OF THE AMAZON VALLEY. 563 



black ; a submarginal row of whitish spots, interrupted in the middle. Beneath, the 

 same, except that the costal nervure is also black, and the submarginal spots are larger 

 and of a clearer white, there being two between each nervure, except near the apex, 

 where there is only one, instead of two. 



Body brown ; antennae yellow, except the extreme base, which is black ; forehead and 

 two spots on the crown white ; mesothorax with four large rounded orange-tawny spots, 

 namely, two wide apart on the shoulders and two near together in the middle. 



This fine large species is deceptively like Stalachtis Calliope. It appears to be very 

 rare. I met with only one individual; at St. Paulo. Stalachtis Calliope is a very 

 abundant species.

 Colcenis Mereaui, Hiibn. Zutrage, f. 201, 202. 



The sexes differ considerably in the colours and design of their wings. The c^ is dark 

 orange-tawny ; the apical half of the fore wing is black, sometimes crossed by a short 

 orange-tawny belt ; the hind wing has a broad and rather well-defined black border. 

 The ? is paler in hue, and has two or three large ochreous spots in the middle of the 

 fore wing ; the apical half is black, sometimes with an ochreous spot on the costa, half- 

 way between the cell and the apex ; the black border of the hind wing is ill defined, 

 shading off gradually into the ground-colour of the wing. 



I met with this species on the Tapajos and Upper Amazons. It is found within the 

 forest, flying about the tops of low trees in sunny openings. It has no near ally in the 

 Amazon region, to my knowledge.

A very common species throughout the country. It flies in open sunny places on the 

 skirts of the forest, or in semicultivated grounds. The caterpillar resembles in all 

 essential points those of Hellconius Urate and the species of Argynnis. Each abdominal 

 segment is furnished with a row of rather long hispid spines ; the head has two similar 

 spines, longer than those of the abdomen ; the colour is pale red ; the spines black. The 

 chrysalis is angular, and spinose on its dorsal sm'face. The pupa state lasts eight days.

Eueides Thales, Hewitson, Journal of Entomology, i. pi. 10. f. 3 (var.). 



A common and generally-distributed species in equatorial America. It closely resem- 

 bles Heliconius Vesta, in company with which it is frequently found. 



7. Etjeides Eanes, Hewitson. 



Eueides Eanes, Hewits. Journ. of Entom. i. pi. 10. f. 1. 



This species also closely resembles Heliconius Vesta. It is found only on the Upper 

 Amazons, at St. Paulo, flying over bushes on the skirts of the forest.
