LEPTOCELLA DIMINUTA, sp. nov. 

 TYPE M. C. Z. 10,900. British Guiana: Bartica (H. S. Parish). 



Whitish, clothed with white hairs, tips of antennal joints barely dark. 

 Fore wings clothed with white hairs and with many black scales through the 

 middle area, forming a more or less distinct slightly curved stripe from near 

 base to toward the tip. Wings rather short, third fork with a pedicel very 

 much shorter than that to first fork. The male genitalia has the superior 

 median plate short, the superior appendages long, slender, not enlarged at tip, 

 and often curved downward, the inferior appendages are slightly sinuous, and 

 almost pointed at the tip. 



Expanse 12 to 14 mm. 



LEPTOCELLA SPARSA, sp. nov. 

 TYPE. M. C. Z. 10,899. Argentina Misiones (Jorgensen). 



Body is yellowish, clothed with white hairs; tips of antennal joints dark. 

 Wings with mostly whitish scales on basal part; near middle are three rather 

 yellowish bands, each outlined by black scales, and between them silvery white ; 

 in the region of the anastomosis mostly silvery, with numerous black dots 

 tending to form lines or elliptical figures; near the apex are two silvery bands, 

 rest of apical part yellowish, the usual marginal black patch contains four pale 

 spots. The first fork is only a little longer than its pedicel, the third fork with 

 a pedicel about as long as the width of the discal cell. The superior male 

 appendages are cylindrical, but enlarged and truncate at tip, not distinctly 

 emarginate. 



Expanse 24 mm. 



This is probably the species figured by Dr. Ulmer as L. gemma.

 beyondxand connected to it; and before the stigma an oblique band and a 

 part of another starting from hind border; sometimes there is more yellow in 

 the basal portion; venation about as in other species, the discal cell does not
