interspacial white spots, and in the black border of the hind margin of the lower 

 wing is a series of prominent interspacial white spots. 



Variations. This species varies greatly in the density and suffu- 

 sions of its markings. The transparent area of the lower wing in some 

 specimens extends downwards to hind margin, cutting off the black 

 band and the tawny area at the first submedian nervule. The white 

 spots at apex of the under side of fote wing are at times entirely 

 wanting. 



Nymphidium quinoni A. G. Weeks, Jr. 1 



(Plate XVII, Figure i.) 

 Habitat: Suapure, Venezuela. Expanse: i. 3 p inches. 



Head and thorax above, dark brown; beneath, white. Abdomen above, 

 brown, slightly lighter than thorax; beneath, white. Antennae dark brown, 

 with somewhat lighter tip and very minute white annulations at base of each 

 joint. Legs white. 



Fore wings above creamy white, excepting the costal and hind marginal 

 areas, which are light brown, with darker markings and spots. The brown of 

 the costal area is well developed, covering nearly all the discoidal space, darker 

 at costa than below. In the discoidal space close to the base is a black dot; 

 beyond this, near centre of discoidal space, is a large black spot; at the end of 

 discoidal space is a black line, and this line, with a little of the surrounding 

 brown area, extends downwards into the creamy white ground color, forming a 

 knob more or less prominent. The apical and hind marginal areas are light 

 brown, edged with darker brown on the basal side. Down the central part of 

 the brown hind marginal area runs a line of interspacial black dots. The hind 

 margin bears a dark border distinctly touched with white at end of the first 

 and the lowest submedian interspaces. Inner margin creamy white. 



Upper side of hind wing creamy white. The hind margin has a generous 

 brown border, a continuance of the same on the fore wing and identical in every 

 respect, including the interspacial black dots, the marginal white markings, etc. 



The under side of both fore and hind wings is the same in its markings as 

 upper surface, but the white lacks its creamy tinge, and the marginal border is 

 nearer mouse color than brown. The colorings of upper surface are repeated 

 but decidedly deadened, and this deadening of under surface color is too well 

 known to need any detailed description. 



The interspacial dark marginal spots are more prominent, owing to the lighter 

 background. The dark edging of the hind margins is also more noticeable, 

 and the white marginal spots of upper surface are much more prominent.
