ker under surface and in having, especially on the secondaries, the longitudinal band still more reduced. I 
found this form in January at an elevation of 1000 ft. Only 1 in the Fruhstorfer collection. — piratica piratica. 
Semp. resembles E. teuta in that the spots on the forewing are much smaller and not notched distally. $ differs 
less from <$ than is the case in teuta , the band of the forewing being, especially near the costa, equally narrow, 
while on the hindwing it widens towards the anal angle. On the latter the black submarginal spots are rather 
square, not triangular as in teuta, and unite into a band which is only separated by the veins; beneath it differs 
but slightly from teuta. Luzon and Mindoro. ■ — sarmana subsp. nov. (131 b as piratica) bears the same relation surma-no,. 
to piratica as affinis Lathy to E. teuta, having on the forewing the yellowish spots making up the band even more 
reduced. Under surface paler than in Mindanao specimens, with nearly obsolete red markings. Discovered in 
February and March by Doherty on the island of Bazilan. — medaga subsp. nov. was already known to Semper, medaga. 
who figured a from Camiguin de Mindanao. A $ from Mindanao in my collection differs from Semper’s 
$ in having the white spots on the forewing hardly half as wide and darker yellowish. deviates from 
that of sarmana in having the yellow macular row of the hindwing nearly twice as large. Under surface darker 
than in sarmana, $ hardly to be distinguished from E. teuta $. 
E. bellata takes in the Macrorr.alayan Region the place of teuta of which I should take it to be a sub¬ 
species were it not for the fact that both forms occurred, together in Tenasserim. hardly differs from teuta <§, 
but the $ is distinguished by a more delicate submarginal undulate band on the hindwing. A number of rather 
sharply separate forms in some of which the white macular band of the hindwing is only represented by two, 
four or six small bluish-white dots, whereas in others (as in the forms from Java and Sumatra) it may be 
very conspicuous. — gupta Nicev. is the form which deviates farthest from typical teuta. It inhabits Upper gupta. 
Tenasserim; one $ discovered by Bingham in the renowned Thungyeem'forest is, together with a pair in the 
Niceville collection of the Calcutta Museum, all we possess of this form. In the ^ the white spots of the 
hindwing are entirely absent, and on the forewing the longitudinal band is only indicated by 5 insignificant 
spots of white. Ground-colour pale brown, laved with yellowish along the black submarginal line of the hind¬ 
wing. The under surface has the outer portion of both wings richly suffused with violet grey. Hindwing beneath 
with a white costal and another, oblong anal spot, otherwise without a trace of a median band. ■—- goodrichi goodrichi. 
Dist., described from Perak, is found as far North as Southern Tenasserim, but beyond, in the northern part it 
is replaced by gupta Nicev. resembles that of eion (131 c), although with smaller yellow spots on the upper sur¬ 
face of both wings. The $ represents a transition to the remaining Malayan forms. Forewing with a 
complete series of 8 blue-white median spots; hindwing with 4 white wedge-shaped markings. The fore¬ 
wing has in addition the submarginal area between the black and white macular rows suffused with grey-violet. 
Exceedingly scarce, only 1 pair in the Fruhstorfer collection. — eurus Nicev. is an excellent insular race re- curus. 
sembling eion (131c), but larger, $ with richer pale lilac ornamentation of the outer portion of both wings. On 
the hindwing the undulate line is more marked than in gupta and goodrichi, the white median band consisting 
of distally sharp-pointed wedges. According to Martin it is found quite near the shore, not even ascending 
the lower foot-hills. Not very abundant; but my collectors brought at one time a fine series from West Sumatra. 
— yapana subsji. nov. appears more nearly related to eurus than to the neighbouring form of Nias. smaller yapana. 
than eurus <J, the median spots of the forewing greatly reduced, much smaller than in externa, but on the hind¬ 
wing larger. Pulo-Tello of the Batu Islands. Type in the Tring Museum. — externa Nicev. might almost externa. 
be conceded specific rights. $ has on the forewing the yellow spots twice as large as in eion (131 c), but on 
the hindwing so much reduced as to stand perfectly isolated. $ resembling goodrichi $, with even smaller, hardly 
recognizable white median striae, but with broadly white instead of pale lilac suffusion, as in eurus. Very 
scarce. Island of Nias. — eion Nicev. described from specimens I discovered in Eastern Java. $ still more eion. 
profusely laved with white than in externa. On the whole it most resembles the continental form E. teuta, a frequent 
occurrence in Java butterflies. This form I captured in large numbers on bananas early in the dry-season (March, 
April) in the Zuidergebergde of Eastern Java, at an altitude of about 1600 ft. Also in Western Java it was found, 
though very scarce, in the forests skirting the bay of Palabuan. — veyana subsp. nov., a surprising discovery veyana. 
of Everett’s, representing a miniature E. eion. Ground-colour pale brown, markings as in eion, only the white 
spots more oblong. Flores, only 1 specimen known, type in the Tring Museum. — bellata Druce (= cenespolis bellata. 
Hew.) coincides as to colouring with eurus, but is paler and the white median band of the $$ is much narrower. 
North Borneo, scarce. $$ also from the South-East of the island in my collection. — salpona Fruhst. $ has the salpona. 
upper spots of the median band of the hindwing somewhat larger than in bellata from North Borneo, rendering 
the band more uniform. Under surface darker than in Borneo specimens, with a more oblong, black-margined 
and pale red-centred spot in the cell of the hindwing, and with broader median bands. Natuna Islands. — eson eson.
