brown without any rings or otlier markings. In the middle of tlie 

 ce])halothorax is a longitudinal stripe about a third its width, of the 

 same color as the legs. The sides of the cephalothorax are light 

 yellow, darkest toward the edges. The brown middle stripe contin- 

 ues along the abdomen with the edges a little irregular but with no 

 distinct teeth or undulations. Young individuals have all the colors 

 lighter and yellower, the legs more or less ringed and the middle 

 stripe of the abdomen distinctly undulated. Along the edges of the 

 middle stripe there is usually a fine white line which is sometimes 

 broken up into a row of spots, as in Hentz's 31. earolinensis. In very 

 young spiders the abdominal stripe is distinctly serrated, as in Hentz's 

 31. serrata, the stripe on the thorax divided into two and the whole 

 body less flattened. 



The male pali)i are long. The tarsus is pointed but nearly as wide 

 as long. The middle process of the palpal organ is flat and thin, 

 spreading out over the greater part of the bulb. At one side it is 

 narrowed into a fine point which supports the end of the long slender 

 tube, the ends of both resting on a short process at the base of the 

 bulb. On the under side of the end of the tibia is a wide flat 

 process extending up to the palpal organ, and on the outer side is a 

 long tooth slightly notched at the end. 



From July to September the females may be found under large 

 bunches of web four or five inches across, in grass or low bushes in 

 meadows. The cocoon is placed in this bunch of web, and the young 

 after hatching scatter themselves through it.

In this genus the cephalothorax is about as wide as long, and 

 rounded on the back, with but little separation between the head and 

 thorax. The head is wide and nearly straight in front. The front 

 row of eyes is composed of four small ones as in Lycosa. The 

 second row are larger, but not larger than those of the third row, 

 which are twice as far apart and a little farther back. The legs are 

 long, and the first, second and fourtli, are nearly e(iual in length. Tlie 

 feet are thickly covered with fine hairs. The abdomen is a little flat- 

 tened and a little pointed behind. The tibia of the male palpus has 

 a large process on one side. They live near water on which they run 

 easily. The female carries the cocoon in her mandibles until the 

 young are ready to hatch, and then fastens it in a l)ush with many 

 irregular threads, among which the young remain a short time after 

 leaving the cocoon.
