270 ZOOLOGY. [PART II. 



yet almost unknown, but will probably be found to have more 

 resemblance to that of Ceylon than to the insects of northern 

 and western India just as the insect-faima 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 Hindustan 

 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 Neilgherry 

 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 pro- 

 bably 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 Ma- 

 labar, their insect-fauna will probably also resemble that of the 

 latter region. 



" The insects mentioned in the following list are thus dis- 

 tributed : 



Order COLEOPTEEA. 



" The recorded species of Cicindelidee 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 Stapkyli/n&dcB, es- 

 pecially those collected by Mr. Thwaites, near Kandy, and by 

 M. Nietner at Colombo, have much resemblance to the insects 

 of these two families in North Europe; in the Scydmcenidcc, 

 Ptiliadce, PJialacrida;, Nitidu Udce, Colydiadcv, and Lathridiadte 

 the northern form is still more striking, and strongly contrasts
