408 Miscellaneous. 



Walker described his genus Deva in the twelfth volume of his 

 4 Catalogue of Lepidoptera Heterocera,' p. 962, and included in it 

 two species, D. stimulans,=Plusiodonta Thomcr, Guen., and D. con- 

 ducens,B=P.chalcytoide8,G[\ien. On the following page he described 

 another new genus, Gadera, with two species, O. incitans and 

 G. repellens, both without localities, though ho concluded that 

 G. repellens was Brazilian. As a matter of fact both are natives of 

 Jamaica. 



Now as P. compressipalpis, from the United States, is the type of 

 Plusiodonta, and differs from all the other species associated with it 

 in its pectinated antenna3, and as the species of Deva and Gadera 

 differ from one another in no character whatever, the bulk of the 

 species of GueneVs genus Plusiodonta fall into Deva, Walker ; 

 whilst the species referred to Deva by Walker, Grote, and myself 

 subsequently, fall into Polyclirysia, Hiibner. 



The genus Polyclirysia, in my opinion, is a true Plusiid (whereas 

 Deva belongs to the Calpidas) ; it differs from typical Plusia in its 

 enormously developed Deltoid palpi, the terminal article of which is 

 curved, compressed, and tapering, the fringe of scales being elon- 

 gated below the article ; the outer margin of the primaries is 

 usually, but not invariably, subangulated. 



The genus Polyclirysia will include P. splendida, Deva splendida, 

 from Japan; P. c- a ureum, = Plusia c-aureum, from Europe; P. mi- 

 Icjdina, Plusia mikadina, from Japan; P. purpuriyera, = Deva 

 purpuriyera, from the United States; P. moneta, = Plusia mcmeta, 

 from Europe ; and P. palligera,=Deva palliyera, from the United 

 States. 



Of the above species P. c-aureum and P. milcadina are nearly 

 allied, but the former has the golden marking on the centre of the 

 primaries of a O-shape, whereas that on P. mikadina is comma- 

 shaped, > ; at the same time it is quite possible that a large series 

 will prove this to be an insufficient distinguishing character.
