ter of the web; and from webs in the shady lowland forest (Sta. 

 IV, c) Aug. 26 (No. 172). 



Montgomery ('03, pp. 1 19-120 and '09) has made observations 

 on the breeding habits of this species, and McCook ('89, Vol. i, pp. 

 64, 73, 125-127, 254, 338, and '90, \'ol. 2, pp. 285, 289, 375) describes 

 its webs and gives observations on its habits. 



Lycosid^ 



Lycosa scutulata Hentz. 



A single immature specimen was taken from the low vegetation 

 in an open glade in the lowland part of the ^Bates woods (Sta. IV, c) 

 Aug. 22 (No. 144). 



For the breeding habits of this species see Montgomery ('03, 

 pp. 72-76). 



Lycosa sp. ; young. 



This spider was taken in the upland woods (Sta. IV, a), running 

 upon the ground, Aug. 23 (No. 150). Another undetermined species 

 was taken in the pathway entering the upland forest from the cleared 

 area (Sta. IV, a). This spider was dug from a burrow about two 

 inches deep, in the solid clay of the pathway, Aug. 22 (No. 142). 



ACARINA 



Erigphytd^ 



Acarus serotince Beut. Cherry-leaf Gall-mite. (PI. LV, fig. i.) 



This small mite was taken in the lowland portion of the Bates 

 woods (Sta. IV, c) Aug. 20 (No. 116). It forms a gall on the upper 

 side of the leaves of the wild cherry, Pruniis serotina. 



INSECT A 



Platyptera 



Termitid^ 



Termes flavipes Koll. White Ant. Termite. (PI. LV, fig. 2.) 



A small well-decayed stump in the upland forest (Sta. lY, a) was 

 found Aug. 17 to contain a colony of these termites in large num- 

 bers — mainly workers but also some soldiers (Nos. ^2, 79). In close 

 proximity was a colony of the ant Aphccnogaster fulva. Some of 

 these ants (Nos. 74-76) w^ere observed to pick up termites and carry 

 them away as they do their own young when a nest is disturbed. A.
