ies from one to the other. Among the
_Pyralites, Hymenia recurvalis_ inhabits also the West Indies, South
America, West Africa, Hindostan, China, Australasia, Australia, and New
Zealand; and its food-plant is probably some vegetable which is
cultivated in all those regions; so also _Desmia afflictalis_ is found
in Sierra Leone, Ceylon, and China.

Order DIPTERA.

"About fifty species were observed by Dr. Templeton, but most of those
here recorded were collected by Mr. Thwaites at Kandy, and have a great
likeness to North European species.

"The mosquitoes are very annoying on account of their numbers, as might
be expected from the moisture and heat of the climate. _Culex laniger_
is the coast species, and the other kinds here mentioned are from Kandy.
Humboldt observed that in some parts of South America each stream had
its peculiar mosquitoes, and it yet remains to be seen whether the gnats
in Ceylon are also thus restricted in their habitation. The genera
_Sciara, Cecidomyia_, and _Simulium_, which abound so exceedingly in
temperate countries, have each one representative species in the
collection made by Mr. Thwaites. Thus an almost new field remains for
the Entomologist in the study of the yet unknown Singhalese Diptera,
which must be very numerous.

Order HEMIPTERA.

"The species of this order in the list are too few and too similar to
those of Hindustan to need any particular mention. _Lecanium coffeoe_
may be noticed, on account of its infesting the coffee plant, as its
name indicates, and the ravages of other species of the genus will be
remembered, from the fact that one of them, in other regions, has put a
stop to the cultivation of the orange as an article of commerce.

"In conclusion, it may be observed that the species of insects in Ceylon
may be estimated as exceeding 10,000 in number, of which about 2,000 are
enumerated in this volume.

Class ARACHNIDA.

"Four or five species of spiders, of which the specimens cannot be
satisfactorily described; one _Ixodes_ and one _Chelifer_ have been
forwarded to England from Ceylon by Mr. Thwaites."

since Sir J.E. Tennent's departure from the Island in 1849.
