CHAP, v.] CLASSIFICATION. 103 



The number of species of Butterflies is about the same as that 

 of Birds, while the six families of Coleoptera selected, comprise 

 more than twenty thousand species, far exceeding the number of 

 all other vertebrates. These families have all been recently cata- 

 logued, so that we have very complete information as to their 

 arrangement and distribution. 



LEPIDOPTERA DITJRNA, OR BUTTERFLIES. 



Fam. Fam. 



1. Danaidse. 9. Libytheeidce. 



2. iSalyridfB. 10. Nemeobiida?. 



3. Elyuiniidfe. 11. Eurygonidee. 



4. Morpbidse. 12. Erycinidse. 



5. Brassolidae. 13. Lyca?iiidae. 



6. Acrseidfe. 14. Pieridse. 



7. HeliconidBe. 15. Papilionidse. 



8. Nymphalidse. 10. Hesperidse. 



COLEOPTERA, OR BEETLES. 



Fam. Fam. 



1. Cicindelidae ... Tiger-beetles. 4. Cetoniidse ... Rose-chafers. 



2. Carabidte ... Gronnd-beetles. 5. Buprestidse . . . Metallic Beetles. 



3. Lucanidse . . . Stag-beetles. 6. Longicornia . . . Long-horned Beetles. 



The above families comprise the extensive series of ground 

 beetles (Carabidffi) containing about 9,000 species, and the Longi- 

 corns, which are nearly as numerous and surpass them in variety 

 of form and colour as well as in beauty. The Cetoniidas and 

 Buprestidie are among the largest and most brilliant of beetles ; 

 the Lucanidfe are pre-eminent for remarkable form, and the 

 CicindelidcTe for elegance ; and all the families are especial 

 favourites with entomologists, so that the whole earth has been 

 ransacked to procure fresh species. 



Eesults deduced from a study of tliese will, therefore, fairly 

 represent the phenomena of distribution of Coleoptera, and, 

 as they are very varied in their habits, perhaps of insects in 

 general.
