colour of the wings, the very diiFerent form of the white band, 

 and the absence of numerous ocelli. 



Genus Heterochroa, Boisduval.

Upper side dark brown, with a central band of white common 

 to both, which, commencing at the median nervoire of the ante- 

 rior wing in the form of a distinct triangular spot, curves slightly 

 inwards and extends to the anal angle of the posterior wing, 

 where it is followed by an irregular patch of orange. 



On the anterior wing, between the commencement of the white 

 band, the costa and the apex, is a triangular patch of orange, 

 cut into foui* by nervures, convex on its outer margin, and 

 nearly touching the white band with its acute angle. Parallel to 

 the margins of both wings are the usual black lines. 



Under side of a glossy silver, divided into three broad irregular 

 bands — each bordered by deep black — by two narrow belts of 

 crimson, the middle band occupying rather more space than the 

 white band and the orange spot of the upper sides together ; the 

 marginal band, which is obscured in tbe middle of the anterior 

 wing, is again divided longitudinally by a black line, and also 

 perpendicularly by the nervures. In the cell of the anterior 

 wing is a square silver spot, cut into three triangles by a curved 

 black line, and outside of this two silver spots, one minute. 

 Exp. 2/o inches. 



In my own collection. From Rio de Janeiro. 



This beautiful species, though veiy nearly allied to H. Iphicla 

 of Cramer (//. Serpa, Boisduval), is abundantly distinct.

Upper side deep brown, with a common central band of white 

 pointed at each end, commencing at the median nervure of the 

 anterior wing in a minute oval spot, and extending to the usual 

 rufous patch at the anal angle of the posterior wings ; between 

 the commencement of this band, the costal nervure and the apex 

 of the anterior wing, is a triangular patch of orange not divided 

 by nervures, the acute angle of which, though nearly approach- 

 ing the white band, is separated from it by a broad line of black. 



Under side ferruginous — lightest under the orange patch j 

 the central band pure white, and prolonged upwards to the ex- 

 treme costal margin of the anterior wing by a line of silver ; two 

 silvery belts cross the cell of the same wing and extend beyond 

 it, that nearest the base being common to both wings ; these belts
