0. psorica H.-S. (75 f) is in the greyish-brown, the body somewhat lighter and more yellowish; 
on the forewing the median area is edged by 2 darker lines which are bordered with lighter on the averted sides, 
the distal line projecting twice distally in an acute angle; in each of the two cell-angles there is one.black dot; 
the darker subterminal line being parallel to the distal margin is distally round waved between the veins and 
towards the distal margin bordered with a lighter colour. Type from Venezuela. The small whitish $ with 
narrow wings and a very large anal tuft, being figured by Herrich-Schaffer, certainly does not belong to 
this species, but is probably much rather a Tolype. 
11. Genus: Macromphalia Fldr. 
Evidently very closely allied to the preceding genus, but at once discernible by the separate origins 
of veins 7 and 8 of the hindwing. The rudimentary palpi are somewhat drooping. They are, moreover, robust 
insects with broad wings, the with a relatively short abdomen, the $ without an anal tuft; $ antennae very 
long, with long pectinations. Costal margin of hindwing straight or somewhat concave. The range of most 
of the species extends into the southernmost parts of South America to Chile. Most of the Chilian species are 
very variable and seem to me to belong to but very few species. Examinations of the genitals are here absolutely 
necessary in order to ascertain which is a species and which a form. 
Type: M. chilensis Fldr. 
M. lignosa Wlcr. (75 f) is a very doubtful insect; according to Schaus, there is in the Coll. Dognin 
as lignosa a Macromphalia which looks very much like the following and differs in the broader median area 
with a less dentate distal border which is bordered with broader and purer white; subterminal area not lighter, 
without the small black spots therein. From the common point of view, however, lignosa is an Euglyphis of 
the narceta- group (cf. there!). Argentina, Chile. 
M. chilensis Fldr. (75 f). Body and wings greyish-brown; mesothorax and base of abdomen darker; 
forewing with a darker median band, its dark border-lines on the averted sides lighter, the distal one projecting 
thrice distally acute-angled; postmedian area somewhat lighter, then follows a still lighter subterminal band 
on the outside of which there are small black internerval spots; in the darker marginal area the veins are some¬ 
what lighter. Chile (Valdivia). — Larva greyish-brown with a double row of long black pencil-like brushes; 
head black with a yellow V-shaped marking. Ventral feet and claspers reddish. 
M. rubrogrisea Phil. (= rustica Phil.) (75 f) is very similar, but the median area is broader, occa¬ 
sionally prominently darker, the light subterminal band is absent, the row of the small dark antemarginal spots 
is more coherent, the distal border of the median area is not so pointedly notched, between the veins roundish 
convex. Chile. 
M. vaidiviensis Dogn. (75 f) has a somewhat lighter reddish-brown forewing with a dark brown 
median band which is twice as broad at the costal margin as at the hind-margin, enclosing a small black discal 
spot, and on both sides bordered with light, the distal border projecting still more flatly than in the two preceding 
species; fringes on the ends of the veins crossed by a somewhat lighter colour. Described from 1 $ from Valdivia. 
M. rivularis Btlr. (= dedecora Phil, nec Feisth.) (75 g). The <$ is above greyer than the preceding 
species, the border of the median area is almost white, shaped as in vaidiviensis, with a sub marginal double 
row of small whitish lunae; the black median spot is strong. The $ is lighter, yellowish-white, the border of 
the median area represented by brown double lines, in the subterminal area before the black antemarginal 
lunae with a greyish-brown notched nebulous band; costal area in the centre and subapically darkened with 
brown. Chile. 
M. dedecora Feisth. ( = ancilla Phil.) (75 g) is on the forewing greyish-brown, at the apex somewhat 
lighter, with 3 waved blackish-brown transverse lines and a black discal dot. Hindwing darker, with a whitish 
median band and darker subterminal band. Chile. — The larva is clothed with brown hair, with a double row 
of long black, pencil-shaped hair-tufts along the dorsum. Cocoon similar to that of C. potatoria. It lives on 
Pinus and Miihlenbeckia. 
M. purissima Btlr. (75 g) is snow-white, in the basal half of the forewing, on the hindwing and body 
with a silky gloss; the median area of the forewing is edged by 2 brown lines, the proximal one consisting only 
of a costal-marginal streak, the distal one at the costal margin black and notched; a submarginal indistinct row 
of small black lunae, at the costal margin before them an oblong black spot, at the cell-end a black spot. 
Hindwing with a brown hair-pencil at the cell-end. The $ is more yellowish, with much fainter markings, the 
submarginal lunae combined as a fine brown line; hindwings with brown anal spots. Chde. 
M. hypoleuca Phil. (75 g) resembles rivularis , but it is lighter, the $ quite yellowish-white, the lines 
as fine as hairs, not double, but single. Hindwing without markings. Chile. 
M. affinis Feisth. (75 g) resembles purissima, but in the $ the wings are chalky white, scantily strewn 
with brown, producing a grey impression. Lines arranged as in all the allied species. Chile (Valparaiso).
