0. singularis Weym. (J above dark brown, in the end of the cell and behind it somewhat reddish, singularis. 

 Apical area black-brown. In the distal part of the cell an irregular, deep ochre-yellow spot. Beyond the cell 

 nuis an ochre-yellow transvei'se band, cni'ved somewhat basewards m the anterior part; it consists of 6 

 spots, of which the first three are more closely, the posterior ones loosely connected; at the upper median vem a 

 rounded wedge of the ground-colour projects from the cell into the band, making a deep excavation in it. 

 Xear the apex is placed a comparatively large, rounded, light ochre-yellow spot. Hmdwmg neax'ly oval, from 

 the base onwards brown ; beyond the cell this colour gradually changes into rust-red and finally into an unde- 

 cided deep ochre-yellow marginal baud ; before the subcostal, distally to and near the precostal cell, is placed 

 an anteriorly directed ochre-yellow hair-tuft, in the posterior part of the cell and between this and the sub- 

 median strong brown hair not arranged in pencils or tufts; and on a bare friction-patch at the hindmargm, 

 about in the middle of the submedian, a verj^ small hair-pencil. Under surface of the forewing brown, variously 

 clouded and shaded with lighter and darker. In and at the end of the cell confused black Imes, which enclose 

 and cover two band-like brown areas; between these some whitish dusting. In the lower radial cellule there is 

 a black eye-shaped spot. Distal margin grey-brown; near it run two black lines, both lost near the hinder 

 angle in the ground-colour, which is there grey-yellow. The apex is somewhat ochre-yellow, the hindmargmal 

 area smoke-bro^vn. On the submedian, near the base of the wing and covered by the anterior part of the hind- 

 wing, is placed a small, oblong ochreous scent-scale spot. Hindwing light brown, the proximal costal area 

 before the costal somewhat darker, with transverse white striation, the part of the wing behmd this area as far 

 as the median covered with irregular dark figures; distally hereto there is a large, roundish, eye-like spot 

 of various shades of brown, ringed with black-brown. In the posterior part of the wing there is a second 

 black eye-spot, placed in a light brown rmg, its inner disc dusted with yellowish and bearing a white streak; 

 the whole is ringed with black-brown and stands m a brown-violet area. The rest of the wing striated and 

 marbled with black-bro^\^l, the distal area more uniform brown, while the central part has a slight violet 

 sheen; the striation is sharpest in the hindmargmal area. Length of the forewing 44 mm. Guatemala, only 1

0. amphirhoe represents the Catoblepia group m central and southern Brazil. The species may be easily 

 known by its characteristic light grey marbled under surface, on which the apical eye-spots are displaced 

 far towards the distal margm. Two well differentiated local forms: amphirhoe Hbn., name-type probably amphirJwe. 

 from Rio de Janeiro, where accordmg to Bonninghatjsen (who erroneously called it xanthus) the larva, which is 

 of. a sea-green colour, lives on 23rickly palms. Both sexes essentially larger than the figured placita, the ochreous 

 band corresponduigly broader. Not very rare in Espiritu Santo. -^ placita Stick. (64 a) is always smaller, placUa. 

 the band of the forewuig always continuous, not broken up in the anterior intramedian area, as in amphirhoe. 

 Under surface much darker. Forewmg only with grey patches m the cell. Hindwing with more pronounced 

 black clusters of scales, which are condensed and developed into a kind of submarginal band. Apparently 

 common at Blumenau in Santa Catharma (8 ^^, 2 5$ in coll. Fruhstorfer); very rare in Rio Grande do Sul, 

 whence I only have 2 ^^ from Candelaria. According to Stichel an intermediate form seems to occur in 

 Sao Paulo, details of which are not yet known. There is still much to be desired as regards the exploration 

 of Brazil, which will provide one of the most remunerative tasks for the future.

Under surface of the hindwing with a curved row of 5 or 6 ocelli. <S above always with a hair-pencil in the 

 posterior part of the cell, a snialler one beliind the submedian and a brush-like tuft between this and the lower median. 



0. berecynthia somewhat resembles 0. xanthus L., except that the wings are more rounded and the 

 scent-hairs at the submedian are drawn out into a pencil instead of attached as a broad brush. Several geo- 

 graphical races, some of them very sharply differentiated, berecynthia Cr. Band of the forewing varying in lerecynihia. 

 breadth, in quite typical specimens only narrow. It runs obliquely, without touching the cell, from the costal 

 margin to the upper median vein, is then angularly curved posteriorly, gradually approaches the distal margin, 

 is narrowed and terminates in a sharp point not far from the anal angle. Its j)roximal boundary is fairly 

 smooth, only at the middle median vein somewhat notched, its distal margin less sharply defined, more or less 

 incised at the veins. Hindwing with complete but narrow, or partially indistmct, rust-red band at or near 

 the distal margin, in the former case as a rule only posteriorly touching the margin, anteriorly somewhat removed 

 from it. On the underside of the forewing the proximal of the submarginal lines only weakly curved, the distal 

 one placed rather near the margin. 9 paler, band of the forewing broader, its proximal boundary touching 

 the discocellulars, at the posterior angle of the cell, between the middle and upper median vems, projectmg 

 basewards in a tooth, the angulation less sharp, but quite appreciable at the distal boundary. Hmdwmg 

 at the distal margin with complete rust-red band, which in the anterior part is somewhat removed from the 

 margin. Under surface less bright, the lines near the distal margin of the forewing more strongly curved. Two 

 known aberrations in the form of the band : iatitaenia Fruhst. (64 a). Band of the forewing widened and strongly latitaenia. 

 angled, the yellowish distal margin of the hindwing dull, velata Stick. Band of the forewing narrowed and velafa.
