ON THE NOMRNCLVTCRK OF THE ORTHOPTERA. 329 



stmnamensis, by a sort of elimination, is by this time the type of 

 Blatta, which jrenus, therefore, corresponds with Branner's Leucnphaca. 

 The genus PlinUodmnila, which de Saussure suppresses as being 

 synonymous with Blatta, is thus restored with its type P. (jermanica. 

 So that, owing to Latreille, in 1825 and 1829, taking B. orirHtalls as 

 the type of his new genus Kakrtiac, this barbarous name must now 

 supplant Blatta for the familiar on'cutalis. Sti/Iopi/(ia is, of course, a 

 synonym of Kakerlac. Kirby, in 1891, refers to Kakerlac (proposed 

 for B. oricntalis and allies) and Stelfopi/i/a (includes Blatta oriinitalii^, 

 &c.), as synonyms of Blatta ; the difference between the arguments of 

 Kirby and Krauss is this, Kirby regards oriental^ as the type of 

 Linne's genus Blatta, in which case it is permanent, but Krauss 

 maintains that Latreille first fixed the type in making orientalis the 

 type of his new genus Kakerlac. 



The Mantidae are not affected, Mantis rdi(/insa remaining the type 

 species of the typical genus ; Phaama phtliimnni (Linn., 1858), which 

 is more familiar under the name Phanma necydaloulc>;, Linn. (1863), is 

 the type of Phasma. 



But confusion reigns supreme in the Saltatoria. Brunner's names, 

 which were based rather upon use and convenience than upon the 

 strict law of priority, have been freely used owing to the immense and 

 far-reaching influence of his Prod ramus that appeared twenty years 

 ago ; but many writers, including Bolivar, Kirby and Karsch, have 

 shown their independence. Krauss divides the Saltatoria into three 

 families ; the first is Locastidae ( = Acridiodea of Brunner) , which is again 

 subdivided. The familiar Acridiiun aeriyptiacuin, Linn., gives way 

 before Locusta tatarica, Linn., so that the Arriiliidae become the 

 subfamily Lociistinae. Many entomologists will welcome this change. 

 The Trii.validae of Brunner form the subfamily Acridiiiiae, with the 

 genus Acrida, as has been adopted by many recent authors, including 

 myself in a recent monograph. Krauss courageously rejects Tctti.c and 

 Tetrix, which have no claim by priority, confirming the opinion of 

 Kirkaldy {Entow., 1901, p. 243). Fabricius' Arnjdiinn must be 

 restored, but here we meet with another difficulty. As we have already 

 a siibfamily Acridiinac, it would be pedantic to force the Law of 

 Priority to its furthest extreme and so have Acri/diinat' as well ; 

 Tettitiidae, and Tetri<iidae must be rejected ; Krauss suggests the name 

 Paratettiifinae, from Bolivar's genus r*aratettix. Brunner's Locustodca 

 become Tetti(ioniidae, though Kirby and Karsch prefer Pliasf/onuridae. 

 Krauss restored Tetti<ionia, its type species being T. acuminata, a 

 Brazilian form, but it is not quite clear whether he retains Plias/ianura, 

 Westw., for T. viridissima, or ranges it in Conocephalus ; if he does, 

 the latter must entirely alter its significance. 



The crickets become Aclietidac, a change that will be welcome to 

 many. The genus (Tryllus remains, not for our old friend the Cricket 

 of the Hearth, but for an exotic Central and South American form, 

 Gryllus inuticus, Geer. The House and Field Cricket are thus 

 permitted to take back their old-fashioned names of Acheta. (rriillo- 

 talpa remains untouched, although Kirby prefers Oken's Curtilla. 



Many entomologists will probably be disgusted to find names that 

 are in general use thus submitted to a searching examination ; those 

 that cannot prove their right to existence must go, and the only 

 difficulty is that most authors have slightly different ideas as to the
