?)32 MR. H. W. BATES ON THE LEPIDOPTERA 



Var. 1. Same as 31. T'olymnlu, Cram., except that tlie ground-colour is of a dark orange- 

 brown, nearly as in 31. E(j(tensis. 

 This variety was numerously represented, and in both the sexes. 



Var. 2. Between var. 1 and 31. Bf/nei/.sis. 



The wings are dark isabella-colour, or orange-brown ; the black stripe along the hind 

 margin of the fore wing touches tlie edge for great part of its length ; and there is a large 

 irregular yellow spot, bordered with tawny, in the centre of the black apical part, liind 

 wing of the cJ more angular than in II. PoIi/Mi/if, the apex being as if truncated. 



Many examples of this variety occurred at Ega. Few were exactly alike ; some approach 

 J/. Egueiisis, and others the var. 1 above described. 



Local var. 3Iech<Mtlt'i)i 3Ia:(eiis, llewits. Exot. Butt. 3L'ch(uiU'iH, fig. 8. 



This form prevailed at St. I'aulo, 200 miles to the west of Ega, in the same way as 31. 

 Eijaeiisls did in its locality. There is a wide contrast in colour between the two varieties, 

 and at a first glance tliey would be pronounced distinct species. Examples occurred at 

 St. Paulo, however, which connected 31. 3I(i:ct'iis with 31. Tohj^nnla type. The other 

 varieties found at the same locality are so numerous that they cannot conveniently be 

 described in detail : some are intei-mediate between 31(i:icus and the var. 2 of 31. Erjaens'ts ; 

 others are remarkable for their rich colouring of l)lack, yellow, and orange-brown, the black 

 spots at the end of tlie fore-wing cell forming a belt, which divides the yellow part into 

 two sinuous belts. One (found paii-cd with 3£'i~(i'/f.i) rcscmljles 31. 3I('ii()p]iihifi (llewits. 

 Exot. Butt. 31('ch(niiti.s, iig. ;5). All of these varieties, however, have the marginal row 

 of white spots beneath ; and none agree with the 31. Ef/(te//.si,s'. The following merits a 

 separate name and description, on account of the modified shape of its wings. 



Local var. 3Ie('li(iiiiHs OUi-cncid. 



2 . Expanse 2" 10'". Similar in colours to 31. 3Iiiza'iis. Fore 'O'ing much shorter, the 

 apex being obtuse and the outer margin less oblique, so that the end of the cell is l)rought 

 much nearer to tlie ajicx, reducing the extent of the dark-coloured part near the apex : 

 orange-tawny ; the costal margin near the Ijasc and a l)road stripe along ^ths of the 

 posterior margin, touching the edge, black. There is a triangular spot in the basal part 

 of the cell, a large quadrate one in the middle, and a large twin spot across the v\u\ of 

 the cell, also black ; beyond the twin spot there is a sliort undulated licit of a rather ])alcr 

 tawny than the ground-colour, which is yellow near the costa, and bordered exteriorly 

 with black, the apical part of the wing beyond this belt being orange-tawny like the 

 ground-colour: there is a black spot in the angle betweiMi the 1st and 2nd median 

 brancbes, and a twin spot [)osterioi' to it, nearer the outer edge, of the same colour. 

 BciK'dth, the same, (^xcept that there are three white marginal spots near the apex. 



Illiig wii/(/ : dhori', the same; as in 3f. 3LiZ(C/is; bct/ral//, the same as above, excej)! that 

 th(i margin is destitute of white; spots, or has only a slight indication of them. iJody and 

 antenna! the same as in 31. PohitiniUt and all the varieties of it here described. 



J'^ouiid in company with the 31. 3r((Z(Cus at St. I'aulo. It is a variety of 31. Eohntinia, 

 which varies in an important part of structure.
