XII. — New England LYcosiDyE. By J. H. Embkton. 



The Lycosidte have the abdomen .iiid usually the cephalothorax 

 considerably longer than l)road and the legs long, the fourth [)air 

 longest, with long movable spines. The feet have three claws, the 

 lateral ones long with numerous teeth, and the middle Qne short with- 

 out teeth or with only one or two. The tarsi are sometimes thickly 

 covered with hairs concealing the claws, but there are no toothed 

 hairs under the claws as in the spiders that live in webs. 



The eyes are in three rows. The front row consists of four small 

 eyes nearly of the same size, the second row of two large eyes on the 

 front of the head and the third row of two eyes a little smaller than 

 the last, a little farther apart and farther back on tlie head. 



The body is hairy all over and a large part of the markings are 

 formed by colored hairs and change considerably when the spider is 

 wet. The markings consist usually of three longitudinal light lines 

 on the cephalothorax, different parts of which are obscured in differ- 

 ent species, and a middle stripe of various shapes on the abdomen. 



The palpi of the males are comparatively simple. The patella and 

 tibia are but little modified except in Doloraedes. The tarsus is long 

 and pointed. The tube of the palpal organ is usually short and lies 

 across the middle of the bulb. On the middle or base of the bulb is 

 a large process, the shape of which distinguishes many species. The 

 external part of the epigymim consists usually of a middle lobe 

 widened at the end and hard side lobes. 



The Lycosidffi live on the ground, running after their prey and mak- 

 ing no cobwebs. Several species make holes in the ground, which 

 they line with silk and use for shelter but not as traps. 



The females carry the cocoon attached to the spinnerets and the 

 young mount on the female's abdomen and are carried for a time after 

 leaving the cocoon. 



Dolomedes and Ocyale carry the cocoon in their jaws and spin a 

 large irregular web in bashes for the use of the young. 



Many of the species of Lycosidae are very difficult to distinguish, 

 and I have been unable to identify many of them with published de- 

 scriptions. I have compared mine with a large collection of European 

 Lycosidae and find very few species common to both countries. The 

 following papers contain descriptions of Aiuerican Lycosidae.
