Collections. Quercus (migrants, accidental). On Cornus stolonifera, on

this region only on Cornus stolonifera. Colorado: Fort Collins, Delta, Paonia, 
Palisade and Cherokee Park. Utah: Generally, especially in northern half of 
state. Fundatrices April 25, apterous summer viviparae not taken, alate vivi- 
parae Aug. 27 to Oct. 31, sexuparae Oct. 1 to 22; common. 
Cotypes. U.S.N.M. 
This species has not been recorded here on its summer host, the grasses. 
This fact would seem to throw suspicion on the validity of the two species of 
Anoecia, namely setariae and graminis taken from grasses, suggesting them as 
*Evidently meaning crossbands.
