ATELLA. By H. Fruhstorfer. 
an isolated black spot within it, as well as faded border markings on the undersides; probably a dry-season 
form. According to Hagen not rare in light woods in November and December, and again from May to August. 
alexis. — alexis Sm.. (= miokensis Ribbe) in contrast to the former form has very narrow black borders and hi conse¬ 
quence also on the underside a much compressed brightly coloured border area. Bismark Archipeligo, New- 
decemia. Pommern, New-Mecklenburg, Nussa-Laut and Mioko. — decernia subsp. nov. (107 e) has a considerably extended 
black basal area, so that the median area is reduced to a narrow band, which almost disappears on the hind- 
wings. Underside as in alexis with reduced brightly colored border area. Garibari a small island of British 
fumosa. New-Guinea. -—- fumosa Sm. is considerably larger than decernia the black color still further increased, the 
outer border reaches to the cell of the forewings and leaves only the remains of a rudimentary yellow band, 
which are continued on the hindwings in the form of yellow spots. Undersides beautiful dark orange colour, 
cluentia. with violet distal area. Kiriwina. — cluentia Fruhst. differs from fumosa Sm. from Kiriwina, in that the discal 
bands are no longer rudimentary, but are again completely formed, but they are much narrower than in any 
other Cupha form from New-Guinea. The undersides are more obsolete in markings than fumosa, all the black 
fergussonia. spots much smaller. Fergusson Islands. — fergussotlia Fruhst. is an uncommonly pale aberration with very 
broad, medially more extended, light yellow central bands of the forewings, which on the hindwings remind 
one of wallacei Fldr. from Waigiu. In general resembles the figure of modestes Heiv., but the yellow subapical 
spots of the fore wings are wanting. Undersides dull yellow with faded purple and black markings. Probably 
a dry-season form of the former. Fergusson-Islands. Locality is questionable. 
prosope. C. prosope replaces modestes in Australia, prosope F. has narrower wings and a sharper apex; basal 
portion of all wings redbrown, the sharply defined border deep black, broadening towards the apex. Forewings 
with fairly large subapical spot and above it an indistinct but yellow point. Undersides with dark yellow basal 
region, which has an extensive red border. Next to this is a well marked and sharply angled yellow median band. 
The distal area without white submarginal spots and redbrown shaded band which particularly on the forewings 
hum bohlti. have only a few black dots. North Australia, at Cape York and Thursday Island. -— As humboldti Fruhst. a 
form is described with narrower yellow central bands, on the hindwings especially becoming apparantly smaller 
towards the anal angle. Undersides pale dull yellow, lighter than in turneri from Misol. Hindwings with four 
distinct and three obsolete black marks, which are larger than the corresponding ones in turneri. Humboldt- 
Bay, September, October. Type in the British Museum. 
C. melichrysos is the natural continuation of the madestes group on the Solomons. The forms belonging 
here are larger than the species belonging to the Papuan territory and the forewings crossed by an almost white 
band. The undersides repeat the markings of the prosope and wallacei races, but the submarginal black spots, 
even on the forewings are well developed and are enclosed in a pale redbrown area. Undersides of both wings 
with a beautiful pale yellow transverse band, which stands out from the redbrown surroundings and which 
narrows considerably on the hindwings. According to Ribbe the specimens vary very much in size and espe¬ 
cially the $$ are very large. The color of the bands is sometimes paler sometimes darker, which probably depends 
melichrysos. upon the locality, melichrysos Math, from the island Ugi, has a broad golden yellow band from the end of the 
tredecia. cell to the apex of the forewings, on the hindwings a central band which ends at the rear median vein. — tredecia 
Math. (107 f) from Treasury Island has a yellow transverse band, which is white diotally and which runs up to 
the costa of the forewings. According to Ribbe from Bourgainville, the Short-land Islands and Rubiana. -— As 
pallescens. pallescens Godm. and Salv. a $ from Guadalcanar is in my collection with especially broad, pale yellow, but 
distally not whitish median bands of the forewings, which are narrower on the hindwings than in tredecia. The 
Avhole tone of the hindwings is generally duskier brown, the submarginal spots dusted over with black and nearing 
disappearance. Home of type the island of Maleyte. 
woodfordi. C. woodfordi Math, is the most beautiful and largest of the known species. Uppersides brown grey 
with broad black apical area and white oblique bands on the forewings which do not quite reach to the costa. 
The hindwings are crossed by a redbrown median band, in which long black intranerval streaks are situated. 
Violet wavy lines traverse the border area. Undersides'with greenish grey basal area and towards the anal 
angle a somewhat extended white band. Both wings possess a whitish violet anteterminal band. The butterfly 
prefers shady woods and is a very lazy flyer, which has to be disturbed in order to be seen at all. According 
to Ribbe not rare on Alu and Bourgainville. According to Ribbe on the island of Ysabel a paler local form 
occurs. 
8. Genus: Atella Dbl. 
This bicontinental Genus constitutes a transitional form between the genera Cupha and Argynnis. From 
the first it is separated by the narrower shape of the forewing cells, the distinctly clubbed antennae and the 
apparently closed hindwing cells; from Argynnis sharply and with certainty on account of the different position
