130 BRITISH CICADvE. 



or infesting, the rosemary (Bosmarimifi), which is also a 

 Labiate plant. The Kev. T. A. Marshall pointed out 

 the fact that the males of E. melissce show no black 

 spot on the hinder tarsi. Though this is a trivial 

 character, it may help to separate the species from 

 E. stachydearum, which has no spot. 



Dr. Sahlberg does not include E. melissce in his 

 ' Ofversigt af. Cicadariae.'

Genus XLVIII.— TYPHLOCYBA, Gennar.* 



Body linear and cylindrical. Vertex more or less 

 pointed. Elytra much longer than the body, without 

 a limbal flap, and with four well-defined apical areas. 

 Wings show the first and second nervures meeting 

 before the apex, and continuing, as a single nervure, 

 to the margin. Third nervure simple, continued to the 

 margin, but connected to the second by a short trans- 

 verse vein. Fourth nervure connected with the third 

 by another transverse vein. 



This genus is equivalent to Anomia of Fieber. The 

 species are mostly arboreal in their habits. 



* It would much assist the memory if those who give names to the new 

 genera they construct would, at the same time, state the derivatives of 

 the terms they employ, if they intend them to he distinctive. It seems 

 hopeless to assign meanings to such words as Isstis, Lihiirnia, Asiraca, 

 Leclra, and many others. Possibly such names never had meanings, but 

 wei'e meant to act as mere signs. It has been even said that in some 

 cases the first syllables of any three words first meeting the eye in 

 a lexicon have been cleverly jumbled together, so as to give the whole a 

 classical appearance. The word Typlilocyha may have reference to the 

 obscurely cubical forms of the head or the prothorax in some species.
