 ending beyond the fork of R 2+3 ; r removed from the tip of i?j ; Rs square at its 

 origin and at the angle with a very long spur that is longer than R 2+3 ; 7? 2+ 3 

 a little longer than the basal deflection of Cu t which is inserted before the 

 fork of M ; petiole of cell M t a little longer than R 2+3 ; 2d A long, ending oppo- 

 site the base of the sector; second anal cell moderately broad. 



Abdomen elongate, the tergites dark brown ; sternites dull yellowish with 

 the segments ringed subbasally and more narrowly apically with brown ; valves

 subacute. 



Habitat: Panama (Darien). 



Holotype, J, Quebrada Richa, a branch of the Rio Tapaliza, a 

 branch of the Rio Pucro, Department of Panama, altitude 1300 feet, 

 July 24, 1918 (Axel Olsson). 



This interesting species is allied to L. cpipJiragmoidcs Alex. 

 (Brazil), but is readily separated by the diagnostic characters 

 given above.
