In generalappearance and structure it is like a deometrid pupa,resembling one also in its markings, having longitu-dinal stripes. In Tantura (fig. 44) the shape of thealxlomen is moie generalized, there being no cremaster, but hooked seta^ enabling it to retain itshold witliin its beautiful loose basket-like cocoon. It is probable that these genera descended from some broad-winged Tineina, and possiblyfrom the Prodoxida;; Hyponomeuta, and especially Argyresthia, appear to be later, more .specializedforms.
