widely separated points as Illinois, Iowa, Ontario, Washington, D. C, 
California, and Tennessee appear all within five years of its first 
notice. 
In this connection the unpublished records of the Illinois State 
entomologist, which were kindly placed at my disposal by Prof. 
Forbes, are of special interest. These records show the species to 
have been taken from wheat, oats, or grains, etc., in Illinois at the 
following places: Carmi, October 6, 1882; Cuba, May 15, 1883; 
Decatur, May 23, 1883 ; Bloomington, May 24, 1883; Normal, May 28, 
1883; "S. 111.," August, 1883; Centralia, August 7, 1883; Cherry 
Valley, August 17, 1883; and at West Union, Mt. Carmel and Marshall 
in May, 1884. This would show the species to be distributed over 
the entire State and to be well established, as in many cases the speci- 
mens in the collection are in large numbers and indicate an abundance 
in the field. The published record, moreover, speaks of them as in 
destructive numbers. 
I took it in great numbers in Washington, D. C, in July, 1890, 1 
and it appears in my list of Iowa species of Jassidse in 1892. 
In the Hemiptera of Colorado (1895) the species is recorded from 
Colorado Springs, August 1, and Fort Collins, July 24. 
The National Museum shows a single specimen labelled "C. Mo. 
June" without date, evidently from the old Riley collection and prob- 
ably collected before 1880; specimens from Los Angeles County, 
Cal., collected by D. W. Coquillett, which must have been taken between 
the years 1886 and 1893; others by Koebele, Sacramento and Placer 
Counties, Cal., certainly since 1880; one from San Francisco, Cal., 
June 24, 1885; one from Massachusetts, no date, but evidently a 
recent specimen, and another from Cimarron, Kans., 1891. 
Bureau records or specimens show it to have been taken within the 
last five years at Clemson College and Spartanburg, S. C. ; Hamilton, 
Ala.; Dallas and Denison, Tex.; Mansfield, Ark.; Mesilla Park and 
Springer, N. Mex. ; Wellington and Manhattan, Kans.; Kingfisher, 
Okla. ; and Tower City, N. Dak. 
In March, 1909, Mr. Harper Dean reported as follows: 
Denison, Tex., March 22, 1909, drove 4 miles from town to farm of Mrs. Delia 
Cramer, whose small field of barley, about one-fifth acre, had been Hlled outright, a 
week or ten days previously, supposedly by Toxoptera. No sign of the latter could 
be found, but there was an abundance of Jassidse, all of one species. She said these 
were the prevalent insects at the time of the outbreak. Took a number of specimens 
and determined them by Dallas collection as Cicadula 6-notata Fall. Gave Mr. Tucker 
some of these specimens, brought remainder to San Antonio. The latter were so 
mutilated en route that only a single specimen was good. Sent this to Prof. Webster. 
I found it generally distributed for the season of 1909, northwest 
to Washington State and southeast to South Carolina and Georgia.
