of a tortoise ; tarsi four-jointed ; form nearly 

 hemispherical. Inhabits vegetables, on which it 

 feeds. Cassida. 



775. Bloody -nose beetles (Chrysomelites). Larva 

 still more obese, inactive ; legs short. Feeds on 

 the leaves of vegetables. Pupa sometimes attaches 

 itself, and changes in the same situations, and 

 sometimes in the earth. Imago with moniliform 

 antennae, inserted far from each other ; mandibles 

 rather obtuse ; maxillae obtuse ; galea palpiform, 

 exarticulate ; head nearly concealed by the pro- 

 thorax ; 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, Chry- 

 somela. 



776. Flea-beetles (Alticites). Larva and pupa 

 nearly as in the preceding order; the former 

 rather less obese. Imago with much longer and 

 more filiform antennae, and inserted nearer together ; 

 more acute mandibles ; 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. 



777. Galerucites (Galerucites). Larva and
