Related to L. triacanthos Alexander, L. laticincta Alexander, and 

 similar species, in the trichiation of the legs, differing conspicuously 

 in the venation and pattern of the wings. 



Legs with the coxae conspicuously pale against the dark pleura; 

 trochanters pale; femora brown, the fore femora with about the apical 

 third or a little more dark brown, provided with conspicuous, out- 

 spreading setae; on the hind legs the dark tips are much narrower, 

 occupying approximately the distal fifth; tibiae dark brown with a 

 conspicuous subbasal yellowish white ring; basitarsi yellowish white, 

 the tips narrowly darkened; remainder of tarsi dark brown. Wings 

 somewhat teneral, very pale brown, with a sparse darker brown pattern 

 that is apparently confined to the vicinity of the veins; a compara- 

 tively small area at origin of Rs; conspicuous seams along the cord 

 and outer end of cell ist M2, and small spots at end of vein R2 and 

 fork of vein M1+2; veins dark brown. Venation : Sci ending opposite 

 r, Sc2 far from the tip of Sci, immediately distad of the origin of 

 R4+5; r on i?2 about three times its length beyond the fork; Rs very 

 long, about three times R2+3; deflection of i?4+5 comparatively short, . 

 arcuated, about twice the length of r-m; pétiole of cell M\ longer than 

 the cell; cell ist M2 irregularly hexagonal, the first section of M3+4 

 about equal to Ms+Cui.

 lacking; basai deflection of Cu\ before the fork of M.
