SOME NECESSARY CHANGES AND CORRECTIONS IN NAMES 



OF ORTHOPTERA. 



by james a. g. rehn, philadelphia, pa. 



Mantid^e. 

 Miomantis, Saussure. Bull. Ent. Suisse, III., p. 64, 1870. 



Preoccupied by Miomantis, Blanchard. D'Orbigny, Voy. Anier. 

 Merid., VI., Ins., p. 209, 1842 (Coleoptera). To fill the deficiency, I 

 propose the name Calidomantis. 



Harpax, Serville. Ann. Sci. Nat., XXII., p. 45, 49, 1831. 



Preoccupied by Harpax, Parkinson. Organic Rem., 181 1 (Mollusca). 

 I have not been able to examine the first edition of Parkinson, but in the 

 second the name Harpax occurs on page 221 of volume III. To replace 

 Serville's genus, I propose the name Anstralomantis. 



Phasmid/e. 

 Phantasis, Saussure. Miss. Scient. Mex. Orth., p. iSS, 1872. 



Preoccupied by Phantasis, Thorns. Essai Classif. Cerambyc, p 25, 

 i860 (Coleoptera). The name Hesperophasma is proposed to fill the 

 deficiency. 



ACRIDIDjE. 



Akentetus, McNeill. Proc. Davenp. Acad., VI., p. 225, 1897. 



This generic name has been emended to Acentetus (Scudder, Proc. 

 Arner. Acad. Arts Sci., XXXV., p. 45, 1899), in which case it is 

 preoccupied by Acentetus, Cabanis (Mus. Hein., IV., pt. 1, p. 102, 1862), 

 in Ornithology. This instance should help to deter the lovers of emenda- 

 tion and purity, the inviolability of the name being the easiest and most 

 satisfactory method in this as well as all cases where ^.typographical txxox 

 is not evident. 



Alpha, Brunner. Ann. Mus. Cio. Stor. Nat, Genova, XXXIII., p. 121, 

 1893. 



Preoccupied by Alpha, Saussure. Smith. Misc. Coll., XIV., p. 121, 

 1875 (Hymenoptera). In allusion to the habitat of some of the species, 

 I propose the name Cordillacris. 



The genus Beta of Brunner (p. 121) is also antedated in the same 

 way (Misc. Coll., XIV., p. 88), but as his name has no type or included 

 species designated, it cannot be regarded as thoroughly established. 



Ichthydion, Saussure. Revue et Mag. deZool., p. 390, 1859. 



Preoccupied by Ichthydion, Dejean. Catal. Coleopt., II., 1833 

 (Coleoptera). In the third edition of Dejean, the name is found on page 

 13. To replace the preoccupied name, I propose the term Ichthyotettix.
