Of typical siiff'erta a c? from Iliiaiicabamba ami two 6S from Ciislii, I'ltii, 

 have been received, along with 9 Si anil 1 ? from (Jiishi of the more ordinary 

 form, which may be known as ab. distincta.

The form described by me as an aberration of amcthi/stata Wlk. must be 

 separated as a distinct species. As often happens, the specimen which served as 

 type is somewhat different from the ordinary form, of which I have now seen 

 o or (j more iS and 1 ?. In these H the enter line is not marked by white 

 vein-dashes, but either by a fine darker line with pale edge, or by a pale line 

 alone ; there is no visible trace of an inner line, but the base of inner margin is 

 pale green ; the black triangle at ajie.x is generally represented by the usual short 

 blackish subapical streak followed by a white dot on costa. The ? is a very 

 beautiful insect, the dull salmon-colour of the S being deepened into amethyst, 

 with the submarginal baud standing out across the wing clear pale green ; the 

 costal area is sliglitly paler, and tlu're is no trace of any black snba])ical mark ; 

 the outer margin and fi'iiige of liiadwing are flushed with amethyst, and the same 

 tint takes the place of the olive shading of the underside of the S- As in the 

 other species of the genus, the apex of forewing in the ? is prodnced, and the 

 outer margin incurved below it and gibbons in middle. 



All the examples are from Oconeqne, Carabaya, Peru, taken in Jnly (dry 

 season) 191)4, by Ockenden.

The specimen from which I describrd fortirt is a very dark example, with the 

 cell-spot of forewing, the upperside of hindwiug, and the underside of both wings 

 all nearly black ; the examjjle described as aiinidifera ¥ represents the more 

 comiuon and paler form, of which 1 have seen a pair from Agnalani ; in this form 

 the red tints predominate over the olive ; but in ((iiiiiili/rra ty[>e <S the red tints 

 are absent and the whole forewing is olive-green ; of these I have seen 3 Jc? only 

 from R. Hnacamayo, agreeing with the original S in coloration. Their identity 

 with Crocallis goleta Dogn., which I have only recently ob.served, is umpiestionable.

<5 . Foi-t'iriii(/ : dull fnlvous, almost hidden by an olive-fuscons sntlusion and 

 numerous dark transverse striae ; the lines chocolate-brown ; inner line at two- 

 tif'ths, visible only as an outwardly obli(pie costal streak ; outer line at four-fifths, 

 oblique outward to vein 7, there acutely angled, and inwardly oblique, slightly 

 curved to three-fifths of inner margin, edged externally by a thin ]ialer line; 

 cell-spot black, followed by a diffuse brown median shade ; attached to the inner 

 side of outer line between veins '^ and 4 is a large pear-shaped yellowish ochreous
