pillars are of that tribe which march rank entire. 

 They sometimes advance in straight lines, and at 

 others in curves of various inflection. They are of 

 a fiery colour, which gives them the appearance of a 

 cord of gold, extended on a silken fillet, of the most 

 immaculate whiteness. It is when travelling on this 

 carpet of silk, to feed on the leaves of their favourite 

 plants, that this appearance is exhibited. The 

 Piti/ocampa, another moth which congregates in a 

 common receptacle of pine leaves, united by fila- 

 ments of silk which they spin, is also of this military 

 order. They follow each other in a variety of mazy 

 turnings, which gives the most animated picture of 

 ever varying living wreaths. The whole chain of 

 caterpillars move in unison, and at a proper distance 

 from each other, in the most perfect order; and when 

 their leader stops, the whole halt in an instant.*
