apical portion ochreous yellow; the whole basal area of hind wing 



also ochreous yellow, leaving only a moderately broad dark outer 



border. Beneath, the yellow colour is of the same hue; but the 



brown portions are much lighter and of a silky glossiness. The 



outer border of the hind wing has a row of six or seven semicircular 



white spots. 



Both sexes, as above described, occurred at Ega, Upper Amazons, 



where neither A. Pythia, Hewits., nor A. Myrtis, Doubldy., was 



found. The two latter inhabit together the banks of the Tapajos 



and Lower Amazons ; and I think I am not wrong in considering 



them sexes of one species. 



Akicoris velutina. 



$ . Same form and size as A. Epitus $ (Cram. t. 270. f. C) ; differs 

 totally in colour. Dark brown, with a violaceous gloss, paler towards 

 the outer margins. Fore wing crossed by an oblique broadish orange- 

 yellow belt, extending from the costa to the outer margin near the 

 hind angle. 



Beneath brown, nervures paler ; outer border of hind wing very pale 

 brown, nearly white, except the brown nervures ; orange belt of fore 

 wing lighter in colour. 



S . The male is a fine insect, with elongated hind wings, like A. Epi- 

 tus (S {Cataleuca, Herr.-Schaff. Exot. Schmett. f. 28, 29). Above, 

 it is black, with the whole central area and hind limb of the fore wing, 

 and outer border of hind wing, rich glossy dark blue. Beneath, it is 

 dark brown, with much darker nervures and paler outer border; 

 a basal streak in the fore wing and costal spot beyond the end of the 

 cell are also light brown. 



I found the species only at St. Paulo, Upper Amazons. 



Akicoris disparilis. 



c?. 1" 4'". Similar in form to A. Lagus; above dark brown, with the 

 discal areas of the wings glossy violet-blue ; fore wing with a large 

 oval white spot in the centre. 



Beneath, difi'ers from all the allied species hitherto described, in the base 

 of the hind wing having a large irregular orange-coloured spot cover- 

 ing the basal portions of all the nervures. The fore wing is brown, 

 nervures concolorous, with two whitish streaks at the base, and the 

 large central white spot as above. The hind wing is violet-brown, 

 nervures darker, with a whitish streak in the cell, and elongated sub- 

 marginal whitish spots between the nervures. 



5 1" 3'". Similar in shape to A. Myrtis. Above dark brown, with the 

 basal third of fore wing (except the costa) and basal half of hind wing 

 orange. The orange-coloured portion of the hind wing is deeply 

 indented by the black border near the costa, and its hind margin is 

 festooned. The fore wing has in the middle of the black apical por- 

 tion a short white belt.
