Dr. Thomas, inrepeating these descriptions in the ‘A phididz” (Sth Re- 
port State Entomologist of Ilinois, pp. 141, 142), separates the two by 
Schizoneura carye Fitch, so that “ Differs from preceding only,” ete., re- 
fers to carye and not to fungicola. This circumstance is liable to mis- 
lead, unless Walsh’s original descriptions are at hand for reference, and 
may account for the uncertainties that have been stated in efforts to 
determine Walsh’s cornicola found on Cornus. 
Considering that fungicola was on a fungus, a plant never known to 
support Aphides, and that the difference noted by Walsh is such as 
results from greater maturity of specimens that have located on Cornus, 
and further, that fungicola agrees perfectly with both descriptions of 
corni and with fresh individuals found on Cornus leaves, it seems pretty 
certain that these two descriptions refer to one and the same species. 
Thomas’ description of S. panicola, published in 1879 (8th Report, 
State Entom., Illinois, p. 138), is as follows, and is said to have been 
written from recent alcoholic specimens : 
Winged female.—The front wings with the third discoidal veins once forked; third 
vein obsolete at base; first and second veins arising very near each other; stigma 
short, rounded behind; fourth vein nearly straight; costal bent outward to the base, 
leaving arather wide space between it and the subcostal; antenn short, reaching 
about to the base of the fore wing; slightly hairy; third joint rather longeythan the 
fourth and fifth united; sixth slightly longer than the fifth, with a very short, in- 
distinct, blunt spur at the tip; beak rather long, reaching nearly to the hind coxa, 
slightly hairy ; eyes present and of the usual size or nearly so. 
Wingless female.—(Probably not fully developed.) Very broadly ovate and very 
convex, being suborbicular; antenne, reaching about to the end of the thorax, rather 
thick and heavy and not tapering to apical joints, if any difference rather thicker 
than the middle ones; third joint longest but not quite equal to the fourth and fifth 
united; fifth rather longer than the fourth, gibbous on one side at the tip; sixth 
nearly as long as the third; beak, long, reaching fully to the hind cox ; color of the 
alcoholic specimens, reddish-yellow ; eyes minute and black. 
Found on the roots of Panicum glabrum and other grasses by H. [Th.?] Pergande 
at St. Louis, Mo., in November. 
The difference in the length of the beak will certainly distinguish this from Tychea 
panici, even supposing the antennze in the latter to be undeveloped. 
Mr. O. W. Oestlund,in Synopsis of the Aphididee of Minnesota (Bull. 
No. 4, Geol. and Nat. Hist. Surv. of Minn.) describes both corni and 
panicola, and their identity could not be more strikingly indicated. 
S. cornt. 
Head and thorax black; abdomen reddish-black, with a large patch of velvety 
black covering all of the dorsum except three and some of the last segments. An- 
tenn reaching to the end of thorax; not annulated, hairy, with a single row of cir- 
cular sensoria on the under side, about six to the third joint, three to the fourth, two 
to the fifth, and one at the contraction of the sixth; III, 0.30™™; IV, 0.12™™; V, 0.10™™; 
VI, 0.15™™, with the short unguis. Beak reaching third coxa. Wmtngs hyaline, with 
slender veins; cubital obsolete at base; stigma broad and short, smoky. Honey 
tubes a circular opening almost on a level with the abdomen. Expanse of wings, 
67mm, 
S. panicola. 
Head and thorax dusky or black; abdomen pale greenish with some black mark- 
ing above, on the last segment at least. Antenuz reaching to the end of the thorax,
