brown and grey speckled butterfly intermediate in 

 size between the "Blues" and Pyrameis. Its name is 

 Pararge egeria. Studying its structure we find that its 

 wing-neuration (fig. 90) agrees with that of Pyrameis 

 in the presence of five radial branches, and in the 

 absence of the small anal nervure ; but differs in the 

 presence of discocellulars, closing the cell, and in a 

 marked thickening of the main nervures at the base 

 of the wing. Like Pyrameis, 

 it is a " brush-footed" butter- 

 fly, walking on four legs only. 

 Its caterpillar is elongate, 

 though hairy not spiny ; its 

 pupa rotund and without 

 tubercles. It is usually refer- 

 red to a family distinct from 

 the Nymphalidas — the Satyridse. 

 Yet it agrees with the Nym- 

 phalidje in the striking character 

 of the aborted front legs and 

 does not differ markedly in its 

 type of wing-neuration; 

 evidently it is nearer to the 

 Nymphalidge than to the 

 Lyc£enid«. Some naturalists 

 would express this fact by 

 classing Pararge and its allies 

 as a sub-family of Nymphalidae, 

 calling them Satyrinx.^ Others, 

 allowing them family rank, would group them together 

 with the Nymphalidoe and other allied families into a 

 super-family, to which they might give the name of 

 Nymphalides. 



^ Throughout the animal kingdom family names end in ii/se, 

 sub-family in iwae, both being compounded from the name of the 

 typical genus as Lijcana, Lycienida.
