THE ENTOMOLOGIST. 



the temperate regions of the Himalayas ; but to them he does not 

 appear yet to have given a name. 



The author of the present note invites a suggestion from 

 students of the Hemiptera, for some suitable name to be given to 

 the large number of Trimerous insects which do not stridulate, 

 and which are neither Aphides nor Coccidee, nor members of any 

 of the families usually comprehended in the Hemiptera-Hoaio- 

 ptera. Burmeister, Fieber, Sahlbeig, Walker and Edwards, 

 have all shown a connection between the extremes of Cicadetta 

 and Typhlocyba, for these writers group the genera under the 

 head Cicadina. An equivalent of " les Muettes " of Latreille, 

 which will range with the Stridulantia of Burmeister, is wanted. 

 Tentatively the term "Silentia" is offered, and for the whole 

 family the term '* Tettigiidse," which will range with Apliididse 

 and Coccidse. 



Such a scheme would perhaps meet the views of those who 

 consider that the possession of sounding organs with opercular 

 scales in the males alone, is of sufficient import to sharply divide 

 our only known British species from the Cercopidse and Jassidse, 

 which have them not. 



The annexed sketch, which is partially filled in, will show the 

 position taken by the Cicadas amongst other Rhynchota. 



The word Cicadse is here used as a plural to the English 

 word Cicada.
