the Genus 'I'um.'U rii;i, fF/'/-. 177 



regarded liis species as sexually (liin()i"i)liic, and pointed out 

 the difl'erciices between the c? '"-'''^ ^''^ ? ; especially tlic 

 greater extent of the grey colouring in the (^ , which in the 

 ? was cut off hy tlie white costal area above the dorsal 

 patch. I have both these from Jimiaica, with both sexes of 

 each, and they are distinct species. Tlie less clouded form, 

 of which Zeller had only the ? , is not the same as the 9 

 desciihed by Walker, and seems unirormly smaller and paler 

 than the other ; but there is one |)oint which now enables 

 me to identify without douljt Zeller^s r? aduslella — he 

 specially mentions " Fiihler beim ^ mit auffalleud verlaug- 

 erten .... Wurzelgliedc." This applies to the darker form 

 only, precisely as seen by Zeller, and is most remarkable. 

 Walker's two ? ? are undoubtedly this species, oF which I 

 have now a J with the long basal joint, but his ^ differs in 

 the short basal joint of the auteuuifi as well as in the details 

 of the markings. 



There are at least three other species, differing very slightly, 

 from Cuba, Jamaica, and Domingo. Zeller's Portorico 

 females may probably come to be identified with one of these 

 and jiossibly with the genus Euurne, ]Mschl. + Saalm. 



1 send these notes at once, since 1 iiave no leisure at present 

 to study in further detail the interesting papers on Miero- 

 lepidoptera lately published and kindly sent by Mr. Busck. 

 No one can more highly appreciate the excellent work he is 

 doing ; but it seems a pity that facilities are not afforded to 

 authors of seientilic i)apers pui)lishcd by the American 

 Government for correcting proofs. Had the proofs passed 

 through the author's hands, such errors as "Zellar^^ for 

 "Zeiler," "Flori\i" for " Horte ," '' nievosella" for '' nivo- 

 sella," " Hyponementidai '^ for " Hyponomeutidaj,'^ &c , &e., 

 would certainly have been avoided : all these and " Ypono- 

 meutidte," to wdiich / am said to have referred Tamurrha, 

 are ou p. 729. 



If I were wrong in placing the genus Tamarrha in the 

 Hyponomeuiidoe, additional uiaieiial obliges me to take 

 exception also to associating it with the Qilco[)horidifi. Does 

 Mr. Busck know the African genus Gyinnugrammasiwd olh.ev% 

 with veins 7+8 of the fore wings sialked^ or Trichosiibas, 

 Zeller, ( = § Penthetria, li. Edw.) ? and would these affect his 

 opinion as to the extent of the llyponomeutidse ? I would 

 now rather incline to placing Tamarrha with the Azinidae, 

 founded on an Asiatic genus and characterized by the con- 

 tinuation of the discoidal vein direct to vein 8. 



1 cannot conclude without drawing attention to a quotatiou 

 ou p. 733, where the author cites Dr. Dietz's reference to
