18/8.] DIURNAL LEPIDOPTERA FROM CENTRAL AMERICA. 267 



to the apical angle, extends halfway along the outer margin. Be- 

 neath the difference between the two species is more obvious ; the 

 whole under surface of the secondaries in P. triaria is dark brown 

 mottled with black, two broken black bands crossing the wings, one 

 through the cell, the other beyond it ; a row of six submarginal 

 ocelli with white pupils, that between the first and second median 

 branch being much the largest and most conspicuous ; the mottling of 

 the apical area of the secondaries is upon a yellowish ground-colour ; 

 the light ground-colour at this part, and over the distal third of the 

 secondaries in P. praxithea is wanting. 

 Hab. Costa Rica, Irazu (H. Rogers). 



6. Pedaliodes cremera. 



$ . Exp. 2 - 9 in. Primaries entire, apical angle somewhat produced, 

 outer margin of secondaries sinuated ; dark brown ; primaries crossed 

 by a broad submarginal band of obscure tawny, the inner edge of 

 which is concave, and the outer serrate running parallel to the outer 

 margin : beneath mottled with blackish brown, in the tawny band 

 of the primaries, between the first and second median branches is a 

 white-pupillated ocellus; an irregular dark line follows the outer 

 margin of the secondaries halfway between the outer margin and 

 the cell ; between the first and second median branches near the 

 margin is a large black ocellus with a white pupil, and two smaller 

 ones near the anal angle. 



Htb. Costa Rica, Irazu (H. Rogers). 



7. OXEOSCHISTTJS ROGERSI, Sp. n. 



2 • Exp. 3 in. Allied to 0. phaselis (Hew.), differing above in 

 having a conspicuous row of tawny oval spots, separated by the 

 nervules running parallel to the outer margin, the three spots sepa- 

 rated by the first and second median branches, and that between the 

 middle and upper radials bearing large dark brown spots of the same 

 brown coloui as the rest of the wings : beneath, the markings re- 

 semble those of O. phaselis, except that the marginal region of the 

 primaries is strongly marked with fulvous corresponding with the 

 markings of the upper surface. 



Hab. Costa Rica, Irazu (H. Rogers, type mus. nostr.) ; Chiriqui 

 (Ribbe : mus. O. Staudinger). 



Dr. Staudinger's Chiriqui specimen exactly resembles ours, except 

 that it is rather paler, being not so fresh. 



O. phaselis has been placed in the genus Pronophila by Mr. 

 Hewitson, and in that of Dcedalma by Mr. Butler (Cat. Satyr, p. 

 184); but, so far as we can see, its proper place is in the genus Oxeo- 

 schistus, with the members of which it agrees in neuration, and with 

 some of them in style of coloration.

8. Phyciodes thebais, sp. n. 



Exp. 15 in. Allied to P. orseis, Edwards, ex California, as to the 

 position of the marks of the upper surface, and as to the coloration of
