408 Miscellaneous. 



Walker described his geuus Dwa in the twelfth volume of his 

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

 two species, I). stiinnlans,=Plusiodonfa Thonup, Guen., and I), con- 

 dMcens, = P. chalqttoldcs. Gutn. On the following page he described 

 another new genus, Gadera, with two species, G. incitfins and 

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

 G. ripellcns was Uraziliau. As a matter of fact both are natives of 

 Jamaica. 



Xow as P. cuitipresA-ipidpis, from the United States, is the type of 

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

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

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

 Bpecies of Guenee's genus Phiaiodonta fall into Deva, AValker ; 

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

 subsequently, fall into Pohjchrysia, Hiibner. 



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

 Deva belongs to the Calpidfe) ; it differs from typical Plnsia in its 

 enonnously 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, subaiigulatL-d. 



The genus Pohjchrijsia will include P. spItii'Uda, = Deva sphndida, 

 from Japan ; P. c-aureuiii, = Plusia c-aurcum, from Europe ; P. mi- 

 k.(dina,=: Plnsia mikadina, from Japan ; P. purpurvfera,=: Devu 

 purpmriijera, from the United States; P. moneta, = Plus{a rno)icfa, 

 from Europe ; and P. pall iyera,= Deva pallifjera, from the United 

 States. 



Of the above species P. c-aureum and P. mikadina 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 scries 

 will ])rove this to be an insufficient distinguishing character. 



Dr. vo)i Lendenfeld on the Central C'avitif in Euplecteila. 

 By E. A. MiNcniN. 



In the last number of this Journal (April 1^92. p. 337) Dr. von 

 Lendenfeld calls me to task for having, as he says, attributed 

 to him the statement ( which he well terms " preposterous ") that 

 the central cavity of En/'hctclla aqieryillum is a pseudoscular tube 

 forming pait of the inhalant system. He adds that he never 

 doubted the exhalant nature of the central cavity in Enphctella and 

 that he fails to see how any one can gather from his statements 

 such a meaning as I impute to them. 



No one would gather from reading Dr. von Lendenfeld's note 

 that everything T inferred as to his opinions was supix)rted by full 

 quotations from his writings, and 1 will therefore content myself 

 by merely amplifying what I have ah'eady written.
