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 occupying most of the outer portion of the cell 
of the fore wing, is a light-colored area, marked ITI in the figures. 
This area is rufous in color in Fig. 49, but it is usually yellow, as in 
Figs. 46, 48, 51,54-57, and I have called it the “inner yellow.” 
Beyond the “inner yellow,” 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 yellow area (V), the “middle 
yellow,” and there is sometimes still another yellow patch beyond 
this, which is marked VI and called the “outer yellow.” Finally, 
one often finds a row of white or yellow 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, Napeogenes, Ithomia, and Meliraea. One more 
very characteristic marking of the fore wing remains to be noticed ; 
that is the longitudinal black stripe (VIII). Itis also worthy of note 
that the front costal edge of the fore wing is almost always tinged 
with black, c 
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 Lthomia 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
