I.—The Sphegoidea of Nebraska 
BY HARRY SCOTT SMITH 
_ The following paper is the result of a study pursued by the 
_ writer at odd intervals during the past two years, and is based 
_ on the material contained in the collection of the University of 
_ Nebraska. Although the list is a fairly large one for a single 
state, nothing like systematic collecting has been done on the 
group, and it is expected that a great many additional species will 
be found in the near future. The only portion of the state that 
has been at all closely collected is Sioux county, where, during 
the past ten years, several zoological expeditions in charge of 
Professor Lawrence Bruner have been sent. This region is fast 
- becoming famous from the standpoint of the zoologist as well 
as the paleontologist, and from this locality many interesting 
records are obtained. Of the 200 species treated in this paper, 
- 118 have been taken in Sioux county, and 60 of these have not 
_ been taken elsewhere within the state. With a single exception 
these trips were. made during the month of August, so that in 
all likelihood, if the region were worked at some other time of 
the year, many other species would found. In order to avoid 
_repetition in the following pages it may be stated here that Indian 
creek, Jim creek, Monroe canyon, Warbonnet canyon, Agate, and 
_ Glen are found in the above mentioned county.
