72 INSECUTOR INSClTIiE MENSTRUUS 



erroneously accepted as the females of his species, is readily separated 

 from the darker form, which agrees with Zeller's male type of psammitis. 

 Thus the North American species at present must stand as follows, 

 which is the same as given in Bulletin 52, U. S. Nat. Mus., with the sub- 

 stitution of laeta for igninix. 



1. Mieza laeta Hiibner. 



= igninix Walker. 

 = crassivenella Zeller. 



2. Mieza psammitis Zeller. 



3. Mieza subfervens Walker. 



4. Mieza hasistriga Barnes and McDunnough. 



5. Mieza atrolinea Barnes and McDunnough. 



The following new species may be added to the genus: 



Mieza spatula, new species. 



Labial palpi black. Antennae black. Face bluish black. Head dark 

 brick-red. Collar light yellow. Thorax black. Fore wings black with 

 two large, bold, light yellow, longitudinal streaks, one from base of the 

 wing to termen, without, however, attaining the margin, covering the fold, 

 the dorsal part of the cell and base of veins 2 and 3, the other from the 

 middle of the cell reaches nearly to the terminal edge, attenuated towju'd 

 its base and gradually broadening out to cover veins 5-8 except at their 

 tip, the entire wing margin being black. Cilia black. Underside brick-red 

 with black costal margin. Hind wing of a clear dark brick-red color 

 above and below except the extreme costal edge, which is black. Ab- 

 domen black wth genital brushes dirty yellow. Legs black with tuft on

Habitat, Mount Peas, Costa Rica, May, Wm. Schaus, collector; 

 Cabima, Panama, May, August Busck, collector. 



U. S. Nat. Mus. type No. 1 5804. 



A very striking species, at once distinguished from other described 

 species of the genus by the black ground color of the fore wings and the 

 deep red color of the head and hind wings. 



Mieza citrina, new species. 



Labial palpi light red with blackish tips. Face and head light brick-
