444 INSECTS. [Cuap. XII. 
insects of these two families in North Europe; in the Scyd- 
menide, Ptiliade, Phalacride, Nitidulide, Colydiade, and 
Lathridiade the northern form is still more striking, and 
strongly contrasts with the tropical forms of the gigantic 
Copride, Buprestide, and Cerambycide, and with the Ela- 
teride, Lampyride, Tenebrionide, Helopide, Meloide, Curcu- 
lionide, Prionide, Cerambycide, Lamiide, and Endomychide. 
‘The Copride, Dynastide, Melolonthida, Cetoniade, and 
Passalide are well represented on the plains and on the coast, 
and the species are mostly of a tropical character. 
“ The Hydrophilide have a more northern aspect, as is gene~ 
rally the case with aquatic species. 
“ The order Strepsiptera is here considered as belonging to 
the Mordellide, and is represented by the genus Myrmecolax, 
which is peculiar, as yet, to Ceylon. 
“ In the Curculionide the single species of Apion will recall 
to mind the great abundance of that genus in North Europe. 
“ The Prionide and the two following families have been 
investigated by Mr. Pascoe, and the Hispide, 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 ORTHOPTERA. 
“ These insects in Ceylon have mostly a tropical aspect. 
The Physapoda, which will probably be soon incorporated 
with them, are likely to be numerous, though only one species 
has as yet been noticed. 
Order NEUROPTERA. 
“ 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 Rangbodde, and Dr. 
Hagen informs me that not less than 500 species have been 
noticed in Ceylon, but that they are not yet recorded, with
