Patellae of first and second pairs of legs armed in front with a short 

 spine. Tibia + patella of first legs about equalling the cephalothorax 

 in length; tibia + patella of fourth legs clearly longer than the cephalo- 

 thorax and also longer than the metatarsus of same legs. 



Chelicene armed as usual, the three teeth of lower margin stout. 



The cpigynum having the general form and structure of that of L. 

 helluo (PI. XVII, fig. 1); septum widest anteriorly, its sides nearly 

 straight ; transverse arms rather thick. 



Total length, 13.5 mm. Length of cephalothorax, 6.3 mm.; width, 

 4.8 mm. 



Length of leg I, 19.3 mm. ; tib. + pat., 6.2 mm. ; met., 3.8 mm. 



Length of leg II, 16.2 mm. 



Length of leg III, 16.2 mm. 



Length of leg IV, 23.5 mm. ; tib. + pat., 7 mm. ; met., 6.7 mm. 



Male. — Coloration as for the female; but the markings more distinct. 



Palpal organ of the general type of that of L. helluo (PI. XVII, 

 fig. 2). The auricula conspicuous, more strongly chitinized than 

 usual, dark in color, turned outward apically. Principal tenaculum 

 relatively shorter, and more outwardly directed than in helluo. 



Total length, 13 mm. Length of cephalothorax, 6.8 mm.; width, 

 5 mm. 



Length of leg I, 20.7 mm. ; tib. + pat., 7 mm. ; met., 4.8 mm. 



Length of leg II, 19.1 mm. 



Length of leg III, 19.1 mm. 



Length of leg IV, 25.4 mm. ; tib. + pat., 7.8 mm. ; met., 7.6 mm.

 (Can. Entomologist, p. 286.) 

 Female. — Cephalothorax dark brown; a pale narrow median line 

 extending backward from first eye row, widening abruptly in front of 

 dorsal groove, and then gradually narrowing to a point at posterior 

 margin; a broad light-colored marginal stripe on each side not extending 

 forward farther than the third eye row, its upper margin coarsely 

 dentate, the lower border broken by a few dark dots, but not limited
