composed of a glutinous matter, which becomes 

 very hard when exposed to the air ; the case is 

 attached to a slender twig of the plant on which 

 the larva feeds ; in this case the larva remains 

 unchanged during the months of autumn, winter, 

 and spring. Imago with antennae seven-jointed, 

 of which the third joint is always elongate, and 

 the apical ones always form a club ; the mandibles 

 are longer than in the preceding order, acute at 

 the apex, and internally bidentate ; maxillae, with 

 the lacinia, obtuse and hirsute, the galea rather 

 obtuse and distinctly articulate, and the feelers 

 long arid six-jointed; labium short, with the 

 ligula distinctly trilobed, the feelers four-jointed ; 

 ocelli three ; segments of the body fully developed ; 

 oviduct as in the Allantites. Inhabits flowers 

 and leaves ; flies in the sunshine. Abia, Zarcea^ 

 Cimbex, Trichiosoma, Clavellaria. 



734. Lydites (Lydites). Larva smooth, cylin- 

 drical, with six short, articulate, and no prehensile 

 legs. Feeds on the leaves of trees, inhabiting a 

 web of its own making. Pupa changes in a silken 

 cocoon on the stem of the trees it inhabits, or on 

 the ground. Imago with the antennae composed 

 of seventeen to thirty joints, filiform, and atte- 

 nuated exteriorly ; mandibles long, acute at the 

 apex, and having one tooth internally ; max- 

 illae, with the blade and galea, obtuse, the feeler 

 long and six-jointed ; labium short, ligula more 

 produced, trilobed ; ocelli three ; head large,
