STEPS TOWARDS A REVISION OF CHAMBERS' INDEX, WITH 

 NOTES AND DESCRIPTIONS OF NEW SPECIES.

LITHOCOLLETIS, Z. 



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

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

 tions contained in three papers published in the Stettiner Bntomolo- 

 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 Kevision 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 LithocoUe- 

 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 argentifimbrlella, Clem. (1859). 



^fuscocostella, Chamb. (1875). 



2. Lithocolletis quercialbella, Fitcb, (1859). 



= Jongestriata, F. ^' B. (1873). 

 =^quercibella, Chamb. (1875). 



3. Lithocolletis subaureola, Frey, (1878).
