1879.] NEW SPECIES OF RHOPALOCERA. 151 



tawny spots, the secondaries ave crossed by a median and a submar- 

 ghial bands, which are divided by the tawny subraedian branches ; 

 these bands in some specimens are almost confluent. 



Hab. Yquitos, Upper Amazon (?F"^?7e/?/). 



This is one of the numerous forms of M. maelus found in the 

 Upper Amazon and Lower Napo. Having six specimens from these 

 countries all closely resembling one another, we think it necessary 

 that this form should bear a name. 



Melin^a cydon. 



6 . Exp. 3"3 in. Allied to M. pardalis (Bates, Trans. Linn. 

 Soc. xxiii. p. 552), but differing in the absence of the yellow cross 

 belt of the primaries, the only yellow markings on the wing being re- 

 stricted to a subapical series of three spots. The tawny brown 

 markings of both wings are rather more clearly defined than in 

 M. pardalis ; and the central black cross bar of the secondaries is 

 generally distinct from the black outer margin. 



Hab. Tabatinga (Bates) ; Pebas {Hauxwell) ; Yquitos {Whitehj). 



This is the race alluded to by Mr. Bates under his description of 

 M. pardalis. At that time he did not seem to have considered it suffi- 

 ciently distinct to separate it; but since then additional examples 

 have come to hand, which point to the conclusion that this race is 

 as well-defined as M. pardalis itself. The same degree of local 

 differentiation is to be seen in Ceratinia tigrina as compared with 

 C. fluonia. Li Heliconius pardalinus a similar state of things is to 

 be found. 



Eresia laias. (Plate XIV. fig. 1.) 



Exp. 2 in. Allied to E. carme (Doubl. and Hew.), differing in 

 the arrangement of the spots of the primaries : a large patch of ful- 

 vous occupies the apex of the wing, between which and the inner 

 margin lies a larger oval patch, its axis parallel to the outer margin ; 

 beyond the cell is a small fulvolis spot, obsolete in some specimens. 

 Beneath the colour-pattern is much as in E. carme ; but the fulvous 

 base of the primaries extends interruptedly almost to the outer mar- 

 gin, but does not include the spots in the apex. In E. carme there 

 are distinct spots near the anal angle. 



Hab. Frontino, Columbia {T. K. Salmon). 



\delpha hypsenor. (Plate XIV. fig, 2.) 



Exp. 2-9 in. Allied to A. lara (Hewitson), but differing on the 

 upperside in having the transverse extra-cellular baud on the 

 primaries white, instead of red ; this white band is divided by dark 

 nervules, and on its outer edge especially, where it approaches the 

 outer margin, is tinged with fulvous. Beneath, the baud of the 

 primaries is white instead of pink as in A. lara, and the basal half 

 of the secondaries is yellower. 



Hab. Frontino, Columbia {T. K. Salmon). 



Pyrrhopyga rufinucha. 



Exp. 2'4 in. Body bluish black ; palpi black ; a rufuus spot at the
