50 Mr. A. G. Butler on a new Genus of Diurnal Lepidoptera, 



This genus, although it has somewhat of the appearance of 

 Mycalesis (fig. 3), is totally distinct from it, and is much more 

 nearly allied to Debts (figs. 2, 2^, 2^) ; in fact the neuration is 

 almost identical with that of the latter genus; but the great 

 size of the typical species, its clubless antennae, naked eyes, 

 and erect palpi at once distinguish it. I therefore propose the 

 name Anadebis. 



In some respects this form seems to be nearly allied to Ame- 

 chania of Hewitson, which should, I think, be placed between it 

 and the genus Orinoma (figs. 4, 4^) of Doubleday, and not, as in 

 the ' Exotic Butterflies,^ in the family Eurytelidse. 



Anadebis, gen. nov. PI. II. figs. 1, 1% 1^. 



Magnitudine formaque Tisiphones, Hiibner. Alse anticse magnse, 

 subtriangulares ; costa arcuata ; apice convexo ; margine postico sub- 

 directo ; angulo anali convexo ; margine interiore subdirecto. 



Alse posticae late ovatse ; costa subdirecta ; apice convexo ; angulo 

 anali subconvexo ; margine postico sinuato : venis apud basim vix 

 tumidis, velut in Debe positis. 



Corpus thorace brevi, cirrato ; capite cirrato ; antennis tenuibus, 

 apicibus vix clavatis, medium alarum anticarum attingentibus ; palpis 

 elongatis, erectis ; oculis exstantibus nudis. 



Fore wings large, subtriangular ; costa strongly arched ; apical 

 angle rounded, outer margin nearly straight ; anal angle rounded; 

 inner margin nearly straight. 



Hind wings broadly ovate ; costa nearly straight ; apical angle 

 rounded; outer margin slightly scalloped; anal angle slightly 

 rounded. 



Nervures at base of wings scarcely swollen. 



Fore wings. Costal nervure extending some distance beyond 

 the cell; first and second subcostal nervures emitted just before 

 the end of the cell; the first disco-cellular nervule very small and 

 oblique, the second rather longer, the third very long and slightly 

 waved ; the first branch of the first discoidal nervure emitted, 

 as in Mycalesis (fig. 3% 3^), before the middle of the vein, the 

 second branch reaching the apex, the third emitted at one-third 

 of its length from the apex; the second and third discoidal 

 nervures are emitted near the apex of the cell ; the first median 

 branch arises just beyond the middle of the median nervure, the 

 second at about one-sixth of its length from the base ; the third 

 is shghtly curved outwardly, and terminates the cell. 



Hind wings. Precostal nervure curved, the tip directed in- 

 wards ; costal nervure extending to beyond the middle of the 

 costa; first branch of subcostal arising at some distance from 

 the base, its extremity extending to the apex; the upper and 

 lower disco 'CeUular nervules curved, oblique, of about equal
