extended, or were preserved with a due regard for the safety of their 

 palpi and antennae, so necessary for the correct determination of many 

 genera and species. Secondly, having in many cases only one or two 

 examples of each species, and these subject to the not insignificant risks 

 of another journey between America and England, I have been most 

 unwilling to denude wings for the purpose of examining their neuration. 

 And. thirdly, the immense number of nearly allied species described by 

 Mr. Chambers of which he has given us no figures, and of which I have 

 not seen the types, have rendered it impossible, especially in such genera 

 as Gelechia and B/ast'obasi*, satisfactorily to determine many of the 

 numerous species contained in the collections submitted to me. In such 

 I have advisable merely to indicate the genera in my 



and- not to attempt to offer, in this paper, the 

 arks which in soin< have occurred to me upon their probable 



nomenclature and synonymy. 



After returning my cordial thanks to the owners of the different 

 collections which have been placed at my disposal, I must acknowledge 

 the ureat assistance derived from Mr, Chambers's " Index to the described 

 Tineina of the United States and Canada," published in 1878, in the 

 ' 'in of the United States Geological and Geographical Survey,' 

 vol. iv, which has greatly facilitated reference to numerous scattered 

 papers in the 'Canadian Entomologist.' the 'Cincinnati Quarterly Journal 

 of Science,' the ' Journal of the Cincinnati Society of Natural History,' 

 and other periodical publications, and which is referred to hereafter in 

 this paper, for the sake of brevity, as the " Index," as well as from 

 Mr. Stainton's valuable republication of Dr. Clemens's papers on " Tineina 

 of North America," hereinafter referred to under that name, which has 

 been rendered doubly serviceable to me from my having first studied 

 it at Philadelphia in 1872, and made notes upon Dr. Clemens's typical 

 specimens which were then before me. Good colored drawings of all 

 the species in the various collections, except such as are represented in 

 my own cabinet, have been made for me by Mr. Edwin Wilson ; and 

 I hope, in course of time, that these may he rendered available to the 

 public either by publication in Mr. C. 0. Waterhouse's most useful 

 1 Aid to the Identification of Insects,' of which the first volume has 

 just appeared, or in some other entomological journal. The numbers 

 which precede the names of the various species mentioned in this 

 paper correspond to those used in my catalogue of the specimens 

 now returned to Prof. Fernald, and are attached on blue labels to 

 the specimens themselves.
