170 Mr. 0. Salvin on new Species of Butterflies 



minal joint black ; head and prothorax black, with white spots; 

 thorax black, with a white central streak ; abdomen black 

 above, whitish beneath : anterior wings diaphanous, costal and 

 inner margins black ; a black oblong spot covers the end of 

 the cell ; outer margin black, deeply sinuated along its inner 

 edge, with semitransparent white spots in the sinuses ; a white 

 mark extends from the costa beyond the cell, over the radials 

 to the third median branch ; nervures black : posterior wings 

 diaphanous, nervures and border of outer margin black : be- 

 neath as above, the dark markings of the upperside being 

 fulvous instead of black : neuration of hind wing as in Itk. 

 andromica, Hew. ; lower discocellular atrophied at the extre- 

 mity ; middle discocellular appears as a projection at the 

 junction of the upper discocellular and upper radial ; the latter 

 are stout and well defined, the upper radial anchylosing with 

 the subcostal close to the margin of the wing ; the lower radial 

 is isolated and disconnected, appearing only towards the mar- 

 gin of the wing. 



5 . Like the male, but the dark markings rather broader, 

 and the apical portion of the anterior wings more clouded, but 

 leaving two clear spots : neuration of the posterior wing as in 

 ? ItJiomia andromica ; the middle discocellular nervule is ab- 

 sent, the upper and lower radials combine and then branch 

 into a fork halfway towards the margin of the wing. 



Hah. Valley of the Polochic River, Guatemala; Calobre, 

 Veragua [Arce] ; Costa Rica {Carmiol). 



Ohs. Closely aUied in structure and coloration to I. andromica , 

 but differs in being larger, the anterior wings being less pro- 

 duced and wider, and the dark markings and borders being 

 broader, and the white patch of the anterior wings narrower. 



14. Eresia nigripennis. 



^ . Exp. 2*45 in. Antennse black, the club yeUow; palpi 

 black, white on each side ; head and thorax black ; abdomen 

 brown, with a black line above and below : anterior wings 

 produced, apical angle rounded, black, with two series of in- 

 distinct spots beyond the cell yellow ; there is also a yellow 

 spot between the first and second median branches : posterior 

 wings tawny red, costal and outer margins black, two tawny 

 spots at the apical angle ; cilia of both wings white between 

 the nervures : anterior wings beneath tawny at the base on 

 each side of the median nervure, running into yellow between 

 the first and second median branches ; a series of eight yellow 

 spots round the outer margin, those in the apical angle elon- 

 gated and extending to the margin ; another series of elongated 

 spots between these and the end of the cell : posterior wings
