Re-port on a Collection of African Locustidx. 91 



1829. Xyijhiccra, Latreille, Cuvier, Regne Anim, (ed. 2), v, 

 p. 186. 



Types, Gryllus carinatus, Linn., and G. gallinaccus, Fabr. 



1831. Xiphiccra, Serville, Ann. Sci. Nat., xxii, p. 271. 



Types, X. emargindta and trilincata, Serv, 

 These species belong to the family Gyrtacanthacridm, and 

 to the American subfamily Tropinotinm, and have nothing 

 to do with the types of Lamarck and Latreille. 



1839. Xiphoccra, Burmeister, Handb. Ent., ii, p. 612. 



Used by Burmeister in Serville's sense, for various 

 American species of the allied subfamily Tetrata^niinx. 

 The name cannot, however, be retained in the form 

 Xiphoccra, iov Xiphoccra was used by Macquart in 1834 

 for a genus of Diptera, and has also been used by later 

 Dipterists under the various forms of Xiphoccra, Xipho- 

 ccrus, Xi/phidicera, Xyphoccra, and Xyphoccrus. 



1876. Xiphoccra., Stal {ncc Burmeister), CEfv. Vet. Akad. 

 Forh., xxxiii (3), p. 37 (1876); Saussure, Spic. Ent., 

 ii, pp. 19, 27, 30, 35 (1887). 



The types given by Lamai'ck for Xiphiccra are G. galli- 

 naceus and scrrijjes, Fabr., for the latter of which Latreille 

 substitutes carinatus, L. The genus is distinguished by 

 its Truxaliform antennae, which at once throws out G. 

 gallinaccus, which is one of the Ma,stacid[e. Nor is the 

 character well marked in G. carinatus, of which G. sci^ripcs 

 is usually considered a synonym ; but it is pronounced in 

 G. cucullatus, Stoll, which is described by Serville under 

 the name of carinatus; and we are therefore justified in 

 regarding cucullatus as the insect which Lamarck and 

 Latreille regarded as G. scrripcs or carinatus, and there- 

 fore as the true type of the genus Xiphiccra. 



1831. Porthctis, Serville, Ann. Sci. Nat., xxii, p. 270. 



Type Acrydium dcntatum, De Geer ( = Gryllus carinattis, 

 Linn.). 



If we assume that Lamarck and Latreille had correctly 

 identified G. carinatus and G. scrripcs, Porthctis would 

 become a synonym of Xiphiccra, and a new name would 

 be required for G. eancscens and its allies ; but as the 

 identification is doubtful, both generic names may be 

 retained, at least provisionally.
