400 ME. H. W. BATES — CATALOGUE OP ERTCINIDJE. 



Exot. Butt. Nymph, f. 3) ; shape of wings the same. Above clear 

 dark brown without any admixture of rufous ; the whole central area 

 of both wings occupied by a large pale-ochreous patch, or broad belt, 

 extending obliquely from the upper radial nervure of the fore wing, 

 across the lower apical portion of the cell, to the abdominal edge of 

 the hind wing ; the ochreous area leaves a brown border rather nai*- 

 rower than that in N. Agle, and quite even on its edges, except within 

 the fore-wing cell. Down the centre of the fore-wing outer border 

 runs a pale-ochreous line, double as it approaches the hind angle ; on 

 the hind wing there is a chain of ochreous circles enclosing blackish 

 spots. Fringe dark brown. 



Beneath, the same as above, but paler, especially the brown borders. 



Abdomen of the male yellow, except at base, where it is brown like the 

 thorax ; in the female it is brown above. 



Hab. Ega and St. Paulo, Upper Amazons. 



Nymphidium fulminans, 



<?. 1" 9"'. Allied to IV. Lysimon, StoU (Suppl. Cram. pi. 39. f. 1); 

 differs in the wings being free from red streaks, and in the marginal 

 grey arched lines assuming very elongated acute-angular forms. 

 Above dark brown, centre of both wings ti'aversed by a very obliqvie 

 white belt, which begins with the fringe in the middle of the fore-wing 

 outer border, passes at a distance from the cell, and gradually widens 

 to the abdominal edge of hind wing. In the fore-wing cell, and 

 below the median nervure, are the usual grey lines forming parallelo- 

 gramical figures ; and there is a row of shorter marks between the cell 

 and the apex, and along the upper edge of the white belt. The marginal 

 arched lines do not differ on the fore wing from those of N. Lysimon; 

 on the hind wing they are so much elongated as to form acute-angu- 

 lar figures, the third from the anal angle being much longer than the 

 others. 



Beneath, the same, but paler, the brown margins mixed with grey. , 

 Fringe of hind wings above dark brown. Abdomen white in the 

 middle. 



5 . Same colours and markings as the c? , but wings elongated and 

 similar in shape to those of N. Mantus, Cram. (Pap. t. 47. f.F, G) ; 

 the white on hind wing narrow, similar to that of N. Mantus. 



Hah. Banks of the Tapajos and at Villa Nova (Villa Bella), Amazons. 



Nymphidium chimborazium. 



S- Closely allied to N. Lysimon, Stoll (Suppl. Cram. pi. 39. f. 1); 

 differs in the hind wing, only, having near the anal angle a short red 

 stripe. Above dark brown ; fore wing with a triangular white spot, 

 its apex on the middle of the terminal branch of the median nervure; 

 hind wing with a broad white belt across the disk. The usual pale 

 figures in the cell of the fore wing are of broadish oblong shape ; the 

 marginal semicircles on both wings ai"e similar to those of JV. Lysi-
