ART. V.-INDEX TO THE DESCRIBED TINEINA OF THE UNITED 

 STATES AND CANADA. 



By Y. T. Chambers. 



Having, in the last ten years, described a large number of new species 

 of the Tinema, with notes on many other species previously known in 

 various scientific periodicals, and the notes and descriptions referred to 

 being, therefore, scattered through various volumes, I have been urged 

 by other entomologists to catalogue the species. Many other species 

 had been previously described by other authors, whose publications 

 were equally scattered and inaccessible with my own, so that, for my 

 own convenience in the study of the group, I had prepared an index for 

 ready reference to the species, and that index needed but little alteration 

 to make it complete, so far as I am acquainted with the species. 



Convinced that a catalogue of my own species only would be of but 

 little service to students, while the writings of others were so inacces- 

 sible, and, indeed, unknown to many American entomologists, it has 

 seemed to me that a publication of this index would answer the pur- 

 pose better than a mere catalogue of the species. I therefore offer it in 

 the hope that it may prove as useful to brother entomologists as it has 

 been to me. 



It is only an index of the species as American species. Many of our 

 species are identical with those of Europe, and I have not attempted to 

 abstract the entomological literature of Europe as to these species. 



As to the European literature of the subject (American Tineina), I have 

 not attempted to bring it down to a later period than the latter part of 

 the year 1875. For, having been absent in Colorado during the greater 

 part of the time, it was impossible to keep au courant with it ; and if 

 any European publications have been made since that time they are 

 unknown to me. A letter from a gentleman in Europe, received by me 

 in 1875, informed me that Professor Frey was then engaged upon a 

 work on American Tineina^ but if it has been published I have not 

 learned the fact. So far as American publications are concerned, the 

 index is brought down to November, 1877, with references, also, to vol- 

 ume 10 of the Canadian Entomologist (1878), which will contain notes 

 already prepared upon some species. There are also references to spe- 

 cies described upon previous pages of this volume. These references are 

 simply to the volume, not to the page. 



V Professors Zeller and Frey have described many of our species in 

 various European publications. Usually (always'?), however, these pa-
