ENTOMOSTRACA OF MINNESOTA. 309 



claws and two short setae; one of these setse is located at the disto-eutal 

 angle and the other at the disto-ectal angle of the joint. The claws 

 are smooth. 



In the male the antenna is six jointed, and the terminal claws are 

 longer and more flexible than in the female. 



Mandible resembles that of Cypria exculpta Fischer. 



First foot of female (Fig. 5) long and slender, composed of five 

 joints. The most proximal joint large, the broadest of all. The next 

 joint the shortest of all. The antepenultimate joint about as long as 

 the most proximal, but more slender. From the margin of this joint 

 arise two short setae. From the disto-caudal angle of this joint arises 

 a long seta which extends to beyond the base of the terminal claws. 

 From near the distocephalic angle of this joint arises a short seta. 

 Along the cephalic margin of the penultimate joint there is a longi- 

 tudinal row of fine hairs. From the disto-caudal angle of this joint 

 arises a seta of medium length. From the extremity of the terminal 

 joint arises a long claw; this claw is much longer than the joint and 

 appears to be composed of two portions; a short proximal and a long 

 distal portion. From the cephalic margin of the proximal portion 

 arises a short seta. 



Second foot of female (Fig. 6) composed of five joints, the joints 

 diminishing in size from the second to the most distal joint. The most 

 proximal joint bears at about its proximo-caudal angle a long plumose 

 seta which is as long as the joint; and from the distal third of its 

 cephalad margin arises a somewhat shorter seta. From the distal 

 fourth of the cephalic margin of the antepenultimate jointarises a seta. 

 From a corresponding point on the penultimate joint there also arises 

 a seta. From the extremity of the terminal joint arise two long and 

 two short sette. The two long setae are about as long as the entire 

 limb. 



The two shorter setae are but little longer than the terminal joint. 



Post-abdomen (Fig. 7) is curved, bearing one terminal claw and at 

 its base a short terminal spine. On the convex surface there is a sub- 

 terminal claw. 



Verticillate sac (Fig. 8) of male as usual in this genus. It seems to 

 be enclosed by a transparent capsule. 



Habitat: This species is abundant among the grass and weeds of 

 many shallow ponds. It has been found at the following places: 

 Cincinnati, Ohio (Turner, 213); Atlanta, Georgia (Turner, 215); Fay- 

 ette County, Georgia (Turner, 216).
