insects of these two families in North Europe ; in the Scyd- 
mcenidce, Ptiliadce, Phalacridce, Nitidulidce, Colydiadce, and 
Latliridiadoe the northern form is still more striking, and 
strongly contrasts with the tropical forms of the gigantic 
Copridce, Buprestidce, and Cerambycidw, and with the Ela- 
teridce, Lampyridce, Tenebrionidce, Helopidce, Meloidm, Curcu- 
lionidce, Prwnidce, Cera?nbycidce, Lamiidce, and Endomychidce. 
" The Copridce, Dynastidce, Melolonthidce, Cetoniadce, and 
Passalidce are well represented on the plains and on the coast, 
and the species are mostly of a tropical character. 
" The Hydrophilidce have a more northern aspect, as is gene- 
rally the case with aquatic species. 
" The order Strepsiptera is here considered as belonging to 
the Mordellidce, and is represented by the genus Myrmecolax, 
which is peculiar, as yet, to Ceylon. 
" In the Curculionidce the single species of Apion will recall 
to mind the great abundance of that genus in North Europe. 
" The Prionidce and the two following families have been 
investigated by Mr. Pascoe, and the Hispidce, with the five 
following families, by Mr. Baly ; these two gentlemen are well 
acquainted with the above tribes of beetles, and kindly supplied 
me with the names of the Ceylon species. 
Order Oethopteka. 
" These insects in Ceylon have mostly a tropical aspect. 
The Physcqjoda, which will probably be soon incorporated 
with them, are likely to be numerous, though only one species 
has as yet been noticed. 
Order Neuropteka. 
" The list here given is chiefly taken from the catalogue pub- 
lished by Dr. Hagen, and containing descriptions of the species 
named by him or by M. Nietner. They were found in the 
most elevated parts of the island, near Eangbodde, and Dr. 
Hagen informs me that not less than 500 species have been 
noticed in Ceylon, but that they are not yet recorded, with
