scarce in the wooded low-lands in north-eastern Sumatra; several specimens from the Bovenlanden above Padang 
teuthras. in western Sumatra in Fruhstorfer coll. — teuthras Hew. from the Malay Peninsula and Singapore differs from 
atlita in the presence of a yellowish area irrorated with violet beyond the cell in the hindwing which reaches from 
fulminans. the submedian to the lower radial, but does not recur on the under surface. — fulminans Btlr. (phalaris Weym.) In 
this form the basal half of both wings is dark violet instead of blue, the scent-scale patches on the forewings are 
bordered with reddish-brown and the hindwings have an immacnlar reddish-yellow anal area, which has a violet' 
tinge and reaches the cell. Specimens from northern Borneo are larger in size and provided with richer red-brown 
bands than those from the south-eastern part of the island. Shelford mentions a form from the Batang Lupar River 
in Sarawak which approaches teuthras. The ? of fulminans seems very scarce; it is not represented in my coll. 
T. abisares. Although this species closely approaches Clarissa, both with regard to the outline of the wings and 
the general style of marking, and represents the continuation of that species in the east, it is given a place here on 
account of its identity in structure with T. atlita. The under surface is gray, the forewings with several conspicuous 
rows of reddish spots which do not unite to form a coherent band as in Clarissa. Hindwings with an intramedian, sharply 
serrate, reddish submarginal band and with huge, elongate red-brown patches placed beyond the cell. The scent- 
patch on the upper surface in the cfcd covers nearly the entire cell, on the hindwings it continues to the upper 
median. ? not unlike that of clarissa-% , but with much less blue; the anal area is darker red-yellow and, as in 
clarissa diunaga , traversed by a conspicuous undulate subterminal band; besides it is adorned with four intramedian 
abisares. limular spots. Two local forms must be distinguished; abisares Fldr. (108 d), which inhabits the northern part of the 
island, where 1 have met with it near Toli-Toli at the border of the woods near the shore, in November and 
poros. December, and poros Fruhst. This form differs from abisares Fldr. from northern Celebes in the same way as 
amplior does from taxiles. The reddish-yellow portion of the hindwings becomes duskier at the anal angle and shows 
a tendency to disappear altogether. The underside grows lighter and more indistinct. All the longitudinal bands 
assume a. a pale-gray hue and the spots on the median area become obsolete. The sexual organs have been des¬ 
cribed in the diagnosis of this genus. From the vicinity of Maros, where it. occurs from November until January. 
T. taxiles, erroneously described by Hewitson as coming from Celebes; its real home is Batjan, as has been 
first shown by Wallace in 1869. The contours of the wings are still more rounded than in abisares , the red colour¬ 
ing of the anal area in the hindwings is reduced, but the forewings show in its place an orange-coloured spot before 
the apex. ? is black-brown in colour, with faint, traces of blue spots and the anal area wholly obscured. Also the 
underside is duskier than in abisara, but with more prominent red-brown bands and spots. There exist four 
taxiles. local forms: — taxiles Blew. The upper surface of a beautiful violet-blue colour, with a glossy velvet-brown 
scent-scale spot which does not cover the cell so completely as in abisares. The under surface displays a 
amplior. number of very broad red-brown as well as some exceedingly narrow gray-bands. From Batjan. — amplior 
Fruhst. This species lacks the yellow subapical spot at the Costa, which plainly appears on the upper surface of 
the forewings in the form from Batjan (v. Hewitson’s figure 4). The reddish terminal area on the upper surface 
of the hindwings is considerably reduced assuming in some specimens a gray hue, in which amplior forms a 
transition so the form helleri Fruhst. from Waigeu. Beneath the wings are more lavishly adorned with paler gray 
bands than in taxila. In the ? we notice two gray-yellow bands along the distal border of both wings, and the 
forewings contain a rudimentary reddish gray median fascia beyond the cell. The submarginal lunular spots on 
the hindwings continue to the costal border, being nearly Iwice as broad as in abisares Fldr. and in poros Fruhst. 
helleri. from Celebes. From Halmaheira. — helleri Fruhst. Looking at the upper surface of this form one might get 
the impression of its being a separate species, chiefly because we miss one characteristic feature of the Terinos 
namely the violet or blue iridescence on the basal half of both wings; its place is taken by a peculiar, dull, dusky 
red-brown colour, upon which the large scent-scale patches are clearly distinguished by their plush-like lustre. 
Otherwise helleri appears to be the plainest among all the Terinos with regard to design and colouring. The anal 
angle is pale brown; on the hindw. one just notices the submarginal bands which faintly show through from the 
underside. In the ? the distal border of both wings is somewhat lighter and adorned with two pale yellow submar¬ 
ginal bands. The median area of the forewings and the anterior half of the hindwings are shaded with dark brown, 
whereas the basal half is chocolate-brown, but somewhat paler than in the cTcT. The hindws. are in the anal portion 
light coffee-brown, the spots on the underside reappear quite distinctly also on the upper surface. The under sur¬ 
face has preserved the characteristic features of taxiles, which has caused us to unite helleri with the latter. — helleri 
is considerably darker brown than both taxiles and tethys, the red-brown longitudinal bands however are more in¬ 
distinct. The distal border of the hindws. grows steadily lighter reminding us of tethys, but the outer border is not 
yellowish as in tethys, but gray-brown. From Waigeu. The British Museum contains another, fourth form which is 
distinguished from taxiles and amplior by the lighter blue areas above and the larger median bands of a glossy sil¬ 
very white on the under surface of both wings. It is said to come from Amboina, but this is presumably an error. 
T. alurgis closely follows T. abisares from Celebes, the apex and the anal portion being even more elongate. The 
blue colouring is more brillant, reminding us of the forms of clarissa, which indeed it approaches in the ? much more 
closely than it does the forms from the Moluccas, although geographically speaking it is nearer to the latter. - 
alurgis. alurgis Godm. (108 d) from Port-Moresby, British New Guinea, above brillant blue. The scent patch on the forewings 
extends but imperceptibly beyond the end of the cell. The hindw. resemble clarissa in the markings of the anal portion
