The following corrections to mj' paper cited above shoul.i be 

 made: Lecleria conspersa Enderlein is a Limnophila though not a 

 member of the subgenus Dadylolabis as stated by its describer. 

 L. mallogrossae Alexjuider (ibid., 49(5, 497) and armillaris Fabricius 

 (ibid., 497) are members of Lcdcria as above restricted; the other 

 species are Psaronii and may bo soparnted by means of the key 

 given later.

Similar to P. obscurus in size and general structure but the body color-

 with darker markings at the origin of Rs and at the stigmal spot; paler, 

 subhyaline, blotches before and after the origin of Rs and beyond the stigma.
