298 RHOPALOCERA. 
Hab. Costa Rica, Cache (Rogers1); Panama, Bugaba (Arcé).—Co.omsia 1. 
An interesting species, combining the characters of several others. On the upper- 
side it closely resembles A. tizona, A. salmoneus, &c.; the underside, however, is like 
that of A. epione. Our first specimens were derived from Costa Rica and Colombia ; 
we now know it from the neighbourhood of Chiriqui, and we have also additional 
examples taken by Salmon in the Cauca valley. 
4. Adelpha tizona. (Tab. XXIX. fig. 11.) 
Heterochroa tizona, Feld. Reise d. Nov. Lep. p. 424°. 
Alis supra A. sophaci simillimis; subtus valde distinctis, maculis anticarum ad basin indistinctis, obscure 
cinereis maculis inter‘’ramos medianos nullis, posticis ad basin griseis, lineis transversis cellulam trans- 
euntibus haud ad marginem internum productis. 
Hab. Panama, Bugaba (Champion).—Cotompia!; Perv. 
A species of not uncommon occurrence in the neighbourhood of Chiriqui; but we 
have not yet met with it elsewhere within our district. We have examples from 
Colombia, one of which has been compared with Dr. Felder’s type. The species also 
occurs in Southern Peru, Mr. Whitely having found it in the Cosnipata valley. 
As already stated, A. tizona bears a strong resemblance to A. salmoneus on the upper- 
side; but they may be distinguished by the markings on the underside of the secon- 
daries, as will be seen on reference to the figures of the two species. 
It is also very similar to A. sophax on the upperside, but beneath differs considerably, 
as the figures show, that of A. tizona having been taken from a Chiriqui specimen. 
It is a forest butterfly. 
5. Adelpha salmoneus. (Tab. XXVIII. figg. 3, 4.) 
Heterochroa salmoneus, Butl. P. Z. 8. 1865, p. 667, f. 1°. 
A, sophact similis, quoad picturam alarum pagine superioris; subtus alis omnino rufescentioribus, lineis trans- 
versis magis indistinctis, maculis ad cellule finem anticarum duabus nec una diversa. 
Ab A. tizona differt alis subtus rufescentioribus et lineis posticarum transversis usque ad marginem internum 
productis. 
Hab. Guaremaua, Yzabal (F. D. G. & O. S.); Nicaragua, Chontales (Belt).—Co- 
LOMBIA; VENEZUELA 1, 
An ally of A. tizona and A. irmina, the differences being chiefly in the markings of 
the underside of the secondaries; these will be best seen by reference to the figures. 
A. salmoneus seems to be everywhere a scarce species; Mr. Butler’s type came from 
Venezuela +, and we have specimens from Colombia. Mr. Belt obtained a few examples 
of it in Nicaragua, and a single insect captured by ourselves at Yzabal in Guatemala is 
the only evidence we have of its occurrence in that country.
