Chief Distinguishing Characters. Small size (not larger than 1.5), rather 
short bushy cauda (5-6 pairs of hairs), shape of the cornicle (usually narrowed 
in middle), and six-segmented antenna. The latter character distinguishes this 
species from A. rubifolii.

length 1.2; hind tibia .45-.50; antenna, III and IV coalesced, .50-.60; III and IV not perfectly 
coalesced, .90; rostrum attaining between 2d and 3d coxae. Hairs pointed. Cornicle cylin- 
drical or slightly tapering, with flange and imbricated. Cauda short, parallel-sided, bluntly 
rounded, sometimes silghtly constricted, bearing 3-4 pairs of lateral hairs and 2 mediodorsal

Collins, Cherokee Park and Poudre Canyon. Utah: Clearfield, Eden, Ogden, 
Farmington, Layton and Logan. Idaho: Twin Falls. Apterous viviparae June 
4 to Oct. 25, oviparae Sept. 24 to Nov. 2, m»les Nov. 2; apparently rare. 
Neotypes. Ill. Nat. Hist. Surv. Collection, No. 4425. 
Chief Distinguishing Characters. Small size, pale yellowish body, short 
bushy cauda, few sensoria on III of alate vivipara (not more than 7), character 
of hind tibia of ovipara (slightly swollen and bearing scattered, rather large, 
sensoria) and five-segmented antenna. The latter character separates this form 
from A. rubicola.
