and produced into a pointed tail. Anterior portion of body humped 



up. Ancestral colors replaced by a protective brown, relieved by a 



fiery patch posteriorly. Skin spinules converted into granules only 



along the subventral edge. 

 Q. Moiiolcitca scniifascia is somewhere in this position ; the larva is 



unknown. 

 R. Origin of a larva not yet bred. Terminal horns long; shape 



elongate, not humped. Coloration as in Adoneta spinitloides, but 



the five purple patches about eciual in size. 



a. The main stem of the smooth Eucleids. Differs from stem A in the 

 tendency to reduction of the warts and increased development of the 

 depressed spaces. Skin granular. Color green. 



b. Proliinacodes srapha. Lateral space obliterated, a high ridge fonned 

 . by the union of subdorsal and lateral ridges. Primitive first stage 



absent ; small warts present in stage I, afterward only the primitive 

 setse, the warts obsolete. Depressed spaces developed into plate- 

 like structures, the granules resembling overlapping scales. De- 

 pressed spaces (9) and (10) added. Color green, variegated with 

 yellow and brown. 

 C. The main stem of the pakearctic Eucleids. Warts absent, the nor- 

 mal primitive setce present after stage I. The modified primitive 

 first stage retained with the subdorsal Y-shaped spines. Glandular 

 dots of depressed spaces (t) united into a single center, the spaces 

 (l) to (8) moderately developed. Skin granules somewhat spinose. 



d. One limb of the Y-shaped spines of stage I reduced to a slight 

 prominence. Depressed spaces moderate only ; no red marks in the 

 dorsal space. 



e. The Y-shaped spines retained in stage \. Depressed spaces enlarged, 

 deep, sharp edged, reducing the intervening surface to a series of 

 latticed ridges. A red dorsal patch. 



f . Skin gi anules discreet or subpapillose, simple. 



g. Skin granules divided, forming a tuft of spines on the apex of each, 

 simple in the last stage. 



h. Ileferiv^enca shtiiileffii. A transverse yellow line on joint 3. Out- 

 line smooth in the last stage. 



i. Kroiura iiiinitta, its probable position. 



j. I'oiiricidia Jleuu'Sti. Granules never papillose; setffi practically 

 absent at first molt. Dorsal red mark moderate. 



k. Grnnules subpapillose, setic small, but distinct for several stages ; red 

 mark large. T. hs/acea and T. pullida differ only in the shape of 

 the mark. 



1. Skin granules still produced into spines. 



m. Lithacodes fasdola. Skin shagreened granular besides the ancestral 

 spines. Subdorsal yellow lines joined in front.
