onyms. The exact relationship of the genera Tinayina Zeller, 

 Donylasia Stainton, Coclopocta Walsingham, and their allies is 

 not apparent at present, but I expect they will eventually be 

 proven to belong to the CYCNODIOIDKA. 



I am under much obligation to Lord Walsingham and Mr. 

 Durrant for type material of their genera in this group and to 

 Abbe J. de Joannis, who has liberally sent me type material of 

 his genus Mcndcsia. 



The genus Mouipha Hiibner (Meyrick) (Lavcrna Curtis) 

 forms the basis of another natural family, which according to 

 Durrant" should be called Lavernid;e. 



This comprises the bulk of the genera hitherto placed in 

 the Elachistidse, such as Cosmopteryx Hiibner, Statlunopoda 

 Stainton, Anybia Stainton, Pancalia Curtis, Chrysoclista 

 Stainton, Pcrimcdc Chambers, ItJwinc Chambers, Walishia 

 Clemens, Stilbosis Clemens, Cyphopora Herrich-Schaeffer, 

 Stagmotophora Herrich-Schaeffer, Blastodacna Wocke (=Lcn- 

 cophrync Chambers), Theisoa Chambers, Synalagma Busck, 

 Erineda Busck, and several others. 



This family, which is related to the Gelechiidae, Oeco- 

 phoridse, and Blastobasidae and which is rather higher in the 

 sequence than any of them, nearest to Gelechiidas, is restricted 

 to genera with long recurved, pointed palpi, with veins 7 and 8 

 in the fore wings stalked (or coincident) and with vein 7 to 

 costa. A revision of the North American moths of this family 

 is now under way. 



A third group is formed by the genera Scythris Hiibner 

 (=Arotrura Walsingham=Co//';n7a Busck), Bryophaga Rag- 

 onot, and Apostibcs Walsingham. This group I include tempor- 

 arily in the Plutellida?, though it may eventually be recognized 

 as a separate definable family ; I do this with much hesitation, 

 because my learned friend Mr. Edward Meyrick, in a recent 

 letter, has expressed it as his opinion that the group is allied 

 to and derived from the Oecophoridae ; but though the posterior 

 tibiae strongly suggest this family, I am unable to see how the 

 pterogostic characters could have been derived from cecophorid 

 stock. The real point of difference is probably our different 

 interpretation of the veins in the fore wing; Mr. Meyrick 

 regards vein 8 absent and vein 7 to costa, while the writer 

 believes it one of the dorsal veins which is absent and conse- 

 quently vein 7 to termen. 



The genus Coleophora and its few true allies form a fourth 

 group, which I believe we all agree is closely allied to and
