Tlie immature examples of this insect are as handsome as the adults, but very different in color and color pattern (see plate IV, fig. 17). These arc solidly black dorsad with a very narrow mediolongitudinal buffy line and the lateral margins more broadly of the same coloration. The antennae are black, with a broad medioproximal and broader medio-distal annulus of white. The cerci are black, fading proximad and distad to buffy.
When we consider that the very complex color pattern of the adult appears only after the last moult, it is surprising to find it as extremely constant as is shown by this and other considerable series of the species at hand.
In the adult condition the maxillary palpi arc always whitish, never showing darker markings or suffusions.
