Revision of the Nomenclature of the Brachyum. 165 



Xanthias for Xanthodes * Dana, May, 1852. (Xanthodes Guenee, 

 Spec. Gen. d. Lep., V.T, 209, Jan., 1852, Lepidoptera. Noticed in 

 Bibliographic de la France, Jan. 10, 1852.) 



The following published names should be substituted for pre 

 occupied names : 



Palicus^ Philippi, 1838, for Cymopolia Roux, 1828. (Cymopolia 

 Lamouroux, Hist. Pol. Coral. Flex., 292, 1816.) 



Podohuenia Cano, 1889, for Ixion Paulson, 1875. (Ixion Reitter, 

 Verh. Ver. Briinn, XT, 44, 1872, Coleoptera, ^de Zool. Rec., 1873.) 



Dilocardnus Milne-Edwards, 1853, for Orthostoma Randall, 1839, 

 type 0. dentata Randall, 1839 = Dilocardnus multidentatus von 

 Martens, 1869. ( Orthostoma Ehrenberg, Symbolse Physicse, Anim. 

 Evert., Decas Prima, 1831, Verrnes.) 



Kaempferia suggested but not adopted by Miers, 1886, for Ma- 

 crocheira de Haan, 1839, ' preoccupied.' (Macrochira Meigen, 111. 

 Mag., 1803, Diptera. Macrocheirus Schonherr, Gen. et Spec. Cur- 

 cul., 1838, Coleoptera, concerning which he says ' Macrocheira 

 Nov. Gen. et Spec. Dom. de Haan in Litteris.') 



The following may be used for names preoccupied though 

 with different gender terminations : 



Rhodia Bell, 1835, for Herbstia Milne Edwards, 1834. (Herb- 

 stium Leach in Desmarest, Diet. Sci. Nat., XXVIII, 301, 1823, 

 Macrura.) 



Grapsillus MacLeay, 1838, for Trapezia Latreille, 1825. (Trape 

 zium Humphrey, Mus. Calonnianum, 1797, Mollusca.) 



Hypopeltarium $ Miers, 1886, for Peltarion Hombron and 

 Jacquinot, 1852? (Peltarium G. Fischer de Waldheim, Bull. 

 Soc. Imp. Nat. Moscou, XVII, part 1, 106, 1844, Coleoptera.) 



Eurypanopeus A. Milne Edwards, 1880, for Panopeus Milne 

 Edwards, 1834. (Fanopea Menard, Ann. Mus., IX, 135, 1807, 



*Ortmann, Zool. Jahrb., Syst., VII, Heft 3, 443, 1893, unites Xanthodes 

 with Xantho. 



f Since the publication of my 'Synopsis of the American Species of 

 Palicus Philippi (= Cymopolia Roux),' pp. 93 to 9$ of these Proceedings, 

 Professor Jeffrey Bell and Dr. Hilgendorf have kindly sent me copies of 

 the original description of Palicus. Though brief, it agrees with Cymo 

 polia. Dr. Philippi was doubtless soon convinced of the identity of his 

 genus with the earlier one, as the complete description and figure which 

 he promised to publish in Wiegmann's Archiv never appeared. 



J Hypopeltarium was substituted by Miers, 1883, for Peltarion (name 

 preoccupied) and has been in use ever since. 



\ Admitting that Eurytium Stimpson, 1859, is a distinct genus.
