Aug. 17 (No. 82), and two males were found in the same forest 

 Aug. 22 (No. 123). 



Weed ('89, p. 87) states that this species is very abundant on 

 rocky ledges in parts of southern Illinois. He is of the opinion that 

 the winter is passed in the egg stage, and maturity is reached in 

 July. The young prefer grass, low vegetation, and piles of rubbish, 

 but when mature are found in a "great variety of situations," as in 

 the corn fields of the prairie parts of Illinois, in grasslands, among 

 brush, and in the forest ('92c, p. 1006). 



Liobunum ventrico sum Wood. (PI. LI, fig. 1.) 



Three specimens of this "daddy-long-legs" were taken in the up- 

 land Bates forest (Sta. IV, a) Aug. 22 (No. 123b) 



The young of this species hibernate, and maturity is reached 

 early in June (Weed, '92b, p. 264). This is exceptional, as most 

 species of this group pass the winter in the egg stage. The food of 

 daddy-long-legs consists mainly of dead insects (Weed, '89, p. 80). 



Liobunum grande Say. Stout Harvest-spider. 



This stout-bodied and short-legged species was found running 

 about on dry leaves in the upland forest (Sta. IV, a) Aug. 17 (No. 

 82) ; and in a damp ravine (Sta. IV, b) Aug. 20 (No. in). 



Consult Weed ('92b and '93 )for descriptions and figures of this 

 species. Very little appears to be recorded about it. 



Araneida 

 Epeirid;e 



Bpeira insularis Hentz. Island Epeirid. (PI. LII, figs. 1, 2, and 3.) 

 This spider was taken from a web stretched between trees in the 



upland forest (Sta. IV, a), Aug. 16 (No. 70). 



McCook ('89, Vol. 1, pp.117, Il8 > 2 73> 33°> 337; '90. Vol. 2, pp. 



20, 86-87, 208, 214, 289, 441, 453) records a number of interesting 



observations on this spider. The Peckhams ('87) give an account of 



their observations on its senses. 



Bpeira domicMorum Hentz. Tent Epeirid. 



This spider was taken at the margin of the low, damp forest ( Sta. 

 IV, c) Aug. 22 (No. 137) ; from the margin of a large web among 

 the branches of trees in the upland forest (Sta. IV, a) Aug. 26 (No. 

 167) ; and, on the same date, from the glade in the lowland forest 

 (Sta. IV, c), folded in a sassafras leaf (No. 173). 



I have found the species at the margin of its webs, in a leafy tent, 

 in dense woodlands near UVbana, 111., in the Brownfield woods Oct.
