Argynnis Behrensii, n. sp. 



Male. Expands 2.2 inches. Upper side dull fulvous, much ob- 

 scured at base; primaries bordered by two fine parallel lines enclosing 

 very narrow fulvous spaces between the nervules; resting on these a 

 series of small black crescents, each enclosing a fulvous spot ; the round 

 submarginal spots of medium size ; other markings as in allied species, 

 but lighter than in most. 



Secondaries have a double marginal line enclosing large fulvous 

 spaces; the lunules large, crescent, not quite touching each other or 

 the line; the rounded spots small; the median row confluent, forming 

 an unusually narrow band, much like that of ^1. Hcspcris ; on the arc 

 a recurved black spot enclosing a narrow fulvous space ; between the 

 submarginal spots and median line a row of pale fulvous spots cor- 

 responding to the second silvered scries beneath. 



Under side : primaries light buff, at base and along the nervules 

 pale ferruginous ; on hind margin and at apex dark brown ; the mar- 

 ginal spots sagittate, black next inner angle, deep brown above and 

 near apex lost in the ground color; the upper five enclosing silver 

 spaces; on the sub-apical patch three silver spots; other markings as 

 above. 



Secondaries of a deep, dense ferruginous, (much as in female Aphro- 

 dite) which occupies the whole wing except a narrow violet-brown 

 space between the outer rows of spots; these are twenty-one or twenty 

 two in number, all silvered, viz : seven submarginal, narrow, elongated, 

 edged above by broad ferruginous crescents; a second row of seven 

 mostly oval or pyriform ; a third of five, of which the first and third are
