STEPS TOWARDS A REVISION OF CHAMBERS' INDEX, WITH 

 NOTES AND DESCRIPTIONS OF NEW SPECIES. 



By Lord Walsingham. 



[Continued from p. 326 of vol. 11,] 



LITHOCOLLETIS, Z. 



1 have lately had the advantage of purchasing the types of North 

 American Tineidce which were used by Professor Frey for the descrip- 

 tions contained in three papers published in the JStettiner Entomolo- 

 gische Zeitung. They confirm with very few exceptions the conclu- 

 sions arrived at trom independent evidence as to the synonymy of the 

 numerous species lately noticed in "' Steps towards a Revision of Cham- 

 bers' Index." In one or two instances it is necessary to make slight 

 corrections and as these should not be delayed I submit herewith a 

 revised list of the recognized American species of the genus Lithocolle- 

 tis in what appears to be their natural sequence according to their re- 

 lationship with the European species as arranged in Staudinger and 

 Wocke's Catalogue. 



This list embodies the following corrections : 



1. Lithocolletis argentifimbriella, Clem. (1859). 



=fuscocostella, Chamb. (1875). 



2. Lithocolletis quercialbella, Fitch, (1859). 



= longestriata, F. 4- B. (1873). 

 = (juerci1)ella, Chamb. (1875). 



3. Lithocolletis subaureola, Frey, (1878).
