Hyalospila ptychis, new species. 



Fore wing gray at base of costa, white over the cell, the inner 

 half and terminal area shaded with reddish violet; inner line 

 lost; a black point in the submedian fold; discal dots black, 

 separate, round; outer line slender, reddish, waved, incised 

 and broken in submedian fold ; a terminal row of minute black 

 dots. Hind wing translucent, veins and termen gray. Ex- 

 panse, 14 mm. 



Type, male. No. 31951. U. S. Nat. Mus. ; Santiago, Cuba, 

 June (W. Schaus). 



y Homalopalpia columnella Zeller. 



Myelois columnella Zeller, Hor. Ent. Soc. Ross., xvi, 209. 1881. 



Ragonot places this in Piesmopoda, having no male. The 



male has the same sexual characters as H. dalera Dyar, and I 



am not certain that the species are distinct. H. columnella 



seems somewhat larger. 



Homalopalpia paranensis, new species. 



Male as in H. cohimnella and dalera, but the basal joint 

 of the antennae is brown instead of pale bufif and has a smaller, 

 less conspicuous notch. Fore wing with the base dark brown, 

 the following pale band with a sharp curved yellowish edge, 

 much as in the following species; outer line finely denticulate, 

 also as in the following; the palpi, however, are broadly thick- 

 ened with dark brown hairs as in columnella. 



Type, male, No. 21952, U. S. Nat. Mus.; Castro, Parana, 

 Brazil (Schaus collection). 



v^ Homalopalpia nerthella Schaus. 



Piesmopoda nerthella Schaus, Ann. Mag. Nat. Hist. (8). xi, 247, 



1913. 

 Homalopalpia euthales Dyar, Proc. U. S. Nat. Miis.. xlvii, 40:5, 

 1914. 

 The type of nerthella is a female, of euthales, a male, seem- 

 ing at first sight quite distinct. I am satisfied that the differ- 

 ences are only sexual.
