NYMPHALIN.E. 43 



sect which is considered to be a dimorphic form of H. erato^ 

 as it usually occurs with it, and appears to be actually the 

 same species, called H. <&nY(Linn.), in which the red markings 

 are replaced by blue or green. 



Many of these species are very abundant, and have a very 

 wide range throughout Tropical America. 



We have figured a third species of the genus, H. sylvanus, 

 (Cram. ; pi. viii., fig. 3), which may serve to represent the black, 

 tawny, and yellow species. They are more restricted in their 

 range, J?. sylvanus being a native of Surinam. These tawny 

 species are often so closely mimicked by Ithomiince of the 

 genera Mechanitis, Fabr., and Mellncea^ Hiibn., as to be almost 

 undistinguishable in a cursory examination. 



SUB-FAMILY V. NYMPHALIN^E. 



Egg. Very variable in form. 



Larva. Spiny, or with fleshy prominences; feeds on low 

 plants, or shrubs. 



Pupa. Generally more or less angular, rather long. 



Imago. Generally of moderate size, rarely small ; antennae 

 usually with a distinct club ; wings ample, sometimes angu- 

 lated, or with a short tail ; the cells, at least of the hind-wings, 

 open, or closed by a rudimentary nervure ; sub-median nervure 

 of fore-wings generally forked at the base; inner margin of 

 hind-wings more or less concave. 



The Nymphalina are a very large group of Butterflies, in- 

 cluding, with the ApaturintZ) a quarter of the whole of the 

 Nymphalidcz, and divided into about 150 genera. Some 

 authors include the Morphines, with them, but these are now 

 usually treated as a distinct Sub-family. The Nymphalina 

 and Apaturincz may easily be distinguished from every other
