On Some Delphacidae from South India (Homoptera). 



BY F. MUIR. 



Through the kindness of Mr. E. A. Butler I have received 

 a small but interesting- collection of Delphacidae made by Dr. 

 T. V. Campbell in British India. It consists of eight genera 

 and ten species, one genus and four species of which I con- 

 sider as new. Columhisoga camphclli was taken at an eleva- 

 tion of 8000 feet in South India, and its nearest ally is known 

 from 10,500 feet in Columbia, South America. 



My thanks are due to Dr. Campbell and Mr. Butler for the 

 collection. 



Aleasurements are from the apex of vertex to apex of abdo- 

 men, and from the base to apex of one tegmen. The types have 

 been deposited in the collection of the Hawaiian Sugar Planters' 

 Experiment Station, Honolulu.

As the genus Tropidocephala stands at present I am unable 

 to separate it from Orchesma. Distant (1916 t. c. p. 465) uses
