Himalayas and of India. 



species of true Carabus, only one of which I was enabled to describe. 

 Several may occur in the colder mountain temperature, and it is probable 

 they will resemble Siberian forms. Wherever the oak grows, there Ca- 

 losoma will be found. Seven eastern species are known to me. C. indi- 

 cum inhabits Nepal. If caterpillars are necessary to keep iu check the 

 luxuriance of tropical vegetation, surely the Calosomata are equally ne- 

 cessary to keep within bounds these Insects, which sometimes destroy, 

 in northern climes, nearly the foliage of the year. 



NEBRIADiE. 



This family may be considered as belonging to a Northern and Alpine 

 range. Should it occur in Nepal, it will be found at a considerable ele- 

 vation, possibly amid the Himalayan snows. As to Elaphrus, I have 

 already stated an opinion that Catascopus represents it in India. 



BEMBIDIIDiE and TRECHID.^:. 



Of the former famil}^, several genera will no doubt eventually be found 

 in Nepal : a single species of Tachys is the only example I am able to re- 

 cord at present. Of the latter, Stenolophus, Acupalpus and Tetragcno- 

 derus have occurred : th^ last of which may take the place of Bembi- 

 dium. 



DYTICIDiE. 



Aquatic Coleoptera are apparently not much influenced by climate : 

 the temperature of water not varying like that of the earth or air, is the 

 reason we meet with the self-same species in the interior of India and 

 the south of France. Dyticus appears confined to Northern Europe or 

 America, while Cybister is dispersed throughout the world. Eunectes 

 and Hydaitcus belong to Nepal and India, and to the latter country we 

 may add also the following genera, viz. Colymbetes, Lacccphilus, Noterus, 

 Hyphydrus and Hydroporus. 



GYRINIDiE. 



Many gigantic species of Gyrinidae abound in India. Dineutus ne- 

 palensis, politus, and spinosus, have been found within the Himalayan 

 districts. 



HYDROPHILID^. 



Several genera of this family are as widely distributed as the Dyticidse ; 

 and most of those found in India inhabit Nepal. 



NECROPHAGA. 

 Differing with most entomologists, I am inclined to believe that the 

 earrion feeders abound mor» in warm countries than is generally believed.
