Fam. Termitida. 
Termes, Linn. 
T. tenuis, Hagen. — White Ants, as they are called, were intro- 
duced into the Island, in the year 1840, in some timber from 
a slave-ship captured by H.M. cruisers on the West Coast of 
Africa, and sent to St. Helena for adjudication. The identical spot 
where this timber was deposited in the town is pointed out to this 
day, the whole population of the place having good reason to 
remember the surreptitious entrance into their camp of an enemy 
such as Termites have proved. The species was supposed to be of 
African origin, until, three years ago, I brought some specimens to 
England, and, through the kindness of Mr. H. W. Bates, it 
was identified by Mr. M ‘Lachlan as one peculiar to tropical 
America : as many of the slavers were Brazilian vessels, it is easy to 
understand how both timber and Termites originally came from 
that quarter. After their appearance in the town, a quarter of a 
century passed by without much evidence of the tenible work of 
destruction in which they were engaged. It was known that they 
were eating books, furniture, papers, and clothes, with occasionally a 
beam or two in the houses, but no one entertained the idea that in 
an additional five or six years their houses would be in ruins and an 
expenditure of 60,000/. at least imperatively necessary to recon- 
struct them. Such, however, has happened. Public and private 
interests have alike suffered to a large extent, and the whole 
colony has been taxed beyond its powers merely to replace what a 
few years before it possessed. 
It was a melancholy sight five years ago to see the town, which 
had hitherto not been without its claims for admiration, devastated as
