and the maxillse and labium are darker than the sternum and 

 coxse, the tarsus and metatarus of legs III and IV are also a little 

 darkened. On the upper side the cephalothorax is lighter in the 

 middle without any distinct middle stripe. The abdomen is 

 faintly marked with a series of dark and light transverse stripes. 

 The mandibles are dark brown, black at the ends with orange 

 hairs on the front. In young the femora are brighter yellow and 

 the tibia and metatarsus of legs I and II are black above as well 

 as below and in the adult male these joints are dark above though 

 not as black as on the under side. 



The burrowing habits of this species have been well described 

 by Hancock in his account of L. domifex. The holes are made 

 usually in sand but are sometimes dug in soil of any kind. I found 

 two at Durham, North Carolina, in hard clay soil. There is usu- 

 ally a turret of some kind unless in open sand where there is no 

 material for one. Fig. 4 shows the top of a hole at Buffington, 

 Indiana, with a turret partly covered with leaves of the bearberry. 

 The species matures in August and September and I have a male 

 taken by Mr. A. G. Vestal at Havana, 111., among litter on the 

 ground as late as October 10. The eggs are laid in May, rather 

 later than those of wrightii. One dug at Durham, North Caro- 

 lina, early in July had young on its back. 



This species is very abundant in the sand dune country along 

 the Great Lakes. I found them at Sandusky, Ohio, near the sum- 

 mer laboratory of the University of Ohio, and they are common 

 all through northern Indiana and Illinois. It does not mix its 

 burrows with those of wrightii but each species lives in colonies 

 of its own. R. V. Chamberlin reports it from Utah and L. lati- 

 frons Montgomery, Proc. Acad. Nat. Sci., 1904, from Texas, is 

 said by Banks to be the same species. 



In his account of L. fatifera, Hentz, in Boston Journ. Nat. Hist., 

 1841, mentions "a piceous variety" pale on the under side, which 

 is probably this species.

Although no description of it has been published, this species 

 has long been known. J. L. Hancock in his account of L. domi- 

 fex mentions several species of burrowing spiders in the neighbor-
