one runs parallel to these and is of similar extent. The first and third are 

 covered with white or very light blue hairs, the central or second one having 

 scaling only. The hind margin is well dentated towards anal angle, >he inter- 

 spaces touched with white. Well within it is a line of blue scalings well broken 

 by the nervules, a continuation of the same markings of fore wing. Near upper 

 angle betwixt this line and the outer one of the three prominent dashes is a 

 dash of blue scales, starting well below the costa and running a quarter inch 

 downwards towards anal angle. 



Under side of fore wing black but not as rich as upper surface. General 

 markings the same. Basal blue area of upper surface is represented only by 

 blue at base of costa and a blue diagonal dash beyond. The inner marginal 

 area is dark mouse color except towards lower angle. The dashes of blue 

 noted in the two lower interspaces of upper surface are wanting. 



Under side of hind wing black. The appearance of the wing is quite different 

 from upper surface as the prominent dashes of brilliant blue are quite altered. 

 There are three bands, one starting at costa at base and extending downwards 

 until by a slight inward curve it strikes lowest submedian nervule about midway 

 to lower angle ; the next band runs downwards from costa, practically the same 

 in area and extent as the first, ending at centre of wing area at the end of 

 discoidal space ; the third band represents the hind marginal blue line of upper 

 surface, but is much more prominent. Inner margin edged with brilliant blue. 



This species is very close to E. distant Herr. Schaff., and also E. 

 pygmaleon Hew. The group is open to much interesting future work 

 for those who locate in its region. 



Adelpha oronoco A. G. Weeks, Jr. 1 



(Plate XIV.) 

 Habitat : Suapure, Venezuela. Expanse: i. 60 inches. 



Head and thorax dark brown above, with a slight white dot at base of each 

 antenna ; below, nearly white. Palpi black above, white below. Abdomen dark 

 brown above, below nearly white with a dusting of tawny scales on the last 

 two segments. Antennae dark brown. 



The upper side of both wings has the black linings or threads, the brown 

 ground color, and tawny markings so prevalent in many species of this 

 genus. 



Upper side of fore wing rich brown. Hind margin slightly dentated. From 

 the centre of costa a broad tawny band extends downwards to centre of inner 

 margin parallel to hind margin. This band is the prominent feature of the
