 and Plum Island. Adult males in June and July, Cold Spring Harbor, 

 Long Island, N. Y., Miss Bryant. 



Lathys foxii = Prodalia foxii, Marx. Ent. Soc. Washington, 1891. 



2 mm. long. Pale, with the cephalothorax a little darker than the 

 abdomen. Abdomen marked with a middle row of brown angular 

 marks that in some individuals join a row of spots along the sides. 

 PI. IV, fig. 5. In the male the dark marks are wider so that there 

 appear to be light marks on a darker ground. The front row of 

 eyes is shorter than the upper row and the front middle e3'es much 

 smaller than the others. PI. IV, fig. 5e. The sternum is nearly as 

 wide as long, with a blunt point behind which extends between the 

 fourth coxae. The cribellum is small and undivided. Fig. 5 a. 



The male palpi have the patella and tibia both very short. The 

 patella is widened at the end so that seen from above it is twice 

 as wide as at the base. The til^ia is also widened at the end and 

 has a groove above in which rests the end of the tube of the 

 palpal organ, which extends along the outer side of the tarsus and 

 turns inward and upward between tarsus and tibia. Fig. 5 d. 



Under leaves at all times in summer and autumn. Males from 

 Mollis, Me., June 12. Females from Old Orchard Beach, Me., Holden, 

 Carlisle, Huntington, Williamstown, Mass., Kent, Conn. 



Pisaura brevipes, new. 



A smaller and dark form of Pisaura formerly placed with P. iindata. 

 It is one-sixth smaller than undata and dark brown even when small 

 and freshly molted, and the middle stripe has nearly straight sides, 

 both on cephalothorax and abdomen, with a bright white line along 

 its edges. The sides of cephalothorax and abdomen are dark brown. 

 The legs are brown without rings. The first leg is shorter than 

 the fourth and without the femur is shorter than the bod}', while 

 in P. iindata the first leg without the femur and patella is as long 

 as the body. PI. IV, figs. 6, 6 b. The epig3'num is slightly shorter 

 and rounder than in undata. Figs. 6 a, 6 c.

 The male is 8 mm. long, the cephalothorax 5 mm. long, the fourth 

 leg 14 mm. and the first leg 13 mm. The cephalothorax shows no 

 markings in alcohol, and the legs have no spots or rings, but are 

 irregularly strijoed lengthwise as in Pardosa glacialis. The male
