260 CLASSIFICATION OF INSECTS. 



not dilated as in the preceding order, which in many of 

 its characters it very closely resembles. Inhabits vegeta- 

 bles, on which it feeds. A single species, Hispa atra, is 

 said to have been found in England. The author is in- 

 duced, from the observations of Dr. Harris on the economy 

 and structure of the larva and pupa of Hispa, to separate 

 it from the Cassidites, a family of which he had previously 

 considered it. 



Criocerites. Larva more linear and elongate. Feeds on 

 the leaves or within the stems of vegetables. Pupa gene- 

 rally changes in a silken cocoon, attached to the stems or 

 roots of the vegetables on which it feeds. Imago with 

 moniliform antennae, slightly incrassated externally, about 

 as long as in the Galerucites ; mandibles arcuate, bifid at 

 the apex ; maxilla obtuse; galea incrassated, but not pal- 

 piform ; prothorax proportionately much smaller than in 

 any cognate order, somewhat cylindrical; tarsi four jointed; 

 colours brilliant ; flight only occasional, diurnal. Inhabits 

 vegetables. Crioceris, Donacia, Macroplea. 



Necked capricorn-beetles or Lepturites. Larva almost 

 entirely without feet, fleshy, linear ; inhabits decaying 

 timber. Pupa changes in the same situations. Imago 

 with filiform antennae usually about the length of the body, 

 inserted between the eyes, but not interfering with their 

 form ; the head is elongated at its junction with the pro- 

 thorax, somewhat in the manner of a neck ; mandibles 

 terminated generally in an acute point ; maxillae obtuse ; 

 galea obtuse, not palpiforrn ; form elongate, attenuated pos- 

 teriorly; tarsi four-jointed; diurnal. Inhabits flowers, ap- 

 parently feeding on their pollen. Leplura, Pachyta. 



Neckless capricorn-beetles or Cerambycites. Larva and 

 pupa as in the preceding order. Imago with filiform an- 

 tennae, often much longer than the body, inserted close to 

 the eyes, and partly surrounded by them ; the eyes conse-
