median buff stripe (white at its anterior end) arising as a narrow band 

 in the eye area, enlarging between this region and the dorsal groove, 

 largest around the dorsal groove (where its greatest diameter about 

 equals the width of the eye area), and narrowed again behind the 

 dorsal groove. To each side of the anterior part of this band, parallel 

 to it and median to each eye of the third row, is a much narrower buff 

 line. From the dorsal groove deep brown lines radiate to a submar- 

 ginal. dentated buff band. Sternum black. Abdomen above with a 

 black-edged, brown median band which terminates bluntly about the 

 middle of the dorsum and is laterally dentate; behind this band are 

 three or four transverse arches, each blackish anteriorly and whitish 

 posteriorly, and between these arches are black spots in transverse 

 rows; the rest of the dorsvun is yellowish spotted and streaked with 

 dark brown. The sides are buff, the whole venter deep black. Epi- 

 gynum reddish-black. Chelicera, labium and maxillce deep blackish-red. 

 Legs above yellowish, femora I and II with an indistinct darker longi- 

 tudinal band on tlie median side, femora III and IV spotted with 

 brownish, fourth pair of legs with a black ring at ench end of the tibia 

 and at the distal end of the metatarsus, these black markings l^eing 

 much more distinct on the ventral surface. Ventral surface of the 

 coxae brownish-yellow or deep black. 



One female (the largest obtained) differed in coloration as follows: 

 Cephalothorax chocolate-brown with the cheeks pale buff, this buff 

 extending back as a narrow submarginal band to about the end of the 

 anterior third of the cephalothorax, and succeeded by three to four 

 indistinct buff spots. 



Color of Males (in alcohol). — Differ from the females in that the 

 median stripe on the abdominal dorsum is much more distinct, and 

 with a buff band contiguous to each side of it. Sternum, labiiuii, 

 maxillae and inferior surface of coxae chocolate-brown. 



Com'parisons. — This species comes closest to L. inhonesta (Keys.), 

 from which it differs: (1) In the first row of eyes being upon the 

 clypeal margin; (2) in the head being relatively lower at the second 

 row of eyes; (3) in the head of the female being rounded in front; 

 (4) in the color of the abdominal dorsum; and (5) to some extent in 

 the genitaUa. 



Habits. — Under stones, common in the autumn, but none found in 

 the winter.
