HIPPARCIIIA. 231 



rant, being large tawny Butterflies, more resembling true 

 Satyrus. In South America the section is very poorly repre- 

 sented, Argyrophorus argenteus (Blanchard), from Chili, being 

 the only remarkable species belonging to it. 



GENUS HIPPARCHIA. 



Hipparchia, Fabr. in Illiger, Mag. Insekt, vi., p. 281 (1807); 

 Steph., 111. Brit. Ent. Haust, i., p. 53 (1827). 



Satyrus, pt. Latr., Enc. Meth., ix., pp. n, 460 (1819-1823); 

 Westwood, Gen. Diurn. Lepid., p. 388 (1851); Schatz 

 and Rober, Exot. Schmett., ii., p. 215 (1893). 



The name Hipparchia was used by the older English 

 authors for the whole of the Satyritug, as was Satyrns by the 

 French. 



Dr. Scudder argues that PI. hyperanthus (Linn.) should be re- 

 garded as the type of this genus, to which there seems to be 

 no valid objection. 



Eyes naked ; antennae gradually thickened, or with a more 

 or less distinct club at the extremity. Wings with the sub- 

 costal and median nervures thickened at the base ; hind-wings 

 more or less dentated. 



This genus includes species of moderate size, from an inch 

 and a half to three inches in expanse. The wings are brown 

 or black, generally with a white or tawny sub-marginal band, 

 extending over more or less of the disc; the fore- wings are almost 

 always marked with a dark eye at the tip, with a white pupil, 

 and another towards the hinder angle, while there is a third 

 smaller eye near the anal angle of the hind-wings. In the 

 males the second eye on the fore-wings is often obsolete on 

 the upper surface, and the pale markings are less extended 

 than in the females, the latter being often considerably larger 

 than their partners. 



In another section of the genus the wings are dark brown
