The head is bhick. The general color of the body ashy violet, 

 with three straight, longitudinal, black, fine lines, parallel to each 

 other, one dorsal and the other two lateral, interrupted only in the 

 first four segments; between the shield on the first segment (which 

 shield is black), and the head, there is a yellowish white band, from 

 which protrude fleshy protractile horns of an orange color, and at 

 its extremity a white appendage of one millimeter in length. Each 

 of the second and third segments have also four appendages curved 

 backwards and shaped like a thorn, of white color with a black 

 stripe in front and behind, the two central ones in each segment 

 being five millimeters in length, and the other two a little shorter.

 with gray borders, another violet band followed by a line like the 

 others, but horizontal ; and then another daik band divided by a 

 little black stripe with light borders, in the lower part of which band 

 are situated the stigmata, which are black and of oval form, wath an 

 ash colored centre ; lastly, a white band with a slight pink hue and 

 little black stripes, which band extends from the head to the anal
