groove. The abdomen is mottled with black and yellowish ; there is 

 usually a light median stripe containing a shorter dark stripe, and 

 several light spots on the sides, but these markings are not at all 

 distinct. Beneath there is a median black band on the abdomen. 

 The legs are shining like the cephalothorax, and are short. Length 

 of female, 10 mm. 



This species I have taken only in York County, Penn. It is 

 found under stones, but does not seem to be common. 



L. frondicola Emerton. (PI. XV. figs. 2, 2a, 2b.) 



Above, cephalothorax brown with a broad gray central band as 

 wide as the posterior pair of eyes. A bdomen gray with two dark 

 spots on the anterior end, which are prolonged into bands on the 

 sides. There are two black dorsal spots and sometimes a short me- 

 dian stripe as shown in Emerton's figure (Trans. Conn. Acad., vol. 

 VI, pi. XLVI, fig. 3.) but in nearly all my specimens this stripe is 

 obsolete. The under side of the abdomen is marked with a broad 

 black band. Length of female 14 mm. 



This species I have usually found running among dead leaves in 

 woods, it is rather common about Philadelphia and has also been 

 taken in York Co., Penn. 



L. kochii Keys. (PI. XV, figs. .3, 3a .3b.) 



Above, cephalothorax brown with a gray median stripe as broad 

 as the eye area, strongly indented on each side just in front of the 

 dorsal groove. There are also indistinct submarginal bands. Ab- 

 domen gray with two black spots on the anterior end which are fol- 

 lowed by several pairs of irregular dorsal spots and occasionally a 

 short median stripe. Beneath gray with minute black dots usually 

 arranged in four longitudinal lines converging at the spinnerets. 

 Legs gray slightly banded on the femora. Length of female 14 mm. 



This species closely resembles the preceding but may be distin- 

 guished by the band on the cephalothorax being incised about the 

 middle. 



It is common in the vicinity of Philadelphia being found under 

 stones in woods. It has also been taken in Chester Co., Penn., 

 and at several localities in New Jersey. 

 L. communis Emerton. 



Above brown, cephalothorax with a light central band as broad 

 as the eyes, and light lateral bands. Abdomen with a broad light 

 median band coming to a point at the posterior extremity just above
