NEW NYMPHALINE BUTTERFLIES. 197 



Underside with all the white spots enlarged as above ; the rufous- 

 brown basal patch of fore wings is much larger, extending to the 

 submedian vein ; hind wdngs more variegated with whitish, the zig- 

 zag median line blackish and very prominent, the discal ocelloid 

 spots distinct, the submarginal line also blackish and prominent. 



Habitat. — Metan, N. Argentina, 2500 ft. 



Di/)ia)nine isolda, sp. no v. 



(T . Nearest to D. auubis, Hew., but differs above chiefiy in the 

 bright blue stripe along the costa of the fore wings extending around 

 and beyond the large white subcostal spot, almost reaching the 

 a,pex ; the white area extends further above the median vein, and is 

 more quadrate in shape. The hind wings have a little black at the 

 base, and the black marginal border is broader and not marked with 

 white. 



Underside : Fore wings almost as in anubis, but the curved stripe 

 within the cell is white, not yellow-brown, and only its upper edge is 

 bordered with blue. On the hind wings there is no brown spot on the 

 costa ; the base of the wing is dark brown, edged with white ; the 

 marginal border is chocolate-brown internally and yellow-brown 

 externally, intersected by the usual metallic blue line and internal to 

 it by a line of white, shading to bluish near the anal angle. Expands 

 1-6 in. 



Habitat. — Medellin, Colombia. 



A rather distinct species, differing from all its allies in the 

 blue costal stripe of the fore wings extending to the upper 

 submarginal spot. 



Knnica mygdon'ia var. ouioa, subsp. nov. 



(^ . Slightly darker than typical mygdonia, the two small sub- 

 apical spots on fore wings above whiter and more sharply defined. 



? . The fore wings are crossed on both surfaces by a broad 

 quinquefid discal band of pure white, all its spots contiguous and of 

 nearly equal size ; otherwise as in mygdonia 5 . 



Habitat. — Guatemala (Puerto Barrios, December, 1912). 



In the female of typical mygdonia the discal band of the fore 

 wings consists of three small and widely separated white sjiots, 

 whilst in omoa the spots are five in number, very much larger, 

 and not separated. The very scarce females of Eunica are evi- 

 dently much more subject to local influences than the males, and 

 the following subspecies show an almost exactly parallel form of 

 variation. 



Eunica cinara var. vega, subs-p. nov. 

 3 . Differs from typical cinara from the Upper Amazon, Ecuador 

 and Peru only in the blue of the upper surface being more brilliant 

 and on the under surface in the pale spots below the middle of costa 

 and at the end of the cell of hind wings being more whitish.
