resentative 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 coffeae_ 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 2000 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."
