the 1st and 2nd median branches. Beneath, the same, except that there is (in some 
examples) a row of four white spots along the outer margin. 
Hind wing precisely as in T. Harmonia, namely, tawny-orange, with a broad stripe 
along the fore margin not reaching the costa or the apex, an outer border, widening 
towards the anal angle, and a central stripe from the abdominal edge to the lower radial, 
crossing part of the cell, black. Beneath, the same, except that there is I row of fourteen 
silvery-white submarginal spots. 
Common on the banks of the Cupari (branch of the Tapajos), where it replaces 
T. Harmonia, of which it is a tolerably well-marked local variety. I found it only in the 
district just named; whilst T. Harmonia ranges, under its typieal form, over a wide tract 
of country, from Surinam, Para, and the Tocantins to the banks of the Upper Amazons.

This species is common throughout the Amazon region, in company with H. Numata, 
Melincea Egina, Mechanitis JPolymnia, and other species of Hel'iconida. I have found 
examples which almost link it to H. Numata; indeed the three forms //. Num«(a, 
H. Sylvana, and H Bucoma might be treated as so many varieties of one stock, being in 
an incomplete state of segregation.

This species is so variable that it is difficult to find two examples exactly alike. 
Cramer's figure represents a frequent aberration, in which the central stripe of the hind 
wing is connected by dark lines with the hind border ; in the markings of the fore wmgs, 
however, it exhibits nearly the most common form of the species. It differs from II 
Sylvana in the following points : t> 
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 
number and widely separated. .... 
2. The black spot in the middle of the fore-wing cell is connected with a hne of the 
same colour, which runs to the base.
