pupa nearly as in the Chri/somelites, Imago with 

 long filiform antenna-, inserted much nearer to 

 each other than in either of the two preceding 

 orders ; mandibles acute ; maxillae obtuse, with a 

 distinctly articulate palpiforni galea ; legs of similar 

 structure, not formed for leaping ; form more 

 elongate. Inhabits and feeds on vegetables ; 

 flies more readily than the two preceding orders, 

 but does not leap. Galeruca, Aditnonia, Auchenia, 

 Lwperus, 



778. Criocerites {Criocerites). Larva more 

 linear and elongate. Feeds on the leaves or 

 within the stems of vegetables. Pupa generally 

 changes in a silken cocoon, attached to the stems 

 or roots of the vegetables on which it feeds. 

 Imago with moniliform antennae, slightly incras- 

 sated externally, about as long as in the Gale- 

 rucites ; mandibles arcuate, bifid at the apex ; 

 maxillae obtuse ; galea incrassated, but not palpi- 

 form ; prothorax proportionately much smaller 

 than in any other order of the stirps : somewhat 

 cylindrical ; tarsi four-jointed ; colours brilliant ; 

 flight only occasional, diurnal. Inhabits vegetables. 

 Crioeeris, Donacia. 



779. Necked capricorn-beetles (Lepturiies). 

 Larva almost entirely without feet, fleshy, 

 linear ; inhabits decaying timber. Pupa changes 

 in the same situations. Imago with filiform an- 

 tennae usually about the length of the body, 

 inserted between the eyes, but not interfering
