OF THE AMAZON VALLEY. 553 



the 1st and 2n(l nuMlian Ijranehes. Beiieath, the same, exeept that there is (in some 

 examples) a row of lour white spots along the outer margin. 



Uiud iciiiff precisely as in T. ILirmonia, namely, tawny-orange, w it h a l)r()a(l stripe 

 along the fore margin not reaching the costa or the apex, an outer l)order, \\id(>ning 

 towards the anal angle, and a central stripe from the ahdominal edge to the lower radial, 

 crossing part of the cell, black. Beneath, the same, except that there is a row of fourteen 

 silvery -white submarginal spots. 



Common on the hanks of the Cui)ari (branch of the Tapajos), where it re])laees 

 T. Ilarmonht, of which it is a tolerably well-marked local variety. I found it only in the 

 district just named ; whilst T. Jlormonio ranges, imder its typical form, over a wide tract 

 of country, from Surinam, I'ani, and the Tocantins to the baiiks of the Upper Amazons.

1. IIklicokils Syiaaxa, Cranun-. 



Papilhi Sylvona, Cramer, Pap. Exot. t. .ifil. f. C, D. 



This species is common throughout tlu^ Amazon region, in company with H. Nv.mdht, 

 JIeli//(ea Egii/a, JLechoiilis Fohimn'ui, and other si)ecies of IIcli('0)iid(P. I have found 

 examples which almost link it to 11. Xnmata; indeed the three forms II. NiDiidhi, 

 II. Sylvana, and II. Eiicoma might be treated as so many varieties of one stock, being in 

 an incomplete state of segregation. 



2. IIkliconii.s Ni'MATA, Cramer. 



PapUhi Niiiiuita, Cram. Pap. Exot. t. 297. f- C, D. 



This species is so varial)le that it is dilTicult to find two exam))les exactly alike. 

 Cramer's figure represents a fre(|uent aberration, in which the central stripe of the hind 

 winu' is connected by dark lines with the hind border; in the markings of the fore wings, 

 liowever, it exhibits nearly the most common form of the species. It difiers from IF. 

 Si/lruiid in the following points : — 



1. The yellow crossbelt of the fore wing lies wholly beyond the cell; the black apical 

 part is much smaller; and there is only one transverse row of spots, which are three in 

 luimber and widely separated. 



2. The black spot in the middle of the fore-wing cell is connect(Ml witli a line of tlie 

 same colour, which runs to tlie base. 



* Syiioiiviuoiis witii our Acni'oid lIclicoiii</a;,[).M)('<. The small iicrvulf iiicutioncd (in tlu- iidte on that page) as 

 one of the ilistinguishiiij; cliaracters oC the Dannoid Ileliconidte, was considered Ijy Doulileday (who noticed it in tlie 

 Danaidw projier) to he the internal nervurc. It is connected with the suhmedian ncrvnre, and not the mediim. as 

 stated by inadvertence. 



t I'r. Feldcr jjroposes this innovation of the masculine for the feminine termination, on the grounds that the name 

 Heliconia clashes with that of a grou[> of [dants ijihabiting the same region, and that Limiicus first used the word in 

 the masculine form, Pupiliones Ilcliconii.
