LIMOSINA. 181 



Like L. fungicola ; marginal and submarginal areolets much narrower; 

 transverse veins less distant. Legs sometimes entirely ferruginous ; in 

 others the femora and the middle of the tibiae are pitchy, or the legs 

 are blackish, with the knees and tarsi ferruginous. Wings brownish, 

 with distinct brown veins, the costal vein not incrassated. It differs from 

 L. clunipes by the wings, by the second joint of the hind tarsi, which is not 

 thickened^ and by other characters.
