Notes on the North American LEPIDOPTERA 

 in the British Museum and described by Mr. Francis Walker. 



BY AIT,. R. QUOTE AND COLEMAN T. U0ISI.NSON-. 



We have recently enjoyed the opportunity of examining the North 

 American Moths contained in the British iMuseum Collection and 

 which have been described by Mr. Francis AValker in the " Lists of 

 the Lepidopterous Insects " published by that Institution. Bringing 

 with us material for comparison, and aided by the kind attentions of 

 Dr. Gray, Messrs. Walker. Waterhouse and Butler, we have been 

 able to identify many of the species described by Mr. Walker which 

 were previously unknown to American Entomologists except by name 

 and tlicir notoriously insufficient limitation in the work above alluded to. 



It is perhaps unnecessary to do more than to refer here to the very 

 general condemnation with which scientists have received the ex- 

 tended works of Mr. Walker on the Insects contained in the British 

 Museum (kdlections.* It will be simply sufficient to state that the 

 opinion has been expressed that these works should be ignored, and that 

 the law of priority should be suspended in its 0|5eration with regard to 

 these Publications of our Author. It is, however, perhaps, useless to 

 discuss the propriety of a course which it is not likely could be unani- 

 mously and strictly adhered to. Since many of Mr. Walker's des- 

 criptions are recognisable and the types are contained in a Public
