NcpotulUf new genus 



Figures 2, 16, 61 



Type-species: Nepotula secura Hodges, new species. 



Head: smooth-scaled; labial palpus almost attaining vertex, third 

 segment shorter than second, apex acute; tongue moderate; maxillary 

 palpus folded over base of tongue; antenna two-thirds length of 

 forewing, simple, ciliate, pecten absent (one specimen examined, 

 possibly deciduous). Forewing: broadly lanceolate, apex acute; 

 12 veins present; lb furcate basally; 2 extremely faint basally; 4, 5, 

 and 6 equidistant basally; 7 and 8 stalked. Hind wing: lanceolate, 

 apex acute; 8 veins present; 6 and 7 separate. Male genitalia: 

 valva sublinear, costal area a broad fold; vinculum narrow; tegumen 

 relatively broad; uncus present, short, heavily sclerotized; a lightly 

 sclerotized area on under surface of tuba analis. Female genitalia: 

 not known. 



Nepotula is closest to Walshia but differs from the latter in having 

 a heavily sclerotized uncus and a relatively broad tegumen. 



Nepotula secura, new species 



Figures 17, 61 



Labial palpus, tongue, maxillary palpus, head, and thorax covered 

 with scales which are buff basally and apically , brown-black medially ; 

 apices of second and third segments of labial palpus buff -white; 

 undersurface of scape of antenna buff, upper surface and shaft brown- 

 black. Forewing: brown-black along costal margin, becoming pale 

 apically; fascia of brown-black scales at one-fourth from costa to 

 fold, continued beyond fold as series of raised scales; basal one-half 

 of wing uneven tawny-buft" becoming paler apically and gradually 

 merging with pale brown-black of apex; three patches of brown-black 

 raised scales at one-half, two costad of fold, and one from fold to 

 dorsal margin; series of patches of brown-black raised scales along
