in the Basin of the Amazons. 249 



in the middle ; in the <? sharply cut off straight from the apex to 

 the anal angle. Palpi of ^ very hairy ; second joint long, obliquely 

 ascending ; third short, consisting of a double tuft, the base of which 

 is hidden among the projecting scales of the second ; tongue present ; 

 palpi of the ? shaped like the <? , but with appressed scales, not 

 hairy themselves, but concealed by the hairiness round them. 

 Antennae with two fine lateral bristles on each joint, densely and 

 shortly pubescent beneath throughout ; in the ^ thickened out and 

 flattened at the base. Head and face rough-haired ; patagia in the 

 <? remarkably long, upcurved and crested, reaching half-way down 

 the abdomen ; in the $ much less marked. Legs long and stout, 

 with long spurs ; all the femora hairy, especially in the <? . Neura- 

 tion : Fore wing, costal into the costa at quite three-quarters from 

 the base ; first subcostal branch at two-thirds of the cell, about the 

 middle of the wing at about one- sixth before the end of the cell two 

 branches rise from the same point, the upper one curving upwards, 

 the lower running close alongside of, and scarcely distinguishable 

 from, the subcostal itself to the end, then curving upwards, and 

 imiting with the upper ; from this point of conjunction the fifth sub- 

 costal branch runs straight to the hind margin some little way below 

 the apex, and the fourth curves into the apex itself, emitting at one- 

 third of its course the second, and the third just before its termina- 

 tion in the apex. Disco-cellular inwardly curved, scarcely angu- 

 lated, with a strong recurrent vein, the cell itself long, extending 

 nearly two-thirds of the wing ; upper radial from a little below the 

 top angle, lower from a little above the bottom angle of the cell ; first 

 median branch at two-thirds of the cell ; second and third from 

 the lower end ; interno-median fold strongly expressed, and curved 

 towards its base. Hind wing with the costal and subcostal 

 anastomosing for a very short distance near the base, the costal 

 thence running sinuously to the apex ; the subcostal with two long 

 branches; first median branch arising quite close to the base of 

 the median ; second and third short-stalked from the lower end of 

 the cell ; cell short and broad, with a well-marked free recurrent 

 vein from the radial. On the under side the base of the costa and 

 the basal portions of all the nervures beset with hairs, more 

 especially in the $ . 



31. Dysglyptogona dissimilis, n. s. 



Fore wing ochreous, dusted all over with black-tipped scales ; 

 with three transverse brown lines, which are all more undulating 

 in the 3' than in the 5 ; the first, near the base, forms a subcostal 

 angulation pointing outwards, and then runs sinuously to the
