PLATE 2. 



Diagrams to illustrate the laios lohich governthe Color-Patterns of Lepidoptera. 



Fig. (>. Euthalia bellata (\V. L. Distant, '82-'86, Plate 43, Fig. 12). Illustrates 



the law of bilaterality of spots. See p. 183. 

 Fig. 7. Zethera musa (G. Semper, '86-'92, Taf. 7, Fig. \0\ Bilaterality of 



double spots. See p. 183. 

 Fig. 8. Eye-spots in Morpho. See p. 182, 183. 

 Fig. 0. Parthenos gambrisixis (W. L. Distant, '82-'86, Plate 11, Fig. 7). A series 



of complex spots, each one being similar to the rest, and bilaterally 



symmetrical. 

 Figs. 10. 11. Omithoptera urvillana and O. priamu.s (R. H. F. Ripon, '89-93). 



Spots ■\Arithin .spots, all being bilaterally symmetrical. 

 Figs. 12, 13. Hestia jasonia and H. leuconoe. Axis of lateral symmetry 



(H, H),for spots passes through center of intersptce. H. jasonia 



(F. Moore, '90-'96, Plate 3. Fig. 1). H. leuconoe (G. Semper, 



'86--92, Taf. 1, Fig. 3). 

 Fig. 14. Papilio emalthion, to illustrate fusion of tAvo rows of spots. 

 Fig. 15. Omithoptera trojana, an apparent exception to the law of bilaterality. 



See p. 187. 

 Fig. IH. Limenitis proserpina (S. H. Scudder, '88-'89, Plate 2, Fig. 9), showing 



fusion of two rows of differently colored spots. See p. 187. 

 Fig. 17. Saturnia spini, false eye-spot. See p. 187. 

 Fig. 18. Cases of degeneration of bands of color. See p. 184. 

 Fig. 19. Missanga patina (F. Moore, '90-'96, Plate 72, Fig. 2«). Exceptional 



form of eye-spot. See foot note p. 180. 

 Figs. 20-23. Hypothetical conditions of coloration, not found in nature, being 



contrary to the laws of color-pattern. See p. 188.
