OF THE AMAZON VALLEY. 555 



orange-brown colour, more or less suffused with black ; one variety is so distinct tliat it 

 merits a distinctive name, as follows : — 



Var. H. Pardalimts. 



(S . Similar in size and shape to H. Nmnata and Eucoma. Fore icing : above, rich 

 orange-brown ; the basal half of the costal margin, a broad stripe on the hind margin, 

 broadest in the middle, and an irregular border along the outer margin black; an 

 elongate spot within the cell touching the base, a quadrate spot at the end of the cell, 

 and two rounded spots, one between the 1st and 2nd, the other between the 2nd and 3rd 

 median branches, also black ; beyond the cell is an oblique bright-yellow belt, consisting 

 of five elongate spots, and between it and the apex is a second yellow belt of four smaller 

 spots : the outer edge of the first belt, the nervures beyond it, and an irregular spot 

 around its extremity are black. Beneath, the same. 



Sind icing : above, rich orange-brown ; a stripe along the costa, a broad central one, and 

 a marginal series of very large connected angular spots black. Beneath, the same, 

 except that there is on the hind margin, towards the anal angle, a series of ten short 

 yellowish-white lines. 



Body and antennae as in H. Nmnata. 



The rich orange-brown colour of the apical part of the wing, divided into spots by the 

 dark lines which accompany the nervures, gives a distinct appearance to this form, which, 

 however, in all essential points is very closely allied to K. Eucoma. It is found in 

 company with S. Eucoma at St. Paulo. It very much resembles Ilelincea Pardalis of 

 the same neighbourhood. 



4. Heliconius Aurora. 



S . Size and shape of JI. Nmnata. Fore wing : above, clear tawny orange ; the basal 

 haK of the costa, a broad stripe on the hind margin, touching the edge, but not reaching 

 the hind angle, an elongate spot at the base of the cell, a stripe across the end of the 

 cell, from the costa to the outer margin, consisting of two elongate spots which meet 

 at the hind angle of the cell, and the apical fourth of the wing black : in the middle of 

 the black apical portion is an elongate yellow spot, crossed by four nervures. Beneath, 

 the same ; margin spotless. 



Hind wing : above, clear tawny orange ; a subcostal stripe, bent before the apex towards 

 the upper radial, and a very large rounded spot occupying more than the anal half of 

 the wing, black. Beneath, the same ; margin spotless. 



Body and antennae precisely the same as in S. Nmnata and the allied species and 

 varieties. 



This apparently distinct species occurred at St. Paulo ; it has a striking resemblance 

 to Melincea Lucifer of the same locality. It agrees in all essential points with S. Numata, 

 and is most likely a modification of that species ; but the intermediate connecting forms 

 are wanting.
