Of the fifty-five forms placed under the former, some 

 thirteen show a slight reduction of the band, but still classed 

 as diana, while a further seventeen are wholly intermediate 

 between dianides and diana. 



Heliconius melpomene cybele ab. maris, nov. 

 (Plate CVII, fig. 4.) 



Fore-wing like diana, Riff., with a broad transverse band like 

 melpomene and a red basal patch. Within the cell is a well-defined 

 yellow squarish spot. Hind-wing black with red basal streak. 



Habitat. French Guiana, St. Jean de Maroni. 



Type in coll. Joicey. 



Except for the red base to fore- and hind-wing, this form 

 is similar to primus. 



Four specimens have a clear yellow spot of varying size, 

 without any dark suffusion. Fourteen show more or less 

 black suffusion, and nine have only a rudimentary yellowish 

 mark within the cell. 



Heliconius melpomene cybele ab. negroida, nov. 



(Plate CVII, fig. 2.) 



Fore-wing red at base, with a prominent wedge of black pointing 

 to base and occupying more than half the cell. Beyond the cell 

 is a half band of long yellow spots heavily suffused with black 

 from costa to vein 4; externally this half band is edged with red 

 of the same colour as the base. Between veins 3 and 4 is patch of 

 yellowish scales mixed with black and edged with a small mark of 

 red. Hind-wing black, with a red streak at base considerably 

 suffused with black scaling.

Fore-wing with the basal area black, but with a very short in- 

 conspicuous yellowish streak. A red transverse band almost as 

 wide and of similar pattern as in typical melpomene. Lying wholly 

 within the cell is a large squarish yellow blotch, which is contiguous 

 with the red transverse band only at vein 2 ; above it is separated 

 by the dark ground-colour; on the costa is a small yellow mark 

 on edge of transverse red band. Hind-wing black, with the base
