From the above it is clear that Stal's genus Scudderia must fall 

 as a synonym of Phaneroptera Serville, having the same genotype 

 and being more recent by almost two decades. This leaves the 

 species listed under Phaneroptera by Kirby* (except attenuata Walk., 

 marginalis Brunn., and annulata Brunn., as noted below) without 

 valid generic assignment. For these species and grandis, nakoensis 

 and tympanalis M. &. S., I propose the new generic name Anerota, 

 with Gryllus falcatus Poda as the designated genotype. 

 The synonymy is as follows: 



Anerota Caudell, nom. nov. 

 Phaneroptera Brunner (not Serville), Monogr. Phaneropt. 23, 209. 1878. 

 Phaneroptera Kirby (not Serville), Syn. Cat. Orth. 2: 424. 1906. 



The writer sincerely regrets these changes, the sinking of an old 

 and well-known American genus and the introduction of a new generic 

 name to replace an older one. However, such acts, being based on 

 sound nomenclatorial grounds, are necessary if we attempt to comply 

 with codified rules. And, as therein lies our only hope for an ulti- 

 mately stable nomenclature, the sooner such changes are wrought 

 the better. 



The type of Phaneroptera attenuata Walker is in the British Museum, 

 where it was studied by the writer in 1913. It is a female in poor 

 condition, the abdomen being missing and the rest of the insect glued 

 on a card. Most of the parts used in classification were, however, 

 well preserved and prove that the species was wrongly placed by 

 Walker and Kirby. It has conchate foramina and belongs to the 

 genus Tylopsis, where it is a synonym of the older species T. hilin- 

 eolata Serville. Phaneroptera marginalis Brunn. was described from 

 an imperfect female, the anterior and intermediate legs being wanting. 

 Kirby assumed the character of the missing parts to be the same as in 

 Walker's attenuata and so synonymized it under that species. It 

 seems probable that in this Kirby was correct, and the synonymy is 

 as follows : 



Tylopsis bilineolaris Serville, Orth., p. 419. 1839. 



Phaneroptera attenuata Walker, Cat. Derm. Salt. Brit. Mus. 2:338. 

 1869. 



-Phaneroptera marginalis Brunner, Monogr. Phaneropt. 210, 214. 



1878.
