A PRELIMINARY LIST OF THE PROCTOTRYPOID 



HYMENOPTERA OF WASHINGTON, WITH 



DESCRIPTIONS OF NEW SPECIES.* 



By Charges T. Brues. 



On account of its large extent and varied life conditions, the 

 State of Washington supports an unusually interesting fauna. So 

 far it has received but scant attention from entomologists in com- 

 parison to that which has been bestowed upon most other parts 

 of the United States, and it offers an almost virgin field for the 

 student of many groups of insects. During a part of the past 

 summer I had the good fortune to enjoy the hospitality of the 

 Puget Sound Marine Station, located among the islands of Puget 

 Sound in the extreme northwestern part of the state. While there 

 I had the opportunity, through the kindness of my friend, 

 Professor A. L. Melander, to examine a collection of parasitic 

 Hymenoptera, obtained principally in the country surrounding the 

 site of the laboratory and on the slope of a nearby mountain about 

 2,500 feet in height. 



I have worked over only the material representing the super- 

 family Proctotrypoidea, and although it contains but a small num- 

 ber of species from a very restricted region, it nevertheless more 

 than trebles the number of recorded forms of this group known 

 from the state. I have therefore included for mere convenience 

 such other records as I have been able to gather from published 

 and other sources relating to Washington. 



The Proctotrypoidea will undoubtedly be found to be well 

 represented in the state when carefully collected, especially in the 

 Humid Transition Area, where the present material was obtained. 

 One genus, Proctotrypcs. seems indeed to reach its highest devel- 

 opment there, to judge from the extensive series of species which 

 are contained in the collection.
