northern and western India — just as the insect-fauna of 
Malaya appears more to resemble the similar productions of 
Australasia than those of the more northern continent. 
" Mr. Layard's collection was partly formed in the dry 
northern province of Ceylon; and among them more Hin- 
dustan insects are to be observed than among those collected 
by Dr. Templeton, and found wholly in the district between 
Colombo and Kandy. According to this view the faunas of 
the Nilgherry Mountains, of Central Ceylon, of the peninsula 
of Malacca, and of Australasia would be found to form one 
group;— while those of Northern Ceylon, of the western 
Dekkan, and of the level parts of Central Hindustan would 
form another of more recent origin. The insect-fauna of the 
Carnatic is also probably similar to that of the lowlands of 
Ceylon ; but it is still unexplored. The regions of Hindustan 
in which species have been chiefly collected, such as Bengal, 
Silhet, and the Punjaub, are at the distance of from 1300 to 
1600 miles from Ceylon, and therefore the insects of the latter 
are fully as different from those of the above regions as they 
are from those of Australasia, to which Ceylon is as near in 
point of distance, and agrees more with regard to latitude. 
" Dr.Hagen has remarked that he believes the fauna of the 
mountains of Ceylon to be quite different from that of the 
plains and of the shores. The south and west districts have a 
very moist climate, and as their vegetation is like that of 
Malabar, their insect-fauna will probably also resemble that of 
the latter region. 
" The insects mentioned in the following list are thus dis- 
tributed : — 
u Order Coleoptera. 
" The recorded species of Cicindelidce inhabit the plains or 
the coast country of Ceylon, and several of them are also 
found in Hindustan. 
" Many of the species of Carabidce and of Staphylinidce, 
especially those collected by Mr. Thwaites, near Kandy, and 
by M. Nietner at Colombo, have much resemblance to the
