pletely from the parental stock, L Orolina, and inhabits a distinct area of country. 
Ithomia Cidonia (Hewitson, Exot. Butt. Ithomia, fig. 122), of New Granada, is another 
local race of the same stock. I. Sarepta comes nearest to I. Aureliana, and J. Cidonia 
to I. Chrysodonia. The five varieties found mingled together at St. Paulo cannot be thus 
separated, although they show, as we have seen, differences of structure as well as of 
colour and markings. They form a graduated series, and have not reached the stage of 
complete segregation. The differences in the veining of the wings are evidently the 
correlated result of the altered shape and increased or diminished size of the wings, 
consider this Orolina group of Ithomice to be nearly equivalent to the IUmissa group ; 
the difference between the present condition of the two is that in Ithomia Orolina and 
its allies the segregation of the forms is only partially complete, whilst in I. Illinissa and 
its kindred it is almost perfectly so. ' 
A variety of Leptalis Lysinoe {L. Urythroe, PL LVI. figs. 1, 2, 3), a Napeogenes (N. 
Corena), and a Bombycide Moth (Dioptis, n. sp.), all assimilated in colours to L. Oro- 
lina and its varieties, occur in company with them at St. Paulo.

23. Ithomia Nephele, n. sp. 
cf $ . Expanse 2" 5"'. Hyaline, slightly fuliginous. Fore wing with a narrow black 
border, which is broadest along the hind margin ; there is a short, broadish, oblique black 
belt across the end of the cell, and beyond this an oblique chalky-white belt, beginning 
on the costa, where it forms an opake white stigma, and nearly reaching the middle of 
the 3rd median branch ; the nervures which it traverses are also white ; the 2nd and 3rd 
median branches, as well as the rest of the nervures, are black ; there is also a series of 
obscure whitish spots between the nervures, near the outer border. Beneath, the black 
borders and belt are reddish orange. 
Bind wing with a narrow, clearly denned black border, which beneath is reddish 
orange. 
Body and antennae black ; head and thorax marked with white.
