and Psaroyiius obscurus Fabricius are common and widely distrib- 

 uted throughout the tropics of the New World, this work of 

 breeding out the adults should not be very difficult. 



The following corrections to my paper cited above shoul 1 be 

 made: Lecteria conspersa Enderlein is a Limnophila though not a 

 member of the subgenus Dadylolabis as stated by its describer. 

 L. mattogrossae Alexander (ibid., 496, 497) and armiUaris Fabricius 

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

 species are Psaronii and may be separated by means of the key 

 given later. 



Psaronius fuscipennis sp. n. 



Wings dark fuscous with darker and paler markings in the radial cells. 



Male. — Length, 27 mm. ; wing, 18.8 mm. 



Female. —'Length., 24 to 25 mm. ; wing, 16 to 16.2 mm. 



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

 ation is very much darker. The body markings are dark brown instead of the 

 ochraceous brown of obscurus; the four terminal tarsal segments uniformly 

 brown, not pale tipped with brown. The wings are distinctly dark brown 

 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.
