25. Cucullus of harpe fairly evenly expanded beyond base to present subsymmetri- 



cally capitate appearance (fig. 112), costa of harpe with considerable dorsal 

 expansion caudad of point of attachment of arm of transtilla (fig. 112); 

 vesica of aedeagus armed along dextral margin with irregular row of 

 approximately 18 minute, weakly sclerotized, indistinct cornuti unequal 

 in size (figs. 114, 115); wing expanse approximately 16 mm.; Florida, 



Texas 22. piger (Dyar) 



Cucullus of harpe broadly and unevenly expanded ventrad beyond base to 

 present asymmetrically capitate appearance (fig. 118), costa of harpe with 

 only very slight dorsal expansion caudad of point of attachment of arm of 

 transtilla (fig. 118); vesica of aedeagus armed about perimeter with approxi- 

 mately 15 variously sized, well sclerotized, distinct cornuti arranged in 

 form of incomplete oval (figs. 119, 120); wing expanse usually greater than 

 16 mm.; Texas, Arizona 23. vanduzeei, new species 



26. Cucullus of harpe with major portion directed considerably ventrad (figs. 



122, 125) and with apical margin markedly dentate (fig. 122) or produced 

 into at least one large, acute, spinelike process (fig. 125) ; {kearfotti-pseudo- 



hirsutus species group) 27 



Cucullus of harpe with or without major portion directed considerably ventrad 

 but with apical margin neither dentate nor produced into spinelike 

 processes 28 



27. Cucullus of harpe with central portion of ventral margin roughly dentate, 



with apical portion somewhat expanded; with apical margin dentate, pro- 

 duced into 5 to 10 teeth of various sizes, ventral tooth often the largest 

 (fig. 122); wing expanse 17 to 21 mm. . . 24. pseudohirsutus, new name 

 Cucullus of harpe with central portion of ventral margin not dentate, with 

 apical portion somewhat narrowed; apex of cucullus emarginate, with 

 dorsal extremity in form of subtriangular projection, with ventral extremity 

 produced into large and elongate process directed strongly mesad (fig. 125) ; 

 wing expanse 22 to 29 mm 25. kearfotti (Dyar) 



28. Uncus bifid but with furcae closely appressed and often superficially appear- 



ing as single process with median longitudinal suture (fig. 131); (furcatus- 



pundellus species group — relationship not exceedingly close) 29 



Uncus simple, with uncal process not appearing to have median longitudinal 

 suture (figs. 138, 143) 30 



29. Cucullus of harpe with apical portion considerably expanded and directed 



dorsad (fig. 127); aedeagus elongate and slender (fig. 128), with base mod- 

 erately expanded laterad and ventrad (figs. 128, 129); vesica of aedeagus 



unarmed (figs. 128, 130) 26. furcatus (Walsingham) 



Cucullus of harpe with apical portion expanded and directed ventrad (fig. 

 132); aedeagus of medium length and width (fig. 133), with base broadly 

 expanded laterad into pair of subdigitate processes (figs. 133, 134); vesica 

 of aedeagus armed with several cornuti (figs. 133, 134). 



27. punctellus (Busck) 



30. Cucullus of harpe directed considerably ventrad, with major apical portion 



broad, with dorsal and ventral margins approximately linear and parallel, 

 with apex truncate or nearly so (fig. 139) ; gnathos as a rule armed laterad 

 near apex with pair of small, acute, toothhke processes (figs. 142, 143) ; 

 vesica of aedeagus with free portion broader than and almost as long as 

 aedeagus (fig. 141) or slender but longer than aedeagus, often twisted or 



spiraled 28. cockerelli (Dyar) 



Cucullus of harpe partly (fig. 135) or entirely unlike above; gnathos unarmed 

 (fig. 138) ; vesica of aedeagus with only small free portion 31
