SPIDERS OF THE FAMILY ATTIDAE FROM AMES 233 



undertaken in Iowa, it is the first that has b^en published. In 

 1896 Banks described a new Drassid, which had been collected 

 at Ames by Professor C. P. Gillette. A number of years previous 

 Professor Gillette collected eig'hty species at Ames which were 

 i'lentiried ly Banks in 1891. A number of these were Attidae and 

 have been included in this article. On account of tlie peculiar 

 haliits of the Attida? they are, in comparison with other families, 

 poorly represented in collections. 



The most important contributions to our knowledge of North 

 American species of Attidae are those of Hentz; of Gep'rge W. 

 and Elizabeth G. Peekhani; and of J. H. Emerton. The papers 

 of llentz were published originally in the Journal of the Boston 

 Society of Natural History, from 1842 to 1845. Those of the 

 Peckhams were published in the Transactions of the Wisconsin 

 Academy of Sciences. Arts, and Letters, 1883 to 1889, and later, 

 in 1901, a ''Revision of the Attidae of North America," w-as 

 published in the Transactions of the Wisconsin Academy. 

 Emertoii's works, which dealt entirely with ihe New England 

 Attidae, were published in the Transactions of the Connecticut 

 Academy of Arts and Sciences 1888 to 1892. 



The works of Baron Walkenauer, 1837 to 1847, and that part 

 of Die Araehniden, l)y C. Koch published in 1846. contain de-^ 

 sci'ii)tiotis of many American Attidse, but owing to the vague- 

 ness of the descriptions comparatively few have l>een identified 

 vith certainty, Baron Walkenauer described sixty-four species, 

 but upon comparing them with nearly all (,2 Hentz 's species 

 and with many others from difi^erent sources, the Peckhams were 

 able to identify only four.
