Special Structural Characters. 



Dorsal and lateral spaces broad, subventral space narrow, con- 

 tracted; ridges very slight, the lateral the most distinct, approximate 

 to the subventral. Fleshy horn-like processes at first equal, later the 

 terminal ones elongate, the others short : in stage I bearing three 

 setae each, after first molt the subdorsal and lateral rows covered 

 with numerous urticating spines; subventral row rudimentary. The 

 subdorsal horns are long on joints 3 and 13, short and equal on the 

 rest: lateral horn long on joint 3, short on the rest, no lateral horn on 

 joint 5j the spiracle moved up in its place. Depressed areas feebly 

 developed, usually only the glandular centers visible and only those 

 of the centers of the dorsal and lateral spaces visible. Skin at first 

 smooth, finally with rather dense colorless granules. Caltrope patches 

 appear on the lateral horns about stage VIT and are well developed in 

 the last stage, when four patches of dense spines appear above the 

 subdorsal horns of joint 13 and lateral of 12 on each side. 



The eggs are elliptical, flattened, but of thickness equal to half of 

 the narrow diameter, laid in masses and covered with hair-like fila- 

 ments from the parent moth.
