greenish, distally with violet-bhie reflection. This reaches in the cell about to its middle, below it to two-thirds 

 of the Mndmargin and is gradually lost in the ground-colour. In the costal area of the hmdwmg and on 

 almost the whole of the forewing the dark markmgs of the mider surface shoAV through slightly. Under surface 

 rather coarsely and profusely marbled, forewuig with two eye-spots. The $ is larger, the bluish colour below 

 the cell of the forewing weaker, the light band beyond the cell broader, the undulate band between the strongly 

 dentate Imes which show tlu'ough from beneath near the distal margin standing out more distinctly. The blue 

 on the hmdwing further extended, deeper in tone, with less greenish reflection. In the Amazon region extending 

 towards the west and north-AVest (Peru, Colombia), tliis race becomes transitional towards C.teucer suzanna, 

 being more brightly coloured, with a somewhat darker costal area on the forewing and more copious blue 

 dusting at the liindmargin, while the hindwing shows a more extended blue basal area. Guiana, northern 

 nubilus. Brazil, western Peru. — ■ nubilus Fruhst. {63 c). Bgjid distally to the cell of the forewing completely suppressed, 

 ground-colour in the cell especialty dark, a dull blue gloss spreads almost uniform^ over the whole proximal 

 obidonus. half of both Avings. British Guiana. — • obidonus Fruhst. Paler than the type-form.. The blue basal area of the 

 liindAvmg extended to the end of the cell, hence the distal and anal area more narrowly black-broAvn. Under 

 surface more marbled AA'ith white, m the cell of the forewing with brighter white bands. In the hindwing 

 the posterior ej^e-spot Avith smaller black pupil and broader yellow ring, in the cell the white elongate patches 

 standing out very brightly on a brown ground, the oval ring-spot before the middle discocellular on the other 

 japetus. hand more weakly coloured. Amazons (Obidos). — japetus Stick., from Paraguay, has broader Avings than 

 typical teucer; the spindle-shaped broAvn costal area AA'idened so as only to leave free the extreme distal angle of 

 the cell, which assumes the colour of the adjoinmg transverse band. This is almost ochre-yellow, posteriorly 

 somewhat paler. The triangular grey area behmd the cell, wMch posteriorly to and in continuation of the 

 transverse band is bounded by the dark broAvn distal area and anteriorly reaches to the origin of the middle 

 median vem, is shot with bluish thi'oughout, and a narroAv posterior stripe in the cell is also slightlj; tinged 

 Avith blue; in an oblique light this dustuig shows a beautiful sky-blue sheen. The light transverse band betAveen 

 the curved lines Avhich shoAV tlu'ough from beneath near the distal margm more distmct and proximally in parti- 

 cular standing out very sharply against the dark area. Blue basal area of the hindwing extended to the end of 

 the cell and nearly to the hinder angle, in an oblic^vie light Avitli brilliant violet-blue reflection. The strongly 

 undulate distal margin profusely dusted Avith whitish, particularly at the incisions. Under surface in general 

 with somewhat lighter ground-colour, the distal half of the liindwing in particular with strong AA^hitish admixture. 

 In the forewing only one eye-spot, near the apex. $ larger; the bluish tinge on the foreAving spreads over almost 

 the entire cell, but is somcAvhat less pronounced. The band behind the cell broader, anteriorly, in the radial 

 interspaces, with pointed, wedge-shaped teeth proximally. The band near the distal margin dirty oclu-e-yeUoAV, 

 more distinctly detined, distally in particular bordered by a stripe more strongly dusted AA-ith black-broAA'n. 

 HindAving with the basal area considerably widened, in an oblique light with brilliant violet-blue and greenish 

 reflections. It extends about 6 — 7 mm. beyond the end of the cell, nearly reacliing the anal angle. Under sur- 

 face someAvhat less brightly and more coarsely marked. Thorax and abdomen strongly dusted with grey-blue. 

 phoroneiis. — -phoroncus Fruhst. This local race, with the upper surface strongly darkened, forms a transition from tliu 

 light forms of the LoAver Amazon region to the dark siizcinnaDeyr. from Colombia. The light yelloAAish area 

 Avliich in teucer and obidonus Fruhst. spreads over a third of the forewing is reduced to a rather sharply defined, 

 narrow dark yellow band, Avhicli in the (^ still covers the extreme apex of the cell on the forewing. In the $ 

 this band is even more narroAved and runs beyond the cell, gradually becoming darker and terminating before 

 the 3rd median vem. The cell of the cJcJ is darkened with the exception of the apical and lower parts, that 

 of the 5$ entirely darkened, and shot with deep blue. The hinclAving except the black distal margin with as 

 dark blue gloss as in euphorbus Fldr. The large ocelli on the miderside of the liindwmg characterized by having 

 a brown border, which is much more extended than in teucer and obidonus. Jaupes. 



C. illioneus occurs together AVith teucer, but its range extends somewhat further south on the Atlantic 

 coast and it is still met Avith at Eio de Janeiro, Avhere according to Bonnikghausen it occurs on the north 

 side of the bay at Piedade. Unlike teucer, its early stages are well known. Larva on bananas. Northwards 

 illioneus extends as far as Panama. Such localities as Guatemala and Mexico are no doubt due to errors in 

 determination, it havmg been confused with memnon, wliich is everywhere common in those countries. — 

 oheron. oberon Btlr. cJ, very dull-coloured, the blue of the forewing in the costal and posterior part of the cell very 

 fault, the posterior angle of the latter entirely free, the reflection strong but darker. Transverse bands dull, 

 sometimes even mdistinct. The proximal one as a rule only someAvhat more distinct anteriorly, from the radials 

 ouAvards obsolescent, the distal suuious, the costal curves more, the anal less strongly diffused on either side of 

 the veins in such a Avay that the rays are as a rule united anteriorly with the srhaller curves of the proximal 

 band, forming elongate ring-spots in Avhich are enclosed oval spots of the dark broAvn ground-colour, some- 

 times proximally truncate. This formation, although it occurs more rarely also in single individuals of other 

 subspecies (particularly in G. i. polyxemis), is in general very characteristic of oberon. $ paler, with the same 

 peculiarities, the transverse bands of the forewing somewhat lighter, the markings of the mider surface shoAv-
