AMERICAN WORKERS IN HEMIPTERA, 
There was issued during March an informal pamphlet entitled “List of 
_ American Workers in Hemiptera; their Projects and Bibliographies. 1, Heteroptera." 
‘The object of the pamplet was an attempt to summarize the present status of 
_ work upon Heteroptera in the United States, which includes name and address of 
4 workers, their position or institution affiliated with, character of work, prob- 
_ dems engaged in or expecting to undertake, and bibliography. Data blanks were 
sent to all persons known to be especially interested in Heteroptera, but it is 
only natural that all workers or students could not be reached. However, besides 
_ the purely economic workers, 26 men returned the blanks filled in and hence are 


_ listed in the pamphlet. A second such pamphlet dealing with Homoptera 
_ is in course of preparation, Any one desiring a copy of either should re- 
quest same by writing to the compiler, Mr. Edmund H. Gibson. [Division of In- 
sects, U. 8S. Nat. Mus.]
