similar in size and range of coloration to Mesene, but diifering 

 in the mueli more bulky thorax and abdomen, and especially in 

 the abbreviated and thickly clubbed antennae. The wing neura- 

 tion is the same as that of Mesene and the allied genera ; the 

 palpi are very short, not passing the lower edge of the frontal 

 pad ; and the hind wings are hroadly rounded, with the outer 

 margin on about the same level as the anal angle. The an- 

 tennsB scarcely reach to half the length of the costa of the fore 

 wing ; their shafts are brown, spotted obscurely with ashy or 

 lighter brown. Eyes naked. The male fore legs are very short, 

 the other legs are moderately elongate and clothed with short 

 scales. 



The species are very rare, 



Pachythone erebia. 



c? . 1" 2'". Fore-wing costa incurved in the middle, sharply arched before 

 the apex. Dark sooty brown, fringe white : above immaculate. Be- 

 neath paler brown, with a submarginal row of obscure darker spots 

 and paler lunules on the hind wing. 



Head, body, and legs sooty brown ; tarsi white, tipped with black. 

 Antennae dark brown spotted with ashy ; club thick, oval, black. 



Hab. Ega. Resembles in colours Mesene fuliginea. 



Pachythone lateritia. 



J & $ . 1" 3'". Fore-wing costa very shghtly incurved in the middle 

 and gently^ arched before the apex. Above clear light brick-red, 

 spotted with black, the outer margins also edged with black. The 

 spots are elongated and arranged in two rows near the base, and on 

 the outer hall' of both wings form three curved macular belts cross- 

 ing the wings ; one of them, passing a little beyond the cell, is more 

 flexuous. Fringe black, costal border of fore wings brownish. 



Beneath, the same, but paler, and the costa and apex of fore wing 

 broadly bordered with brown. 



Body above reddish, beneath whitish. Legs pallid. The antennae in a 

 well-preserved female example are dark bi-own ringed with ashy, and 

 the club blackish ; in a worn male the organs are pale rufous, ob- 

 scurely ringed. 



Hab. Tapajos and Ega. 



Pachythone distigma. 



c?. 1" 3'". Fore wing elongate triangular, costa slightly incurved in 

 the middle. Above dark brown, including the fringe ; the hind wing 

 with a transverse oblong tawny-orange spot between the cell and 

 outer margin, and not reaching the abdominal edge. Fringe dark 

 brown. 



Beneatli paler ; in both wings a submarginal row of regular rounded
