0. singularis Weym. ^ above dark brown, in the end of the cell and behmd it somewhat reddish, sinyularis. 

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

 runs an ochre-yellow transverse band, curved somewhat basewards in the anterior part ; it consists of G 

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

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

 Near the apex is placed a comparatively large, rounded, light ochre-yellow spot. Hindwing nearly oval, from 

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

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

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

 median strong Ijrown hair not arranged in pencils or tufts, and on a bare friction-patch at the hindinargin, 

 about in the middle of the submedian, a ver_v small hair-]3encil. Under surface of the forewing brown,, variously 

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

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

 a black eye-shaj^ed s23ot. Distal margin grey-brown; near it run two black lines, both lost near the hinder 

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

 area smoke-brown. 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 behind this area as far 

 as the median covered with irregular dark figiu'es; 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 ring, its inirer disc dusted with yellowish and bearing a white streak; 

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

 marbled with black-brown, the distal area more uniform brown. M'hile the central part has a slight violet 

 sheen; the striation is shariiest in the hindmarginal area. Length of the forewing 44 mm. (Guatemala, only I

0. amphirhoii represents the Catohlcpia grouj) in central and southern Brazil. The species may be easily 

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

 far towards the distal margin. Two well differentiated local forms: aniphirhoe Hbii.. name-t\^5e probably amphirhoi. 

 from Rio de Janeiro, where accordmg to BoxNixciiL\u.SEN (who erroneously called it xunthus) the larva, which is 

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

 band correspondingly bi'oader. Not very rare in Espiritu Santo. — ^ placita SticJi. (64 a) is always smaller, ylacila. 

 the band, of the forewing always continuous, not broken up in the anterior intramedian area, as in (tmphirhuv. 

 Under surface much darker. Forewing only with grey patches in the cell. Hindwing with more pronounced 

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

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

 whence I only have 2 ,^3* from Candelaria. According to Stiohel an intermediate form seems to occur in 

 Sao Paulo, details of which are not yet known. There is still nnich to be desired as regards the ex])loration 

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

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

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

 breadth, in quite tyi^ical 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 proximal boundary is fairljr 

 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 indistuact, 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. 5 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 veins, projecting 

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

 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: latitaenia Fruhsf. (04 a). Band of the forewing widened and strongly latUaenia.
