and 6. Fringe metallic. Hind wing: Upper surface whitish; ter- 

 minal line narrow, buff, definition weak. 



Male genitalia (figs. 13-13b) : Symmetrical. Projection from dorsal 

 basal lobe straplike, distal curvature broad, pointed. Aedeagus 

 stout, with a short, stout tooth and numerous minute spinules. 



Female genitalia (fig. 22) : The tonguelike projection bifurcate with 

 apices blunt; median area of the bifurcation deeply and acutely angu- 

 late. Signum a long, narrow, wedgelike sclerotization. 



Type: Male, in U.S. National Museum, USNM 65005. 



Type locality : Everglades, Florida. 



Paratype: One female. Sugar Loaf Jvey, Florida. 



Food plant: An unidentified species of Gramineae. 



Remarks : The whitish facies and deep indentation of the subterminal 

 band at vein 2 oifloridalis distinguish it from discalis, which also has 

 a conspicuous fuscous discocellular patch but has a brownish facies 

 and the indentation of the subterminal band at vein 2 much weaker. 



The female paratype was reared, but it is deformed and its condition 

 is too poor for accurate determination of the alar expanse. 



Haitnhachia albescens, new species 



Figures 15, 23 



Alar expanse: Male 18 mm.; female 18-20 mm . 



Frons round. Fringe of forewing metallic. Like floridalis in 

 color and maculation but larger, with the forewings less acuminate; 

 separable from it by distribution and genitalic structures. 



Male genitalia (figs. 15, 15a): Symmetrical. Apex of dorsal basal 

 lobe rather narrow and triangular in shape; costal margin of lobe 

 with a toothlike projection near middle; the hooklike projection from 

 the lobe narrow, truncate distally and with a rounded production 

 from near base. Aedeagus with one rather short, stout spine and 

 numerous minute spinules. 



Female genitalia (fig. 23): The tonguelike projection bifurcate, 

 apices rather short, stout, blunt; median area of the bifurcation broadly 

 angulate. Two signa, one a long, narrow, wedgelike, sclerotization 

 and the other small, short, sharp, spinelike. 



Type: Male, in U.S. National Museum, USNM 65006. 



Type locality: Sioux City, Iowa. 



Paratypes: One male and three females from type locality. One 

 male and one female, Anglesea, New Jersey. One female. Cape 

 Henry, Virginia. 



Food plant: Unknown. 



Remarks : The male genitalia of albescens resemble those oifloridalis, 

 but in the latter the production of costa of the dorsal basal lobe is 

 broader apically, without a toothlike projection near middle of the
