PLATE 9. 



iJiagrams to illustrate color-variations. 



The various colors are laid off at definite intervals along the axis of abscissae, 

 and the ordinates represent the number of species which exhibit the various 

 colors. 



Fig. 97. Represents the color-variations of the •' inner rufous " area of the fore 

 and hind wings in the Danaoid Heliconidae. The full line represents 

 the variations of the fore wing. The dotted line those of the hind 

 wing. The closeness of these two lines shows the intimate relations 

 between the color-variations of the " inner rufous " areas upon fore 

 and hind wing. See p. 218. 



Fig. 98. The full line represents color-variations of " inner yellow " spot of fore 

 wings in Danaoid Heliconidae. The dotted line represents same for 

 " middle yellow." It is apparent that the - inner yellow "' is more 

 variable than the -outer yellow." and also that the variations of 

 both are quite similar to those of the "inner rufous." See p. 219. 



Fig. 99. Color-variations of " inner rufous " areas of Acraeoid Heliconidae. 

 The full line represents the fore wing and the dotted line the hind 

 wing. See p. 218.
