EPIMASTIDIA. By Dr. K. Grunberg. 
a broader band, a white band extending farther towards the border, the black, white-margined spots in the 
hindwing extending more anteriorly, between them and the band besides a series of whitish-blue arcuate mar¬ 
kings. Aru Islands. 
danisoides. Ps. danisoides Nicev. (142 b). above blackish-brown with a broad, white band extending in the 
forewing as far as the base of vein 5. Hindwing with a white marginal line, the black marginal spots small, 
proximally bordered with pale-blue moonspots. Under surface with a broader band and a more distinct marking. 
The spots in the hindwing larger, particularly between the veins 1 and 3. Forewing along the border likewise 
with whitish blue ring-markings. $ somewhat larger and darker, the band broader, the blue distal-marginal 
markings on the hindwing less distinct; beneath the band yellow-coloured, the markings very prominent, silvery 
blue, the forewings only with a single submarginal arcuate line. Key Islands, Milne Bay. 
batjana. Ps. batjana spec. nov. (142 b). Allied to Ps. danisoides. above with a considerably narrower or 
almost quite obsolete band, in the hindwing only along the posterior half of the distal margin with a fine, inter¬ 
rupted, white marginal line. Beneath with a broad band being in the forewing anteriorly narrowed, with a 
pale brownish-yellow touch, the marking silvery blue, similar as in danisoides, the distal marginal line in the 
forewing indistinct. Batjan. 
4. Genus: ICpimastidia H. H. Dr. 
Allied to Thysonotis Hbn. with which the genus corresponds in the neuration. The antennae are some¬ 
what more slender, the transition to the terminal club takes place more gradually. Vein 7 in the hindwing is 
covered with long hair from the base to % of its length, a mark which was pointed out already by Felder. 
There are no metallic markings beneath. The species are untailed. The range comprises the groups of islands 
adjacent to the west of New Guinea, New Pomerania and the Salomons. 
According to observations made by Ribbe in E. bornemanni, the species are fond of sunny valleys watered 
by rivulets and fly swiftly to and fro in the hot midday-sun. It necessitates great dexterity to capture them. 
inops. E. inops Fldr. (142 h). $ above bright blue, forewings quite narrowly, hindwings somewhat more 
broadly margined, the costal margin of the hindwing broadly blackish-grey. Under surface white, forewing with 
a broad, grey-brown costal-marginal border being widened at the apex. Hindwing with a similar broad post- 
discal band; both wings with a double row of blackish submarginal spots on a white ground, which are larger 
and more distinct in the hindwing. Marginal scales dark. $ above white with a blue, in the forewing a little 
more extensive basal colouring, forewing with a very broad blackish-blue margining leaving free only the inner- 
marginal half, in the hindwing the larger distal half is entirely blackish-brown; submarginal spots beneath 
larger than in the <$, more confluent. Aim Islands. 
pilumna. E. pilumna H. H. Drc. Allied to E. inops Fldr. (142 h). above similar to this species. Hindwing 
with a white costal margin, and at the anal margin with 3 black submarginal spots touching the border of the 
same colour. Under surface: the dark costal-marginal border in the forewing broader than in inops, enclosing 
at the costal margin of the cell a narrow, grey line; the submarginal spots larger and more prominent, the inner 
margin grey-brown; the dark band in the hindwing broader and the black spots larger, the white interspace 
removed except a narrow border, the 3 posterior spots of the distal row covered with light-blue lustrous scales. 
$ above very much like inops- $, the bases of both wings densely scaled in a bluish-green; beneath like in the 
<3, only the inner margin of the forewing is white. New Guinea (Humboldt Bay). 
staudingeri. E. staudingeri Rob. (142 c). Closely allied to E. arienis, the upper surface of the $ very similar, but 
the black border of the hindwing very undulate, the inner margin of the hindwing whitish-grey; under 
surface dirty white, the broad border grey-brown, the inner margin of the forewing grey; the distal submarginal 
spots greyish-black, the proximal ones black. $ above dirty white with a broad blackish-grey margining, in 
the hindwing the black marginal spots faintly showing through from beneath; ground-colouring of the under 
surface somewhat darker than in the $. Ceram. According to Ribbe (1899), arienis and sodalis would have 
to be placed as synonymous to staudingeri ; they are here quoted separately, since the descriptions and figures 
make differences at any rate very evident. 
arienis. A. arienis H. H. Dr. above lustrous blue, the distal margin in both wings quite narrowly bordered 
with black, the hindwing with a blackish costal and inner margin. Under surface white, both wings with a 
broad, grey-brown border in which there are between the veins round black spots which are proximally margined 
with whitish and exhibit at the distal margin a whitish spot; the latter spots partly covered with blue scales. 
Salomons. 
sodalis. E. sodalis Sm. & Ky. (142 h). Closely allied to E. arienis with which it greatly corresponds in the 
marking beneath; above to a little beyond the middle of the wing white, the whole distal part and a narrow 
costal-marginal border in the forewing black. Basal parts in both wings darkened and strewn with dull-bluish 
scales. It may be the $ of arienis (according to Smith and Kirby). New Pomerania. 
bornemanni. E. bornemanni Pagenst. (= albocaerulea Gr.-Sm.) (142 c). Upper surface of the <$ very much like 
E. arienis, the blue of the upper surface more brilliant, in the broad, brownish-black border of the under surface
