Genitalia : the general structure as in O. nisa, with which 0. adusta 

 occurs together, but different in the detail. Anal tergite broad, flat, slightly 

 curved downwards, the tip feebly sinuate. Lateral portion of the clasper feebly 

 chitinised, sole-shaped, the ventral portion incrassate, convex on the ventral 

 surface, concave inwardly, bearing a number of short conical teeth at the edge ; 

 from the dorsal edge of the clasper there projects a very long slender process, 

 lying above the anal tergite and being recurved at the apex, which is obtuse; a 

 second long slender process between clasper and the small anal sternite, this second 

 process also extending above the anal tergite, being sharply pointed ; in 0. nisa 

 the first process is only slightly cnrved and has a pointed tip, while the second 

 process is bent downwards and then upwards again, both processes being longer 

 than in the new species.

40. Othorene purpurascens intermedia subsp. nov. 



c? like that sex of O. p. purpurascens Schaus (1906) from the Guianas, but 

 the blackish antemedian and discal lines of the forewing more distinct, and the 

 clasper acuminate, not truncate or sinuate at apex. 



¥ similar to that sex of O. verana Schaus (1900) from Mexico and Guatemala, 

 but the ground-colour deeper and the lilacine shading along the lines more 

 pronounced.

41. Othorene pelias spec. nov. 



?. Head, upperside of thorax and base of abdomen ochraceons, the abdomen 

 gradually shading into pinkish buff behind ; underside of body dirty pinkish 

 buff, the legs washed with fawn-colour ; patagia edged with fuscous. No 

 projecting scent-organ at apex of abdomen. 



Upperside of wings clayish ochraceons. Forewing with an antemedian and 

 a discal line, both straight and blackish, the distal marginal and the basal areas 

 pink-buff ; a rouuded white discocellular spot at lower angle of cell ; the whole 

 wing, which is more elongate than in O. boisduvali Donm. (1859), minutely 



irrorated with fuscous ; hindmargin thinly edged with fuscous. Hindwing ovate, 



being distally evenly rounded, ochraceous, shading into clayish at distal margin ; 

 a diffuse blackish distal line, not quite extended to abdominal margin, curved, 

 situated at one-third the distance from lower angle of cell to outer margin ; 

 fringe white. 



Underside clayish pinkish buff, distal marginal area greyish ; the discal 

 line as above, but broader ; disc shaded with fuscous towards costal margin, 

 being more densely irrorated with fuscous speckles than the rest of the wings ;

42. Othorene tristygma amazonica subsp. nov. 



S. Similar to O. tristygina plateada Schaus (1900) from the Guianas ; the 

 blackish markings rather more pronounced, the forewing beneath bearing a large
