7()8 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxv. 



From Miss Mary Murtfeldt, the Nestor among students in this 

 group in America, I have received not only material but also much 

 interesting information, which no one else could have supplied, par- 

 ticularl}^ concerning some of Chambers' species. 



To Prof. C. H. Fernald and to Dr. William G. Dietz I am under 

 obligation for allowing me to study their collections in their homes, 

 also for various suggestions and for specimens. 



Professor Fernald's collection included that of Miss Murtfeldt, with 

 her types and man}^ of the types of Chambers and of Lord Walsing- 

 ham. Of especial value were those specimens furnished with Lord 

 Walsinghanrs blue labels, which were passed upon by him in 1882.^ A 

 notebook in Lord Walsingham's handwriting, with notes and deter- 

 minations, corresponding to the numbers on these blue labels, was 

 loaned me by Professor Fernald, thus enabling me also to verify iden- 

 tifications of man\^ specimens in the Museum of Comparative Zoology, 

 Cambridge, Massachusetts, especially those which formerly belonged 

 to the Peabody Academy of Science, in Salem, Massachusetts. 



Dr. Dietz \s collection contained his types and several specimens 

 named by Lord Walsingham. 



The collection in the museum in Caml)ridge contains nearly all of 

 Zeller's types and a great many of Chamliers', besides the specimens 

 named ])v Lord Walsingham. This collection proved the richest of 

 any in authentic specimens, and although careful discrimination was 

 necessary among Chambers' types, many species were identified here 

 which would otherwise have remained unknown to me. I am indebted 

 to Mr. Sanmel Henshaw for nuich courtesy and information given me 

 during my stay in Cambridge, as well as for sending me many speci- 

 mens needed for reexamination after my return to Washington. 



The collection of the Philadelphia Academy of Natural Sciences has 

 unfortunately but a few of Clemens' types left. There are, however, 

 some types and specimens named by Lord Walsingham. To the cura- 

 tor, Dr. H. Skinner, I owe thanks for giving me every facility for 

 examining the collection and manuscripts. 



The Belanger collection, formerly in the Laval University, Quebec, 

 containing Cham})ers' types of Canadian Tineina, was obtained by the 

 writer through the courtesy of the present curator, Rev. Dr. C. E. 

 Dionne. and is now in the U. S. National Museum. 



What little was left of the late Mr. William Saunders' colli'ction 

 of Tineina, consisting of fraguK^nts of some of Chambers' types, was 

 secured, together with some new Canadian material for the U. S. 

 National Museum, through the kind agency of Dr. J. Fletcher, Ottawa, 

 Canada. 



From Mr. William D. Kearfott I received for study a well-pre- 



Trans. Am. Ent. Soc, Phila., X, 165-204.
