L. cossaea. This species, being beside L. haraldus the most beautiful of the genus, was at first recognized 
by Distant and already figured (Rhop. Malayana 1886, t. 54 fig. 10). As Distant took the y of the species 
to be a $, he still did not dare to denominate it for fear it might be the $ of a Lycaenopsis already known. 
About 10 years later the species was discovered by Martin in Sumatra, by Waterstradt in Borneo and by 
myself in Java at the same time. Staudinger denominated it plauta i. 1., which name was published by Druce 
in 1895. In the same year also de Niceville described it as cossaea according to Martin’s and my specimens. 
Who has the priority in naming it is not ascertained, but let us follow de Niceville’s example. In 
contrast with the prominent size and beauty of the imagines are the most primitive and also stunted clasping- 
organs which, however, are distinguished by uncommonly long bristles and the entire absence of distal spines.

border of the forewing. Nias. — sabatina Fruhst. I only found in West Java, and the beautiful figures in sabatina. 
Pieper’s magnificent work are made according to my specimens. The y appears in two forms. There are two 
y forms: one with a whitish costal area on the hindwing above, as Niceville figured it, and a plain, blue form 
figured by Piepers according to specimens of my collection. The extremely rare $ is above more extensively 
suffused with blue than $$ from Sumatra. — sonchus Drc., described as a distinct species according to a y, sonchus.

the Malayan Peninsula and differs from plauta Drc. (154 b) by the more prominent black bordering of both 
wings in the yy. From Moulton’s description of the y we see that the $ is much more closely allied to the 
$ of cossaea from Sumatra than to the $$ of plauta from North Borneo being abundantly covered with white. — D'.JZ

smaller punctiform spots. 
L. transpectus. An anatomically quite isolated species, recognizable by the heavy, distally very 
broad and rounded valves, without a terminal tooth, but with one or two dorsal spikes in the centre of the 
lamella. The uncus exhibits a peculiar, ventral, thumb-like appendage. The imagines are characterized 
by pointed forewings, with an extremely broad black apical margin which is continued on the hindwings in 
the yy of the rainy period. Only two areal races: transpectus Mr. (152 e, f) with forma latimargo Mr. of the transpectus. .

in Vol. I, t. 83 f, excellently fits, particularly by the dotting on the hinclwing beneath, to the $ of L. transpectus 
from Sikkim, lying before me, which represents the $ exhibiting the purest and most extensive white among 
all the Lycaenopsis. 
L. matanga Chapm. (= clelapra Moult.) (153 f,g). This novelty, being anatomically evidenced matanga. 
by Chapman, has the contours of wings like L. transpectus (152 e, f) and a similar distribution of the white 
patches above. The cell of the forewing is remarkably darkened. The clasping-organs approach those of L. 
albocoeruleus , but without showing a real alliance to this species, which is already impossible on account of 
the roundish, hemispherical uncus. The valve remains more slender and terminates into a point bent up up¬ 
wards. Certainly L. matanga belongs to a species quite isolated for the present, and its position among the 
great number of species of the Lycaenopsis is only ascertainable by the figure of the clasping-organs. 
L. chelaka Moult. (153 f) is a rare species from Sarawak. chelaka. 
L. moultoni Chapm. (153 f). y above with about the same broad black border of the wings as in moultoni. 
L. transpectus forma latimargo Mr., but above, according to statements by its author, with the lustrous ground¬ 
colour of Jamides bochus. Clasping-organs somewhat like in L. cossaea Nic., the valve, however, towards the 
base a little more slender, before the end provided with just as long bristles as L. cossaea and plauta. Uncus 
apparently somewhat rounder than in plauta. L. moultoni is, however, by far inferior in size to L. cossaea, and 
the marking above is quite different, so that also in this entirely isolated species, hitherto peculiar of Borneo 
we cannot think of an affinity with Lycaenopsis having been discovered to this day.
