Beyond the "inner rufous" we find a black spot, marked II in the 

 figures. It usually occupies the middle region of the cell of the fore 

 wing, and I have' designated it as the " inner black." Beyond the 

 "inner black," and occup^nng most of the outer portion of the cell 

 of the fore wing, is a light-colored area, marked III in the figures. 

 This area is rufo°us in cofor in Fig. 49, but it is usually yellow, as in^ 

 Figs. 46, 48, 51,54-57, and I have called it the " inner yellow." 

 B^vond the "inner veUow,"' and occupying the extreme outer 

 portion of the cell lies the - middle black " (IV) . In many species 

 it is fused, as in Figs. 46-48, 56, 57, with the large black area, the 

 " outer black " (VII) , which occupies the greater portion of the outer 

 half of the fore wing. Just outside of the cell beyond the " middle 

 black" one finds a well-developed yeUow area (V), the " middle 

 yellow," and there is sometimes still another yellow patch beyond 

 this, which Ls marked VI and called the " outer yellow." Finally, 

 one often finds a row of white or yeUow spots, the " marginal spots" 

 (IX), lying very near the outer margin of the fore wing (see Figs. 

 47-49, 51,'' 54, 56). These spots are very well developed in the 

 genera Ceratinia, Xapeogenes, Ithomia, and MeUnaea. One more 

 very characteristic marking of the fore wing remains to be noticed ; 

 that is the longitudinal black stripe ( VIII j . It is also worthy of note 

 that the front costal edge of the fore wing is almost always tinged 



with black. 



The pattern of the hind wing is quite simple. The ground color 

 is usually rufous and a "middle black" band (XI) runs across the 

 middle of the wing. The outer edge is bordered by the "outer 

 black" (XIII). Above the "middle black" band lies the " inner 

 rufous " (X) of the hind wing, and below the " middle black " band 

 one finds the " outer rufous " (XII) of the hind wing. One often 

 finds a row of white or yellow dots within the outer black border of 

 the hind wing, and these I designate as the " marginal spots " of the 

 hind wing. 



The Ithomia type of coloration, it will be remembered, may be 

 derived from the Melinaea, by simply imagining the rufous and 

 yellow areas to have become transparent. Also the outer black 

 usually suffers a reduction so as to become only a rather narrow 

 border along the outer margin of the fore wing. Thyridia psidii 

 (Fig. 47) is°a good example of this type. It will be seen that the 

 black areas remain about the same as in the Melinaea type, but that
