1072 KORUTHAIALOS; SANCUS. By Dr. A. Seitz. 
G. sanguinocculus Mart. (170 b). Upper surface similar as in scantily spotted ihyrsis, with rounded 
spots, only the spot in the cell is larger. The forewing above lacks the scent-organ at the principal veins; 
beneath there is near the base of the hindwing a yellow spot. Perak, Sumatra. 
31. Genus: BCoriithaialos Wts. 
The members of this genus are easily recognised by their colouring, most of them exhibiting a glaring- 
red band on the fore wing, at least beneath. It is besides conspicuous by its mark represented by a stripe¬ 
shaped bundle of bristles at the base of the costa in the hindwing. According to the extent of the red band of 
the forewing a number of species have been distinguished, but I have not been able to keep all the ,,species“ 
asunder. The. shape, extent, and in a certain sense even the colour and portion of the red band of the forewing 
vary even in specimens from the same place, where they were collected, to such an extent that Swinhoe justly 
affirms that two quite similar specimens are very difficult to discover. We therefore only distinguish a group 
of large (55 mm) and one of small (35 mm) lepidoptera. 
K. xanites Btlr. (170 c), from North Borneo and Bali, does not differ from the Malaccan form 
figured by Distant. The red spot of the forewing is not so broad as in the figured Philippinic form Iuzonensis 
Fruhst. (170 c), at least in its costal portion, but both the forms hardly differ from each other. — In narnata 
Fruhst. (170 d), from Sumatra, this spot is more reduced, so that it becomes a triangle beneath. — In javanites 
Stgr. (170 c) the red band is in the centre beneath very much strangulated and on the forewing above reduced 
to a punctiform spot. — in verones Hew. (170 d) the red colour has almost disappeared above. — In gopaka 
Fruhst., from Tonkin and Annam, taken in November and December, the band above is almost as in typical 
xanites from Malacca, but beneath narrower and paler red. — niasicus Fruhst., from Nias, regarded as a separate 
species by its author, shows but very feeble traces of the red spot of the forewing as in the figured Javanese 
specimen. Some of these forms already form transitions to the following rubecula, and it has not yet been 
decided whether those authors combining the rubecula-iorms with the xanites, as for instance Swinhoe, are 
right in doing so. 
K. rubecula Plotz (170 d). We copy the author’s figure. It originates from Borneo and differs so 
little from the Sumatran and Malaccan form hector Wts. that some have united them. On the whole, all the 
rubeciila are of a deeper black ground-colour, and the decorative band is more hemochrome than miniate. 
It is besides narrower, more band-shaped than in most of the forms of xanites. — laetitia Plotz (170 d), 
likewise from Borneo, shows a particularly very long, narrow, stripe-shaped band, and gemmifer Sm.p. nec Dist. 
seems only to be the Philippinic form of it. — palawites Stgr. (170 cl), from Palawan, in my opinion belongs 
rather to this species than to xanites, but by the reduction of the decorative band it corresponds to its form 
javanites. — In haraka Fruhst., from Bali, the red colour above is almost entirely extinguished except traces 
of the cell-end. The species is not common in most of the districts. 
K. focula Plotz (170 b, c) differs from the preceding ones above all in its considerable size (length 
of forewing even in small $<§ more than 2 cm) and in the red band of the forewing being irregularly defined. 
The typical form (= kophene Piep. nec Nic.) comes from Java, where it flies in the Province of Prajangan, 
but it is not common. — kophene Nic. (170 c) is the Sumatran form distinguished by the red band of the forewing 
beneath extending almost to the costa. Rare. 
K. butleri W -Mas. & Nic. According to the morphological investigation by Edwards, it is very 
closely allied to the preceding ones, but distinguished by the d showing neither above nor . beneath the red 
transverse band, whereas in the $ it is invariably present beneath and to a reduced degree sometimes also 
above. Sikkim. Assam. 
K. avidha Fruhst.. from South Annam, is allied to butleri, but it has an indistinct though rather long 
dark red-brown band at the anal margin. Taken in February. 
K. kerala Nic. This species recalls xanites, but the bright light red band of the forewing has entirely 
the shape of the band of Keroma arrnatus Drc. (175 c), the decorative band above not quite reaching the costa 
nor the anal-marginal portion or hincl-margin. The band is otherwise twice as long as it is broad and beneath 
more extensive than above. Malacca and the Battak Mts. of Sumatra. 
32. Genus : Ssmciis Nic. 
The genus contains but a few forms of lepidoptera being above and beneath dark brown almost without 
any marking. The forewing is somewhat truncate at the apex, and in the species upon which the genus was 
founded, it exhibits a very peculiar scent-organ, i. e. a somewhat radiatiform basal wedge of erect scales
