88 Messrs. J. J. Joicey and W. J. Kaye on new 
in the melpomene form. Thus, without the yellow band the 
erato form becomes erythrea as known from French Guiana 
and the Lower Amazon, and the melpomene form similarly 
becomes tyche from the same regions, Yet these two, while 
probably sufficiently alike on the wing, are obviously different. 
Heliconius numata numata, ab. melanopors, J. & K. 
(Trans. Ent. Soe. 1916). 
Fore wing above sienna-brown and black. Inner margin 
broadly black. Basal half of wing dark sienna-brown, with 
a large black wedge-shaped mark within the cell directed 
towards base. A large black discoidal patch and two smaller 
patches above and below vein 3 close to cell. Transverse 
band of the same colour as the basal area, but slightly paler. 
Three subapical spots also of the same colour, and an indica- 
tion of similar marginal dots. Hind wing above similarly 
coloured to fore wing. The wffole ofthe outer marginal half 
of wing black, forming a convex area on its upper edge. A 
rather small! brown spot at apex within the black area.

This is a parallel form to melanops, but of the colouring 
of mavors. ‘he occurrence in French Guiana of both these 
forms is of great interest, as the theory at once suggests. 
itself that possibly arcuella (a subspecies of aristiona) and 
with it all the forms usually associated with aristzona are all 
conspecific with numata: The drawings by our friend 
Dr. Eltringham of the genital clasps of nwmata torms (Trans. 
Ent. Soc. 1916, pl. xin. figs. 4-6) and aristiona forms (id. 
pl. xiv. figs. 3-9) are sufficiently close to offer no difficulty to 
such a possibility. 
Heliconius numata talboti, J. & K., subsp. n. 
Fore wing above with the basal area dark ochreous. Costa 
black. A large round black blotch within the cell and a 
wedve-shaped black mark running to base. A very slender 
curved black streak along vein 1. A narrow, yellow, trans- 
verse, irregular band from within the cell to vein 2, stopping 
some distance short of tornus and embracing a large roundish 
black blotch between veins 2, 3. A black blotch above this 
s almost merged in the black ground-colour of the apical 
half of the wing. An indication of a yellow transverse 
band from costa beyond cell to meet the first band at vein 2. 
Two or three yellow subapical patches much suffused with 
black. A trace of a row of yellowish marginal] dots. 
Hind wing above dark ochreous, with a tinge of yellowish
