D. panamensis Schs. Head and base of abdomen reddish-brown, thorax lilac grey; abdomen above 
orange with black bands. Forewing purple grey with a curved lilac whitish antemedian shadow and a similar 
feebly curved postmedian shadow; at the oblique cross-vein a fine black line; marginal area lilac white, at the 
apex and anal angle very narrow. Hindwing lilac whitish, at the base with light reddish hair, with a broad 
purple grey subterminal shadow. Expanse of wings: 98 mm. Described from a $ from Panama. 
D. fassli Dogn. (117Bd) is very similar to panamensis ; thorax red-brown, head and collar lighter 
reddish; abdomen above black, base, ventrum and anus rusty brown. Fore wing lilac whitish, a small oblique 
basal area and the median area brownish with an oval brownish small discal spot; postmedian line feebly 
S-curved, inwards broadly dusted with lilac white like the marginal area behind the feebly curved broad 
brownish subterminal shadow. Abdomen whitish, feebly dusted with brownish, with an extinct discal spot 
and 2 very indistinct anteterminal shadows. Colombia, Bolivia. 
X. arpi-group. * 
D. arpi Schs. (= satanas Jones) (119 a). A beautiful large, quite isolated species, most peculiarly 
marked. Fore wing blackish-brown, cell-end filled with black; antemedian line irregular, projecting far in the 
cell, below it interrupted and continued to the base. Postmedian line receding almost to the cell in a long bow 
below 4 and 6, projecting towards the margin in 2 bows between 2 and 4, outside light, filled with almost 
white. Hindwing with a broad brownish ochreous median band which is generally very dark, in — seitzi /. n. 
(119 a) bright orange, in - zikani f.n. greyish-white. The larger $ is more monotonous, behind the post¬ 
median line fawn-coloured, the band of the hindwing much narrower, nearer to the margin, between 2 and 3 
notched. Hindwing beneath covered with long stiff vertical hair as in the genus Megathymus. The larva is 
opal-white or cinnamon-red with a black X-shaped dorsal marking and white spines, with black tips. It lives 
on Rapanea flocculosa and Eucalyptus; in the day-time it hides on the trunk and pupates in a web between 
jeaves. Southern Brazil. 
(?) Dirphia lauta Berg lias remained unknown to me. According to the description it is a small insect the forewing 
of which is only 27 mm long. Body covered with long ochreous hair, intermixed with greyish-white hair, head and thorax 
more rusty red, abdominal segments with somewhat darker rings. Wings very scantily scaled, dingy white without markings, 
costal margin beneath as well as the legs yellow. Rio Negro (Argentina). I doubt whether it is a Saturnid at all. Mr Kohler 
had the kindness to search for the type, but it could not be discovered. 
Nothing could be found out about the „Dirphiu“ nubila, satellitia, purpurascens, undulosa described by Walker, from 
the Coll. Fry : the types seem to have been lost and the descriptions are quite insufficient. Part of them may be Syssphingidae. 
16. Genus: Catocephala Blch. 
This genus comprises a small group of rather closely allied species, mostly from the southernmost parts 
of America, distinguished by the veins 6 and 7 of both wings arising from one and the same place or on a 
short stalk; the variability, however, is here also rather great in individual specimens. Shape of wings generally 
somewhat narrower, especially in the Thorax loosely haired, intermixed with long, partly oar-shaped hairs. 
Abdomen of the dd projecting but little beyond the hindwing, in the $$ more so. Antennae of the dd with 
long pectinations, in the $$ shortly serrate-dentate with short spiny bristles. All of the species are very variable; 
Bouvier has written a short monography on them which, however, does not state all the differences which 
occur in large series. 
Type: amphinome F. 
I. Group: abdomen above with spatulate hairs ( Catocephala ). 
C. amphinome F. ( = humeralis Wkr., hyadesi Mob.). Forewing cinnamon red-brown with 2 notched 
transverse lines inwards edged with a very faint whitish colour, between them a large yellow discal spot which 
is outside thrice notched; subterminal line indistinct. Hindwing with 2 blackish transverse lines, feebly 
notched and bent on 5. Abdomen above black with narrow yellow segmental margins, a rusty yellow base and 
anus. Southernmost Chile and Fuegia. 
C. rufosignata Blch. is allied to the preceding species and distinguished by the dark cinnamon red 
colour, more sharply notched transverse lines without any white, with a white instead of yellow cellular spot. 
Southern Chile. 
C. marginata Phil. (117 Bd) is likewise very similar to rufosignata , lighter, the Jf more greyish-red, 
the two transverse lines less notched, on the inverted sides broadly edged with whitish; cellular spot in the 
centre white, then yellow and outside edged somewhat blackish; subterminal line much stronger, blackish, 
strongly and irregularly notched, and outside bordered with whitish. Hindwing with 2 broad blackish transverse 
bands which are much less curved than in the preceding species. Abdomen in both sexes above almost entirely 
black, only narrowly bordered with yellow. Chile. 
C. patagonica Bouv., only recently described, was not before me. Size of amphinome and its allies. 
Body light brownish yellow, hairs of patagia with whitish tips, abdomen somewhat more yellow, very scantily
