P. miilleri sp. n. (78 s) is a large species with relatively very broad wings, of a dark, more greyish- 
brown colour, strewn with yellowish-grey, the darkest in the median area, in the subterminal area more reddish- 
brown, at the distal margin strewn with violettish-grey, but all the colours not very much contrasting; subbasal 
band broad, shadow-like blackish and extending to below the cell, median area moderately broad, at the costal 
margin about twice as broad as at the hind-margin, the border-lines hardly waved, the white discal dot tiny, 
close in front of the median area; the border-line between the postmedian and subterminal areas faint, blackish, 
distally bordered with a lighter colour, below the costal margin feebly though distinctly undulatingly dentate. 
The subterminal row of black spots is complete, arranged as in prosper ; the blackish discal shadow is faint but 
broad, extending from the subbasal line to the subterminal line. Hindwing very dark, deeply coppery blackish- 
brown, with 3 lighter transverse bands: an antemedian, a postmedian, and a marginal one; the hind-margin 
exhibits hair of the same colour. Penis similar to that of conradti, but on the whole much stouter, shorter and 
broader, the main spine being shorter with a much broader base, the accessory spine rising higher, so that both 
apices are situate in the same height; the 11th tergit is quite different from conradti , but the differences 
of the penis are sufficient for the characterisation. According to several $$ from Chiapas (Mexico), taken 
in June, named in honour of Robert Muller in Mexico; type in the Coll. Draudt. — guatemalteca /. n. (78 e) 
is evidently a form of it. much lighter and more contrastingly coloured, particularly the whole marginal third 
conspicuously light; the intensely blackish-brown darkened median area is much broader, inside undulatingly, 
outside almost rectilinearly defined, with an obtuse angle on 7, the white discal dot stronger, situate within 
the median area, the black discal longitudinal patch sharply defined, only between 5 and 6, the postmedian 
border-line more distinct ; hindwing also much lighter. According to a faultless $ from Guatemala in the Coll. 
Bang-Haas. 
P. granula Schs. (= hempsteadi Schs.) (77 d, 86 a) is allied to conradti, but larger, with still broader 
wings, the median area broader, more blackish-brown, at the costal margin 1 cm broad, at the hind-margin 
only y 3 cm broad, the proximal border below the costal margin distally angular, the distal border hardly dentate, 
on the uppermost radial branch distally angular, from there extending in a flat, inwardly concave bow to the 
hind-margin; the discal longitudinal patch is distinctly defined, blackish, more distinct than in the two preceding 
species; the small subterminal spots are distinctly ochreous, either all. or only the anal ones, spotted black. 
Guatemala. This species was regarded by Schaus as a synonym to conradti, but according to what has been 
said at that species, this is probably not the case. The species varies besides in the lighter or darker, 
more yellowish or reddish ground-colour and in the width of the median area. 
P. crossaea Drc. (77 e) of which likewise only the type is known, which is besides so much damaged 
that but few details are yet to be recognised, is presumably also allied to conradti, but very much lighter, quite 
unicoloured light reddish-brown, behind the median area still lighter, the markings very indistinct, anally 
with two small black spots arranged as in conradti, farther above there are some more punctiform ones. The 
specimen is somewhat smaller, the apex of the forewing somewhat rounder, the distal margin more convex. 
Mr. Tams kindly sent a photo of the type and a microphotographic reproduction of the genital organ; accordingly, 
the penis on the whole exhibits a much broader and shorter, almost flat wing-like shape and is not so deep dark 
brown chitinised, the vesical edge of the terminal spine shows in its upper half 2 smaller accessory spines, each 
of which is again provided with a still smaller accessory spine, so that this edge looks like a short blade 
of a saw; the opposite edge shows below the centre an intensely chitinised hunched projection. Balnaos, 
Jalisco (Mexico). 
P. lemoulti Schs. (77 e) forms a transition from conradti to nox ; a very large species with narrower 
wings; forewing dark brown, thorax and hind-margin of forewing hued with grey, before the centre with 2 
yellowish-red dentate lines, convergent to the hind-margin, also 2 postmedian finely waved lines which are 
dentate towards the costal margin; the light brown irregular subterminal row of spots exhibits the usual black 
centres. French Guiana. — yahuarta Dogn. (77 e) is somewhat smaller; the author considers it to be a local 
race of the preceding species. Peru (Yahuarmayo). 
P. negrita Dogn. (78 c) is still somewhat smaller, on the dark yellowish-brown forewing the ante- 
median area, the transverse lines, and the subterminal area are lighter, the first line at the hind-margin farther 
from the base than at the costal margin; the small light subterminal spots with but one black anal dot. Hindwing 
coloured like forewing, with reddish-brown fringes. From the Rio Negro (East Colombia). Separable from 
antonia by waved transverse lines. 
P. nox (= melana Dogn.) (78 c) is very similar to the preceding species, large and strong, but much 
darker, with almost black hindwings and marginal area of the forewing; lines arranged exactly as in lemoulti. 
The type of nox, from the Coll. Staudlnger, is not separable from melana. only the transverse lines are 
more indistinct owing to the insect having flown very much, but on examining the insect very carefully they 
show the very same course, the white discal dot being also present. A § from the Berlin Museum is very large, 
with yellowish veins, all the subterminal spots very conspicuously rusty yellow. Panama to Colombia and 
Brazil. The penis exhibits a great resemblance to that of conradti and especially of mulleri.
