species that might have been swept from the tall grass and low 

 bushes of the neighboring fields at any time during the sum- 

 mer. The only adults were six species of Attidae, but one of 

 them, Zygoballus terrestris, a regular autumn flyer. The small 

 Linyphiadae, which are so characteristic of the late autumn 

 flights, were entirely absent. The flying went on several days 

 of the following week, and on October 17 twenty-six species 

 were taken, three of them adult Attidae, and eight adult small 

 Linyphiadae that live in the summer near the ground, among 

 grasses and other low plants. As the season went on the 

 number of Linyphiadae increased and that of the Attidae and 

 Thomisidae diminished, only Xysticus quadrilincatus continu- 

 ing through the season, with Misumena asperata abundant the 

 first two weeks. Tmeticus bostoniensis and Diplostyla albo- 

 ventris came in on October 17 and, opposite certain fields, con- 

 tinued abundant through the season. 



Of the regular fliers the young of all the species of Pirata 

 and Pardosa increased in numbers until the very last of the 

 season, and at all times there were some individuals of Epeira 

 prompta, Epeira displicata, Shiga variabilis, Anyphoena rubra 

 and Dolomedes sexpunctatus. The largest number of species 

 and of individuals was taken on November 8, when there were 

 adults of twelve species of Linyphiadae and young of two 

 others, with great numbers of young Lycosidae of all kinds. 



The best flying weather of the season occurred November 

 16 between 9.30 and 10.30 A. M., when a hundred spiders oi 

 the species listed under that date 'were taken. At that time 

 there was no wind that could be felt, and several half-grown 

 Pardosa were seen to rise vertically from fence posts until out 

 of sight. At 10.30 the wind rose slightly and changed to the 

 east, and the flying stopped. Nothing new in regard to the 

 method of flight was observed this season. Several spiders, 

 while ascending, were seen to draw out a thread attached to 

 the starting point. Several species were seen to drop and hang 

 swinging by a thread, two or three inches long, and in this posi- 

 tion to let out flying threads and drift away in the air. 



Sixty-nine species in all were observed. Very young Epeira 

 insularis and trifolixim show that these species sometimes de-
