76 THE CANADIAN ENTOMOLOGIST. 



NEW LEPIDOPTERA. 



BY ANDREW GRAY WEEKS, JR., BOSTON. 



Adelpha Oro7ioco, sp., no v. 

 Habitat: Suapure, Venezuela. Expanse, 1.60 inches. 



Head and thorax dark brown above, with a sHght 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. xAntennse dark brown. 



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

 brown ground colour, 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 upper surface. The portion of this band in the 

 interspace at the end of the discoidal space suffuses outwards a sixteenth 

 inch towards hind margin. Above the end of this, in apical area, are two 

 tawny spots. These spots might be considered a portion of the band but 

 broken from it by an area of the ground colour. The basal half of the 

 wing, within the tawny band, is rich brown excepting four black lines 

 which cross the discoidal space in pairs, and a slight dash of black close to 

 base. This dash is repeated in less degree in the next lower interspace. 

 The pair of black lines next beyond this dash enclose a small space of 

 dark tawny ; these lines are repeated in the first submedian interspace. 



The upper side of lower wing is of the same ground colour, crossed 



by a very prominent band of white, an extension of the tawny band of the 



fore wing, and tapering somewhat as it approaches anal angle. The outer 



edge of this band at its upper portion is lightly dusted v/ith tawny scales. 



The marginal area outside of this band is rich brown, crossed by three 



bands or lines of black, parallel to one another and following the dentated 



contour of the hind margin. They join at the anal angle, where there is a 



prominent tawny spot. The inner marginal area is of the ground colour. 



On the under side of fore wing the tawny band of upper surface is 



nearly white, with suffusions of tawny. The discoidal space is white, 



crossed by\wo heavy bands of tawny, edged with black. The costa is 



lawny. Subcostal space near base is white. The hind margin is slightly 



edged with black, within which is a tawny marginal band, becoming white 



in the two lower interspaces. Within this, at the apex, are two indistinct
