of the antenna ; t, the mandibular appendage; o, the eye ; 4 b, one of the 
mandibles, with its appendage ; 4 c, ditto, seen laterally ; 4 d, the mandible 
detached from 4 e, the appendage ; 4 f, the latter seen laterally ; 4 g, the

nulatus (quadriarticulatus) conspicitur.” The part here described 
as the palpus is certainly identical with the appendage above de-
