 western form of laqus\ from the quite similar salvini (141 k) the ^ differs by the light discal spot in the forewing 

 being small and often darkened, and by the entire absence of the light-blue cellular spot at the base of the fore- 

 wing above. — striata is a denomination byDnucE for $$ from Ecuador with a white oblique band, in which siriaUi. 

 the anal part of the hindwing above exhibits blue striate spots. The ,^ issaid to be beneath entirely like tyjiical 

 lagus, exhibiting above a somewhat larger discal spot and, in the inner-marginal area a blurred blue dusting. 



A. serica ll'^r. undoubti'dly ajijiroxiniatse the preceding, particularly velntina. The o has apparently arrim. 

 no white discal spot, but the metallic lustre extends almost over the whole forewing, so that only a broad costal 

 stripe and the apical part remain black. In the hindwing the reflection is chiefly confined to the part between 

 the lower cell-wall and the anal fold. Amazon. 



A. aniethystina Btlr. ,^ above lilack, with a violettish-blue reflection and a shortened white oblique iniiiihysii- 

 band; beneatli like Di/thid, but it has a more stretched costal margin of the hindwing than the latter and was, """ 



therefore, looked at as another species. The $ ist not described. From Santarem on the Lower Amazon.

 oblique spot of the forewing of the ^ which is sacciformly expanded in the $; the 3* has an almost entirely 

 light-blue, dark-veined hindwing, exhibiting beneath a yellow basal spot; the $ has beneath, at the hindwing, 

 triangular, white marginal spots. Upper Amazon and (somewhat less blue (J,^) also in Colombia and Bolivia. 



A. cyanea Btlr. t^ above black, with a blue reflection and an indistinct white dis(-al spot ; J with '■i/mird. 

 an orange oblique band and a blue-reflecting disc of the wings. Upper Amazon, Ecuador. In the collections 

 there is mostly the Central American form jansoni Btlr. (143 a). The ^ has a large white discal spot, the jan.wni. 

 a more flatly drawn out orange band. Both forms, moreover, occur beside each other, and the shape and position 

 of the oblic^ue band varies to such an extent that entirely alike specimens come only from the same flying- 

 place. Near Orosi (Costa Rica) the band is very broad, near Chontales (Nicaragua) uniformly band-shaped, 

 narrower and lighter yellow, near Burica in t'olombia behind the cell somewhat strangulated etc. Beneath 

 the (J shaded in a sepia-brown, except an oblique band in the forewing and white, towards the margin thickened

 f orewings and the hindwings have only at the border a brighter blue colouring ; but the under surface also exhibits 

 submarginal blurred spots. The $, in contrast with the preceding species, is more similar to the (J, but in front 

 of the distal margin it has white-blue wedge-shaped spots. Colombia. 



A. rhodinosa Stick. ,,$ of the shape of an epitus-^ but a little smaller; above black, the forewing with rluidinoga.

 a light-red band of a magnificent purple-violet reflection, being on the forewing nearly twice as broad as on 

 the hindwing. Under surface brown, the bands dull pink. Rio Songo, at an altitude of 750 m. Type a $ in 

 Fas.sl's collection. — I am of oj)inion that all the 3 species described last are forms of one species.

 band. Under surface brown with a submarginal row of white dots. The q varies at every habitat; sometimes 

 the bands are hemochrome and on both wings (typical specimens, if the bands are absent beneath), sometimes 

 the band of the forewing, or that of the hindwing appears also beneath; then again the band of the hindwing 

 may be absent altogether (hewitsoni Ky.) and the band of the forewnig may appear beneath instead; sometimes 

 agahi the band of the forewing is above broader and bent round like a hook, the colour more crimson than 

 hemochrome etc. As the $, Staudinger figures a butterfly with orange-yellow, distally black forewings and
