OF UNFIGURED LEPIDOPTERA. 



by a dark line which extends down to the lower angle one-sixteenth of an inch 

 within the hind margin. 



On the under side of the hind wing, the black line noted on the upper surface 

 is repeated. Below this, the area to the row of black spots is dull yellow. 

 Below this spot the area to the black marginal border is light tawny. In the 

 black hind marginal border is a wavy line extending from the anal angle through 

 four interspaces. 



Variations. The chief variations are due to the suffusing of the 

 ground color on the black portion, or vice versa. Some specimens 

 are more or less suffused, thus having the markings indistinctly out- 

 lined. I have one specimen in which the row of black spots on lower 

 wing is totally wanting on the upper surface, although it is slightly in 

 evidence on the under surface. This species could not be found in 

 the large collections of this country, nor the British Museum, nor has 

 any description by a previous author been brought to light. 



Ithomia hamlini A. G. Weeks, Jr. 1 



(Plate 77, Two Figures^ 

 Habitat : Suapure, Venezuela. Expanse : 2 inches. 



Head black, with a yellow dot behind the eyes, also one between the antennae. 

 Eyes surrounded by a yellow thread. Antennae dark brown, merging to light 

 brown towards club. Club black, with brown tip. Thorax above black, with a 

 yellow collar and a yellow spot at junction of each costa; beneath, lemon 

 yellow. Abdomen above black ; beneath, lemon yellow. Legs, black. 



Upper side of fore wing mostly transparent, marked with brownish black and 

 yellowish transparent areas. Costa black, edged with brown along discoidal 

 space. Discoidal space transparent, with a yellowish tinge. From the base of 

 wing a dark club-shaped dash extends upward to centre of discoidal space. 

 From the centre of costa a broad brownish black band extends downwards 

 across the end of discoidal space, terminating at hind margin just above the 

 lower angle ; the nervures and nervules in this band are black. Outside of this 

 band is a broad transparent area, heavily dusted with lemon-yellow scales near 

 costa. The apical area and hind marginal area are brownish black, with a 

 slight suggestion of lighter spots in the interspaces near margin. The median 

 nervure is brown. The inner marginal area below the median nervure is brown 

 suffusing to dense black toward inner margin. 



The upper side of hind wing has the same colors. The hind margin is 

 bordered with a sixteenth of an inch brownish black border, bearing suggestions
