The only addition to Blandford's list is a sub-species* of 

 Meli/h'va pardcdis frora the Rio Madeira to theS.E. of Ega. 

 The principal features of this association are the darkening 

 of the ground colour into a mahogany or chestnut tint, and 

 the mottled appearance of the outer half of the fore-wing, 

 this latter effect produced by broken irregular yellow 

 markings on a dark background. The black markings of 

 the North-Central American type are still visible on the 

 hind-wing, but they are more heavily developed and often 

 tend to fuse together, as in the Guiana Combination. As 

 usual, the Melinxa and Hcliconivs stand out as the central 

 pair, H. pardaliims (Figs. 8 and 9) resembling M. 2wrdcdis, 

 sub-sp. madeira (Fig. 2) in a most remarkable manner ; but 

 the whole of the Ithomiines form with the Heliconius and 

 the Dismorpliia (Figs. 6 and 7) a w^onderfully close combina- 

 tion. The yellow spot at the anal angle of the fore-wing 

 in the two species of Melinxct appears in the Lycorm 

 (Fig. 1), while in the Heliconius two spots are placed at 

 the apex of the hind-wing. In the natural position of
