L. de Niceville & Dr. L. Martin —Butterflies of Sumatra. [No. 3, 
same time we may we think point with some little pride to the fact that 
it is far larger than any local list which has ever been published except 
for certain places in Central and South America, containing as it does some 
756 species. Next to it probably in size is de Niceville’s “ A List of the 
Butterflies of Sikliim ” in the Gazetteer of Sikliim (1894), in which 63J 
species are enumerated. Synonomy for the commoner and better known 
species has not been given; but all references to figures of species from 
Sumatra and lately described species, as well as synonyms of recent 
date have as far as known been entered. 
The imperfections of this list are doubtless many, but we would 
ask our adverse critics to remember the disadvantages of working in 
a tropical climate, and also the many letters that have to be written, 
the number of books to be consulted, the many collectors to be 
“ caught,” trained, supplied with necessaries and depatclied to the collect¬ 
ing grounds, and the time occupied in preparing and conserving the 
specimens when obtained, before a list similar to this one can be pre¬ 
sented to, let us hope, an indulgent public.

Grose Smith. Butler. Staudinger. Distant. Moore as reinwardti and 
druyri. A common species, occurring from the lower slopes of the moun¬ 
tains to the sea. As usual it is very variable, two of these varieties 
have been described by Moore as distinct species occurring in Sumatra. 
The dark variety figured by Distant in Rhop. Malay., pi. i, fig. 2, 
only comes from places near the mountains and the outer slopes where 
the rainfall is far heavier than in the plains, while the lighter specimens 
are found in the forests of the alluvial plain, but the two forms gradually 
merge the one into the other, and no distinguishing line can be drawn 
between them. Specimens of the genus Hestia are nearly always seen 
in pairs, and are very fond of flying over the small streams so common 
in our forests. They never leave the high forest, probably because 
they have a very weak flight, and their enormous tissue-paper-like 
wings cannot withstand the wind away from the shelter of the trees.
