Apterous Summer Vivipara. Dull black with dusky bands; with slight pulverulence; 
appendages dark. Body length 2, width 1.25; hind tibia .60-.80; antenna .65-.80; rostrum at- 
taining 3d coxa. Hairs on body simple or occasionally flattened to capitate at tip, .05-.06 
long; on hind tibia simple, about same length as diameter of tibia. A circular structure 
resembling cornicle opening appears on lateral portion of all abdominal segments except V, 
Vi and VIII. 
Alate Vivipara. Same size as aptera or slightly larger in all parts. Secondary sensoria 
protruding, oval; unguis slender and fingerlike. Hairs on hind tibia about as long as diameter 
of tibia. Rostrum rather broad, barely attaining 3d coxa. 
Ovipara. Mounted specimens appear similar in color to apterous vivipara. Body length 
1.8, width .90-1; antenna .45-.57; hind tibia .40-.50, not swollen and without evident sensoria, 
but two eggs Visible 3 in the bodies of partially cleared specimens. 
Collections. On Hordeum sp., on roots. Colorado: Fort Collins and Chero- 
kee Park. Apterous summer viviparae Sept. 6 to 24, alate viviparae Sept. 13, 
oviparae Sept. 6, 16, and 24; rare. 
Type. U.S.N.M., No. 41950. Paratypes, Colo. Agr. Exp. Sta. Collection and

This species differs from A. querci as follows: Relative lengths and sen- 
soriation of the antennal segments (IV over half length of III, sensoria not 
uniform), more slender unguis, dark color of the aptera, lack of dorsal dark 
patch on fall alata and presence of ovipara on grass roots.
