9 genitalia. Corpus bursae with broad, scobinate area ventrally on left side and elongate 

 signum dorsally on right side. Duct between corpus bursae and appendix bursae strongly 

 scobinate. Ductus bursae sclerotized except for transverse area just posterior to its mid-point. 

 Paired lamellae antevaginalis and medially emarginate lamella postvaginalis present. Posterior 

 apophyses longer than anterior apophyses. Scent tubules tapered anteriorly. 



$ genitalia. Juxta globular. Costal region of valve terminating apically in heavily 

 sclerotized, inwardly directed process. Uncus weakly sulcate mid-dorsally; apex acuminate, 

 ventrally directed. 



A mostly white species with a conspicuous black line along the dorsal surface 

 of the abdomen and areas of bright orange-red on the legs. 

 Known only from Surinam and French Guiana. 



Material examined.

EMURENA gen. n. [Gender: feminine] 

 [Automolis Hiibner sensu auct. Partim.] 

 Type-species: Emurena femandezi sp. n. 



(J, $. Palp extending to near middle of clypeo-frons ; terminal segment minute. Head 

 without scale-tufts. Antennae serrate in femandezi and lurida, biserrate in remaining three 

 species; apical segments paler in colour than rest of flagellum. Patagia mainly yellow; tegulae 

 yellow, or yellow and grey; rest of dorsal surface of thorax yellow or grey. Tymbal organ 

 present; with about 60 grooves in femandezi and lurida, 50 in other three species. Mesothoracic 

 leg with one pair of spurs; metathoracic leg with two pairs of spurs. Forewing yellow, with 

 weakly iridescent, grey markings on upper surface; strongly marked on under surface in 

 tripunctata and quinquepunctata, weakly marked in remaining three species. Forewing venation 

 as in Text-fig. 15. Hindwing yellow. Male of femandezi with two androconial zones: one on 

 the greatly enlarged costal area of hindwing, the other under that part of the forewing overlapped 

 by costal area of hindwing (Text-figs 15, 16). Males of femandezi, tripunctata and quinque- 

 punctata with hair-pencil overlying androconial scales in anal area on upper surface of hind 

 wing. Hindwing venation modified in <$ femandezi (Text-fig. 16) to support broad costal area. 

 Abdomen yellow. 



<J genitalia. Eighth abdominal tergite and sternite not strongly modified ; each with short 

 anterior apodemes. Saccus large. Vinculum greatly produced laterally and posteriorly in 

 femandezi and lurida; tegumen and posterior part of vinculum similarly produced in tripunctata 

 and quinquepunctata. Valves relatively small except in luridoides; with membranous costal 

 lobe in each species. Vesica of aedeagus scobinate in femandezi; scobinate and spinose in 

 other four species. 



$ genitalia [$ of lurida and quinquepunctata not known]. Seventh abdominal sternite 

 variously modified posteriorly; asymmetric in femandezi. Lamella postvaginalis with medial 

 sulcus in femandezi and luridoides; broadly concave in tripunctata. Ductus bursae short; 

 corpus bursae bearing two small, scobinate signa; appendix bursae large, its duct broad. 

 Anterior and posterior apophyses present; short. Paired scent-organs present. 



Some similarities in the coloration, wing shape and male genitalia suggest affinities
