ISELY: EUMENID^ OF KANSAS. 255 



Williams was the head of the expedition. The party consisted 

 of four men, besides the chief, all graduate students in the de- 

 partment of entomology. 



The purpose of the survey was to study Insect distribution 

 in the territory covered and to add to the Snow entomological 

 collections in the Museum of Natural History at the University 

 of Kansas. This plan necessitated that the major portion of 

 the time should be spent in general collection. However, when- 

 ever a eumenid colony or a single nest was located, I was given 

 all the time necessary to devote to the study of the wasp's ac- 

 tivities. Many nests, which I would not have otherwise had op- 

 portunity to observe, were first located by Mr. Williams, who 

 directed me to them. He also made many helpful suggestions 

 regarding my observations and the method of conducting them. 

 All the eumenids collected on the trip were placed in my charge, 

 in order that I might have suflicient material for a systematic 

 study of the group. 



The counties covered by the survey are included by an al- 

 most square area, occupying the eastern half of the northwest- 

 ern quarter of the state. About one week was spent in each 

 county. Camp was pitched, generally in some central point 

 near a stream, and from this center radiated the daily collect- 

 ing trips. Eumenidse was collected in every county but one — 

 Barton.
