196 ENTOMOLOGICAL NEWS. [June, '06 



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 collec- 

 tions of this country, nor the British Museum, nor has any 

 description by a previous author been brought to light. 



Ithomia hamlini sp. nov. Expanse 2 inches. Head black, with a yel- 

 low dot behind the eyes, also one between the antennae. Eyes surroun- 

 ded 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 wkh 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, termi- 

 nating at hind margin just above the lower angle ; the nervures and ner- 

 vules 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 mar- 

 gin is bordered with a sixteenth of an inch brownish black border, 

 bearing suggestions of lighter spots in interspaces. Inside of this, toward 

 the base of the wing, is a band of brown extending from the upper angle 

 downward, and swinging across the wing to the anal angle parallel to 

 hind margin. Still nearer the base, bordering this brown band, a darker 

 band runs across the wing horizontally, turning upward to the costa well 

 outside the discoidal space. The discoidal space and the area surround- 

 ing it is transparent, slightly dusted with brown scales. The nervures 

 and nervules are brown. 



The under side of both wings is the same as upper surface, except that 

 the interspacial light spots along the hind margins are more distinct, be- 

 ing very prominent on the lower wing. 



Hab. Suapure, Venezuela. 



Variations. The sixty specimens in my collection show no 

 variation in size. The markings are identical in shape and 

 location, but show considerable variation in their density and 

 tendency to suffusion. The typical specimen above described 

 is a fair average.
