EUTHALIA. By H. Feuhstoefee. 
brillant gulden-brown. North Borneo, Kina Balu, 5 in Feuhstoefee’s ; 7 99 from Sintang and South- 
East Borneo in Staudingee’s collection. One $ from the Sulu Archipelago in the British Museum. 
E. kanda of which only the was hitherto known, is one of the plainest-looking Euthaliidi. Above 
unicolorous dark umber-brown of a peculiar golden-green bronce lustre. On the forewing the cellular spots 
as in apicalis, both wings traversed by slightly undulate black lines closely approaching each other on the hind¬ 
wing. Beneath it resembles a very pale merta but with much more delicate markings. An essential charac¬ 
teristic to distinguish the sexes by are the black crescent-shaped rings at the end of the cell in the forewing, 
which are narrower and more compressed than in any other Euthalia. Antennae quite red beneath, above 
as far as the middle brillant pale fulvous, differing from those of all other species. The $ which resembles 
Tan. pelea or palguna, has been known since 1862 under the name of surjas Voll. without being recognized 
elicius. as belonging to kanda. 4 local forms deserve mentioning: elicius Nicev., described from Burma and Tenasserim; 
the dry-season form distinguished from the Macromalayan allies by the pale yellow colouring of the under 
kanda. surface, resembling E. merta fa. pseuderiphyle. — kanda Moore ($ = surjas Voll.) seems to be very scarce. 
The <$$ are found in all the larger collections, but of the 9 I only know 3 specimens in the British Museum, 
whereas it is not represented in either the Tring or Statjdingee collections. Beside the form of the southern 
surjas. part of the island = surjas Voll. we know also darker 99 from North Borneo, having the broadly white median 
band of the hindwing dusted with grey or brown, the marginal band brown, strongly undulate and continuous, 
somewhat like in E. salat, bipunctata Voll. 9- From salia 99 they are easily separated by the absence of the blue 
basal colouring of the hindwing, this being replaced by a faint suffusion of milky-white. Borneo, Malay Pen- 
at,js. insula. — atys Fruhst. (137 as surjas) inhabits North-Eastern Sumatra; in the Munich Museum I think 
I saw also some from Banka, atys differs from surjas in the more pointed outline of the forewings. The sub¬ 
marginal dentate markings of both wings are less sharp, but accompany the veins as far as the outer margin. 
The median band which in surjas is dusted with brown on the forewing, but nearly obsolete on the hindwing, 
is in atys clear white as far as the anal angle of the hindwing, and scaled with grey-brown only between the ra- 
dials and the upper median. On the hindwing, moreover, the brown submarginal dentate band is margined 
with white distally, broadly at the apex, gradually fading out toward the anal angle. Both wings with paler, 
whitish violet markings beyond the cell. The under surface resembles many forms of Tanaecia, on account of the 
blurred indistinct colouring of the brown-yellow basal and whitish-blue distal areas. The red-brown proximal 
bordering of the white bands is somewhat more sharply serrate than in surjas. Beneath atys differs in the 
richer blue-Avhite colouring of the marginal area of the forewing. Deli, scarce. 9 type in the Feuhstoefee 
yhincas. collection. — phineas subsp. nov. lately discovered in Nias, is larger than atys from Sumatra, kanda from 
Borneo and elicius from Tenasserim, with sharper, much wider and heavier black longitudinal bands of the upper 
surface. Originally in the Van De Poll collection, it is now in the Adams collection of the British Museum 
E. agnis , one of the rarest species of the genus, inhabits exclusively Java and Sumatra; 
although it has not yet been found in the Malay Peninsula or Borneo, it will most likely be discovered 
also there, where also the parallel species E. tinna is known. The sexes differ to an unusual degree. The 9? 
are more abundant than the which of the Javanese race were only discovered during my trip to Java. 
$ resembles above E. tinna Fruhst. (130 a), coffee-brown with purplish lustre; beneath easily separated from 
all the other members of the genus by the peculiar grey-white lustre, suffused with violet, resembling that of 
the .South American Prepona, margined by delicate brown stripes and traversed by faint, nearly obsolete bands 
of a similar colour. 9 somewhat like E. vasanta Moore 9. but the under surface is brown-grey, without 
any milky-white or pearly lustre. The genitals are distinguished from those of the other species by the perfectly 
flat cylindrical valve being cut off straight anteriorly. Uncus somewhat more robust and longer than in E. 
aijnis. salia. The imago is only found in the mountains, never below an altitude of 3800 ft. — agnis Voll. (129a 
<9 b 9 ). The 9 this rare species was in 1862 described and figured by Snellen Van Vollenhoven (in Tijd- 
schrift voor Entomologie Vol. V, p. 252, pi. 12, fig. 2). The species is dimorphous, the differing greatly 
from the 9- which most resembles Euth. vasanta. Moore , whereas the <$ looks rather like that of E. garuda 
Moore. The J I discovered on the Vulcano Gede, and it was figured in Berk Ent. Ztg. 1894, on pi. 18, f. 8. Upper 
surface: Ground-colour of both wings dark coffee-brown, interrupted by a somewhat paler submarginal band. 
Forewings with two small triangular, dirty-white, apical patches and a subapical row of 5 similar spots
