258 CLASSIFICATION OF INSECTS. 



Aphites which suck their sap. Pupa attaches itself by the 

 tail to a leaf, and changes in that position. Imago with 

 short and rather clavate antenn<B ; mandibles acute ; tarsi 

 three-jointed; form very convex above, nearly hemispheri- 

 cal. Inhabits vegetables, feeding on the Aphites which 

 infest them. Cacicula, Chilochorus, Coccinella. 



Bloody-nose beetles or Chrysomelites. Larva still more 

 obese, inactive ; legs short. Feeds on the leaves of vege- 

 tables. Pwpa sometimes attaches itself, and changes in 

 the same situations, and sometimes in the earth. Imago 

 with moniliform antennce, inserted far from each other ; 

 mandibles rather obtuse ; maxillee obtuse ; galea palpiform, 

 exarticulate ; head nearly concealed by the prothorax ; 

 tarsi four-jointed ; legs not formed for leaping; form very 

 globose, inactive ; flies seldom. Inhabits vegetables, on 

 the leaves of which it feeds. When touched frequently 

 emits a red fluid from the mouth. Cryptocephalus, Clythra, 

 Chrysomela. 



Flea-beetles or Alticites. Larva and pupa nearly as in 

 the preceding order, the former rather less obese. Imago 

 with the antennae much longer, more filiform, and inserted 

 nearer together ; mandibles more acute ; maxillae obtuse ; 

 galea palpiform and articulate ; hind legs incrassated, 

 formed for leaping ; form less globose. Inhabits and feeds 

 on vegetables ; its size is little larger than that of a flea, 

 an insect which it emulates in the activity of its leaps ; it 

 is excessively injurious to crops, sometimes causing a total 

 failure of turnips, rape, &c. Altica. 



Galeriicites. Larva and pupa nearly as in the Chryso- 

 melites. Imago with long filiform antennae, inserted much 

 nearer to each other than in either of the two preceding 

 orders ; mandibles acute ; maxilloB obtuse, with a distinctly 

 articulate palpiform galea ; legs of similar structure, not 

 formed for leaping ; form more elongate. Inhabits and
