On ih<> Entomology of the 



[July 



native of the Tropics : the specimens, however, are mere dwarfs, compar- 

 ed With those of Feiiinsular India, a iact which may be regarded as a proof, 

 that Anthia has here reached its extreme limits, and consequently will 

 soon disappear (as is the case) and be represented by another type, 

 fuhilliog the same fmictions, only under a difference of form. The follow- 

 ing genera of Himalayan Insects, selected from many others, will evince 

 their tropical relationship. Among the Cicindelidae, CoUiuris appears ; 

 among the Carabidae, we find Desera, Omphra, and Cyclosomus ; among 

 the Lamellicornes, Euchlora, Mimela, and Dicronocephalus ;^and to these 

 may be added, Anisotelus belonging to Telephoridae, and Podontia 

 and Phj'Uocharis to the Chrysomelidae : all of them attached to warm 

 countries, and some, indeed, are seldom found but within the Torrid 

 Zone. It is needless to state many genera from the Himalayas evinc- 

 ing an affinity to European types ;* some few, however, are worth 

 noticing, such as Broschus and true Carabus, Geotrupea and Pi- 

 melia : the two last have been declared by high authority never 

 to be found in India. Regarding identity of Insects occurring in 

 the Himalayas, as well as in Europe, there are several species of the 

 foil 'wing genera of Coleoptera, namely, Elater, Melolontha, Chry- 

 soiTiela, Cassida, and Coccinella, which I cannot help thinking are the 

 sanie as those of England ; particularly as the vegetation of the two 

 countries greatly coincide, for in very many cases, genera, and in some 

 instances the self-same species of plants have been recognized. Among 

 the carnivorous Insects, I believe that Dermestes lardarius, and vulpinus, 

 Coryn^tes violaceus, and rufipes, and some of the Staphilinidae, are 

 essentially the same in Europe and the Himalayas. Of Lepidoptera, I 

 figure Papilio Machaon, because it is evidently the same as what we meet 

 with in England ; the same remark will apply to Vanessa Atalanta, and 

 Cyifthia Cardui. The French entomologists are inclined to regard the 

 Insects of widely separated countries as distinct species ; I wish to esteem 

 them as varieties, and I cannot help thinking, that as identity of Plants 

 has been satisfactorily proved by Dr. Royle, so also we may believe in 

 the identity of Insects in regions widely removed from each other. At 

 any rate, should these varieties eventually prove distinct (which may be 

 ascertained, I think, in the Lepidoptera order, when we become better 

 acquainted with the oval, larval, and chrysalidous stages), yet the 



• I may here add, that various Himalayaa genera closely approximate Siberian forms, 

 and that some of the species described by Dr. Gebler from the Altaic chain of moun- 

 tains, particularly some Cbrysomelidae, I believe to be indigenous ia both regions.
