Ph. bicolor Mschlr. (= costidentata Dgn.) (68 a). Hindwing as in the preceding, in the forewing the 
black discal band is absent, the broad black costa projects in its place only with a tooth. Hind-margin yellow. 
Guiana. 
Ph. amazonica Drc. (= brunnea Warr.) (68 b). Forewing blackish-brown, with a pale yellow triangular 
basal spot and a similar large subapical spot, hindwing deeper yellow, costa and distal margin bordered with 
black. Amazonas, Venezuela. 
Ph. hazara Btlr. (68 b) varies in the marking and colouring, being red-brown and yellow in the 
forewing, the distal margin and hind-margin and a narrow part of the costa being black, as well as broad streaks 
on the analis and radius in the cells 2 and 3, and an anteriorly open horse-shoe at the end of the discoidal 
cell. Hindwing blackish-brown with a more or less extended light longitudinal stripe behind the discal cell. — 
The form heliconides Prt. has an entirely black apical area without a light subapical band. Brazil, Peru. The 
model of the species is Stalachtis calliope, L. (vol. V, pi. 143 b); it otherwise makes entirely the impression of 
a Pericopis (Chetone ) and has originally also been described as such. 
Ph. integra Fldr. (68 a). Red-brown, distal margin on both wings broad, costa of forewing narrowly 
black. Costa of hindwing and a discal band of forewing pale yellow, fringes at the apex of forewing white. 
Brazil. 
2. Genus: Myonia Wkr. 
Distinguished from the preceding genus by the 1st cubital vein in the hindwing rising with the 3rd 
median from the same place or forked; if this is not the case, at least the antennae of the $ are only ciliated. 
1. H i lr d wing chiefly yellow or- white, wings nowheres hyaline (Dialephtis Fldr.). 
M. salvini Fldr. (68 b). Yellow, with blackish-brown margins of the wings (except the hind-margin 
of the hindwing). Subcosta of forewing yellow. Guatemala; Colombia. 
M. semimarginata Dgn. Like salvini, but the hind-margin of the forewing is not black, the black 
distal-marginal band of the lrindwing is broader. Colombia. 
M. bicurvata Bastelb. (68 b) is like salvini, the costal margin of the forewing is straighter, the black 
distal margins of both wings broader, that of the forewing extending to the cell. Peru, Colombia. 
M. josia Fldr. (68 b). Forewing blackish-brown, with a yellow large basal spot behind the cell, and a 
yellow transverse band not reaching to the hind-margin. Hindwing yellow, distal margin and hind-margin 
black as well as a basal stripe in the cell and one behind it. Costal margin yellow. Brazil. 
M. maeropoeeiia sp. n. (68 c). Size and hindwing as in josia, but the hind-margin narrower black. 
In the forewing the yellow basal triangle fills up a large part of the cell, the discal spot is very broad (5 mm). 
Peru. $-type from the Chanchamayo in the Berlin Museum. 
M. pyraloides Wkr. (68 c) is like josia, mostly larger, in the hindwing the hind-margin is broader and 
the costal margin coherently black, only the extreme costa yellow as far as the subcostal cell. — In the form 
longiplaga Warr. the postdiscal band of the forewing is not broad at the costal margin either, but rounded off. 
Colombia, Brazil. 
M. dominula Warr. resembles the preceding. The hind-margin of the forewing finely yellow, in the 
hindwing the hind-margin and fringes are yellow; in the anal part a stripe of black scales. The yellow centre 
is beneath twice as broad as above. •— Expanse of w r ings; 35 mm. Argentina, Uruguay. 
M. alea Drc. Forewing pale yellow; apex, distal margin and hind-margin bread black, a black 
costal streak from the base to about y 2 of the wing. Hindwing yellow, with a black marginal band at the costal 
margin, apex and distal margin as far as the tornus. Expanse 31 mm. Ecuador. 
M. priverna Cr. = privigna Hbn.) (68 b). Forewing brown, veins at the base (particularly in Brazilian 
specimens) paler, a whitish-yellow postdiscal band from the costa to the 2nd cubital vein; in the B it- is mostly 
straighter and more robust, in the $ thinner, more bent, posteriorly very narrow. Hindwing yellow with a 
black distal margin, in the $ often also a stripe below the costal margin and sometimes even the hind-margin 
blackish. Beneath in the forewing a yellow spot at the hind-margin, which may reach in front to the radius 
and distally to 4 / 5 of the analis. — In the form fulva Warr. the blackish-brown markings are stated to be merely 
brown on both wings, in the forewing the whitish band above only extends to vein 5, beneath to 3, it puts forth 
a pointed tooth proximally at the cross-vein. Guiana, Brazil. 
M. quadriguttata sp. n. (68 b) has a habitus similar to the Polypoetes. Forewing black, veins red-brown, 
a large yellow spot distally to the transverse vein, some yellowish dusting behind the cell. Beneath the yellow 
spot is broader, almost reaching the costal margin, a yellow hindmarginal spot behind the centre of the cell. 
Hindwing black with a yellow discal spot which is continued to the hind-margin in yellow dusting, beneath 
yellow, distal margin and basal spot in the cell black. Peru. $ type from Moxos in the Berlin Museum. 
M. quadricolor Wkr. (68 c). Forewing brown, with light vein-streaks at the base and a club-shaped 
light basal stripe on the axillaris, a light postdiscal transverse band which is posteriorly shortened and yellow 
at the costal margin. Hindwing yellow, edged with black. Expanse 27 mm. Amazons.
