178 PIEEELLA. By G. WEYirER. 



placed next tu the bayo on the hindwing is rather indistinct. At the apex of the liindwing two romid 

 black spots, of which the anterior one has a white pupil towards one side, but the other is bhnd and 

 smaller. On the lighter under surface with fine brown striae the transverse lines are more distinct than 

 above, between the 2"'' and 3''^ on the forewing there is a fourth, which only extends to the upper 

 median vein. The ocellus of the hindwing is smaller, the black spot is absent. In the marginal area there 

 are 4 white dots on each wing. In the (^^ above seen in a certain light there is a light green reflection, 

 heracles. in tlie $ the marginal area is darker. Nicaragua, Costa Eica, Panama, Colombia, Guiana. — heracles Bdv. 

 (= rubecula Godm. & Salo.). A northern form with the same green reflection on the forewing in the ^, 

 but distinguished liy the reddish brown colour of the costal area on the hindwing above. This colour is 

 gradually merged at its edges into the dark brown ground-colour. The dark brown distal margin is 

 .5 — 6 mm. in breadth. The 2 black ocelli at the apex are ])hic<id at the boundary of tlie two colours and 

 lesbia. have often white pupils. From Mexico and Guatemala. — lesbia >Slyr. (43 a) I regard as a southern form 

 of luna, which approaches heracles. The median patch of the hindwing, however, is more reddish yellow 

 and more distal than the reddish brown patch of heracles. The dark brown distal margin is only 1 — IJi ™™- 

 in breadth and rather sharply defined. Of the 2 round black spots at the apex only the upper one has a 

 white pupil. Under surface as in huia and heracles. From Bucay in Ecuador and the Rio San -Juan in 

 West Colombia. 



rhea. P. rhea F. (43 a) approaches luna, having the same markings and the green refii'ction on the fore- 



wing, but the ground-colour is more yellowish brown, the hindwing somewhat darker than the forewing. 

 The former with a row of 5 black ocelli with white pupils, of which the 3 posterior ones are somewhat 

 smaller and the last is often very indistinct. On the under surface the brown lines are as in luna, but 

 the eye-spot at the apex of the liindwing is absent, on the other hand the row of dots (2 or 3 on the 

 forewing, 5 on the liindwing) is very distinct. From the Amazon; Rio de Janeiro. 



lamia. P. lamia Sulz. (= dyndimene Cr.) (43 a) is similar to rltea, the green reflection is likewise present 



in the ,^ on the forewing, but the liindwing has a steel-blue gloss, which is absent in rhea; the 5 black 

 eye-spots are all equally large and distinct, the white dots in them somewhat stronger. From Cayenne, 

 Surinam, Colombia. 



chalybaea. P. chalybaea Godm. was described as similar to lamia, but differing from it in that more than the 



basal half of the hindwing in both sexes is shot with steel-blue, the black rings round the white dots are 

 almost or entirely absent, the distal margin of the hindwing is very broadly darkened and the 2 central 

 lines are indistinct. From Chapada in Brazil. 



hijccla. P. hyceta Heir. (43 b). A beautiful species. The forewing is similar to that of the preceding 



species in colouring and markings, and also shows the green reflection on the ^J,^ in certain lights, but the 

 hindwing has reddish ochre-yellow ground-colour, only the base and costal margin agreeing with the fore- 

 wing. Of the 3 brown lines on both wings the middle one on the hindwing forms rouglily the indistinct 

 boundary of the two colours. Four, occasionally five, round black spots form a submarginal row, only the 

 anterior one has a white pupil, the 2"'^ is the largest. Between the 2"*^ and 3'''' is sometimes inserted a 

 fifth spot (as in the ^-example figured). At the distal margin of the hindwing are placed brown triangles. 

 On the under surface the ground-colour of both wings is yellowish grey, finely mottled with brown, the 

 straight brown lines stand out distinctly, the black spots are much smaller than above, and have here in 

 the 9$ white pupils, sometimes also in the (^(J. From the Upper Amazon, Cuzco in Peru (3000 in.), 



latdiia. Bolivia. — latona Fldr. is a form of hyceta, in which the central area of the liindwing is deep red- 

 .yellow and the distal margin blackish, moreover the two posterior black spots are larger and have no 

 white pupils. In the $ all the spots are larger and provided with white pupils. The under surface is as 

 in hyceta, but the anterior spots of the hindwing are smaller and with white centres. From Bogota 



eenjce. (Colombia). — ceryce Hew. (43 b), likewise a form of hyceta, in which, however, the central area of tlu^ 

 liindwing is red-brown and the Idack-brown distal margin has a breadth of 8 — 10 mm. In the latter are 

 placed in the i^(^ 4, in the $$ 5 black ocelli with white pupils. Moreover, the ground-colour of the fore- 

 wing is darker than in hyceta, hence the dark brown lines stand out less, as is also the case on tin* hind- 

 wing. The o has the same green reflection in the middle of the forewing as hyceta, whilst the $ bears 

 3 white dots before the apex of this wing. The under surface is grey-brown, darker in the marginal area, 

 with 3 fairly straight brown lines on both wings, 4 or 5 white dots instead of the eye-spots on the hind- 

 wing and some similar dots at the apex of the forewing. A black dot at the base of the forewing and 

 2 or 3 at that of the hindwing. From Pintuc in Ecuador (800 — 1000 m.), Chanchamayo in Peru, and Bolivia. 



c) With three almost straight, parallel dark lines only on the underside of the hindwing. On the 

 upperside a blue spot on each wing. 



horloHu. P. hortona Hew. (43 b). Ground-colour dark black-blue. The blue spot of the forewing is elongate, 



varying in size, 3—4 mm. broad and 6—12 mm. long, and is placed on the discocellular. That of the
