fort Reed, Fla. 



During March, 1879, it was again reported as being very numer- 

 ous on orange trees at Savannah, Ga., while iu May of the same year 

 complaints were received from Selnia, Ala., where it appeared in large 

 numbers on the leaves of cotton. 



Early in the spring of 18S0 it was found by Mr. A. Koebele also on 

 cottou, at Bonito, province of Pernambuco, Brazil; while in April of 

 the same year it was reported by 11. S. Williams, Rockledge, Fla., as 

 doing some damage to the leaves of orange, Tiie same species was 

 sent us in June by W. F. Morgan, Palmyra, K. J., with the statement 

 that it^vas very destructive to citron vines, a variety of watermelon, the 

 underside of the leaves of Avhich were completely covered with them. 

 In July we received it from J. E. Pierson, Fremont, N. C, with the 

 statement that it was doing some damage to cotton. 



During 1881 no complaints were received, except from Mr. J. R. Mar- 

 tin, Clarksville, Tenn., that his cucumbers, melons, and cantaloupes 

 were badly infested with it during September. 



From 1881 to 1888 it seems to have done little or no damage any- 

 where; since then, however, it has beeu received regularly every year 

 from different sections of the country. 



During 1888 it was reported iu June by M. G. Acton, Sarasota, Fla., 

 as doing considerable damage to his melon vines; it was also received 

 in September from J. A, Shuler, Bonifacio, Fla., and from R. H. Whit- 

 tacker, Gardner, Kans., with the statement that much damage was 

 done ou melon and cucumber vines. 



In 1889 it was found infesting leaves of oranges at Los Angeles, Gal., 

 by Mr. D. W. Coquillett.
