Hab. Panama, Chiriqui (Bibbe 1 ). 



A single female specimen in Dr. Staudinger's collection obtained by Herr Kibbe in 

 Chiriqui is the only example we have seen of this insect. It is allied to D. theonoe, 

 but the diaphanous portion of the basal half of the primaries is much more extensive, 

 the apical spot on the primaries is very small, and there is no spot on the costa near 

 the apical angle of the secondaries. 



6. Dismorphia sororna.

Hab. Costa Rica ( Van Patten 1 ). 



A male and four females of this fine species were contained in Van Patten's collection 

 from Costa Rica, and formed the types of Mr. Butler's description. Both it and the 

 following species are evidently allied to D. cordillera of Felder from Colombia, but they 

 both of them differ in having the apical spots yellow in both sexes instead of white. 

 The females have a strong resemblance in the outline of the wings, and in their colora- 

 tion, to various butterflies of the genera Tithorea, Ceratinia, Olyras, Heliconius, JEueides, 

 Eresia, &c, all found in the same region. D. sororna differs from B. myris in having 

 the cell in the region of the median nervure black; beneath the secondaries are 

 destitute of the large ochreous median patch prominent in the allied species.
