30 Psyche [April 



the abdomen are black and sometimes in young individuals the 

 middle and side stripes unite and the whole under surface is as 

 black as in wrightii. 



In males the upper side is all light gray, the front legs only a 

 little darker than the third and fourth. The front of the mandi- 

 bles is more brightly orange, with sometimes a little orange around 

 the eyes, and there is a bright orange marking bordered with 

 black in the middle of the abdomen. The light middle stripe of 

 the cephalothorax is bordered by black markings radiating toward 

 the sides, the most conspicuous marks ending at the two upper 

 eyes. On the under side the markings are like those of the female, 

 with still stronger contrast between the light and dark parts. 



The length of the cephalothorax of the female is 9 mm., of the 

 male 8 mm. Leg I of female 20 mm., of male 22 mm. 



The holes are usually in clear sand, but where the spiders are 

 numerous they dig on high land among low plants, and some- 

 times even in pastures where there is a thick sod. They make 

 no "turret" around the mouth of the hole, but where they dig 

 among loose rubbish, a few pieces may be sometimes fastened to 

 the lining around the mouth. A flat collar on the sand is some- 

 times made around the hole. The spider sits out on the edge of 

 its hole when looking for prey with feet I and II turned under the 

 thorax, as shown in Fig. 2. Insects are noticed within six or eight 

 inches and the spider rushes for them, returning quickly to the 

 hole. 



Freshly molted males and females are found in their holes in 

 August and the males wander about on the surface through that 

 month and September. The pairing was once seen at the mouth 

 of the hole. The female sat out of the hole with her feet under 

 her as usual, while the male apjjroached very slowly, holding his 

 first legs above his head and alternately moving them slowly for- 

 ward and drawing them quickly back until he was within the 

 female's reach, when she came out toward him and after a show 

 of defence, allowed him to step over her and grasp her around 

 the cephalothorax as usual in the Lycosidse. The eggs are laid 

 the next spring in May and June. The young remain a long time 

 with the mother, in one case as late as September. 



This species lives from Old Orchard Beach, Maine, to Sandy 

 Hook, New Jersey, but never far from the seashore. It is espe-
