The transition zone is flat in P. idas ( Fig. 22 C) with the cells formed by radially arranged pits, while in P. a rgu s ( Fig. 22 A) it consists on a undulating plateau with more quadrangular cells. The tubercle-aeropyle zone is arranged into hexagons, with robust walls and cone shaped and ribbed tubercles, which open into aeropyles at their tips. The equatorial zone has the widest cells, with robust walls and conical shaped tubercles.
