Genus XII. ARGYNNIS Ochs. 



Ochs. Schmett. von Enropa, iv. 16. (1816).

Argynnis, Brenthis, Issoria, Acidalia, Argyronome, Hiibn. 



Head rather broad, hairy. 



Eyes nearly round, smooth. 



MaotnUce extending considerably beyond the thorax. 



Labial Palpi porrect, slightly ascending, divergent, projecting considerably beyond the head : the 

 first and second joints clothed with scales and long setiform divergent hairs ; the third joint 

 with scales, and more or less appressed hairs. First joint subcylindric, curved, about one fourth 

 the length of the second ; second joint slightly curved, much swollen beyond the middle, then 

 narrowed towards the apex, which is truncate; third joint very small, acicular, about one fourth 

 the length of the second. 



Antennas rather short, terminating in an abrupt pyriform club. 

 Thorax rather stout, rounded, oval. 



Anterior Wings trigonate ; the anterior margin rounded ; the outer about two thirds the length of 

 the anterior margin, sometimes slightly concave, sometimes nearly straight, often rounded ; 

 inner about equal in length to the outer margin, nearly straight. Costal nervure stout, 

 extending about three fifths of the length of the wing. Subcostal nervure slender, sometimes 

 emitting its first and second nervules near together before the end of the cell ; the third at less 

 than half the distance between this and the apex ; the fourth rather more remote from the apex 

 than from the third, sometimes emitting its first nervule before the end of the cell, its second at 

 about an equal distance from the first and third, its fourth nearer to the third than to the apex. 

 Upper disco-cellular nervule very short, sometimes almost wanting ; middle disco-cellular 

 curved inwards, longer than the lower, which is nearly straight, and anastomoses with the third 

 median nervule at some distance from its origin. 



Posterior Wings obovate ; the margins about equal, all rounded. Precostal nervule simple, slightly 

 curved, directed outwards. Discoidal nervule appearing to be a third subcostal nervule. Cell 

 closed by a slender disco-cellular, sometimes flexuous, sometimes nearly straight. 



Anterior Legs of the male fringed with long delicate hairs. Tibia smooth, rather shorter than the 

 femur. Tarsus shorter than the tibia, one-jointed, subcylindric, tapering towards the apex.
