This genus is well discriminated from the other 

 chrysomelinae by the character which has suggested 

 the name,* viz. the long conical horn projecting 

 from the breast. The species are peculiar to South 

 America, in some countries of which they are much 

 more numerous than the chrysomelae properly so 

 called. They are usually observed walking slowly 

 on the leaves of plants, and they permit themselves 

 to fall to the ground when one approaches. When 

 handled they discharge from the mouth a yellow 

 liquor of a foetid smell. The species above refer- 



, a pike-learer.
