The anal legs in the male are short. Fourth article considerably 
thickened, more so than in voracior; dorsal or dorso-mesal surface con- 
spicuously bowed ventrad or depressed over middle and posterior 
portion, or the depression often almost strictly mesal, longitudinally 
furrowed along depressed surface; also longitudinally furrowed along 
dorsal surface toward ectal edge of latter. Third and fourth articles 
rather deeply sulcate longitudinally on ventral surface. Tibia longi- 
tudinally furrowed dorsally. Tarsal joints not clearly sulcate mesally. 
Penult legs very similar to anal but the fourth article but slightly 
enlarged and not at all excavated meso- or caudo-dorsally, though the 
dorsal longitudinal furrow is conspicuous. 
The single article composing the gonopod of male well exposed; 
directed caudo-ectad; sides nearly parallel; distally subtruncate; 
bearing mostly about four bristles. In the gonopods of the female the 
claw is comparatively short; strongly bent; tripartite, the three lobes 
distinct, the median being considerably larger much as in vorax but not 
so greatly exceeding the lateral as in mordax, etc. Basal spines stout 
and moderately long; mostly uniformly attenuated from base to apex. 
Mesal side of first article straight, diverging cephalad from mesal 
side of fellow but little. 
Body appearing to vary considerably in relative width, the length 
being mostly as much as eight times longer than width of tenth plate, 
but in some falling a little below this (7.75) and in others as much as 8.4 
times longer. Moderately attenuated cephalad from eighth plate, 
with the first plate a very little wider than the third and usually a little 
narrower than the head, occasionally as wide as latter; the average 
ratio of widths of head, first and tenth plates is 30: 29:35. In one male 
the widths of head and first, se eighth, tenth and twelfth dorsal 
plates stand to each other as 72, 72, 70, 78, 78, and 72. 
Length from 18 to26mm. A male 25 mm. long has antennz about 
12.5 mm. long, anal legs 8.5-9 mm. long and the tenth dorsal plate 
2.9 mm. wide. 
Locality: Jackson, Alabama (author, 1910). 
This species is very close to the next, L. voracior. Usually 
both sexes of fully grown specimens of these species are to be 
distinguished quite readily by the form of the coxal pores 
eleventh 
the anterior or ectal dorsal 
small; of anal the claw single.
