of the band 2 small white dots. Beneath the median area forms a broad band, brown, distally tinged 

 with lighter and darker ochreous, bordered en each side by a whitish stripe and distally in addition bounded 

 by a twice broken black-brown line. Succeedmg this the distal area is in its anterior, triangular part brown 

 striated with white, posteriorly and distally with two black, yellow-ringed eye-spots, placed one behind the 

 other, before these another black spot and two blind eye-spots near the apex. The area distally to the cell 

 copiously dark-striated, bounded by a dark undulate line edged with ochre-yellow or whitish. Distal area 

 rust-brown, likewise with dark, whitish-bordered line near the whig -margin. Hindwing with pale brown 

 hindmargmal area, a bare friction-patch with pencil-like hairing between submedian and hindmarginal vein 

 and a large mealy scent-scale spot m the region of the hinder angle. Ground-colour otherwise dark brown, 

 in the middle of the wing tmged with reddish, distal margin narrowly bordered with rust-brown. Under surface 

 in the basal and distal areas brown, profusely striated with black or black-brown. Median area broadly band-like, 

 dark brown with white bordering. The area beliind the ej^e-spots more or less striated with whitish. In the 

 anterior part of the median area is also placed a large dark brown eye-spot with yellowish ring and white 

 pupil. In the distal marginal area there is an vmdulate line bordered with light brown. 5 unknown. Bolivia. 



b) with brush-like hair- tuft close to the submedian of the hindwing. 



E. aesacus comes from Central America, extending from Mexico to Colombia and dividing into two 

 local forms: aesacus i7.-(Sc^a//. (64 b) is the smaller subspecies. (J: Forewing near the distal margin with faint aesacus. 

 ochre-yellow transverse band, which is distmctly forked anteriorly as in the preceding species and almost to the 

 same extent as in the $ of the present subspecies. The median area of indigo-blue tone, anteriorly only 

 distinct as far as the upper median and the end of the cell, distally as far as the transverse band, which is 

 itself faintly tinged with blue. Hand wing behind the apex near the distal margin with the blue tinge only in 

 patches, in the middle of the wing becoming more or less of a band posteriorly. The distal margin is very 

 nearly roimd, only at the middle median vein with an obtuse, scarcely appreciable angle. $ paler, the pale 

 blue tinge on the forewmg of a light violet tone, vaguely defined, leaving the end of the cell free, but rather 

 distinctly developed mto a broad band from the costal margin obliquely to the hindmargin. Hindwing at 

 the base without blue dusting; indistinct traces of this first appear near the middle of the cell, whence 

 it gradually increases in sharpness and forms m the middle of the wing a spot extending to just beyond 

 the end of the cell and there somewhat more sharply defined. Mexico (from whence the type came), Guatemala 

 and Xicaragua. Everwhere rare. From Honduras in coll. Frfhstorfer. — buboculus Btlr., described from buboculus. 

 Costa Rica, extends southwards to Colombia. Larger than aesacus, darker coloured and beneath more sharply 

 marked. According to Fassl is one of the highest flying Brassolids in the Colombian Andes. — juruana subsp. juruana. 

 nov. has rounder wings, is above more blue mstead of violet and the yellow submarginal band of the forewing 

 is narrow^er. From the Rio Jurua, a southern tributary of the Amazon (type in coll. Staudinger). 



E. gerhardi Weeks is a species of which only a few examples have yet been found and was placed gerhardi. 

 by its author in the genus Caligo. Upper surface brown, tinged with dark blue except at the costal margin. 

 Under surface reddish ochreous. Costal margin of the hindwing somewhat flattened, at the apex rounded and 

 passing gradually into the strongly undulate distal margin, the latter slightly angled at the middle median 

 vein, anal angle fully rounded, basal area strongly hairy to the middle of the cell. Upper surface brown, a broad, 

 ill-defined stripe, about from the middle of the cell nearly to the distal margin, suffused with blue; the hind- 

 marginal area vaguely yellow-grey, posteriorly with grey-blue gloss, with a large, oval mealy whitish-yellow 

 scent-spot, proximally adjoining the hindmarginal vein. Under surface reddish oclu-e-yellow, basal area and 

 the zone behind the cell as far as the distal margin rather uniformly and finely striated with blackish. A trans- 

 vense band in the middle of the wing vaguely red-brown, distally not sharply defined, proximally distinctly 

 bounded by a silver-white transverse stripe which forms a continuation of the white band on the forewing. 

 The stripe fades out posteriorly at a raised spot which indicates the scent-scale spot of the upper surface. 

 In the cell, touching the stripe, there is an irregular zigzag marking, two pointed oval figures follow at 

 the end of the cell, and in its anterior angle is placed a white spot. $ still unknown. Bolivia, Ecuador (Sarayacu). 

 — • In pusillus Stick, the rj is smaller than in the preceding form; the violet-blue dusting lighter and somewhat pusiUus. 

 more distinct, broader on both wings, especially posteriorly and towards the apex of the forewing and the distal 

 margin of the hindwing. The latter more obtusely angled at the middle median vein, apex of the forewing 

 likewise somewhat more obtuse and less produced. Paraguay, Rio Grande do Sul. Mabilde bred pusillus 

 on one occasion. The $ laid in captivity on the 1st of November 10 eggs, from which after 8 days emerged 

 larvae of dark green colour; these moulted within 15 days, repeating this four or five times down to the 14th 

 January and for the last time on the 4th March. The pupal stage, however, lasts only 13 days, while 

 the larvae feed sometimes for 2 months, occasionally even for 4. The pupa somewhat resembles that of Caligo 

 mariia, but is more delicate, more compressed, of lighter colour, with a slight rosy gloss and separated light 

 patches. The butterfly flies in Rio Grande throughout the summer and autumn, inhabits the forests and 

 bamboo district, but is nowhere common.
