214 Mr. J. O. Westwood's Descriptions 



Evania Cubce, Guerin. Westw. Trans. Ent. Soc. vol. iii. p. 242. 



M. Guerin-Meneville (Iconogr. du Regne Animal, Texte, p. 

 405) states, that " on ne doit pas la distinguer de I'Evania l<zvi- 

 gata decrite par Olivier dans l'Encyclopedie Methodique." 



Evania Desjardinsii, Blanchard. Westw. Trans. Ent. Soc. 

 vol. iii. p. 242. 



According to M. Guerin-Meneville (Revue Zoologique, 1843, 

 p. 334), this supposed species is the male of Evania laevigata, the 

 Evania appendigaster of Blanchard being the female of the same 

 E. laevigata. 



Evania rufipes, Fabricius. Westw. Trans. Ent. Soc. vol. iii. 

 p. 245. 



The Evania thoracica, Blanchard, Hist. Nat. Ins. (ed. Dumesnil, 

 iv. p. 299), from Carolina, is stated by M. Guerin-Meneville 

 (Rev. Zool. 1843, p. 334) to be identical with this Fabrician spe- 

 cies, which is a native of South America; but by a note subse- 

 quently published by M. Guerin (Rev. Zool. 1844, p. 39) it ap- 

 pears that the two species are distinct, the thoracica of M. Blan- 

 chard being only two lines long, and not having the four fore-legs 

 red, as described by Fabricius. The description given by M. 

 Blanchard, '* toute la partie superieure du thorax est d'un rouge 

 de brique," also removes it from my Evania bicolor, Trans. Ent. 

 Soc. vol. iii. p. 246, which has the thorax entirely ferruginous. 

 It will, therefore, be necessary to reinstate M. Blanchard's species 

 under the name of 



Evania dorsalis, 

 « 



in order to avoid confusion with the two other species to which 

 the name of thoracica had been applied by Drs. Klug and Leach. 



Evania (Hyptid) Poeyi, Guerin-Meneville, in Rev. Zool. 1843, 



p. 335. 



This species is closely allied to E. petiolata, Fab., but is larger, 

 and the scutellum is not black. The fore wings have the cells 

 obliterated, those at the base of the wings being open and incom- 

 plete, whereas in E. minuta the latter are complete and closed. 

 The metasternum is not furcate. It is a native of Cuba, and 

 measures 9 millemetres in the expanse of its fore wings.
