354 ENTOMOLOGICAL NEWS. [February, 



record such notes and data as may seem of interest to hymenop- 

 terists. 



Mr. Fox, in his monograph, indicates twenty species of 

 Crabro as occurring within the Hmits of this State. The fol- 

 lowing list includes twentj^-eight species, the additional number 

 being due to the extension of the range of six species to this 

 region, and two species are described as new. 



In their flower-visiting habits the members of the, genus 

 Crabro seem to have a preference for the blossoms of the 

 Umbelliferae. Most of the specimens recorded from Olympia 

 were taken upon the flowers of an umbelliferous plant growing 

 in an open meadow along the Deschutes River. At Seattle a 

 number of specimens were taken during the Summer upon the 

 flowers of cultivated parsnips, and in the Fall upon those of 

 Cariun gairdneri and Aiigelica gcmijicxa. A few specimens 

 occurred at plants of other families, such as Anaphalis mar- 

 garitacea, Achillea millefolhun, etc. A series taken at Corval- 

 lis, Oregon, were, with few exceptions, found upon the flowers 

 of Heracleum lanatiim. 



The localities mentioned in the following notes are all within 

 the Puget Sound basin, except Pasco, Wawawai, Almota and 

 the Blue Mountains, which are in Eastern Washington. Hence 

 the former are in the Transition zone, while the latter are in the 

 Upper Austral zone, as indicated by Dr. Merriam in his paper 

 on the faunal areas of the .United States. 



In the preparation of this paper the writer wishes to ac- 

 knowledge the assi.stance of Mr. Fox in determining some of 

 the more difficult species.
