EUTERPE. 33 



Genus I. EUTERPE Swainson. 

 Sivainson, Zool. El. 2d ser. t. 74. (1831). 



Pieris, Heliconia, God?. 



Priamides, Archonias, Delias, Apostraphia, Hiibn. 



Head broad, hairy. 



Eyes oval, prominent. 



Labial Palpi distinctly triarticulate ; porrect, projecting beyond the head about half their length. 

 Basal joint stout, curved at the base, longer than either of the others ; second stout, shorter than 

 the first ; both clothed above with scales, below with long hairs ; third joint very slender, cylin- 

 drical, sometimes longer sometimes shorter than the second, clothed with short appressed 

 scales, and a few hairs at the base. 



Antennce long, terminating gradually in an elongate obovate club, sometimes slightly compressed. 

 Thorax stout, hairy. 



Anterior Wings triangular, or elongate, more rounded externally in the females than in the males. 

 First discoidal nervule united, for a considerable space beyond the cell, to the subcostal nervure. 

 Lower disco-cellular nervule about equal to the space between the second discoidal nervule 

 and the subcostal nervure. 



Posterior Wings obovate. The discoidal cell long. The discoidal nervure appearing to be a third 

 subcostal nervule. 



Legs rather stout. Claws deeply bifid. Paronychia broad, subtriangular, not quite so long as the 

 claws. Pulvillus jointed, as long as the claws. 

 Abdomen not extending beyond the posterior wings. 



Larva and Pupa unknown. 



This genus, consisting of but a small number of species, presents great diversity in form and colour. 



Some of the species, as Eut. Charops, offer a close resemblance to that group of the genus Pieris to which Pi. 

 Thisbe and Pi. Belladonna belong ; others, as Eut. Tereas, much resemble the females of many South American 

 Papiliones, as P. Polymetus and its allies. On the other hand, Eut. Bellona and Eut. Thcano very much resemble 

 some of the Heliconida;. Eut. Nimbice and its allies have a facies altogether peculiar. Eut. Notha has almost 

 precisely the colouring of Pieris Ilabra. 



There are three distinct types in the ncuration of the anterior wings. In Eut. Charops, Antodyca, and Swainsonii, 

 there are only three subcostal nervules ; the first thrown off considerably before the end of the cell, the second 

 considerably beyond it. This also is the case with Eut. Dysoni. In Eut. Notha we find four subcostal nervules ; 

 the first and second very little distant from one another, both emitted considerably before the end of the cell ; the third
