Special Structural Characters. 
Dorsal space narrow, especially centrally, lateral space broad, very 
oblique, subventral space very small, retracted; form much flattened, 
the principal part of the visible surface consisting of the lateral spaces. 
Outline elliptical; subdorsal ridge slight, lateral pronounced. Horns 
of both ridges extended laterally, those of the subdorsal ridge reduced 
in size, flattened, subequal, those of joints 8 and 10 slightly shorter. 
Lateral horns produced and flattened, slender, fringing the sides and 
touching the leaf when the larva is at rest, subequal, those of joints 13 
slightly longer. The spines on the horns are of the normal stinging 
type after stage I, but not strongly developed and they tend to degener-
