EUTHALIA. By H. Fruhstorfer. 
canescens . a rule somewhat bigger, with larger and paler spots on the upper surface. — canescens Btlr. (127 a) has the 
macular rows on the hindwings not always red-brown as in our figure, but usually pale clay-yellow. In the $ 
the spots are larger, those in the median area of the forewing changing to white; moreover, the submarginal 
macular row of both wings is in the middle and at the anal angle also whitish. South-East Borneo, of local 
leopardina . occurrence; scarce. — leopardina subsp. nov. refers to a lovely form of the Sulu Islands in which the white 
colouring reaches its maximum, the forewings being, with the exception of the black cell, almost completely 
white. On the hindwing an entirely white submarginal band and pale yellow median spots. Under surface of 
the forewings likewise completely white, hindwings with the exception of a yellow anterior portion suffused 
pardalina . with whitish-blue. Type ($) in the British Museum. - — - pardalina Stgr. is the opposite, melanotic extreme; 
forewing with larger yellow patches than in canescens Btlr. from Borneo, but in the $ lacking the whitish-yellow 
spots characteristic of that form, giving it an almost male appearance. The $$ lack on the under surface of 
tigrina. the forewing the indistinct whitish blotches of canescens. Malay Peninsula, exceedingly rare. —- tigrina subsp. 
nov. appears to be a retrogression toward the Borneo form, the ES having the forewings spotted with whi¬ 
tish instead of yellowish. According to Hagen not very scarce in Bangka. Type in the Tring Museum. — 
civetta . civetta subsp. nov. has among all the forms of the species the smallest spots. Beneath darker than pardalina 
or tigrina ; fore wings with reduced yellow-brown median spots. $ almost exactly like <$. According to Dr. 
Martin it is only found on the Tableland of Sumatra, always scarce. One $ in my collection from Palem- 
bang, taken in the lowlands, where also in Borneo canescens is exclusively found. 
etna. E. elna van de Poll. (127 d) takes the place of canescens in Mas. Especially on the under surface the white 
areas of the forewings are still larger, being arranged somewhat as in the $ of E. perdrix Btlr. of the same 
island. E slightly smaller than the $ of our figure. Beneath it resembles most E. canescens, but has on the 
hindwings the anal angle more deeply suffused with lilac. 
(3) Palpi blackish or greenish-brown, in $ occasionally with whitish 
lateral stripes. 
E. aegle takes the place of dirtea in the Micromalayan islands, whence so far only two geographical 
aegle . races are recorded, namely from Sumba and Flores: aegle Doh. $ black above, with a few dark greenish 
spots near the costa, three in the cell (2 at its apex), two in the inner median area, one basal dot and, slightly 
distant, a few others; a row of 5 white subapical spots extending to the second median vein, the second 
dot being the largest, the third obsolete. A submarginal band of dull bluish-white dots, the lower of which 
sagittate, extends from the anal margin to very near the apex, the spaces between being dull blue-green. 
Hindwing with a broad green band enclosing distally pointed black patches and margined by a broad, jet- 
black terminal border encroached upon by delicate rays of green. Under surface of the fore wings black with 
brown suffusion of the apical area and with two rows of oblicpie white spots. Between the median nervules and 
above each radial some more dots; the cell traversed by two blue-white bands, one in the middle, the other 
at the end, and with some isolated dots. Hindwing purplish-brown with bronze lustre; the paler distal half 
traversed by a submarginal band formed of dark spots; in the cell three light brown spots, in the discus an 
irregular row of five spots. The colour of the under surface, the narrow, pale blue band and the numerous 
spots easily distinguish aegle from dirtea. One E was taken at Pada-Dalung, one $ at Mandas, Sumatra. Do¬ 
herty could not give any description of the presumably it approaches the $ of floresina Fruhst., with 
numerous white dots on the forewings above and two or three rows of yellowish spots on the hindwings. — 
floresiana . floresiana Fruhst P $: Upper surface of forewing like that of aegle, but with all the spots and dots larger 
and paler. The hindwings share with aegle only the deep black ground-colour. Within the submarginal band 
an irregular row of 5 unecpially large dots distributed between the costal and upper median veins; the upper 
blue-white, about as large as the second, clear white one; the three following are much smaller and yellow¬ 
ish; the band resembles that of aegle, composed of three colours, pale blue prevailing, gradually fading 
to yellowish towards the anal angle. The spots separated from each other by black veins and sprinkled with 
whitish scales, more profusely toward the anal angle. The black, heart-shaped patches within the band are 
bordered distally by large, partly elongate, partly long pointed, white spots narrowly edged by blue, deeply 
encroaching upon and cutting into the black outer border, which is much narrower than in aegle. Ciliae black and 
white, inner margin of the hindwing covered with pale yellow hair. Under surface of the fore wings deep black 
with brown apical area; all the spots larger and paler than in aegle, only those in the cell smaller. Hindwing 
with dull dark brown basal and pale yellowish outer half. The three dots in the cell, as well as the median 
row distinguishing also aegle beneath, are pale yellow, forming a vivid contrast with the ground-colour. An¬ 
tennae as in aegle ; the eyes, however, black instead of red-brown; palpi much paler; body above resembling
