Ph. subaurata Warr. (= aeretincta Warr.) (6 a). Nearly related to taediata, but generally with a suffusion subaurala. 
of golden-bronzy over a great part of the upper surface and of brigther ochreous on the under. In very fresh 
specimens, however, this tone is not, or scarcely observable, but in any case subaurata is distinguishable by 
the slightly longer hindtibial process (Y 2 first tarsal joint), rather more falcate forewing, with cell-dot more 
conspicuous and postmedian line better defined and rather more distally placed, and more rounded hindwing. 
Underside of hindwing with a dark spot at abdominal margin (behind the diseocellulars), characteristic of 
many of the following species, but beginning to show in taediata. Both Warren’s types were from Carabaya, 
S. E. Peru. 
Ph. assa Druce (5 g). Smaller than subaurata', apex of forewing less produced, hindtibial process longer, assa. 
reaching considerably beyond middle of 1st tarsal joint. Face with upper 3 / g golden. Underside suffused with 
rather dark olive-grey, with narrow whitish distal borders, the forewing posteriorly and the hindwing anteriorly 
also remaining whitish, the postmedian line indicated in whitish. Costa Rica: Rio Suzio, only the type A known. 
Ph. mitigata Prout (5 g) combines the shape of forewing and whitish fringes of taediata with the bent mitigata. 
hindwing of the following group. 2nd joint of palpus, in the $ the 3rd also, strongly elongate. Hindtibial 
process about as long as in assa. Lines even weaker than in most taediata', cell-dot of hind- larger than that of 
forewing and ringed with pale scales. Underside with blackish spot between cell-dot and hindmargin of hind¬ 
wing strong. Described from Panama, subsequently received from Costa Rica. 
Ph. leuconyssa sp. n. A very close relative, possibly even a race, of mitigata (5 d). Palpus strongly leuconyssa. 
reddened (in mitigata whitish). Forewing rather narrower, yet with the costal margin rather well arched. Post- 
median line broad, clear white, not dark-shaded proximally, arising in the apex of the forewing, oblique and 
very faintly curved, reaching hindmargin at least as far out as in mitigata, on hindwing very slightly curved, 
ending at 3 / 5 abdominal margin, i. e. nearer to the dark spot of underside than to anal angle (in mitigata 
equidistant). Guatemala: Panajachel, 5000 feet (Champion). Type $ in Mus. Brit., recorded in the “Biologia” 
as ( Dichorda ) iris. 
Ph. albiceps Warr. (6 a) differs from mitigata in the white face, rather less produced apex of forewing, albiceps. 
more angled distal margin of hindwing and deeper green colouring, also structurally in the obsolescence of the 
terminal process of the $ hindtibia. S. E. Peru. Subsequently collected in E. Colombia by A. H. Fassl. 
Ph. agari Prout. <$, 33 mm. Closely like the largest examples of vivida (6 a) and pupillata (6 b), palpus agari. 
rather longer (1% times the diameter of the eye), antennal pectinations longer (4 times diameter of shaft), 
hindtibia very little dilated, without terminal process. Fcrewing with termen more oblique, slightly bent at 
3rd radial. Hindwing with abdominal margin very long, termen strongly bent at 3rd radial; the black patch 
between diseocellulars and abdominal margin wanting. Dominica. 
Ph. vivida Warr. (6 a). This species and pupillata are a puzzling pair of twins, or possibly a still more vivida. 
extensive group of very close allies, not yet separable in the $ (though I have observed slight differences in the 
length of the 3rd palpal joint which will ultimately furnish clues), and in the only constantly distinguishable 
by the hindtibia. In vivida this bears only an absolutely rudimentary terminal process. Perhaps on an average 
— ■ at least in some localities — vivida q has the hindwing less extremely long and narrow, with the angle at 
3rd radial less strong. The dark posterior spot of the hindwing beneath is occasionally — though rarely - 
obsolete in both species, but perhaps less rarely in pupillata than here. Very generally distributed from Mexico 
to Brazil, the type from Venezuela. 
Ph. pupillata Warr. (6 b). For the differentiation of this species from vivida see above; in pupillata pupillata. 
the tibial process of the <$ reaches about to the middle of the long 1st joint of the tarsus. — ab. submaculata submacu- 
Warr., founded on a damaged q from Colombia, has a broad blackish antemedian cloud on the hindwing beneath, 
reaching from the anterior branch of the cell-fold to the submedian fold. In N. W. Venezuela aberrations almost 
as extreme are somewhat prevalent, acuta is distributed, and often common, from Mexico to Brazil. The type 
was from British Guiana. 
Ph. marcida Warr. (5 g). Apex of forewing not produced and without a black dot; hindwing rounded, marcida. 
The pale lines not sharp, but shaded with darker green in the central area . The black cell-dots reproduced on 
the underside, which has the hindwing and hindmargin of forewing more whitish, the former with the spot 
behind end of cell and a broad terminal band distinct,, green. <$ tibial process short. Eonte Boa (type) and 
British Guiana. 
Ph. sordulenta Dogn. is much like marcida (5 g); perhaps a form of it, but has the posterior half or sordulenta. 
more of the fore wing and nearly the whole of the hindwing (except a distal border) suffused with brown, the 
underside with a rather noticeable white postmedian band. Amazons (loc. typ.) and French Guiana. 
Ph. scnescens Prout (5 g). In size and shape near marcida, in structure (short palpus and pectinations senescens. 
and long tibial process) nearer niveiceps (6 a). Lines of forewing also placed nearly as in niveiceps, but the
