OENEEAL SUMMARY. 193 



Dry meadows {Praia arida.). Eupelix ciispidata, 

 Megophthalmus scanicus. 



Heaths (Ericeta). Asiraca clavicornis, Vlopa reticulata, 

 Stiroma hicarinata. 



Sahlberg adds to these habitats : — Luci, Lacus, 

 Campi, Saliceta, Cidta, and Loci idiginosi. 



Other habitats I iiave noted in the diagnosis of 

 species. 



As to distribution of the Tettigid^, fossil forms 

 show that formerly the family extended over wide 

 ranges of the earth's surface. Although our notices are 

 very scanty as to the distribution of recent forms, they 

 are obviously scattered over the continents of Europe, 

 India and China, Africa and North America. Extra- 

 ordinary forms of Centrotidse and other subfamilies of 

 Membracidae are met with in Mexico ; but they yet 

 want describers. 



At present we do not know much more than the 

 fact that at Simla and on the slopes of the Himalayas, 

 where the oak, the chestnut, walnut, beech, ilex, 

 conifers, and other trees of semitropical growth flourish, 

 stridulating Cicadse are common, and, doubtless, many 

 other divisions of the same group may be found. The 

 singing sorts are few on the plains, but they appear in 

 the hills about July, and continue their din more or less 

 for four months, and then they somewhat suddenly 

 disappear. 



The Rev. F. A. Walker made some interesting 

 captures of Triecphora sanguinolenta at Aceldama in 

 April, and at Ephesus in Asia Minor in May, 1886.* 



The Tibiceninae, Cicadinae, Membracinse, and Ful- 

 gorinse are in great measure confined to hot climates ; 

 but the Cercopinse and Jassinse seem to be almost 

 everywhere present. In Great Britain we have no 

 recorded examples of the Lystridae, Derbidae, and 

 Flatidae. 



By far the larger number of British Tettigidae occur 

 during the summer and autumn months, but some
