E. caelipunctata Lathy resembles the forms of the preceding species, having like this the red caeli- 
abdominal bands incomplete above; but the first segment has above a crimson spot, and there are no blue P u,lll " t "- 
rings. Island of Burn. 
E. ekeikei Beth.-Bah. has the forehead black margined with white, head, tegulae, shoulders and patagia ekeikei. 
rich metallic blue-green. Thorax black, abdominal segment 1 creamy-white, 2 and 3 black with broad metallic 
border; the 4 middle segments crimson beneath. Forewings rich metallic blue-green at base and at apex of 
cell. An hyaline longitudinal spot near the base, 2 large median spots in the cell, the lower one very large 
and irregular; 2 longitudinal spots between 3 and 5, another very long one between 6 and 7. On hindwing 
3 large wedge-shaped spots separated by the ribs, beyond the cell an hyaline band composed of 4 spots, and 
a band of metallic blue-green at the apex of the cell. 54 mm. Ekeikei, March and April; Mafalu, August. 
E. col laris Swinh. Frons white, tegulae orange-red, 1 st abdominal segment half white and half orange- collaris. 
red; 2 nd and 3 rd metallic blue banded with black, 4 th black, the remainder crimson banded with black. 
Forewing with hyaline spots, one wedge-shaped in the centre of the cell, below it another large and heavy 
spot, and 4 longitudinal ones in the disc. On the hindwing the basal and discal bands are united, leaving 
nearly the entire wing transparent. Shortlands Islands. 
E. paula Rob. (12h) is dull black above, the hyaline spots rather small, abdominal segments 4—7 paula. 
narrowly bordered with pale grey-yellow. Metathorax covered with yellow hair behind. Abdomen ventrally 
with 4 red bands. Celebes. 
E. irius Bsd. (= boisduvalii Montr., aruica Wkr.) (12 f), widely distributed throughout New Guinea, iritis. 
very common also in Mysol, Arou and the Moluccas, resembles neglecta occidentalis Rothsch. to which it 
undoubtedly is closely related. Like this it has segment 1 brass-yellow, 2 and 3 sky-blue; but the following 
segments are above not dark red with fine black borders, but black with very fine red margins. 
E. pratti Beth.-Bak., is not unlike irius Bsd. Shoulders creamy-white, 1 st abdominal segment ochreous, pratti. 
the two subsequent ones black, broadly banded with metallic pale greenish-ochreous, the 2 or 3 next ones 
black with brillant crimson border. Beneath the 3 or 4 middle segments banded with red; forewings jet- 
black, a small hyaline spot in the cell, 2 larger median spots, the lower one twice the size of the upper one, 
2 elongate ones between ribs 3 and 5, another similar one between 6 and 7 and, beneath it, a short, and 
narrow streak. Hindwing with milky-white longitudinal spot in cell, beneath which I or 2 spots, which may 
occasionally be absent; a broad hyaline band beyond the cell. — Both wings with metallic spot at apex of 
cell. ? characterized by white patagia and the richer red abdomen. 51 mm. Ekeikei, March and April. 
E. creusa L. (= thelebas Cr., irus Cr., ganymede Dbl .) (12 i) is the oldest and largest species known. North creusa. 
Australia, Fiji Islands, New Guinea, Celebes, New Hebrides, Pelau and many of the smaller South-Sea Islands. 
The anterior 3 segments are deep blue, the remainder of the abdomen dark blood-red; all segments finely 
margined with black. Abdomen beneath from the 3 rd segment on clear scarlet throughout. Specimens from 
Ceram and North-Australia have the first abdominal segment occasionally blackish. Looking at them from the 
side, the hyaline spots of the wings are distinctly blue-green. Seems to be very common in some places. 
E. shortlantica Swinh. Black, frons and 1 st abdominal segment greyish-yellow, the latter with a blue shortlantica. 
central spot; 2 nd and 3 rd segments metallic blue, banded with black, the remaining segments crimson with 
black rings. On forewing a few blue markings at base, both wings have the discocellulars blue, and are 
spotted as in creusa. Shortland Island, Solomon Archipelago. 
E. salomonis Swinh. Body as in shortlantica, but the first abdominal segment with 2 brown spots salomonis. 
and without the metallic blue central spot. On forewing the spots larger, below the upper discal dot a white 
stripe, the lower median spot reaching the subbasal streak and extending broadly to near the base. On the 
hindwing the basal band is generally divided by the ribs into 3 spots the upper one of which is much longer 
than the others. Ysabel, Solomon Islands. 
E. walkeri Hmps, (12i) has head and thorax black, with metallic blue spots; forehead white, abdominal loalkeri. 
segment 1 dull greyish-white, occasionally with strong blue tinge, 2 and 3 pale blue, 4 and 5 dark purple, 
6 and 7 blackish with dark blue gloss. Beneath segments 3—5 are red. The spots on wings smaller than 
in most species. Ternate, discovered by J. J. Walker. 
E. cyanitis Meijr. (12 g). Thorax with metallic reddish-violet lustre. 1 st abdominal segment reddish- cyanitis. 
brown, the remainder orange, tipped with black; all segments margined with black, the 2 nd and 3 rd with
