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-
