180 ANTIRRHAEA. By G. Weymer. 



e 



In-own, and lias a slight violet reflection. The scent-organ of this species is elliiitical in form, with on 

 side pointed. This ]u-oximal point is placed in the angle of the submedian. The scent-organ is 13 mm. 

 lone and 6 mm. broad. The rather stiff hairs are placed close together at the margin and radiate in- 

 wards, so that their tips meet over tlie middle of the ellipse. Only the basal half of the anterior margin 

 of the ellipse is free from these hairs. The hairs themselves are 4 mm. long, light yellowish brown, 

 darker brown at the tip. Opposite to the scent-organ is placed on the upperside of the forewing a wedge- 

 shaped patch of flattened scales. From the Upper Amazon, Ecuador and Peru. Eare. 



oniala. A. ornata Btlr. Expanse 75 mm., thus somewhat larger than lielu. Violet-brown. Forewing with a 



row of 4 large, connected, round, black ocelli with rather large white pupils and ochre-coloured bordering. 

 Hindwing with a curved continuous row of 5 large oval blue ocelli wdiich have fine white pupils and are 

 placed in thick black rings. This row is likewise surrounded with ochre-yellow. The under surface is 

 ochre-yellow, finely striated with brown. The obtusely projecting angle of the hindwing is placed on the 

 upper median vein. Only the ? is known. Cayenne. Eare. 



b) Subcostal and upper radial of the hindwing in both sexes arise far apart and divaricate. Upper 

 discocellular half the length of the middle one. Inner margin of the forewing in the <^,^ only deviating 2 — 3 mm. 

 from the rectilinear, in the $? quite straight. Apex of the forewing rectangular. Hindwing running out to a 

 point on the upper median, obtusely angled on the middle a^ul lower median. 



iivryoti. A. geryon FJdr. (43 c). Expanse 85 mm. The distal margin of the forewing is almost straight, the 



greatest bend of the inner margin in the ^ lies sojinewhat before the middle and only attains "2 mm., in 

 the $ the inner margin of the forewing is straight. Ground-colour brown. Three large black eye-spots 

 measuring 5 — 6 mm., with white pupils 1 mm. large and brownish ochre-yellow bordering, are placed on 

 each wing, those of the hindwing in a curved row. In the $ the eye-spots measure 8 — 9 mm. The under 

 surface is brownish ochre-yellow, everywhere finely striated with brown, with brown median band on Ijoth 

 wings, two brown half-bands in the cell of the forewing, a similar half-band before the median band of the 

 hindwing and brown distal margin. In place of the eye-spots the forewing has three white dots and the 

 hindwing two white dots and a black one. There is further a black dot at the base of the hindwing. 

 The scent-organ is only 10 mm. long, is placed 4 mm. from the base and consists of a row of yellow- 

 brown hairs on the submedian, 3 mm. in length, with dark brown tips. It does not quite reach the middle 

 of the inner margin and is consequently concealed Iiy the hindwing even when the fore wing is set very 

 high. Opposite to the scent-organ is placed here also on the upperside of the forewing a pear-shaped 

 patch of flattened scales, which is 7 mm. long and 5 mm. broad, but may easily be overlooked. Moreover, 

 a smaU, bare, scaleless patch at the costal margin of the hindwing may be mentioned as the so-called 

 friction-patch. — The earlier stages of this species have been observed by F.vssl in Colombia : The egg is 

 hemispherical, white, not shiny; the base somewhat incised. Of the same size as that of Harpyia lunula. 

 The larva looks almost like that of Bomh. neustria, with similar variegated and well-defined markings, luit 

 with diverging dorsal lines. The very large head is ^yellowish green, the body posteriorly narrowed and 

 terminating in a long forked tail. The pupa is somewhat stouter, otherwise similar to a large Pyrain. 

 utakmta-iMx\Mi. Some are green and some brown, the variation being indeptuident of the sex. I'ood-plant 

 of the larva a species of palm. Colombian West Cordillera, or more exactly: Carmen 1800 m., valley of 

 the Eio Agna, 1800 m., from November to January, St. Antonio, 2000 m.. in April in dense, dark, primeval 

 forests at the passes. Huamboya in Ecuador (1200 — 2200 m.). 



ficnjonides. A. geryonides Weym. (43 c). Similar to the preceding species, but the ground-colour is dark olivo- 



brown, the distal half of the forewing and the liindwing especially dark. The eye-spots are larger, in 

 the (J measuring on the forewing 8 — 9 mm. in diameter, on the hindwing 5 — 6 mm. Their pupils are hke- 

 wise larger (2 — 2^4 min.) and bluish white. The red-yellow bordering of the ocelli in geryon is here 

 entirely absent. The under surface is likewise darker than in geryon. The white dots on the forewing are 

 somewhat larger and instead of the black dot between the middle and lower median vein of the hindwing 

 there is a small black ring with white pujiil. One of the principal differences is found in the scent-organ. 

 This is much larger than in geryon, covering a wedge-shaped, proximally pointed, distallj- rounded area 

 of 18 mm. in length, its greatest width being 6 mm. Hence even when the wing is not set very high the 

 distal part of the scent-organ lies free and only the proximal '/i are covered by the hindwing. The hairs 

 are arranged in two longitudinal rows and in the rounded distal part are placed close together, bending 

 towards one another with the tips touching. The patch of appressed scales placed opjjosite to the scent- 

 organ on the upperside of the forewing is of the same shape as in geryon and is distinctly visible. The $ 

 attains an expanse of up to 90 mm. The ocelli on the wings are even larger than in the (J, measuring 

 10 — 12 mm. on the forewing, 7 — 10 mm. on the hindwing. The bluish white pupils reach 2 — 3 mm. in 

 size. On the hindwing there is, moreover, a 4"' smaller ocellus, which occupies a different position in the 

 two $9 before me. In the Ecuador example it is placed between the loAver radial and the upper median 

 vein, but in the Colombian example near the costal margin. Moreover, the ground-colour in the latter is
