metallic blue lustre above. All the hyaline spots excepting the one at base of forewing large, with bluish 
gloss. Abdomen banded with red beneath. New Guinea. 
E. plagosa Swinh. Black, frons white, patagia grey-yellow; 1 st abdominal segment grey-yellow, 2 nd 
black, 3 rd metallic blue with white central dot, 4 and 5 orange, separated by black lines, the two last ones 
black with blue rings. Wings spotted with white. Resembles cyanitis Meyr. New Pommern. 
E. aemulina Btlr. (12 g as aemulia), resembles in colouring auranticincta ( 1 2 f); the first abdominal 
segments yellow, the remainder purple, but segments 2 and 3 clouded with whitish and all the abdominal 
segments broadly banded with black. Collar and l 6t segment orange. New Guinea. 
E. epa Beth.-Bak. is very close to aemulina Btlr. Metallic blue-green, frons white, tegulae, shoulders, 
abdominal segments cream-coloured, the latter from the 2 nd onwards with black basal margins, increasing in 
width toward the anal segment, which is quite black. Forewing with small hyaline spot at base of cell, 2 
more in the middle, the lower twice the size of the upper one, two oval spots between ribs 3 and 5, and 
another, suboval one between 6 and 7, below which a small hyaline dash. Hindwing with milky-white 
longitudinal spot at the base of the cell, 2 short, narrow spots below, and an hyaline discal band beyond it. 
Both wings with a metallic lunulate spot near the apex of the cell. 48 mm. Ekeikei, March and April. 
Type in the author’s collection. 
E. gemmata Btlr. (12 f) has the collar red, shoulders bordered with yellow, 1 st abdominal segment 
orange; the remainder of abdomen ventrally and laterally likewise orange, dorsally brillant metallic blue. 
Solomon Islands, Halmaheira. 
E. isis Bscl. (12 g). Collar, shoulders, 1 st , 3 rd and 4 th abdominal segments orange; otherwise black 
with bright metallic blue lustre. Wings spotted as usually. Duke of York Island; Bismarck Archipelago, taken 
on the shore near Ralum in September. — mathewi Btlr. from New Georgia which is united by Pagen- 
stecher with isis , has the collar and the last abdominal segments red. 
E. lurlina Btlr. (12 g). Collar brownish, shoulders margined with dull pale brownish. 1 st segment 
pale yellow, 2 nd and 3 rd pale blue bordered with darker, 4 th brownish-orange, 3 rd laterally spotted with orange 
New Guinea, Louisiad Archipelago. It is not certain whether it also occurs on Thursday Island. 
E. rubricollis Wkr. (12 g) has the collar red, shoulders bordered with pale red; 1 st segment with 2 whitish- 
yellow lateral spots, the remainder of the abdomen with broad steel-blue and narrow whitish-yellow bands, in the

P. 63. 
In Zerny’s Catalogue of Syntomids (Lepidopt. Catal. Pars 7, p. 8) it is mentioned that another form 
than the one figured in Hampson’s Catal. Lep. Phal. I, p. 35 has been described later under the name of 
Ceryx pleurosticta. For this he proposes the name laterimacula Zerny ; habitat Canara, whereas that of 
pleurosticta limps, is Labuan (Borneo). 
C. finitima Wilem. is one of the many insects discovered within recent years in Formosa. ? blackish, 
thorax and abdomen marked with yellow, the latter with yellow sides. Forewing with 7 spots, one each in 
and below the cell, 1 larger one in the intramedian space, and 4 others traversing the wing beyond the cell, 
the second one of which small. Hindwing with broadly black borders and pale central area intersected by 
the black ribs. Unknown to me in natura. 
P. 64. 
C. godarti Bscl. ( = libera Wkr., cupreipennis Btlr., fytehei Moore ) (9 f), which has repeatedly been 
described as a Syntomis , belongs rather to Ceryx. Wings somewhat like those of C. decorata (10 c), but thorax 
less yellow, and the abdomen has only at the base and on segment 5 a yellow band. Common, but only 
locally, from the Himalayas south as far as Southern India and Ceylon, eastward to the southernmost 
provinces of China. 
For Ceryx subformicina, described in 1904 by Bethune-Baker, Hampson later on established the Genus 
Paralaethia. The species is figured on pi. 9 h.
