88 Messrs. J. J. Jolcey and W. J. Kaye on new 



in tlie melpomene form. IMius, witliout tlie yellow band tlie 

 ei-ato form becomes erythrcen as known from Frencb Guiana 

 and the Lower Amazon, and the ineJpomene form similarly 

 becomes tijche from th.e sam.e regions. Yet these two, while 

 probably sufficiently alike on the wing, are obviously different. 



Ileltconius numata numnfa, ab. meJanojyors, J. & K. 

 (Trans. Ent. Soc. 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 o£ 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 whole of the 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. 



Hab. French Guiana, Nouveau Cliantier. 



This is a parallel form to melanops, but of the colouring 

 of niavors. The occunence in French Guiana of both these 

 foims is of great interest, as the theory at once suggests 

 itself that possibly arcuella (a subspecies of aristiova) and 

 with it all the forms usually associated with aristiona are all 

 conspecific with numata. The drawings by our friend 

 Dr. Kltringham of the genital clasps of numata forms (Trans. 

 Ent. Soc. 1916, pi, xiii. figs. 4-6) and aristiona forms (id. 

 pi. xiv. figs. 3-9) are sufficiently close to offer no difficulty to 

 such a possibility. 



Heliconius numata talhoti, J. k K., subsp. n. 



Fore wing above with the basal area dark ochreous. Costa 

 black. A large round black blotch within the cell and a 

 wedge-shaped black mark running to base. A very slender 

 cuived black streak along vein 1. A narrow, yellow, trans- 

 verse, irregular band from within the cell to vein 2, stopping 

 some distance short of tornusand embracing a large rountlish 

 black blotch between veins 2, 3. A black blotch above this 

 is 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 baud at vein 2. 

 Two or three yellow subapical patches much suflfused with 

 black. A trace of a row of yellowish marginal dots. 



Hind wing above dark ochreous. with a tinge of yellowish
