tapering, bearing 4 pairs of lateral hairs and one dorsal preapical one.

and measurements as in apterous summer vivipara except as follows: Rostrum barely attain- 
ing 2d coxa and hairs on vertex .02. 
Ovipara. Apterous. Dusky markings and measurements about as in summer apterous 
vivipara except as follows: Cornicle .50, cauda .10 on median line and hind tibia about 1.40, 
slightly swollen on proximal third which portion is rather thickly covered with sensoria.

30 to Oct. 11, alate males Sept. 12 to Oct. 15, oviparae Oct. 15; common. 
Type. Davis Collection. 
Chief Distinguishing Characters. Feebly swollen cornicle, about same width 
as hind tibia; absence of dorsal patch on abdomen in alate vivipara, cornicle 
with flange not oblique and absence of sensoria on IV and V. 
This species somewhat resembles A. sonchi but is distinguished by longer 
hairs and cornicle and absence of sensoria on IV and V in alate vivipara.
