Except when greatly engorged, the peripheral flange of the 

 body remains partly iinfilled. In partially engorged individuals 

 this flange is fJ.at, and in dry specimens it may be tixrned up 

 like a rim. The body color is reddish yellow with a central, 

 darker area of varying extent. 



Males measure from 5»9 mm, to 6, A mm, long, and from 7,U ram, 

 to 7.8 mm, wide (average 6,1 mm, long and 7,5 mii, wide). The 

 genital aperture forms a wide arc. Females are larger, and measure 

 up to 8,0 mm, long and 9.5 mm, wide. The female genital aperture 

 is a transverse groove with thick, rugose lips. 



The nymph and larva have been described by Hoogstraal (1955B), 

 The larva and first instar nymph are quite similar to those of A, 

 boueti but the successive instars of each resemble the associated 

 adults.
