150 ENTOMOLOGICAL SOCIETY 



County, Colorado. In 1881 Rev. O. P. Cambridge 1 described 

 three species from Newfoundland, and in 1885 Mr. F. W. 

 Cragin 2 published a list of ten Spiders from Kansas. 



These are all the local lists of Spiders published heretofore 

 in this country. 



Washington, the seat of many scientific institutions, . can 

 also boast of quite a number of professional entomologists, 

 and adding to them the little flock of amateur naturalists, 

 who find pleasure and recreation in the study of entomology 

 outside of their daily occupations, this city can be proud of its 

 number of representatives of this branch of natural science ; 

 but I must state here that the amateur naturalists are greater 

 enthusiasts, more diligent workers, possess larger collections, 

 and have in general done more to explore the territory of the 

 District in regard to its entomological fauna than their profes 

 sional brethren. 



All of our entomologists seem to prefer certain old localities 

 for collecting, where they are sure to be rewarded for their 

 labors, instead of hunting for new fields. Our oldest ento 

 mologist in the District, who accumulated during the thirty- 

 five years of his residence here one of the finest collections of 

 Coleoptera, has always visited his few old hunting places over 

 again, and can hardly be induced to try a new locality. The 

 consequence is that the territory of the District of Columbia is 

 by no means fully explored, and to speak of a list of Spiders 

 from here means only a list of a part of this territory. 



For over ten years I have been the sole collector of Arach- 

 nida in the District of Columbia, and I must confess that I 

 have followed the example of my entomological colleagues and 

 visited generally the same localities, viz., Soldiers' Home, the 

 Virginia border of the Potomac and the Rock Creek valley, 

 with a few excursions to Bladensburg, the lower Potomac, and 

 Great Falls and Cabin John's Bridge.
