H. C. FALL 293 



for which I am indebted to the unfailing courtesy of Dr. Howard 

 and Messrs. Schwarz and Barber; that of the American Entomo- 

 logical Society of Philadelphia, including the Horn Collection, 

 through the kindness of Dr. Skinner; and also that of the Snow 

 Collection in the University of Kansas. From private collec- 

 tions I have received substantial aid — in most cases their 

 entire material — from Messrs. Leng and Beyer of New York, 

 Mr. Schaeffer of Brooklyn, INIessrs. Liebeck and the Wenzels 

 of Philadelphia, Professor Wickham of Iowa City, ]\Ir. Warren 

 Knaus of McPherson, Kansas, Mr. Chas. Dury of Cincinnati, 

 Mr. C. A. Frost of South Framingham, Mass., Mr. Loding 

 of Mobile, Mr. A. B. Wolcott of Chicago, Dr. Blaisdell and 

 Dr. Van Dyke of San Francisco, and Dr. Fenyes of Pasadena, 

 Cal. I have also gone over carefully the collection of the 

 late Frederick Blanchard of Tyngsboro, ^Nlass.; have several 

 times — thanks to IMr. Henshaw's courtesy — examined the Le- 

 Conte types at Cambridge, Mass., and am indel^ted to Mr. 

 Bowditch not only for the privilege of studying many of the 

 tjpes of his lately described species, but also for the opportunity 

 of taking a look at a number of the Suffrian types sent to him by 

 Dr. Taschenberg of Halle. Since then I have myself received 

 from Dr. Taschenberg, through the kind offices of Dr. Walther 

 Horn of Berlin, several Suffrian types, which have enabled me 

 to fix the identity of a number of species not hitherto known or 

 properly interpreted by American students. Quite recently, in 

 response to a request to the British Museum, kindly seconded by 

 Mr. Champion, Mr. C. J. Gahan has sent me for study represen- 

 tatives of about a dozen Mexican species, including several of 

 Jaeoby's and a number of Suft'rian's as determined by Jacoby. 

 The consideration so kindly^ shown by ]\Ir. Gahan and the ^lu- 

 soum authorities is especially appreciated, coming as it does at a 

 time when the working force of the Museum is much reduced, and 

 the hazards of transportation considerably enhanced by the 

 existing European war. Finally I am under especial obligation 

 to Mr. Schwarz of the National [Museum and my neighbor. Dr. 

 Fenyes, for bibliographical notes or the loan of some of the older 

 papers not in my own librarj-.
