Most specimens have the outer area of the upper surface dusted with dark green. — somadeva Fldr. refers somudcva. 
to a $ form distinguished by sharply defined, broadly black-brown submarginal bands and by having the outer 
half of the forewings distinctly white; the under surface of the forewings with a submarginal band widening 
towards the costa. Forewings moreover with isolated broad median spots of white. • — • laverna Dist. (133 d luverna.

(pi. 14 f 7). An analogous form occurs in Borneo described as bipunctata Voll. — erana Nicev., a local form of erana. 
north-eastern Sumatra, apparently still more variable than monina monina from Perak. A large number of 
the d'cj can hardly be distinguished from decorata from Singapore; but the $$ are easily recognized by 
having on the forewing the brown dentate band very slightly edged with white proximally, and the median 
spots shaded with grey or purple and isolated. The median area of the hindwings is, however, broader and clea¬ 
rer white, and there are $$ which are either grey or suffused with purple all over, or have the submarginal 
area of both wings violet. A number of BS belong to fa. ramada Moore, others approach the Javanese salia ramuda.

Of the $ we find two types: a) unicolorous grey, but with clear white bands broader than in erana 
b) a much rarer form having the hindwings suffused with blue-violet. — - viridibasis Fruhst. refers to a $ form viridibasis.

— inspersa Fruhst. is intermediate between the Macromalayan decorata Btlr. and erana Nicev. and the Micro- inspersa. 
malayan salia obsolescens Fruhst. The white median band of both wings has a tendency to become obsolete, 
being obscured by numerous scales of grey-brown. Both wings have the anal area sprinkled with grey-green;

having the broad median area of the hindwings laved with flesh-colour. This form seems to be more nearly 
related to decorata Btlr. from the Malay Peninsula than to laverna Btlr. of Borneo. From decorata it differs in 
that the black submarginal markings of both wings are more pointed and encroach more deeply upon the intra- 
nerval spaces, particularly on the hindwings. The white helmet-shaped spots accompanying the black dentate 
band proximally are larger. On the hindwing the white median band is from the anal angle to the first 
median much more broadly suffused with dark violet than in decorata. On the under surface both wings have 
the distal area broadly white, covering nearly % of the wings, the base paler, light yellow. Natuna Islands. 
-—- bipunctata Voll. (128 b) is the oldest name given the Borneo form which displays a truly bewildering variabi- biyunclqiu. 
lity. Not only re-occur here all the variations which we meet with in Perak and Sumatra specimens, but quite 
a number of new ones not found elsewhere. My collection contains an instructive series of specimens represen¬ 
ting a complete circle of polychromous forms; of all shades from unicolorous brown-black to such having 
the distal margins green and blue, and, moreover, we find among them all transitions from quite plain, unmar¬ 
ked specimens to those with white-banded wings. From a large collection of specimens made on Kina Balu 
by Waterstradt within comparatively short time this variability appears to be individual rather than seaso¬ 
nal. Only it must be observed that the rich blue and green specimens came almost exclusively from the higher 
mountains, whereas the uniformly dark specimens are found both in the mountains and the low-lands, bipunctata 
Voll. (128 b) was based upon the darkest form which, although rather scarce, is widely distributed, displaying 
the same dusky brown-black colouring, whether it occurs in the alluvial plains of the South or in the moun¬ 
tains of the North. Some specimens are quite brown, whereas others are thinly scaled with green, and still 
others show the beginnings of white bands, such specimens approaching obsolescens Fruhst. from Lombok,

helmet-shaped median spots. — Cordelia Fruhst. (128 b) refers to a form with green-margined hindwings, cordelia.
