120 THE CANADIAN ENTOMOLOGIST. 



bipunctatus = Tetrix, Latreille, 1804. 



subulatus = Tetrix, Latreille, 1804. 



As will be seen from the above, serratus is the type of Bulla, it 

 being the last one removed. 



Ac H ETA. 

 — gryllotalpa = Gryllotalpa, Latreille, 1804. 



— domesticus. 



— campestris = Liogry 'litis, Saussure, 1877. 



— umbraculatus = Platyblemmus, Serville, 1839. 



In this and the succeeding classic genera, the non-exotic species are 

 preceded by a dash. The type of Acheta (and accordingly of Gryllus) 

 will be seen to be domesticus. As a name once used cannot be can- 

 celled, the last eliminated species (aside from the type of Gryllus) must 

 be considered as the type of Acheta, the result being that Liogry llus is a 

 synonym of Acheta. 



Acrida. 

 nasutus. 

 turritus. 

 The diversity of opinion regarding the use of the name Acrida is 

 certainly rather singular. Mr. Scudder (Psyche VIII., p. 168) has given 

 us his opinion on the subject, but some parts of it are rather misleading. 

 The genus Acrida of Linnaeus, as shown above, was based on nasutus and 

 turritus. Fabricius included both of these species and also brevicomis in 

 his genus Tryxalis, the result being that brevicomis is the type of 

 Tryxalis, the other two species being the basis of Acrida. Brunner's 

 genus Metaleptea is thus a synonym of Tryxalis, but not because of Stal's 

 restriction as Scudder argues. The work of Stal was the logical out- 

 come of a study of the original genera involved. 



Tettigonia. 



citrifolius = Posidippus, Stal, 1874. 



laurifolius = Microcentrum, Scudder, 1862. 



myrtifolius = Ctenophlebia, Stal, 1873. 



elougatus = Mecopoda, Serville, 1831. 



lamellatus = Mecopoda, Serville, 1831. 



ocellatus = Pterochroza, Serville, 1831. 



acuminatus = Oxyprora, Stal, 1873. 



triops = Cotwcephalus, Thunberg, 1S15.
