726 CALOSATURNIA; POLYTHYSANA. By Dr. M. Dbaudt. 
A. galbina Clem. (103 d). Rather scantily scaled, brownish grey with 2 broad not quite distinct transverse 
lines and very faint traces of a somewhat undulate subterminal line; eyespot from outside inwards: black, yellow, 
black with a hyaline central streak; in the apex a black spot distally bordered with white, then with red; distal 
margin bone-white, outside passing over into the grey ground-colour. Hindwing the same, but the basal area 
lighter. We figure an aberrative <$ in which the median area is broadly interrupted by the widened white 
transverse stripes: — interrupta ab. nov. (103 d as galbina). Arizona and Northern Mexico. anona Ottolengui 
on the whole is a darker local race from Texas; especially the basal and median areas of the forewing are more 
blackish with more distinctly prominent white transverse bands and markings; the costal area of the hindwing 
is likewise darker scaled with a dark subbasal demi-band. The Mexican race (from Chihuahua) has been 
separated as dyari Ckll. and is characterized by lighter hindwings. Larva on Grease wood, the young larva 
has been described to be black with long fawn-coloured hair. 
A. honiogena Dyar. (103 d) is larger, more densely dusted, with a darker ground-colour, the veins 
distinctly marked light yellowish ochreous, the inner transverse line yellow, pointedly produced distally on the 
median vein, the outer line almost straight, narrow, white; costal margin and the outermost border of the bone- 
white marginal area ochreous; ocellus as in galbina, but besides with a light blue crescent in the proximal half 
between yellow and black. Hindwing lighter, only with the distal transverse stripe. Mexico, also found in 
Arizona. 
5. Genus; Calosatmrnia 8m. 
Anatomically hardly separable from Agapema or Eudia, at most somewhat smaller and more slender, 
the antennae a little shorter and somewhat shorter pectinated. In the neuration no essential difference. 
Biologically different by the larvae the thorns of which produce a burning sensation. Only 1 species: 
C. mendocino Behrens (103 d). Forewing red-brown, only with the discal ocellus, without distinct 
transverse stripes. Hindwing orange with a broad black subterminal band and discal eyespot. Northern 
California. The eggs are deposited in numbers of 1 TO pieces on leaves of “Manzanita“ (Arctostaphylos 
tomentosa). Larva green or reddish-brown, with severely burning thorns. 
6. Genus: I*olytJiysana Wkr. 
Very similarly structured as Automeris, but palpi short, apex of forewing somewhat produced though 
rounded. On the forewing 3 rises somewhat nearer to 4, 6 on a short stalk with 7 and 8. On the hindwing the 
cell is longer, occupying almost % of the length of the wing; otherwise neuration almost the same. The male 
imagines fly at noon in the sunshine around the tops of trees and are difficult to capture. The larvae exhibit 
magnificent spots on the 2nd and 3rd rings, 8 bicuspid thorns on the 3 first rings, 4 star-shaped tufts of spikes 
on each of the 6th to 11th rings, 3 of them on each of the 12th and 13th rings. They pupate in a pear-shaped 
cocoon which is open at one end. They all live in Chile. 
Type: P. rubrescens Blch. 
P. rubrescens Blch. (= andromeda $ M. A- IT., rhodocera Prittw.) (104 c) is a very common species 
and of a rather variable colouring and marking. Forewing yellowish-grey with a large dark basal inner-marginal 
spot, 2 transverse bands the distal one of which projects between 2 and 4 with round projections almost to 
the margin and a somewhat oval eyespot between them. Hindwing dark orange, suffused with crimson in a 
variable extent, and with a carmine, white-centred ocellus and 2 narrow darker transverse bands. Common, 
but difficult to capture. The fly i n the sunshine round the tops of trees between 12.30 and 2 p. m.; the 
^ flies at night. Chile. 
P. andromeda Phil. (104 c) is externally very much like rubrescens, but easily discernible by the circular, 
not oval, ocellus on the forewing and the absence of the basal transverse line on the hindwing. The latter is 
reversely coloured, red, instead of orange in rubrescens, and orange, instead of red in rubrescens, the apex of the 
forewing is somewhat less produced than in rubrescens. Antennae light red-brown, not black. Chile. 
P. edmondsii Btlr. (= andromeda M.& IT.) is very similar to andromeda, but the distal border of 
the distal transverse band is of a purer white; hind wing carmine, in the inner-marginal half of the disc and at 
the distal margin orange, the margin brown. The $ is lighter, more flesh-coloured, the disc outside olive brown. 
Common in March and April, the flies in the sunshine between 9.30 and 11 a. m. The stout grey larva with 
hair-pencils lives on roses and pupates in a widely meshed whitish silk-web. Chile. 
P. cinerascens Phil. (= apollina Fl.dr., albescens Btlr.) (104 b) is easily discernible from the preceding 
species by the quite different duller yellowish-grey colouring without red, sometimes almost white. Scheme 
of markings otherwise the same. The rarest of the 4 species, flying between 9.30 and 11a. m. Larva beneath
