8 BULLETIN 112, UNITED STATES NATIONAL MUSEUM. 



The above list refers only to the early collectors who have fur- 

 nished type specimens to the collection. To the many later private 

 collectors who have wisely and generously contributed material to 

 the United States National Museum I hope to give individual credit 

 in another publication. 



There are a few new species on the point of publication which 

 may possibly be delayed until after the issue of this bulletin. I have 

 (bought best to include their names, with references to the proposed 

 vehicle of publication, to which the reader may hereafter add the 

 page references when available.
