INSECTS. 



[Chap. XII. 



insects of these two families in North Europe ; in the Scyd- 

 mcenidce, Ptiliadce, Phalacridce, Nitidulidce, Colydiadce, and 

 Lathridiadoe the northern form is still more striking, and 

 strongly contrasts with the tropical forms of the gigantic 

 Copridce, Buprestidce, and Cerambycidce, and with the Ela- 

 teridce, Lampyndce, Tenebrionidce, Helopidce, Meloidce, Curcu- 

 lionidce, Prionidce, Cerambycidce, Lamiidce, and Endomychidce. 



" The Copridcej 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 MyrmecolaXj 

 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 ffispidce, 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 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
