deep ochreous spots and bands above; b) ergena form. nov. with white apical and cellular spots on the fore wings, ergena.

around with canary-yellow, thus resembling the $$ of the Moluccan forms, although by no means so profusely 
white as f. i. from Saparua. Obi and Buru. All the $-forms of eutychius are beneath paler or darker ochreous, 
albifera -$ excepted, which in its white basal area resembles the white $ form choirilus. The black submarginal 
spots on the under surface of the hindwings vary considerably, being on the whole more conspicuous than in 
choirilus and most marked in the $-fa. midia from Finschhafen. The A (127 a) has the bands of the hind- 
wings considerably narrower anally. - — - hegias subsp. nov. from the Bismarck Archipelago is of smaller size than hegias.

near the shore only one $ of the white type. 
Subgroup Euthaleopsis. Van de Poll. 
In structure approaching Lexias, having the cell in the fore wing closed. On the fore wing the second 
subcostal nervure is absent, the first united with the costal, the third arising in both sexes a short distance 
beyond the cell. The group comprises only one species with an enormous eastward range; in colouring it resem¬ 
bles the E. lubentina group. 
E. aetion differs sexually in that the are larger, with more rounded wings, which are spotted 
rather canary-instead of pale yellow. The sulphur-yellow area of the <$ hindwings above may be in the shape 
of a band, or more circular, as in donata (130a). Underneath the colour varies according to the locality from 
grey to black brown; likewise the white submarginal spots which replace the black or red patches characterizing 
the other Euthaliidi, vary somewhat in being more or less distinct. Hagen supposes that the larva is found 
like that of Lexias aeropus eutychius Fruhst. on Calophyllum trees. In some years the imago is quite common, 
in others hardly one specimen may be seen. Its range extends from the Northern Moluccas through New Guinea 
to the Bismarck Archipelago and the Louisiads. — plateni Stgr. is the darkest race of the entire species, plateni. 
The yellow median spots of the are smaller than in the Melanesian forms, and steeper. Under surface 
nearly black, the red basal stripe of the hindwing especially prominent. Batjan, Halmaheira, described from 
2 <$$. — donata Fruhst. (130 a) from Waigiu has the spots pale yellow like in aetion Heiv. (Type from Aru); donata. 
on the forewing the discal spots, particularly at the apex of the cell, are barely half as wide as in Aru specimens; 
also on the hindwing they are smaller; the submarginal spots on the fore wing more obsolete. — philomena philomena. 
Fruhst. (130 a), based on specimens from Kaiser Wilhelmsland, was found by Doherty in larger numbers 
on Humboldt Bay. $ rather variable; the yellow twinspob at the end of the cell on the under surface of the hind¬ 
wing may be absent, blurred or quite distinct. Some $$ have, as in our figure, the yellow dash on either side 
of the submedian on the forewing above distinct, others obsolete or only indicated by a few scales. From the 
name-type, philomena differs in the deeper yellow colouring of the spots on the forewings and the reduced sub¬ 
marginal dots, beneath especially in the reduction of the pale area which in aetion fills the entire middle of the 
wing. — sosisthenes subsp. nov. has on the forewing the yellow stripes reduced, but the discal area of the hind- sosisthenes.

and a few other islands adjacent to Eastern New Guinea. -—- aetion Hew., described from a $, has always aetion. 
been rare. It most resembles donata (130a), but the $ has the sulphur-yellow bands above broader; beneath 
the white as well as yellowish-white areas are larger than in $$ from Waigiu and Aru; not known from the Key- 
Islancls yet. —- thilei Ribbe, a melanotic race with very small discal spot on the hindwing above. Herbertshohe. thilei.

semi-band rather narrower, but longer; the hindwings lack underneath the whitish-yellow discal area, which is 
reduced to only two minute dots. Neu-Hannover. 
Tribus Apaturidi. 
In this group we meet for the first time larvae without any spines, in contradistinction to all the pre¬ 
ceding groups, the caterpillars of which are covered with spines. The main characteristic is therefore the shape 
of the larva, in which the Apaturidi differ both from the hitherto described groups, and from those of Anaea 
and Nymphalids s. s. ( Charaxidi). The larvae of the Apaturidi are either smooth or densely covered with very 
fine tubercles, tapering on either side, with only 2 blunt or bifid horns at the head. The tail terminates in 
2 short spines which are usually folded close together, forming a conical projection. On the 7. segment the grown
